MESSAGE FROM THE CEO

CIPHE INFLUENCES INDUSTRY

I would like to thank all those members who have responded so positively to recent communications and newsletters. The additional volunteers will be of great help with our technical projects and also with membership promotion activities.

Kevin Wellman, CIPHE CEO kevinw@ciphe.org.uk

IPHE is frequently invited to submit comments on various Government consultations. In January, feedback was given to the Institute for Apprenticeships on Occupational Maps and a separate consultation covering the Implementation of T Level programmes. The main thrust of the responses has been to ensure that fit-for-purpose training is available and that plumbing and heating is recognised as an occupation on its own merit. In addition, we have contributed to the London Assembly Planning Committee consultation on the use of sprinklers and the review of Building Regulations and fire safety. There have been many consultations over the years and one in particular is often raised in current discussions. In response to complaints from industry about a shortage of qualified engineers in 1977, the Government invited Sir Harold Montague "Monty" Finniston to set up a committee of enquiry into British engineering. The committee addressed the concerns that engineering was of relatively low status in the UK and in 1979, it delivered the Finniston Report. One of the main recommendations was that universities should offer engineering degrees (BEng and MEng) rather than just science degrees (BSc). This report also led to the establishment of the Engineering Council in 1982. Not all of the 78 recommendations were implemented and perhaps the most important one has been overlooked consistently by Government and engineering institutes alike. This was the call for a statutory register of engineers but at the time, a number of professional engineering institutes reportedly objected and the idea was once again shelved.

IMPROVED RECOGNITION FOR ENGINEERING PROFESSIONS I believe the appetite for better recognition of engineering professions is changing, partly as a result of lessons to be learned from the Grenfell Tower fire and other disasters. Nevertheless, it is sad that we have to wait for a disaster to occur before action is taken. I was pleased to hear that Severn Trent recently successfully prosecuted a company for causing pink water in Gloucestershire (see article on page 19). Whilst I welcome the prosecution, I hope that other water companies will follow their lead in two ways; firstly, to actively pursue contraventions and promote successful prosecutions, secondly, they should follow Severn Trent’s support for the CIPHE by signing into membership all their Water Regulation and enforcement staff.

CONCERNS OVER THE MCS SCHEME Following feedback from members regarding the MCS scheme and previous concerns expressed about the Green Deal, I have closely been monitoring developments of the ‘Each Home Counts’ review. Matters came to a head a few weeks ago when a number of associations united and wrote to Claire Perry MP, Minister of State for Climate Change and Industry, to raise their concerns. In addition to the CIPHE, signatories to the letter included: Heating & Hotwater Industry Council (HHIC); Association of Plumbing & Heating Contractors (APHC); Scottish and Northern Ireland Plumbing Employers’ Federation (SNIPEF) and the Institute of Domestic Heating & Environmental Engineers, (IDHEE). The letter contained the following three observations:

1. The implementation board is recommending that MCS and TrustMark operate the Quality Mark. This decision appears to have been made without due process and without a fair consultation. The heating industry also has grave concerns about the suitability of MCS to operate a quality mark due to the ongoing problems that the current scheme has. It is arguable that it has, in fact, had a distinctly negative effect on the renewables industry. Moreover, the failure to embrace long-established industry schemes would also make the Quality Mark anti-competitive. 2. The Each Home Counts implementation board has communicated to the press that whilst the scheme may be non-mandatory, they will be encouraging schemes such as ECO and Green Deal, plus third-party finance providers to require the scheme. We view this as an attempt to make the scheme mandatory in all but name and in conflict to the reassurances we have received in meeting with BEIS and the EHC chair. 3. The pursuance of such a Quality Mark which duplicates existing arrangements will certainly not be in the public interest. As far as I’m concerned, the scheme is not in the interests of installers and it will also be detrimental to the public. Watch this space for further news on developments.

ALL THAT’S HAPPENING IN THE PLUMBING & HEATING WORLD

ESSENTIAL GUIDANCE FOR DISTRICT HEATING SYSTEMS With the growing trend for district heating systems in the UK, the BPF Pipes Group has launched new guidance to promote best practice. District heating systems comprise one or more central heat sources instead of individual boilers. By pumping hot water or steam through a network of pre-insulated underground pipes the systems deliver heat from the point of energy generation to the end user. Generating heat in one central plant can be more economical than production in multiple smaller ones (such as individual households), which is one of the reasons why district heating is growing in popularity in the UK.

Like all systems using pressurised pipes, good design and installation ensures safety and maximises the long-term performance of such systems. So the BPF Pipes Group wants to encourage best practice through the use of correct procedures and the guidance covers key design codes, distribution pipework, British and European Standards and designing, installing and commissioning district heating systems using polymer pipes. The guidance is available at https://www.bpfpipesgroup.com/ support-downloads/guidance-notes/

District heating systems are growing in use in the UK

IDEAL BOILERS DONATES ITS TWO MILLIONTH LOGIC BOILER TO CHARITY

MANY CONSUMERS DO NOT SEE THE NEED FOR A CO ALARM

Ideal Boilers donated its two millionth Logic boiler to help support the vital work of a charity that improves the lives of homeless people across the UK. Emmaus, which has just opened a shop in Hull, supports more than 750 formerly homeless people, by providing them with a home for as long as they need it and work in social enterprises. Simon Collinge, Emmaus Enterprise Manager, said: “We are extremely touched and grateful to receive the two millionth Logic from Ideal. “This donation will help us raise the profile of homelessness and important funds for our community. The boiler will provide one household with the warmth our formerly homeless companions have gone without in the past.”

New research shows that 36 percent of households in Britain don’t have carbon monoxide (CO) alarms installed. The research, from online electrical retailer, reichelt elektronik, reveals that more than half (52 percent) of those without a detector say they are aware of what the detector is but don't feel a need for one at home. Additionally, nine percent are unaware of what a CO alarm is and why they would need one. In 2015, regulations came into force stating that every rented property must have smoke and CO detectors installed. A CO alarm must be placed in any room used as living accommodation and containing a solid fuel burning appliance. They should also be positioned at head height, a few metres away from the potential source according to UK Government recommendations.

VANS BENEFIT

For tax year 2018-19 the benefit of private use of a van increases from £3,230 to £3,350 and the fuel charge for private fuel provided increases from £610 to £633.

2018 AGM

The CIPHE’s 10th Annual General Meeting will be held on Friday 15th June at 11.00 a.m. The event has been kindly sponsored by Industrial Associate Supporter, AKW, and will be held at their premises in Droitwich Spa.

WATER THEFT Thames Water has hired private investigators to track down thieves stealing water from its pipes in an attempt to improve its performance as the worst company for leakage in the UK. Britain’s biggest water supplier, which supplies 15m people, or a quarter of the UK population, said that during the past six years the number of cases of unauthorised connections to its pipes had jumped from 33 in 2011 to 734 in 2017. The move comes as Thames Water is being investigated by regulator Ofwat. It was fined £8.55m in June for its “unacceptable failure” to control water leakages, with the equivalent of 180 litres leaking daily from every property the company supplies. Although Thames Water estimates just 2m-3m litres of water is stolen every year, it said the focus on theft was important because “any unaccounted-for water is classed as leakage in end-of-year performance tables”. The company currently loses 26 percent of the water it treats before it reaches the end user and it has deployed a team of eight former police detectives but is mostly relying on tipoffs from the public to find people lifting manhole covers and attaching illegal pipes to the water supply. They are also checking paperwork on new housing developments after discovering that some builders are connecting houses to the mains pipes without first seeking authority from the company, a spokesman said.

Branch NEWS LINCOLNSHIRE

TREVOR ROBERTS The Lincolnshire Branch announce with great sadness that Trevor Roberts, a retired Branch member, recently passed away. Trevor was a very kind and caring person and was an active member of the Branch, being both Chairman and President during his lifetime. He worked for Lincoln City Council and was well known in the Lincoln plumbing fraternity. He was a keen caravaner, belonging to an independent club called the Waggoners, and as such, was involved in the plumbing display caravan organised by the Branch at local county shows. He was a very keen club cyclist, and would often visit and deliver IOP news items to committee members who were poorly. He also had strong interest in the fiction hero, James Bond, and to that end, music from the Bond movies was played at his funeral. Our sympathies go to his wife, Judith, and his family.

BOILER PLUS SCHEME LAUNCHED Tim Sainty, CIPHE Membership Director tims@ciphe.org.uk +44 (0) 1708 463102

Boiler Plus is additional legislation that has been added to Part L of the Building Regulations. It comes into force on 6th April 2018 and introduces new standards that will apply whenever a boiler is installed in an existing heating system anywhere in England.

ome members have reported confusion about the requirements under the new scheme, so the following guidance should help to explain:

BACKGROUND In 2005, Building Regulations guidance set new performance standards for boiler replacements, increasing the number of efficient boilers, lowering costs for consumers and reducing carbon emissions. With advances in the technology produced by manufacturers, the skills of the system installer network and an increasing consumer awareness since then, the UK Government has introduced extended measures that will further raise the standards of the heating systems being installed in English households through a range of measures, collectively known as ‘Boiler Plus’.

THE BOILER PLUS SCHEME REQUIREMENTS • All gas boilers installed into existing systems in England must have an ErP efficiency rating of at least 92 percent. At the moment, approximately one in three boilers on the market fail to reach this standard so it will be essential that you check this before recommending and installing gas boilers for your customers. • Time and temperature controls must be installed at the same time if they are not already present and in full working order. Responsibility for verifying existing controls are in full working order will rest with the system installer. • Combination boiler installations must include at least one of the following additional energy efficiency measures to be installed at the same time: o Flue gas heat recovery system (FGHRS). Although a relatively expensive measure to introduce, recovering heat from waste flue gases to preheat the cold

08_member benfits.indd 8

journal

water entering the boiler is measured to deliver the same amount of heat as systems without it, whilst reducing gas consumption by up to four percent. o Load compensation. A common function in many smart controls and programmable thermostats; ‘load compensation’ devices measure the gap between the internal temperature of the household and what the user wishes it to be, modulating the boiler so it only uses the fuel required to close this gap. o Smart thermostat with automation and optimisation functions. The market for smart controls, giving consumers the ability to control their home temperature remotely via electronic devices has grown substantially in recent years. Including automation that will switch off the heating system when not required and optimisation to calculate and minimise the amount of work a system has to do to reach the desired comfort level, will be an acceptable means of complying with Boiler Plus requirements. o Weather compensation. The weather compensation controller alters the boiler flow temperature directly as the outside temperature changes, ensuring timely changes in the heat delivered to the system, increasing efficiency without reducing comfort. Whichever measure is chosen, it will be dependent on competent, professional installation and consumer advice from CIPHE members and the wider industry.

REGULAR AND SYSTEM BOILERS Although currently excluded from the above requirements (due to incompatibility with the controls and a potential risk of Legionella through under-heated water being stored in the hot water tank), any storage tank installed anywhere in the UK has required an ErP label of D or above since September 2017.

The Government has already expressed its intention to review its decisions regarding regular and system boilers in October 2018 and, again, in October 2022.

WHAT NEXT? The Department for Business, Energy & Industrial Strategy (BEIS) Heat in Buildings report from October 2017 (https://www.gov. uk/government/uploads/system/uploads/ attachment_data/file/651853/Boiler_Plus_final_ policy_and_consultation_response.pdf) makes clear that they already see there is further advancement of these standards to come, with time proportional and integral controls (TPI) and thermostatic radiator valves (TRVs) already under particular scrutiny. The Heating & Hotwater Industry Council (HHIC) have produced the flow chart in Figure 1 to help heating system installers in decision-making to comply with the new standards launched. Finally, although this legislation currently applies to England only, CIPHE would advise members across the United Kingdom and beyond to consider integrating this into best working practices and a minimum standard that puts the plumbing and heating industry at the heart of drive to increase energy efficiency and protect the safety, health and wellbeing of UK consumers. Making systems more efficient and effective will not only reduce costs for your customers, but will also decrease instances of those who are vulnerable choosing not to heat their home. The UK boiler market is the largest in the world, so CIPHE members and the wider industry can have a huge impact. Have you renewed your membership for 2018? If not, contact our membership department on +44 (0) 1708 463116 before it is too late.

have spoken to hundreds of learners and apprentices about the CIPHE and how we can support them, not just as new members, but throughout their career. Much of what I’ve talked about actually leads to the issue of professionalism and how important this is, not just in terms of maintaining one’s competence to do the job and to go on doing it, or just about concern for the health and safety of the public, but essentially, by abiding by a Code of Professional Standards which embraces all of this. Without guidance, it can sometimes be difficult to see the value of belonging to a professional body at the beginning of one’s training but with the right career support, access to educational content such as our ‘techtalks’ with invaluable input from the industry experts, our Industrial Associate Supporters, and the p&he Journal for example, we will see increasing numbers of those entering the profession continue their CIPHE membership and value its importance.

STAND OUT FROM THE CROWD Certainly the lecturers and tutors that I have met all across the UK have been very supportive, highlighting the fact that being a member of the CIPHE is a privilege and something to make you stand out from the crowd. An unexpected, but pleasing part of my travels has been to see how many of the staff have gone on to become members, appreciating that their membership provides an essential part of their own Continuing Professional Development.

South Devon College

There is an increasing number of opportunities and strands of specialism across the profession offered by many of the CIPHE Approved Training Centres, for example, South Devon College’s new facilities offer a wide range of renewable energy-focused education, including rainwater harvesting, biomass boiler, solar thermal and solar PV. It has its own Passivhaus with a mechanical ventilation heating system, which is used as a teaching resource on the plumbing and heating courses, while the system also controls services to the building. The college is also involved in community projects, installing and maintaining plumbing and heating systems for local companies and charities, providing invaluable real-world experience and skills for learners. Steve Willis Training Ltd in Burgess Hill is also maintaining its success and its apprentice places are oversubscribed. The centre offers hazardous situations in set-up rooms so that apprentices can learn in real-life settings and complete their assessments. The company is also attracting more women into the profession. I wanted to highlight some of the fantastic elements of CIPHE Approved Training Centres and could have selected any of them for this. I would particularly like to thank the following ATCs and their staff for their support: Canterbury College Croydon College EAS Mechanical East Kent College (Broadstairs)

• Electronic temperature sensing or thermometers. The installer would measure the temperatures of the radiator flow and return pipework and manually adjust the lock shield valves to achieve the correct temperature differential. • Bluetooth technology using an app. Grundfos has developed an app, which is connected to the pump via Bluetooth technology that guides the installer through the balancing procedure in a very quick and accurate way.

COVER STORY – CPD

Dealing with problem invoices – Part 2 In part 2 of his series about reducing the problem of late or non-payment of invoices, Peter Adkins of Emms Gilmore Liberson advises on the most effective way to chase overdue payments.

Peter Adkins. Director of Regulatory Services at Emms Gilmore Liberson Solicitors Email: padkins@egl-law.com

In the last smarttalk article (January/ February 2018 issue page 24) we wrote about the steps you should take to help reduce the problem of late or non-payment of invoices. However what do you do if the customer refuses to pay and what is the best way to chase payment? Knowing your customer is key. If you have taken the steps suggested in the previous article, you will know who is responsible for payment. 1. The first step is to make sure the invoices are delivered promptly and addressed to the right person. Your terms of payment should have been spelled out on your order forms, so refer to them again on the invoices. It is too late to simply put your terms of payment on your invoices. 2. Make it as easy as possible for customers to pay. Give your bank account details on your invoices for BACs payments. It is worth looking at one of the cheaper card payment terminals so you can take payment direct yourself.

not have to be complicated and you should stick to it – firstly, make a chasing call or follow up visit to the customer. Be polite, make sure there have been no problems with the work and then gently remind them that payment is now overdue. See if you can elicit an agreed payment date from them. Note any promises down and ensure you chase it. Make a diary note of when you made the call. 4. If there is still no payment and there are no problems, chase again after seven to 10 days. This can be by phone but preferably in a way that can be proven e.g. email or post. Many simply send a copy of the invoice with a polite but large ‘Payment Overdue’ stamp on it. Make a note of when it was sent. If you send by email, attach a copy of the invoice. If you’re dealing with businesses it is not unusual for them to stick to one or two payment runs a month, so ring the accounts department when you take the order and ask them where the invoice should be sent. You can also check that the person you are dealing with has the authority to place the order. Any order number that you are given should be quoted on all invoices. That way, you can ensure your invoice is reaching the right person. By now, if there are any problems with the work they should have been raised. If the customer does raise problems you

Pre-Action Protocol So, you have carried out the work, invoiced using your agreed payment terms, chased personally and by letter. You have asked if there are any problems and been told there are not. Now, you need to press harder and threaten action. You must ensure that you comply with a series of steps known as a ‘Pre-Action Protocol’. This requires the final letter to hit several buttons if you are threatening court action. Ignoring this process can cost you dearly, as you may have to pay the customer’s legal costs. The requirements of the protocol may seem a little daunting at first and are quite detailed, but if you have provided (and had accepted) a properly detailed order form and have invoiced correctly, you are most of the way there if you send copies of those documents using your own letterhead. This action normally finally reveals any alleged problems. The customer has 30 days to reply before you can consider issuing court proceedings. Next time, we discuss the issuing of court proceedings and the steps in a normal Small Claims action.

SMART HEATING IS THE WAY TO A MORE SUSTAINABLE LIFESTYLE Nigel Sanger, Divisional Director Technical Support at JG Speedﬁt

Nigel Sanger, Divisional Director Technical Support at JG Speedfit, reports on the growing consumer demand for zonal heating.

emand for smart heating has grown considerably in recent years, as people are becoming increasingly conscious about sustainability and reducing energy bills in a society struggling with fuel poverty. This is backed by the ‘Domestic Central Heating Market Report − Focus on Smart Heating Controls − UK 2016-2020 Analysis’ report. Even though UK homes with central heating have reached a saturation point, with 92 percent already having central heating installed, demand from housebuilders for smart heating controls has continued to increase. The rise of smartphone technology is driving consumer demand for convenience and cost savings in every facet of their lives − and heating is no exception. When it comes to heating your home, the convenience aspect of heating control is often just as important as energy efficiency. Installing heating controls comes with its own set of challenges but by taking a few key points into consideration, installers can tailor heating systems to meet the precise needs of end-users. This is where zonal heating plays an important role, by allowing homeowners to control heating in individual rooms. Zonal heating helps maximise cost and energy saving benefits and offers a more comfortable living space.

LIFESTYLES ARE KEY When considering which zones to include in a heating system, it is important to understand the routine of those living in the property. For example, bedrooms may not need heating

until occupants get home from work and school, meaning that a lower daytime temperature is more appropriate. When installing a heating system, it is essential to get a picture of the occupants' daily routine and when during the day they are most likely to need heating so it can be configured accordingly.

THINK INSIDE THE ZONE The term ‘zone’ is used to describe an area to be heated and controlled by one thermostat. Typically, a home will be sectioned into zones, with the temperature and heating duration tailored to the requirements of each zone. In many cases two rooms, such as an open plan kitchen and dining area, will be grouped together to form a single zone. So plan out your zones and agree them with the customer before installing the thermostats.

THERMOSTATS AREN’T FOR SHARING It is not uncommon for some installers and homeowners to try and use one thermostat to control more than one zone, but this is not considered best practice and is likely to waste energy. By using one thermostat to control multiple zones, the temperature of one room is likely to influence another. To avoid this and to make the most of cost and energy savings, it is therefore essential to use separate thermostats to control individual heating zones.

TAKE YOUR TIME As with most things in life, timing is everything. There is obviously no value in heating an unoccupied house. Programming individual zones in line with the occupancy patterns of the house is crucial to an effective smart heating installation. To do this effectively, end users must be provided with a user-friendly system which allows them to control the specific times that they want to activate their heating.

THE RIGHT CONTROLS Specify heating controls with smartphone accessibility

Simply installing heating controls in a home does not save money. Smart controls can

It is essential to use separate thermostats to control individual heating zones

be used to save money and energy but only when they are used in the right way. Heating only the rooms you will use is the most cost-effective method to reducing overall heating times altogether. Central to this is getting the right controls that people can use and have access to on the go. As is the case with anything, if it is too hard to use, people won’t use it. Specify heating controls that will offer software updates to keep them secure and up-to-date, as well as remote, smartphone accessibility for online and offline programming.

DON’T SUFFER A MELTDOWN A boiler is only as good as the device controlling it, so this is where the interlock function of smart heating controls can add real value, ensuring that the boiler is switched on and off as required. When the desired room temperature has been achieved, the interlock activates a cooling unit which is used to lower the overall temperature of the system. Using a poorly designed, inefficient, or unreliable interlock, will often result in energy wastage, which defeats the purpose of installing smart controls.

BATTLING BACTERIAL INFECTIONS IN HOSPITALS Tony Rheinberg, Senior Sector Marketing Manager at Armitage Shanks

Tony Rheinberg, Senior Sector Marketing Manager at Armitage Shanks, explains his company’s innovative approach to infection control in hospitals.

ospitals are presumed to be clean environments where sick people can expect to recuperate and improve. The last thing patients consider when they contemplate a hospital stay is that they will become even more ill by developing an infection, which has originated in their new, supposedly hygienic, surroundings. However, a report by the House of Commons, entitled ‘Reducing Healthcare Associated Infection in Hospitals in England’ has found that 300,000 people contract infections of this nature annually in this country. Part of the blame for the spread of bacteria rests in the layout of hospital washrooms and the characteristics of the sanitaryware products there.

A HAVEN FOR BACTERIA The very nature and purpose of sanitaryware, with the constant presence of water, means that it can be a haven for bacteria. Legionella grows and infection spreads from places such as basins, pipes and fittings if water has been allowed to stagnate. Standard glazed basins often have a surprisingly uneven surface when viewed under a microscope, making it easier for bacteria to stick to. Now, Armitage Shanks has taken a major step forward in clinical sanitaryware

design and is waging war on the bacteria in hospital washrooms by designing products, which help safeguard the health of patients and cut the risk of bacterial infections.

INNOVATIVE DESIGN Armitage Shanks’ Contour 21+ and Markwik 21+ product ranges have been developed in response to extensive research into where and how bacteria grows and they have been designed to ensure there is little opportunity for water to pool. Mixer taps have been identified as a potential risk area for harbouring bacteria, which has been found growing as far as two metres along the pipes from the outlet. The Markwik 21 + has an integral thermostat which enables water to be mixed closer to the point of discharge, eliminating the cold water ‘dead leg’ and minimising warm water areas, which can be a breeding ground for germs. Fittings designed in a way that allows water to reside are another prevalent source of bacterial growth. The Markwik 21+ counteracts this with waterways that have been reduced in size; consequently, the amount of water left in the tap is reduced by 34 percent. Keeping water on the move is essential if the fight against bacteria is to be won, as water-borne bacteria is much more likely to stick to surfaces and begin growing if water is still. Markwik 21+ features auto-flush technology. This guarantees that electronic fittings that are not in regular use, are flushed through with water every day. A hydro-purge facility flushes water through the pipework to ensure a debris-free system after installation and enables flushing after chemical disinfection. A manual thermal flush feature allows staff maintaining the product to override the thermostat and flush the fitting through with hot water to help reduce bacterial deposits.

ANTI-BACTERIAL PROPERTIES OF COPPER Copper has anti-bacterial properties which can delay the growth of bacteria or

journal

The Markwik 21+ features auto-ﬂush technology to keep water on the move

even kill it immediately. All fittings in the Markwik 21+ range are constructed out of more than 85 percent brass and contain antimicrobial copper components to reduce the likelihood of Pseudomonas infection. To prevent bacteria from building up in small crevices, Armitage Shanks’ designers have designed sanitaryware ranges which fit together seamlessly. The Markwik 21+ and Contour 21+ fully integrated tap and basin systems give bacteria little room to hide, offering the optimum in clinical hygiene. While Armitage Shanks’ sanitaryware has been designed to inhibit bacteria growth, human intervention is still required to give products a thorough clean. It is essential that hospital cleaners can easily access all parts of the washrooms in order to do their job effectively. They need to be able to strip all parts down to allow for complete disinfection and sterilisation. With the Contour 21+ tap deck back outlet basin and thermostatic mixer, thorough cleaning can be achieved as the water inlet is fixed onto the basin and isolated from the rest of the system using an allen key. This means that the whole tap can be easily removed and completely disinfected.

CERAMIC GLAZES On first inspection, the glaze of washroom ceramics may appear smooth and hygienic, not somewhere that would allow bacteria to flourish. However, when viewed under

FEATURE The Markwik 21+ product ranges have been designed to ensure there is little opportunity for water to pool

a microscope, many basins and ceramic surfaces are surprisingly irregular in appearance, therefore enabling bacteria to cling. In contrast, the Contour 21+ range has a SmartGuard glaze, which provides a much smoother surface; a place not conducive to the breeding of bacteria. If any viruses find a home on this special surface then their survival is likely to be limited; the glaze is impregnated with a silver ion which reduces bacteria multiplication. The design and shape of some wash basins could also be a danger to patients who have low immune systems and

Contour 21 sink

are therefore, susceptible to infection. Traditional basin design, in which water hits the surface at an almost perpendicular angle, can cause splashing and the transfer of bacteria living in washroom surfaces into the air and onto the face, body and surrounding area. In fact, this spreading of germs can reach two metres from the basin and towards patients’ beds. Armitage Shanks has created the HydroFin, which is part of the base of the Contour 21+ range. This ensures that water hits the surface at a gentle angle, cutting

splashing by 91 percent. Any germs which may be present will remain where they are, held in place by this effective design concept.

COMBATTING THE POOLING OF WATER The Contour 21+ basin also features advanced drainage in order to combat the pooling of water, which is a problem in some washroom products. Its simple waste assembly ensures that water drains instantly and vertically through a smooth pipe system. There are no steps or hanging points where water could pool. To enhance its streamline effect, the basin’s outer surfaces have thinner, more angular rims, steeper slopes and a smaller back area. The result is a design which avoids water pooling and is easier to clean. When considering the most suitable fittings and sanitaryware for healthcare environments, it is therefore worthwhile taking into account how the choice of product can impact on the level of hygiene, the patients’ recovery and the length of their stay. Armitage Shanks’ advanced healthcare solutions aim to ensure patients’ health improves from the moment they enter hospital as they recuperate in a clean and hygienic environment.

ANNUAL LECTURE

THE WORSHIPFUL COMPANY OF PLUMBERS’ ANNUAL LECTURE All CIPHE members are invited to attend the Plumbers’ Annual Lecture on Monday 21st May at the Royal College of Physicians, Regent’s Park, London.

ach year, the lecture is held to inform and inspire delegates from across the plumbing and heating industry, with a particular emphasis on sharing best practice and to stimulate forward-thinking discussions supporting and promoting the craft. This year, Master of Worshipful Company of Plumbers, Robert Burgon, has asked Professor Mala Rao OBE, an international expert on public health and the role played in it by the plumbing industry, to deliver the lecture. This provides a unique opportunity for CIPHE members to hear from Professor Rao, who has a vast knowledge and understanding of the industry obtained throughout her career, which includes being the founding Director of the Public Health Foundation − India’s first Institute of Public Health.

Additionally, Professor Rao has delivered many talks at World Plumbing Council meetings, including the World Plumbing Conference in Edinburgh in September 2011. She made a video in support of World Plumbing Day, which has been shown in many countries around the world.

LINKING PLUMBING, HEALTH AND CLIMATE CHANGE Robert Burgon believes that this year’s lecture will shed light on important issues such as how plumbing, health and climate change are all linked. He said: “For CIPHE members, this is of particular relevance, due to increasingly stringent regulations when it comes to installing and servicing heating and water appliances, in order to protect both the public and the environment. This

has recently been demonstrated by the long-awaited ‘Heat in Buildings’ policy, designed to maximise the efficiency of replacement boiler installations, as well as to reinforce some existing Building Regulations. The background to the policy is that the UK Government has committed to lowering its CO2 emissions by 80 percent before 2050 and there is no doubt that replacing older boiler stock will be of benefit to the public – for their safety and comfort. Mr Burgon is also keen to reflect on the wider issues at play when it comes to the impact of poor plumbing infrastructure, saying: “Professor Rao will be talking about the effect that plumbing and heating has on public welfare, using examples of how poor plumbing infrastructure has caused negative implications for people in developing countries. Everyone in the industry can benefit from learning about these issues and how the noble plumbing and heating profession can improve the wellbeing of others.”

TO BOOK YOUR PLACE The lecture is open to anyone with an interest in the subject. CIPHE members can also count attendance towards their continuing professional development (CPD) hours. Further details will be placed on the Worshipful Company of Plumbers’ website nearer the time (www. plumberscompany.org.uk) and tickets can be purchased through the website. There will be the option of attending the lecture on its own (which is preceded by tea and biscuits from 17.00) or attending the lecture and the dinner that follows. The event is also an opportunity to network with like-minded individuals committed to excellence in plumbing.

CASE STUDY

PINK WATER – CROSS CONTAMINATION INCIDENT Lee Rawlings ACIPHE RHP, Senior Water Fittings Regulations Technician at Severn Trent, reports on the pink water contamination investigation in Gloucestershire, last summer.

ast summer, Severn Trent was Lee Rawlings contacted by ACIPHE RHP, local residents Senior Water from Newent, Fittings Regulations Gloucestershire, Technician at regarding their Severn Trent water quality, in particular, that their mains water supply was discharging pink water from their kitchen taps. Our immediate response was to undertake rigorous water quality sampling upstream and downstream of the affected properties and to issue ‘do not drink’ notices. This ensured that we safeguarded public health while trying to establish the root cause of the contamination incident and guarantee the safe return of the public water supply. Knowledge and experience has taught the Severn Trent Water Fittings Regulations team that when faced with contamination incidents of this nature, the root cause is normally associated with backflow, caused by negative (low) pressure, resulting in contaminated fluid being drawn back into the cold water supply as a result of back siphonage or back pressure.

During my initial investigation that afternoon, I identified a number of greenhouses located behind one of the affected properties, so using my detective instinct, I investigated the third party plumbing arrangement further. My understanding of the local area quickly established that the site in question had access to its own private borehole supply, predominantly used for irrigating crops.

THIRD PARTY PUMPING SYSTEM The third party pumping system consisted of an underground submersible pump, used to pump borehole water from below ground into two large, interlinked cold water storage cisterns. The stored water supply was then boosted, using an external floor-standing pump set (running at 6 bar) to feed four inline chemical mixing units. The mixing equipment was used to collect and mix a concentration of pink strawberry fertiliser, which was then distributed under pressure to a number of hose union bib taps located at various points around the site. Upon further inspection, I noticed a yellow ‘commercial’ hose installed in one of the external greenhouses, which I traced back to its point of connection, in this instance; to a vertical standpipe arrangement. Further questioning established that the yellow hose and adjoining underground pipework had been installed in a manner that allowed the third party to directly cross-connect the private irrigation system to the incoming Severn Trent public drinking water supply. Once my suspicions were confirmed, I instructed the customer to immediately disconnect the cross-connection.

SUCCESSFUL PROSECUTION

The installation of the chemical ‘Venturi’ units used to mix the strawberry fertiliser with the boosted borehole water supply

At this point, we had substantial evidence to indicate that the third party cross-connection was directly linked to contaminated fluid (from the site) being pumped back into the public drinking water network through the customer’s private irrigation system. Following an interview under caution, we concluded

that the private pump set arrangement was operating at a greater pressure than the public water supply pressure, therefore, an increase in back pressure resulted in strawberry fertiliser being pumped back into the public drinking water network turning the water supply pink. Due to the serious nature of the incident, Severn Trent took legal action against the customer for gross misconduct and the case was held on 18th December 2017. Haygrove Ltd of Ledbury, Herefordshire, pleaded guilty at Hereford Magistrates Court under sections 73 and 174 of the Water Industry Act, for contraventions of the Water Fittings Regulations – which ultimately led to a contamination incident in the village of Newent, Gloucestershire in June 2017. As a result of our prosecution case, Haygrove Ltd were ordered to pay £11,707.78, including costs.

UFH SYSTEM CONTROLS AND WIRING Martyn Frost, Chairman of the CIPHE Controls Technical Working Group

There are many ways to install underfloor heating (UFH) systems and many different controls. So in this CPD article, Martyn Frost, Chairman of the CIPHE Controls Technical Working Group, concentrates on one of the most common.

• fused spur; • main wiring centre (Figure 1 shows two zones, but these wiring centres normally have eight zones); • room thermostat; • programmable thermostat; • manifold actuators; • UFH pump; and • boiler and system pump. Therefore, as always, we should start at the fused spur using a 3-amp fuse, and then starting from ‘cold’ all thermostats will be in the ‘demand’ position. Some of the letters representing an individual terminal (such as N) are obvious, but others are not. I will go through them

n this particular system, there are four main component parts (but several dozen items). 1. UFH pipe; 2. UFH manifold (normally in two port, up to 12 port configurations); 3. Mixing unit (comprising an UFH mixing valve, pump, fittings and very often an overheat thermostat; and 4. Controls. For the purposes of this article I will ignore the pipe, as there are far too many types to go into in any depth. In Figure 1 you will note that there are many items, and in flow (electrical) order these are:

all as we move forward in this article, apart from terminals 1 and 2 − the night set back timer (NSB). Some UFH systems require a NSB function to operate correctly. If that is the case, then one would need to connect a time function to either terminal 1 or terminal 2 to provide that function. We take a ‘live’ and a ‘neutral’ directly to the eight-zone wiring centre, which in the event of a time control not being fitted, would make the Ls on all eight zones permanently live − as shown in Figure 2. (A time switch can normally be fitted if required and if one is fitted to the Ls on all zones, they would only become live when

the time switch is on.) Now that the L is live, it is sending voltage out to a room stat or programmable thermostat (Figure 1). As stated earlier, the stat is in the demand position so that it will now send voltage back to terminal A in Figure 2. Terminal A is connected to the two terminal Rs, which are the live supplies to the manifold actuators seen in Figure 1 and in this wiring centre, there are two actuators per zone. Once terminal A activates terminals R (and if the neutrals of the actuators are connected) the actuators will start to open (a major point to note here; is that most actuators will take up to around three minutes to open up fully). At the very same moment that terminal A becomes live, the two relays energise to make their switches (another major point to note here is that most of the relays on this type of wiring centre are ‘volt free’ but NOT all of them are; some have one volt-free and one at supply voltage and some have two volt-free relays. In either case, any volt-free relays need to have a live connected to it to supply anything that needs a supply voltage). Whatever voltage is connected to a

volt-free switch should be the voltage that is supplied out to whatever item is requiring a supply (as shown in Figure 3).

WIRING CENTRES Now we have established that the relays have the required voltage output, one of the relays is connected to the system boiler and its pump and the other relay is connected to the UFH pump. There are two types of UFH wiring centres when it comes to the relays: 1. One where the relays activate immediately when terminal A becomes live; and 2. One where the relays delay activating for five minutes when terminal A becomes live. If you use the first type, you run the risk of pumping against a dead head as the pump comes on before the actuators open, which the second type overcomes as the pump does not run until the actuators open. So, as the relays have engaged the system boiler and UFH pump, water will now flow within the UFH pipe circuits.

WATER TEMPERATURE As the UFH system usually takes its flow and return off the main system, we will now

have water at approx. 82°C arriving at the UFH manifold. Water at this temperature going into an UFH manifold would be far too hot to use, so the water temp must be reduced prior to it entering the circuit. 1. The high temperature water now enters the UFH mixing valve, which will reduce the temperature down to anything between 35°C and 45°C. 2. Beyond the mixing valve, the flow will go through the UFH pump and then through the open actuator into the calling circuit. 3. There are flow meters on the UFH manifold with which to set the specified flow rate. The water will flow around the circuit and back to the return side of the mixing valve, then back to the system boiler. Finally, it is imperative that the flow temperature is controlled, so that it does not exceed the desired temperature and overheat the floor. To that end, an overheat stat is normally included to ensure that any spike that occurs in flow temperature from the mixing valve shuts the pump off.

TRAINING MATTERS

TRAINING MATTERS ALL THAT MATTERS IN THE TRAINING WORLD

A NEW APPRENTICE STANDARD? There is a lot of excitement around a potential new era of education and training for the industry, but it is impossible to ignore the continuing negative press regarding apprenticeships since the introduction of the Levy in 2017.

Jenni Preston, Editor of Education & Training Matters for Plumbing Lecturers (ETM)

he Plumbing and Domestic Heating Technician Trailblazer is almost here and organisations, including the CIPHE, are welcoming the new apprenticeships with open arms. Here, we look at some of the key issues around Level 2 and what Trailblazer means for apprentices, training providers and employers.

TRAILBLAZER AND LEVEL 2 The new Trailblazer apprenticeships for plumbing and domestic heating are Level 3 qualifications. With the support of employers and colleges, increasing the standards of those entering the industry to Level 3 will be a good thing. The CIPHE has long urged trainees to stay on and attain a Level 3 qualification, believing it best preparation for a career in plumbing and heating engineering, but what does it mean for those currently undertaking the NVQ Level 2 qualification? Is it redundant? Will they get the chance to stay on until Level 3 or will all current courses cease to exist the minute Trailblazer is ready to roll out? The reality is that while ever there is demand, Level 2 qualifications will continue to exist. It is already confirmed that both the old and new systems will have some overlap, with the new Apprenticeship Standards running alongside the old Apprenticeship Frameworks for a time. City & Guilds expect the changeover will be complete by 2020, but this date is not set in stone. In the meantime, those starting on Level 2 courses should be mindful of CIPHE’s recommendations to continue education until Level 3 is achieved. For apprentices and their employers planning for education starting in the 2018 and 2019 academic years, the choice

24_training.indd 24

journal

will be between starting on an established course on an outgoing model or to have faith in the new Trailblazer course launched. The introduction of new T Level qualifications was announced in October last year. Set to be developed between now and 2022 − with the first phase starting in September 2020 – these new qualifications will give technical subjects equal status alongside A Levels. Construction will be in the first wave of subjects available, with courses at both Levels 2 and 3. It is hoped that putting technical and academic qualifications on an equal level will encourage more students into vocational education – something that will be vital to the UK’s future, post-Brexit. As the Government explains in its T Level action plan: ‘T Levels’ are new technical study programmes that will sit alongside Apprenticeships within a reformed skills training system. Study programmes based around a T Level will generally be studied over two years and will include a new technical qualification, which may be taught in a classroom, workshop or simulated work environment. The programme will include a substantial work placement of up to three months as well as English, maths and digital content.’ It is not clear what T Levels could look like for plumbing or heating subjects. A classroom-based plumbing or heating T Level would be no match for a four-year apprenticeship (and neither should it be peddled as an alternative option). However, for those at 16 who have not yet chosen their vocation, completing a T Level would give them a glimpse into the industry while also proving they have brains as well as brawn. With flexibility in the length of

apprenticeships, we may see a wave of young engineers taking the T Level route before entering an apprenticeship, where due to knowledge already gained, they can be fast-tracked through a shorter apprenticeship. Alternatively, T Levels could potentially be a first step onto a career in R&D or manufacturing – areas that are vital to the continued success of the industry.

TRAILBLAZER – THE FACTS Conjecture about T Levels aside, it seems that there is still a lot of confusion about what Trailblazer brings to the table, but some facts are certain: For the training provider there’s a new curriculum to learn and deliver. There are new areas to assess, new grading systems to learn and there will be some re-training required too. The new apprenticeships will be extensive and a challenging learning environment for everyone; tutor, apprentice and employer alike. For the employer, taking on an apprentice is a much longer-term commitment. Apprentices need time and meaningful employment to get the best out of their training. However, apprentices should not be considered a drain on resources, but an investment that will deliver a more competent, better qualified employee even before the conclusion of the training. The Education and Skills Funding Agency (ESFA) recently announced that the funding allocated to the apprenticeship standard is band 13 for new starts from 22nd January 2018. The upper limit of this band is £21,000. For the apprentice, they will be starting out on a totally new qualification that has had a huge amount of time devoted to its planning.

TRAINING MATTERS

DURATION As stated, the ‘typical duration’ is expected to be up to 48 months. However, this time can be reduced if the apprentice has advanced knowledge and skills, which are formally known as ‘Accredited Prior Learning’ (demonstrating how the T Levels come in). All of the wide-ranging Plumbing and Domestic Heating Technician Standard’s core skills, behaviours and knowledge must be mastered, with a 12 month period spent specialising in a chosen field.

On-programme knowledge assessments 45 Months

Although, time to complete is not fixed and is dependent upon apprentice and employer commitments alike, a 40-48 month duration is anticipated.

Individual employers will be the ones to determine what their entry requirements will be, however there is an expectation that apprentices will hold English and maths qualifications at Level 2 on entry – those who do not must achieve that level prior to taking their end-point assessment. Additionally, the newly developed Level 3 Plumbing and Domestic Heating Qualification must also be achieved prior to taking the end-point assessment.

ENGTECH AND CSCS CARD REGISTRATION: One of the most exciting additions to the new apprenticeship is the eligibility (upon application) of professional registration with the Engineering Council. By the end of their apprenticeship, the apprentice must satisfy the requirements for registration as an Engineering Technician (EngTech) by the Engineering Council, through membership of the CIPHE or another professional engineering Institution. Additionally, apprentices need to complete a health and safety assessment to satisfy the requirements to obtain a Construction Skills Certification Scheme (CSCS) Card through the Joint Industry Board for Plumbing and Mechanical Engineering Services (JIB-PMES) at the appropriate grade.

STRUCTURED STUDY Apprentices will need to follow a structured study programme alongside suitable employment and high-quality training and assessment. There is to be a mandatory end-point assessment once the other pre-requisite challenges and qualifications

Professional Discussion

have been met (this includes the Level 3 Plumbing and Domestic Heating Qualification, and Level 2 English and maths). The end-point assessment measures the apprentice’s ‘whole job competence’ in the very final stages of their apprenticeship.

THE END-POINT ASSESSMENT The end-point assessment is broken down into different elements: • knowledge; • performance; and • pathways and behaviours (optional). Of this, the knowledge element will be made up of a 50-question multiple-choice test and seven-hour design project. The performance element will include a six-hour practical installation test and a

practical application test, where they will be assessed on their fault finding and servicing skills. The optional pathways and behaviours element is assessed through professional discussion and supported by the production of a workplace log book completed by the apprentice during the end-point assessment period, with at least eight weeks to complete, after the gateway.

HEALTH AND SAFETY

GETTING YOUR PRIORITIES RIGHT: SCALD INJURIES IN HEATING ENGINEERS

Sam Coulson MBChB, MRCS(Ed) ST3 Registrar in Plastic Surgery

Mr S. G. Coulson1 MBChB, MRCS (Ed), ST3 Registrar in Plastic Surgery and Mr N. A. Martin1,2,3 MBBS, MD, MSc, DMCC, AKC, FRCS (Plast), Consultant Burns Surgeon, write that a large number of burn injuries in the UK are preventable, consequently, so is the associated morbidity and mortality. Here, they present two cases sustained by heating engineers during their normal working activities.

cald injuries are the most common cause of thermal injury in patients seen by UK burns services.1 In the UK, the mortality rate is 1.12 percent despite modern burn care and, worldwide, such injuries are the primary cause of an estimated 180,000 deaths annually.1,2 Burn injuries can result in significant morbidity, including loss of function, scarring, hospital admissions, multiple procedures, years of physiotherapy,

mental health problems, loss of employment and diminished earning potential.

REFLEX ACTIONS In both cases, the engineers were working on the hot water feeds from storage systems in business premises. During routine procedures, leaks occurred from the feed pipe and both engineers responded involuntarily by placing their dominant palm over the pipe

Figure 1. Intra-operative image of the palmar aspect of left hand following debridement of the burn injury

26_burn.indd 26

journal

while colleagues turned off the flow. Both engineers stated that their first reaction was to prevent â&#x20AC;&#x153;damageâ&#x20AC;? to the surroundings. Both applied appropriate first aid by running cool water over the affected area for 20 minutes and sought medical attention. In the first case, the burn was confined to the palm of the dominant hand and was relatively superficial. It did not require surgical intervention and was treated with dressings

HEALTH AND SAFETY

for several weeks until healed. The patient was unable to work during that time but has since returned to full employment. In the second case the burn was more significant, destroying the majority of the palmar skin of the dominant hand and a number of tendons and nerves. [Figure 1.] The patient was admitted to the regional burns centre and stayed for more than a month, requiring complex reconstruction with a two-stage procedure that transferred skin from his groin to the injured palm. [Figures 2 and 3.] Further operations have been carried out in order to separate the fingers, reduce tissue bulk and improve the potential functional recovery. This patient will have continued follow up, including intensive hand physiotherapy, for many years and may yet require further procedures.

DISCUSSION The storage and distribution of water at hot temperatures is an essential part of the infrastructure of many industrial, business and domestic premises. The risk of injury increases with the water temperature and, on the whole, is mitigated by Health and Safety legislation.3,4,5 When working on hot water pipes, or any pipework carrying potentially hazardous material, it is imperative that steps are taken to prevent injury. The placing of a dominant hand over a sudden leak may be a reflex action to protect the face or torso but would not be necessary if the feed pipe had been turned off. In one case, the engineer stated that he did not want to damage a newly laid floor but, admirable as his intentions were, the floor can be replaced much more easily than a palm.

LIFE-CHANGING INJURIES The authors wish to raise the awareness of serious injury to all personnel working with pipework carrying hazardous substances. Even though one patient was treated without an operation; his wounds required numerous uncomfortable dressing changes over several weeks and resulted in loss of earnings. The second case highlights how life-changing injuries can also result from such an event.

Figure 3. Intra-operative image of the left hand four months after the 1st stage procedure, having undergone further debulking of the skin flap

ADVICE 1. Health and Safety legislation and safe working practices prevent serious injury and must be followed. 2. Never use a hand to prevent escape of fluid; if necessary to prevent further injury, use an interface material.

3. F irst aid is imperative; remove affected clothing, including rings and jewellery, and apply cool, running tap water for 20 minutes before seeking specialist medical attention.

EXTERNAL AFFAIRS GROUP

UPDATES FROM THE EXTERNAL AFFAIRS GROUP SHOUT ABOUT BEING ‘PROUD

GROWING AS PROFESSIONALS

TO BE A PROFESSIONAL’

AND PEOPLE

Richard Soper, Director of Development at the CIPHE, encourages members to wear and display the CIPHE badge with pride.

he CIPHE and its members are on a mission to stamp out unscrupulous practice in the plumbing and heating industry and protect vulnerable consumers. While we are all aware of this, are your customers? The next questions is, if not, why not? It is so important for those who stand up for professionalism to be loud and proud about it. One way of doing this is for all members to display the CIPHE badge with honour – whether on your van, website, office paperwork, or other day-to-day items you use for your job that customers will see. This is a simple, yet effective way of showing off your commitment to the occupation and it raises awareness of the fact that you are aligned with a professional body. Increasingly, consumers are researching their options and in the vast majority of cases want to know that they are only welcoming qualified professionals into their home. Your CIPHE membership is yet another way of demonstrating this, as unscrupulous workers just won’t have one, and won’t be accepted if they don’t have the necessary proof of qualifications and expertise. We’d like to hear from proud members of the CIPHE and encourage you to send in your images of how you display the CIPHE badge with honour. Please email your photos to Membership Director, Tim Sainty at tims@ciphe.org.uk

rom my position within the CIPHE, and as an employer working within the UK bathroom, plumbing and heating industry, I know first-hand the value that investing in your own personal development can bring. We often talk about continuing professional development (CPD), which is the furthering of knowledge and skills throughout your career, but personal development, the practice of developing the qualities you need to be a professional and the self-awareness required to reach your full potential, can be neglected. The good news is that CIPHE members, at every level, are in a position to grow their skills and increase confidence in lots of different areas. Since launching the Proud to be a Professional campaign in 2016, the CIPHE has gone above and beyond to improve the quality of training and skills – not just technical, but also to support members with their own marketing, how to find an apprentice and be a good mentor, and more. It is the talented and hardworking people in our industry who make such a difference to the experience consumers have. It was excellent to see last year for instance, the quality of CIPHE Apprentice of the Year entrants. All of whom showed great knowledge, understanding and empathy to the customers they served. We know that they have, in turn, been mentored by seasoned professionals, who are a credit to our industry too. I urge members to prioritise both their technical and personal development this year – perhaps by taking on an apprentice, which is a very rewarding experience both for character-building and professionally, or by simply getting in touch with the CIPHE to discuss your aims and ambitions to see how we can help.

PRODUCT SAFETY AND STANDARDS Yvonne Orgill, Director at European Water Label and voluntary member of the CIPHE External Affairs Group, explains how the new Office will further help to protect consumers.

he Government’s launch of the new Office for Product Safety and Standards, on 21st January 2018, will enhance product safety in the UK and importantly, give consumers a higher level of protection. For the plumbing and heating industry this provides assurance that gas, electric and water appliances, will be part of the Office’s remit when assessing the risks and managing responses to largescale product recalls and repairs. Additionally, the Office will also carry out border checks on imported products once the UK leaves the European Union.

28_external affairs1.indd 28

journal

At a time where international trade and the growth in online shopping is expanding, the Office adds another layer of protection for the consumer when buying goods. Importantly, this doesn’t take the onus off manufacturers, importers and retailers – who legally, must still ensure that products are safe. However, what it does do is provide reassurance for consumers, who can be safe in the knowledge that a system is in place if products need to be repaired or replaced. With £12 million per year funding being made available to the scheme when fully operational, it should mean even better support, including aspects of product testing and technical expertise.'

FIRST 2018 IADG MEETING A SUCCESS Tim Sainty, CIPHE Membership Director, reports on the first Industrial Associates Development Group (IADG) meeting of the year, and how the CIPHE will be driving a number of new initiatives and membership services with its Industrial Associates (IAs) in 2018.

Paul Massey, IADG Chairman, addresses delegates

t is a real pleasure to report that the first IADG meeting of 2018, held in February at the Builder’s Merchant Federation, Coventry, was a great success.

WELCOMING NEW FACES A number of new IAs attended, including representatives from Heatrae Sadia, Henkel, Monument Tools, Plumbase, SNG Publishing, Systemlink Technologies & Tracpipe; highlighting that more IAs than ever are taking an active interest in the CIPHE’s work on behalf of the plumbing and heating industry and our relationship with our members.

2017 SUCCESSES AND 2018 PLANS As this was the first IADG meeting of the year, the main objectives were to update and inform IAs on the Institute’s 2017 achievements and its plans for 2018. Readers of the p&he Journal will already know what a great year the CIPHE had in 2017, including the fact that IA membership increased by seven percent, in addition to a two percent growth of other CIPHE

membership categories. Not only this, we also received more than 350 pieces of positive coverage in the trade and consumer press last year, helping us to promote the professionalism of our members and to highlight the importance of raising industry standards. Delegates at the meeting also heard how 2018 is going to be yet another packed year for the CIPHE. A large focus for the Institute will be on the development of a consumer home compliance health check covering all aspects of home plumbing and heating. A focus group, including other representative bodies from the industry, was held on 24th January 2018 to discuss what this could look like, and interested members are invited to be part of it. For more information please email Richard Soper, Director of Development for the CIPHE at richards@ciphe.org.uk

PROUD TO BE A PROFESSIONAL As always, the Institute’s ‘Proud to be a Professional’ strapline was displayed and communicated at the event. Collectively, if all members wear the CIPHE badge and make a point of showcasing their involvement with the Institute, even more awareness of our united commitment to professionalism can be achieved. Badges were provided at the event and additional ones can be requested.

AR AND VR CPD The CIPHE Augmented Reality (AR) and Virtual Reality (VR) Continuing Professional Development (CPD) resources will be launched this year and will offer members a unique, digital learning opportunity. The technology was demonstrated at the IADG meeting to show how, through innovative gaming-style learning experiences, members will be able to earn CPD recognition from the CIPHE.

INDUSTRY REMINDERS Updates provided by Kevin Wellman, CEO of the CIPHE, and Paul Massey, IADG Chairman, covered the impact of Grenfell and CIPHE’s involvement in the ongoing enquiries and responses, as well as education initiatives including Trailblazers and industry planning for Brexit. EGL and Ilicomm Technology Solutions provided delegates with an update on what the new General Data Protection Regulation (GDPR) legislation means for businesses and their responsibilities when processing and retaining data.

MEMBER INTERVIEW

SECOND GENERATION APPRENTICES Steve Willis Training Centres achieved CIPHE Approved Training Centre status almost four years ago, this accolade recognises excellence in training in the plumbing and heating industry. Here, we speak to MD, Steve Willis, to find out how he began as an apprentice and now, is starting to train a second generation!

teve Willis Training Centres has provided gas, plumbing and electrical training for over 17 years now. From small beginnings, the business has expanded to include five modern training units in two locations (Burgess Hill, West Sussex, and Portchester near Portsmouth). Both locations offer modern, purpose-built workshops and classrooms and have close relationships with leading manufacturers across the industry to ensure that trainees have access to the very latest equipment. Their training staff have all been engineers themselves – as the theory is that there is no substitute for industry experience! Steve started out on a government training scheme when he left school in 1981, and a six month placement with a local plumber led to an apprenticeship. He then worked as Steve Willis

a qualified plumber, moving on to spend 13 years in an FE college before finally setting up his own training business in 2000. Steve said: “I am a firm believer in the importance of providing professional training of the highest standard, and I am proud of the excellent reputation that my company has built up across the industry.” A CIPHE approved training provider since 2014, Steve Willis Training is one of only a handful of centres in the country to offer such a wide range of gas courses, and sees almost 3,000 plumbers and heating engineers a year for training and assessments.

APPRENTICES As a former apprentice himself, Steve is pleased to see the apprenticeship training side of the business going from strength-to-strength. While there has been some negative press coverage and even talk of a skills shortage, plenty of young people remain keen to take the apprenticeship route. Those that Steve Willis trainers meet at careers fairs and at their own open days are focused and knowledgeable and ready to start their careers. The opportunity to ‘earn while you learn’ definitely compares favourably to the high cost of going to university. Last

year their courses were oversubscribed even before the GCSE and A Level results came out and more apprentices started in September 2017 than ever before. Apprentices training with Steve Willis are supported from the day they come in for their initial assessment right through until they celebrate their qualification at the Apprenticeship Graduation Evening. Employers benefit from the experience of the apprenticeship team, who understand their requirements and provide a specialist service which can even include finding them an assessed and vetted apprentice, suited to their particular business needs. The quality of their training was recently recognised when they successfully tendered to supply the Education Skills and Funding Agency non-levy funded apprenticeship training, so they are now approved to deliver apprenticeships for both levy paying and non-levy paying employers. Steve says: “Running short courses and apprenticeship training side-by-side benefits everyone − the apprentices immerse themselves in a professional working environment alongside experienced tradespeople completing their own revision and assessments. “In turn, employers can see the apprentices studying hard and remind themselves of what taking on an apprentice could do for their own business. “It is a source of great satisfaction to everyone at Steve Willis Training that we are now starting to see a second generation come through the training centres. Former apprentices who have gone on to set up small plumbing and heating firms are now sending their own apprentices to train with us, and we can’t ask for a better endorsement.”
