Elmhurst Energy Other Accreditation Schemes

Welcome to the latest edition of Elmhurst’s Energy Matters magazine.

As we delve into the current landscape, it feels like we are navigating through a vacuum of new Government initiatives and policies surrounding energy efficiency in the built environment. With the general election now announced for 4th July 2024, one thing remains certain: the imperative to reduce energy consumption, lower bills, and cut carbon emissions in the built environment needs to be accelerated.

Adding to this complexity, the UK’s approved methodology for assessing the energy performance of existing dwellings (RdSAP) was originally due to be updated in Spring 2024 (from RdSAP 9.94 To RdSAP 10). However, Elmhurst has since been informed by government that the release of RdSAP 10 has been delayed until later in the year. We will continue to update members on its progress.

On a brighter note, our conferences continue to deliver key updates and industry insights for energy and retrofit professionals nationwide. The National Conference in Leicester was jam-packed, featuring invaluable contributions from government and academia. We have recently visited Edinburgh (15th May) and will next be en route to Cardiff (26th Sept) and Belfast (12th Nov). While we understand not everyone can attend, for those who can we extend a warm invitation. Our conferences offer the opportunity to connect

with fellow professionals, ask the experts your questions and air your concerns for the future.

The Future Homes and Building Standards consultations have dominated industry discussions so far this year. Due to be implemented in 2025, we eagerly await government feedback on this ambitious initiative, which stands to revolutionise energy efficiency in the built environment, setting the standard for low-carbon homes and buildings as we march toward netzero emissions.

Anticipation is also mounting for the consultation on the ‘EPC action plan’, wherein the Government will outline its plans to improve the infrastructure and delivery mechanisms with an aim to improve the quality of Energy Performance Certificates (EPCs). This includes the training, format, methodologies and much more.

While the pace of home retrofitting remains slower than ideal, we are delighted to see the increasing use of real measurement to help inform good choices, whether this is through the use of Background Ventilation Testing or newer spaces, such as in situ U-Value or Heat Transfer Coefficient tests. The world is certainly changing quickly and all with the aim of improving people’s homes and businesses.

The value proposition of our members’ contributions continues to soar. Whether it’s EPCs, DECs, Air Conditioning Reports, Air Tightness Tests or a myriad of other services,

the importance of engaging competent professionals is critical. This is a message that we continue to convey to all stakeholders.

Finally, I am delighted to see the new format and design of our industryleading magazine. I hope that you enjoy the articles inside, and I wish you a wonderful summer ahead.

Changes Coming to 'EPC Data' Sharing Rules

A long-awaited amendment to the Energy Performance of Buildings Regulations, which underpins production of Energy Performance Certificates (EPCs) in England and Wales is due to come into force on 24th June 2024.

The amendment paves the way to allow for government, accreditation schemes and energy assessors to share energy assessment and EPC data with property owners, occupiers, landlords and third parties with their consent.

Why is this important?

Registered Social Landlords own and manage some of the most energy efficient properties in the UK due, in part, to the enthusiastic use of EPCs and energy data, alongside schemes such as the Housing Health and Safety Rating System (HHSRS).

Since December 2021, accreditation schemes, including Elmhurst, have been unable to supply the comprehensive energy data that sits behind every EPC as a result of a legacy restriction within the primary legislation that was designed to prevent misuse by commercial operators.

Elmhurst, working closely with other industry stakeholders, have been lobbying hard for this position

to change and we are delighted to report that a draft amendment to primary legislation was considered in parliament on 15th May and, unless there is unforeseen delay, will take effect on 24th June 2024.

Elmhurst’s Managing Director, Stuart Fairlie, comments:

“This is the end of a long journey for Elmhurst, and the industry, and we are delighted with the outcome. EPCs are one output of an energy assessment that includes data that is incredibly valuable for building owners and occupiers. After a two year hiatus we can once again provide our social landlord customers with the information and data to drive their energy efficiency strategies, ensuring that their properties remain at the forefront of energy efficiency thereby reducing fuel poverty, reducing climate emissions and improving fuel security. We are also thankful for the patience of all our social landlords and asset management companies whose energy efficiency aspirations needed to be put on hold whilst the legislation was being amended.”

In our meeting with government, it was made clear that whilst the legislation permits the sharing of data, nothing can be shared until rules and controls have been agreed with the industry and published in The Scheme Operating Rules. Even when implemented there will be no obligation on assessors or schemes to share data. Elmhurst will be contacting members and customers to explain the implications of this important change as soon as they are known.

Want to know more?

If you wish to know more about EPC data and how it can create insight and knowledge, then please do not hesitate to contact us.

The Elmhurst Almanac:

Using current EPCs to drive net zero ‘is like using scissors to cut grass’

Energy Performance Certificates (EPCs) must change to help drive policies for cutting carbon emissions.

Proposals for a ‘New EPC’ come from Elmhurst’s latest publication, ‘The Elmhurst Almanac 2024 – Driving progress during political change,’ launched on Tuesday 5 March.

It also urges government not to let a 2024 general election become a scapegoat for stunted progress in EPC reform.

“Put simply, EPCs are currently being used to drive policies for cutting carbon emissions – and they are not up to the task. It is like using scissors to cut grass,” said Stuart Fairlie, Managing Director of Elmhurst Energy.

“The current EPC was designed as a cost metric to simply show how cheap or expensive a home is to heat. Instead, they should be one of the most powerful tools we have to improve the energy efficiency of our homes and buildings so that they are carbon net zero-ready and can support decarbonisation of the grid.”

“EPCs now need to give much more information on the energy cost,

energy use and carbon emissions of a home or building. To make them easier to understand, the format should change to something similar to food labelling, and to increase their validity, they should be renewed every three years – or every time there is a change to a building that impacts its energy performance.”

At Elmhurst’s National Conference, on 27 February, Department for Levelling Up, Housing and Communities (DLUHC) head of the energy performance of buildings regulations, Keeran Jugdoyal, spoke about EPC reform progress earmarked for the coming months.

He said: “We know EPCs are buckling under the weight of what they are being used for. The system can’t stand up to this. But the value of EPCs is only increasing from a homeowner’s point of view – people are wanting to improve energy efficiency.”

The Almanac delivers 10 vital policy and regulatory recommendations to government for putting energy efficiency policy relating to UK homes and buildings back on track.

These include:

1. Use the ‘Golden Triangle’ of information in EPCs

EPCs should now show the ‘three Cs’: energy consumption, energy cost, and carbon emissions. They should also use a ‘Golden Triangle’ of information:

Asset rating: the predicted energy cost and consumption of the building, based upon nominal or average occupancy patterns.

Occupancy rating: the predicted energy consumption of the building, based on the people using it.

Energy consumption: what energy the building uses to run, ideally based on data from smart meters.

2. Launch the ‘New EPC’ alongside the Home Energy Model and Future Homes Standard

Consultations have now closed on the new Future Homes and Buildings Standards, and the Home Energy Model (HEM) – the latter which will be used to demonstrate that a home complies with legal energy efficiency performance targets.

Elmhurst says the most sensible solution would be to deliver a new EPC in 2025 to coincide with the Home Energy Model and Future Homes Standard. This means the long-awaited EPC consultation, earmarked in the government’s 2020 EPC Action plan, should be launched in the coming months.

3. Rebalance tax applied to fuel

Currently, any low-carbon heating solution running on electricity, such as a heat pump, is more expensive than running a traditional gas boiler. This means they won’t be recommended on the current EPC.

To change this, we must switch the ‘green levy’ in energy bills so it applies to gas rather than electricity supply. Price ceilings and floors should be applied to ensure that what is right for the environment is also right for the consumer.

4. Put minimum energy efficiency targets back in place

The government must take a deep breath and reinstate energy efficiency targets for the private rented sector. All non-domestic tenancies should be required to meet EPC C by 1 April 2027. EPC B

should apply to all privately rented non-domestic properties by 1 April 2030.

For private rented sector homes, the government should adjust the timeline previously proposed for all domestic private rented sector properties to reach EPC C for new and renewed tenancies by 2025, and all tenancies by 2028. Instead, new and renewed tenancies should reach EPC C by 2028, with a later date decided for all existing tenancies.

5. Launch a retrofit advice hub

A retrofit guidance hub located on GOV.UK would deliver much-needed consumer information on retrofit and energy efficiency improvements – including the best order to complete them and how they might work alongside planned property refurbishments.

It should support decisions around green finance and appropriate renewable technologies, such as heat pumps and solar panels, plus options for insulation, ventilation and heat recovery. The hub should also signpost to registered professionals so homeowners can locate properly accredited and trained people.

Improving Your Home

Funding Options for Energy Improvements

There are a number of funding options currently available to homeowners and tenants to support them in making their homes more energy efficient.

The majority of funding schemes available are targeted at homeowners or tenants in fuel poverty and non-energy efficient housing. Each scheme has its own specific set of eligibility requirements and there is no guarantee that funds will be awarded following an application.

In this article, we’ve provided a rundown of the various schemes that homeowners and/or tenants can benefit from. This list is not absolute; it is always advised to check with a local authority or housing provider to see if there are any further local or regional funding opportunities that can be taken advantage of.

The Social Housing Decarbonisation Fund (SHDF)

The Social Housing Decarbonisation Fund (SHDF) provides support to social housing landlords across England with an EPC rating of D or below. Social landlords can apply for the funding and, if awarded, can use the funds to target improvements in their housing stock.

On 18th March, the government announced details of the 42 councils, housing associations, registered providers of social housing, and charities across England who have been offered a share of £75.5 million from Wave 2.2 of the SHDF - subject to grant funding being signed. Assuming it is signed, the funding should be spent within the following 12 months.

As a tenant, you may not be in the position to decide if your home will benefit from this funding. However, it is worth checking to see if your housing provider has been awarded any funding and how and where it is being spent.

For more information, please visit:

https://www.gov.uk/ government/publications/socialhousing-decarbonisation-fundwave-2

Energy Company Obligation 4 (ECO4)

Probably the highest profile scheme at this moment is ECO4. ECO4 is essentially where energy companies are obligated to use profits to fund energy efficiency improvements for homes where the occupants are either in fuel poverty or are already receiving some form of financial assistance. There is £4 billion available to be spent over four years, ending in March 2026.

Eligible homes, once assessed, can benefit from a number of improvements including insulation, glazing, heating and hot water. ECO4 is focused on numerous improvements per property. This can

be beneficial but may mean that the funds provided will not go as far as earlier iterations of ECO.

For more information, please visit:

https://www.gov.uk/ energy-company-obligation

Home Upgrade Grant (HUG)

The Home Upgrade Grant is available to homeowners in England who have poor performing homes and are off the mains gas grid. To be eligible, you must own and live in the relevant property, and it will need to have an EPC rating between D and G. It is also likely that your household income will need to be less than £31,000 per annum, although this can vary in certain postcode areas.

The money, awarded as a grant from local authorities, aims to provide energy efficiency upgrades and low carbon heating to the worst performing households. Other improvement options include insulation for walls, lofts and floors as well as heating.

For more information, please visit:

https://www.gov.uk/ apply-home-upgrade-grant

Great British Insulation Scheme (GBIS)

The aim of the GBIS scheme is to offer single measure insulation improvements and is targeted at properties with an existing EPC rating of D to G and a Council Tax banding of A to D in England or A to E in Scotland or Wales.

You can be either a homeowner, landlord or tenant. However, if you are a tenant you will need to check with your landlord first, as their permission is required before any work can take place.

There is a fund of £1 billion to be

spent over a 3-year period lasting until March 2026, with the aim of providing additional insulation to 300,000 homes. Each property will only be eligible for one measure each and the homeowner may have to contribute towards some of the cost.

For more information, please visit:

https://www.gov.uk/ apply-great-british-insulationscheme

Boiler Upgrade Scheme (BUS)

Finally, is a scheme that is focused on encouraging homeowners to switch from fossil fuel heating systems, such as gas or oil, to a heat pump. This scheme offers a grant of up to £7,500 towards the cost of and the installation of a heat pump. This amount was recently increased from £5,000, which has resulted in a 57% rise in applications. As a result of this, a further £1.5 billion has been allocated to the BUS scheme, ensuring that even more homes can benefit.

For more information, please visit:

https://www.gov.uk/ apply-boiler-upgrade-scheme

Conclusions

We hope that this summary provides a good starting point for considering the current schemes on offer. It is important to do your own research into these schemes and any others that may be available in your area.

Minimum Energy Efficiency Standards: Scotland

The Scottish government recently consulted on their proposal for the heat in buildings bill.

The main purpose of the consultation was to seek feedback on their plan to prohibit polluting heating systems in buildings after 2045, for owner occupied homes to meet Minimum Energy Efficiency Standards by 2033 and for private landlords to meet the standards by 2028.

Whilst the UK has an overall target to reach net zero emissions by 2050, Scotland set their own target of 2045 through the Climate Change (Emissions Reduction Targets) (Scotland) Act 2019. This means that Scotland is aiming to achieve net zero emissions five years ahead of the rest of the UK. The proposed Heat in Buildings Bill aligns with this ambitious target by addressing one of the significant contributors to carbon emissions: heating systems in buildings.

By prohibiting polluting heating systems and mandating the minimum standards for both owner-occupied homes and private rental properties, the Scottish government is taking proactive steps to reduce carbon emissions from the built environment.

What does prohibiting polluting heating systems mean?

Prohibiting polluting heating systems after 2045 essentially means that the Scottish government plans to ban the installation and use of heating systems that rely on fossil fuels or emit high levels of greenhouse gases after this date.

2

What are Minimum Energy Efficiency Standards?

The Minimum Energy Efficiency Standards are a set of rules to help our buildings achieve a good standard of energy efficiency, meaning that heat is retained, and less energy is used. By installing energy efficient improvements such as insulating walls and roofs, emissions will be reduced, occupiers will save on their energy bills and people will be moved away from fuel poverty.

In England and Wales, the minimum standards only applies to private rented properties. The basic criterion for a domestic property is that it must reach at least an E band on an Energy Performance Certificate (EPC) to be legally let. 1

What is Scotland proposing for Minimum Energy Efficiency Standards?

The Scottish government is proposing that the owner of a domestic property can install a straightforward list of improvement measures to achieve the standards. The suggested list includes:

• 270 mm loft insulation

• Cavity wall insulation (CWI)

• Suspended floor insulation

• Draught-proofing

• Heating controls

• 80 mm hot water cylinder insulation

It is believed that these measures will have the most impact for the lowest amount of disruption and cost. The approach suggests that it would be possible for a home to meet a good efficiency standard by installing as many of these measures as possible.

This approach does limit the type of properties that would need to meet the standard. For example, a property with solid walls and floors and no loft space may not be able to meet a good efficiency standard, therefore a large proportion of homes in Scotland would become exempt.

The consultation does propose an alternative method of using the EPC to demonstrate compliance which, in Elmhurst’s view, would be the preferred method. Using the EPC to

meet the minimum standard means achievable targets can be set and progress can be measured and reported on.

England and Wales are a good example of this, as the minimum standards were introduced in 2018 for private rented properties and was implemented in phases being based on property types. This standard is based on the EPCs energy efficiency rating which is a fair and balanced approach.

Are there any differences in how the standard will be applied to owner occupied homes and private rented homes?

The suggestion is that homes will be required to meet the standard by following the same method of installing energy efficient measures listed above. However, where an owner occupied home has installed a clean heating system (e.g. heat pump) by 2033, they will not be required to meet the standard as they have already contributed to reducing emissions.

As tenants do not have the power to improve the energy efficiency of their home, landlords would still be required to ensure their properties have met the standard (by 2028), even if they have installed a clean heating system.

The introduction of the minimum standards would be a significant step for Scotland in meeting their target to achieve net zero by 2045. It should be based on a fabric first approach, ideally using the Retrofit standard, as all homes would see the benefit of low/zero carbon heating if they are well insulated.

To demonstrate that the standards are being achieved, the EPC should be used as the tool to measure viability and the same consistent approach should be used across the UK.

New Better Buildings Consultant certification opens client doors for energy efficiency

Olivia Garran, founder of 3E Assessments, was one of the first Elmhurst members to obtain its new Better Buildings Consultant certification.

After hearing about the new scheme and its benefits at the Elmhurst National Conference, in February, Olivia decided to take the assessment and was among the first to pass the test.

Originally a business consultant, Olivia decided to make the switch to energy assessment in 2007, following the renovation of a house in Buckinghamshire. Now, she runs a company delivering energy efficiency assessments and EPCs, retrofit coordination and assessment, plus a range of other support across residential, commercial and public buildings.

We spoke to her about why she decided to get certified and how it has influenced her work as an energy assessor.

What first attracted you to gain the Better Buildings Consultant certification?

The title of the Better Building Consultant certification mirrored what I do as a consultant, so it’s nice to be able to have a name that sums it all up that customers can really understand.

I don’t just provide EPCs, I provide advice and guidance. It’s not just about ‘ticks in boxes’ - it is actually much more in depth and holistic than that, particularly with some of the larger clients that I’m working with. The Better Buildings Consultant title recognises that.

In what ways do you think the certification enhances your professional credibility or reputation?

Since obtaining the Better Buildings Consultant certification I’ve managed to go out to my clients and say ‘I’ve got this’. I’m finding it helps me demonstrate a range of skills across a wide spectrum of energy efficiency specialisms, alongside building knowledge.

I’m also finding that giving my client’s a better understanding of what I do has also given me more credibility.

It shows I’m not just a domestic or commercial energy assessor, but that I can provide more than just those labels would demonstrate.

Do you think having the badge has helped you in your work as an energy assessor?

I believe it will become something that my clients will want to promote to say, ‘we have a Better Buildings Consultant working with us on this project’.

While I am a retrofit coordinator and retrofit assessor, I’m now able to expand on it and add that I’m also a Better Buildings Consultant. This enables me to provide more information and demonstrate that my expertise covers a wider range of specialisms relating to energy efficiency in buildings.

Would you recommend the Better Buildings Consultant to other energy assessors?

I would recommend the Better Buildings Consultant badge to assessors that want to go the step further and help people through projects where you take it from design, to strategy, to implementation and evaluation.

It just adds another feather to your cap and helps demonstrate to clients that your knowledge runs deeper and is more extensive, enabling you to provide more insight and expertise.

The process of getting certified was simple, too. It was reassuring that it tested your existing knowledge, rather than being a whole new course.

Have you adjusted your fees since getting the badge?

I would definitely consider it. I think that with the Better Buildings Consultant I would look at doing a sort of more hourly daily rate rather than job by job.

How have you incorporated the Better Buildings Consultant certification in your marketing material?

I will be updating my website and marketing materials, and I will make sure my current clients know I have the additional skills so that I can push it through word of mouth, too.

How valuable has obtaining the Better Buildings Consultant certification been for your business overall?

It’s still early doors, but I think looking forward it gives me a bit more gravitas.

As an energy efficiency professional, it’s what I’d like to call myself rather than an energy assessor. It demonstrates I am somebody who has a breadth of knowledge about properties across the board.

Turning Complaints into Opportunities

Maintaining Standards in Energy Assessment

Accuracy and transparency are vital aspects of the energy assessment industry, underpinning the hard work that assessors and retrofit professionals complete daily.

However, home and building owners who are not regularly exposed to energy assessment may find the industry's processes and terminology unfamiliar.

Oftentimes, the questions and concerns that arise from home and building owners surrounding their Energy Performance Certificates (EPCs) boils down to the misunderstanding of what the EPC is, what it is not, and what the relevant assessment involves. These misunderstandings can usually be prevented or resolved through education, or by ensuring that processes are followed when and if dissatisfaction occurs.

Common Misunderstandings Surrounding the EPC

The EPC does not account for the condition of the property or how the occupant uses it

A common misconception surrounding the EPC is mistaking it for a Condition Report. In this scenario, it is worth assessors taking the time to educate individuals about the purpose of the EPC and assessments. Although the EPC evaluates

energy usage for heating, lighting, ventilation, and hot water, it does not take into account the condition of the property.

An important point about EPCs, of which homeowners and building owners may not be aware, is that they do not reflect individual fuel bills. EPCs are based on standard occupancy and make assumptions based on how this standard occupancy would use the specific property. If a homeowner desires more information on their individual energy use, the assessor can recommend an occupancy assessment to be conducted by a Retrofit professional.

The EPC rating is lower than expected

If a property receives a lower than expected EPC rating, it can result in dissatisfaction among homeowners and building owners. These situations are particularly prevalent where time and money have been spent to make improvements to a property, such as installing a new boiler. Comparing a property’s EPC rating with those of neighbouring properties or with its previous ratings can further increase any frustration.

It is easy to sympathise with these frustrations, as an EPC rating is important to property value, as well as for funding applications (where specific

ratings are required). However, the result of an EPC is almost always explainable. As EPCs are valid for 10 years, unless a new EPC is produced, some of the conventions that they are based on may have changed over time. For example, if an EPC stated, ‘very good’ for double glazing when produced 10 years ago, it would now state ‘good’, due to the introduction of triple glazing. Assessors should aim to manage expectations and provide accurate explanations regarding rating variations. It is also worth explaining that the EPC descriptions, such as ‘very poor’ or ‘good’, are not based on the assessor’s opinion, but are generated by approved software and based on the collected data.

Assessors are the experts in their field and can often prevent or squash their customers’ confusion and concerns by explaining the EPC, the EPC assessment and the EPC rating in more detail. Elmhurst provides a checklist for assessors to provide customers in the first instance, detailing further information on such factors. Elmhurst members can access these documents via the Marketing Toolbox section of Access Elmhurst.

Customer Complaints Process

In situations where customer complaints occur, assessors should handle them professionally and with an open mind. Most importantly, it is important to follow the complaints procedure in place.

It is the assessor’s responsibility to respond to a customer complaint in the first instance, ideally within good timescales (1-3 working days).

If mistakes were made, they should be rectified. Where an

assessor is unsure on how to answer customer concerns, the Elmhurst Technical Support teams can provide guidance. The assessor must also notify Elmhurst of the complaint, as well as maintain any records for accountability. Should a resolution not be possible between the complainant and assessor, Elmhurst can help to mediate to ensure the correct outcome is reached.

The complaints process at Elmhurst serves as a cornerstone for Elmhurst members, enabling prompt resolution and fostering transparency. Elmhurst aims to support assessors throughout the complaints process, by offering guidance, mediation and ensuring fair outcomes. By following the procedures in place, assessors can help to maintain the standards of excellence across the industry, as well as demonstrate their commitment to customer satisfaction.

Whilst it is never fun to receive a complaint, quite often the situation can be seen as an opportunity for growth, allowing assessors to elevate their standards and understand where homeowners and building owners may need further information in the future.

Assessors should not view the complaints process as simply a formality but as a vital component in safeguarding the reputation and integrity of the industry. It is through transparent communication and continuous improvement that assessors can uphold the standards of excellence that are vital for a sustainable and trusted energy assessment sector.

The opportunities presented by building performance measurement

For energy assessors, retrofit assessors and surveyors

As we push for net zero buildings, it becomes ever more important that we measure and understand how buildings actually perform in practice. After all, we’re looking to achieve net zero in practice and not just theory!

This increasing focus on how buildings perform in the real world presents a whole host of opportunities for energy assessors, retrofit assessors and surveyors. Tools and techniques exist today that allow us to more readily measure the true performance of buildings, rather than rely on estimates and calculations.

Elmhurst continually strives to develop new accompanying tools, training and competencies to ensure that assessments, measurements, testing and reporting meet the highest technical standards and are governed by a framework of clear operating rules and processes.

What is building performance measurement?

Building performance measurement is the process of checking that a building’s actual performance is in line with the otherwise assumed performance or design intent. Building performance is synonymous with the quality of construction and influences in-use energy efficiency, comfort and usability. It typically involves measurement of fabric thermal performance and airtightness, heating and ventilation systems, energy use, overheating and householder experience.

What aspects of building performance can you measure exactly?

Tests range from measuring aspects of building fabric performance through to measuring and checking the efficacy of building services. Perhaps the most widely used measurement today is airtightness; this has been required for new build homes since 2007 and is increasingly used on retrofit projects under PAS 2035.

Methods also exist for measuring whole building heat loss rate or Heat Transfer Coefficient (HTC) - this offers great insight into the overall thermal efficiency of a building and how it compares to the original design intent. It is also possible to measure heat loss at an individual element level, assessing the in-situ U-values of floors, walls, ceilings and windows.

All these metrics are essential inputs for modelling tools as well as Dynamic Simulation Models. So, by measuring airtightness, U values and the HTC of a building, we can inform and update our energy models and understand how our buildings are actually performing; much in the same way that we already consider air tightness for as built EPCs on new build homes.

What is building performance evaluation?

Building Performance evaluation is the process of pulling together a range of building performance measurements and other insights to develop a deeper understanding of a particular building. As well as measurement of HTC, airtightness and U-values, other qualitative assessments may include Post Occupancy Evaluation surveys with occupants and thermal imaging of particular sections of a building. When combined and overlaid, such insights can help determine whether a building’s under performance is rooted in issues with the physical building and how it’s constructed, the set up and performance of the building services or if the issues are as a result of occupancy behaviours.

Elmhurst’s Measured Energy Performance service can determine the under or over performance of a dwelling. HTC measurement combined with airtightness testing can enlighten whether performance is fabric or infiltration related. In-situ U-value measurements and tools such as thermography can then also help to more accurately diagnose issues at an individual building element level.

Why should an Energy Assessor or Retrofit Assessor consider investing in the ability to carry out measurements?

The impending ability to input a measured airtightness result directly into an EPC under RdSAP 10 is a perfect example of how the world of building performance measurement services is set to converge with more traditional building energy assessments and property surveys.

Elmhurst members are in the ideal position to capitalise on their expertise and customer network by adding measurement related services into their existing offering. This provides an additional revenue stream, as well as added value and insight for clients.

Inexpensive and non-invasive tools and techniques are being developed by companies, such as Build Test Solutions, allowing for scalable and competitive adoption. Being a member of the respective competency scheme ensures clients are confident that practitioners have the relevant skills and understanding, improving industry image and confidence.

What policy changes are set to influence the call for measurement related services?

The future is bright, the future is measurement! Recent and impending consultations call out the desire for in-situ measurements to advance our understanding of our buildings.

The Future Homes Standard consultation proposed testing real world energy performance against modelled performance for new build homes from 2026.

There is also consideration for ECO4 to introduce a ‘pay for performance’ mechanism that will allow measured HTCs to be used to determine the

uplift awarded on ECO backed projects. We also expect to see a greater call for measurement and evaluations under PAS 2035 as well as via other Government backed schemes.

Some key developments to keep an eye out for include:

• The launch of Elmhurst’s competency scheme for measured HTC, called Measured Energy Performance on the 29th May.

• The introduction of RdSAP 10, which includes the ability to input measured airtightness - anticipated Summer 2024.

• DESNZ consultation, including ECO4 & GBIS Pay for Performance.

• FHS/HEM response on adopting HTC in situ measurement for new build homes from 2026.

Women in Energy Efficiency Fostering Community

and Overcoming Challenges

In the ever-evolving landscape of energy efficiency, the contribution of women is not only pivotal but also gaining significant recognition.

The Women in Energy Efficiency Facebook Group, supported by Elmhurst, has become a vital network for those navigating the energy assessment industry.

For this article, we have gathered feedback and insights from group members, asking them to share their experiences, challenges, and ideas for improvement.

A network of support and learning

The Women in Energy Efficiency Facebook group provides a platform for communication and community for women working in the industry. The group is not just for asking questions or finding solutions, but also for improving collective knowledge and sharing expertise and experiences with other assessors and retrofit professionals. Better yet, the group offers a judgment-free space for learning and exchange; vital for those who are self-employed and do not have colleagues to lean on.

Amy George, AG Energy Assessments, comments

“I love this group! There is no judgement, just support and it is great not to feel [like] you’re on your own as a woman in what is still a very male dominated industry”.

The practical benefits of the group are also helpful for those new to the industry to find their way. The group serves as a real-time resource for troubleshooting and advice, often outpacing other support channels available.

Nikki Surtees comments, “For someone like myself, [who] is fairly new to the industry, the Facebook group has been invaluable. It has benefitted me to read about other people’s challenging assessments and how they have overcome them.”

Challenges in a maledominated field

Despite progress, challenges still exist for women working in the energy assessment industry. This often comes down to the common belief and expectation that the work should be carried out by men.

As Clare Cartwright comments, “discrimination does not necessarily come from the men. There [are] still women who expect a man to carry out the tasks. I feel we need to broaden the industry as a whole, to normalise women in it…”.

Interestingly, there are situations where it may be an advantage to be a woman working in the industry. As Clare continues, “certain religions would prefer a woman in the home carrying out surveys etc, so the women of the house did not need to cover up… There was no judgement on my capabilities, and they preferred to ask a woman to carry out the survey as they felt more comfortable with me entering their home.”

A friendly and respectful environment

The Women in Energy Efficiency Facebook Group fosters an environment that is built on inclusivity and mutual respect. The supportive nature of the group helps industry beginners but also fosters a culture of kindness and helpfulness.

Kerensa Beckford, Beckford Property Services, comments, “I find this group very friendly. There are no daft questions… This community is very helpful, friendly and supportive. We all have to start somewhere!”

One assessor, initialled L.L, reflects on how the Facebook group initially started, commenting, “[prior to] this group, we had an online meeting… I suggested the idea of perhaps a group for women to support each other in our industry not expecting it to be taken seriously or even discussed, let alone resourced and delivered. So, thank you Elmhurst for not just paying lip service to women and ticking the box but actually listening and acting.”

Looking forward: Ideas

for growth and improvement

Elmhurst members are never shy about sharing their innovative ideas and improvement suggestions, including a potential WhatsApp Group and shadowing opportunities, as well as the call for greater industry inclusivity.

Nikki Surtees comments, “I believe more support is required for assessors new to the industry. Possibly in the form of a WhatsApp group or similar.”

Hazel Smith, Level 4 Energy Services, comments, “shadowing is a great idea, I wouldn't mind anyone coming round with me on non domestic… Working alone is really tough… [you can] come across so many weird and wonderful things that are not in the manual or you've never seen before, it can be bewildering.”

Clare Cartwright comments, “[we should] advertise across the genders, religions, cultures and then broaden the number of people in the industry. That will change things”.

Market Data

At Elmhurst, we collect and analyse data from sources to help us make better business decisions.

Turning this data into a digestible form takes time and requires a detailed understanding of context. In each edition of Energy Matters, we provide you with a snapshot of this data, with a brief commentary, which we hope you find of interest and can help you prepare for the future.

COVID-19 had a major impact on the construction, housing, and energy assessment markets, which is reflected in each of the charts. Some of the data related to new build homes within the devolved authorities has not been updated since December 2020 and estimates have been used.

Existing Dwellings

Existing Dwellings Volume of EPC lodgements and residential house sales on a rolling 12-month basis (by quarter).

Commentary

For the past five years, annual house sales have consistently hovered around 1.19 million.

The market experienced a significant downturn in March 2020 due to the COVID-19 pandemic but rebounded by July and has seen significant growth since. Sales peaked in the 12 months leading up to September 2021, reaching 1.55 million - a 17% increase over the previous high in March 2016 and 30% above the average. However, in the last 12 months up to September, sales volumes have started to decline, now standing at 1 million.

The volume of EPCs peaked in the 12 months to May 2014, driven in a large part by the Energy Company Obligation (ECO) scheme. This fell back sharply to a low of 1.2 million in March 2018. Two years of recovery peaked again in February 2020 with year-onyear growth of 11%, largely due to Minimum Energy Efficiency Standards (MEES) in the private rental sector. Since March 2020 (1.63 million), the volumes have dropped significantly but are now back on a level above pre-covid times of 1.68 million. There are many other reasons for an EPC to be completed, such as those for social housing as well as ECO4. The Local Authority Delivery Scheme and work funded by the Social Housing Decarbonisation Fund are likely to boost demand. Government initiatives, such as MEES should also continue to drive up the demand for EPCs. Typically, an increase in EPCs (represented by the blue line) suggests a corresponding rise in house sales. However, the graph indicates that this is not currently the case, suggesting that factors other than house sales are driving the demand for EPCs.

New Build / On Construction

New Build / On Construction Volume of residential house starts and completions on a rolling 12-month basis (by quarter).

Data for Scotland and Wales is estimated since December 2020. Volume of On Construction (new build residential) EPCs in the UK issued on a rolling 12-month basis.

Commentary

Following COVID-19, housing starts initially recovered rapidly, peaking at 217,000 in June 2021. However, they subsequently fell by 6% to 203,000 in March 2021. Since June 2023, there has been a consistent downward trend in housing starts, which currently stand at 178,000. Meanwhile, the volume of EPCs over the past twelve months has reached 276,000, up 12% from a low of 246,000. Although volumes peaked at 302,000 in February 2020, they are currently 9% below this peak.

Non-Domestic

Non-Domestic/Commercial buildings Nonresidential (commercial) property sales in the UK on a 12-month rolling basis. Volume of commercial property EPCs in the UK on a rolling 12-month basis.

Commentary

Commercial sales have shown a strong recovery, now standing 21% above the January 2021 lows and only 8% below the peak of October 2017. While EPCs are issued for various reasons beyond property sales, their issuance has surged, now 91% higher than the low in March 2021. The market has rebounded impressively, as indicated by the blue line's robust upward trend in Non-Domestic EPCs, despite a recent slight decline since October 2023. Sales of non-domestic properties, represented by the red line, have slightly decreased and recently stabilised

1. Level 1 Airtightness and Background Ventilation Assessment Training

Demand for airtightness tests is rising!

There are two big industry drivers for the increase in demand for Level 1 Airtightness training. Firstly, an update to build regulations in England, Wales and Scotland has led to the implementation of mandatory air testing in new build homes. With Government aiming to build at least 300,000 new homes every year, this is an exciting prospect.

Secondly, we now have confirmation that RdSAP 10 will accept airtightness test results, allowing for more accurate assessments of buildings and the current heat loss via air leakage. The result could also have a positive impact on the RdSAP Energy Performance Certificate (EPC) rating.

This qualification will be a sought after service by landlords looking for a cost-effective way to get meet the Minimum

3. Old and Traditional Buildings

Following the adoption of PAS 2035 (2023), all retrofit professionals will need to have an Older and Traditional Buildings
