EV charging for all
Encouraging EV adoption is a cornerstone of government plans to decarbonise, but such vehicles are only really feasible for those with driveways or access to limited public charge-points. But now, London’s Lambeth Council is building a blueprint for extending the electric revolution to underserved communities in London and beyond
By Frank Millard and Jack Roper
The London Borough of Lambeth is working with Connected Kerb, the EV charging specialist, in a first-of-its-kind project to demonstrate how affordable and accessible public EV charging infrastructure can be deployed to tackle EV inequality For countries worldwide to achieve carbon-neutral transport targets in the teeth of mounting climate turmoil, popular adoption of electric vehicles (EVs) will be imperative. That will depend on national charging infrastructures which are universally accessible, regardless of location or social context. Crucially, EV ownership must be rendered viable for dwellers in high-rise blocks or urban estates without off-street parking or access to overnight charging.
By 2030, the UK government hopes to see 14 million EVs on British roads. But 40% of UK households today have no garage or driveway and for every public-access on-street charger nationally, there are 34 EVs on the road. Consequently, these households own just 20%

“Unfortunately, a classic chicken-and-egg scenario is failing communities,” says Connected Kerb CEO, Chris Pateman-Jones. “Charge-point operators won’t build public infrastructure unless they see high EV adoption. But without reliable charging, why would anyone go electric?” It falls to proactive local and city councils to break this retrograde circle. In London, Lambeth Council has enlisted the services of Connected Kerb to install curbside chargers in areas of most need.
In 2018, Lambeth became the first London borough to declare a climate emergency and aims to reach net-zero carbon emissions across its estate, services and operations by 2030. Today, traffic causes 50% of its air pollution. Since about one-third of residents live on council-managed estates and less than half have off-road parking, a preponderant portion of Lambeth’s potential EV-driving populace would be entirely reliant on public charging infrastructure.

pavement with a visible, above-ground socket. The subterranean componentry will enable an array of hardware and software applications. The socket provides a 7kW fast-charge tailored to habitual charging at predictable daily times. Contactless payment via the Connected Kerb app based on a consistent tariff across sites will support fair and equitable access.
Charge-point broadband and 5G connectivity will be essential in future transport ecosystems driven by data science and artificial intelligence. Connected Kerb’s sunken smart city boxes already support connected environmental and parking management sensors and are equipped to provide data to tomorrow’s advanced mobility solutions. Its software platforms meanwhile optimize performance and energy-usage across its smart-node networks.
On the level…
Connected Kerb’s aspirations to democratize charge-point access dovetail with the “LevellingUp” agenda professed by UK government. “For those in society unable to park and charge at home, EVs remain an unattractive option,” says Pateman-Jones. “Failure to serve those communities risks creating a two-tier scenario where EVs are primarily adopted by the wealthy.” Nationally, Connected Kerb expects to install 30,000 on-street chargers in 2022 and 190,000 by 2030. “It’s critical to win the hearts and minds of all transport users,” he continues. “We’re pledging to educate every community in the UK on the benefits of EVs.”
Lambeth Council’s strategy is motivated by its early commitment to carbon-neutrality and the introduction of London’s Ultra Low Emission Zone (ULEZ). The current scheme is supported by 75% funding from the UK Office for Zero Emission Vehicles. “On highways, priority is driven by demand,” comments Lambeth Council’s head of communications, Lawrence Conway. “On estates, we have initially

UK roads per public look to provide chargers to charge-point estates of over 100 properties where we have a specific request,” he continues. Site surveys will determine the availability of adequate electrical capacity before the initial locations are confirmed. “Our ultimate strategy is to spread chargers as widely as possible and provide them within a five-minute walk of anywhere with no off-street parking.” Lambeth Council aims to install 200 chargers by 2022. The British government has committed to phase out new petrol and diesel car sales by 2030, by which time it expects the national EV fleet to grow to 14 million. Correspondingly, it predicts a need for 2.8 million public chargepoints nationwide and has recently announced proposals for a robust and expansive charging network. Considering the UK has just 30,000 public charge-points today, it is an enormous task. But councils are uniquely placed to support the transition which Connected Kerb’s businessmodel is designed to enable.
Mapping the revolution
A free online tool allows installers to cross-reference grid capability with future demand to accelerate the UK’s EV infrastructure roll-out
The Charge Project has created an online map identifying optimal locations for new EV infrastructure in the UK. Formed by SP Energy Networks and its partners EA Technology, PTV Group and Smarter Grid Solutions, the Charge Project aims to accelerate charge-point deployment across Cheshire, Merseyside, North Shropshire and north- and mid-Wales.
Its ConnectMore Interactive Map (CIM) is a free-to-use tool accessible via the SP Energy Networks website. It enables local councils, property developers and chargepoint operators to identify areas of high public demand and see where the electricity grid can most readily accommodate charging infrastructure. It establishes available capacity in minutes, whereas correspondence with distribution network operators can take days or weeks.
“The CIM allows installers to prioritize locations where existing network connection is plausible,” says SP Energy Networks Charge Project lead, Geoff Murphy. “In the past, both local authorities and businesses were put off investing in EV charging because establishing expected demand and installation feasibility was complex and time-consuming. The CIM could change that forever, quickly delivering the hard evidence needed to get charge projects off the ground.”
The CIM includes a predictive transport model based on PTV Group’s Visum software. This uses four potential EV uptake and charge-point roll-out scenarios and displays demand data for each in fiveyear increments from 2025 to 2050. It also shows where residential driveways will enable home-charging. The electricity network model, provided by EA Technology, will be updated every three to six months.
“Transport models are updated after a shelf-life of about three years,” Murphy says. “Plans to update or extend the CIM depend on its utilization and value. But potentially, it’s a game-changer for public charge-point installation.” Current example
“Our partnership with Lambeth Council is a prime example of how affordable and accessible charge-points can kick-start the EV revolution in council-owned housing estates,” says PatemanJones. “Our sustainable, long-life, easy-to-deploy on-street infrastructure allows us to reach communities others cannot.”
Other solutions typically last for five to seven years, but Connected Kerb believes its system can offer a 25-year lifespan. “It becomes an infrastructure proposition as opposed to a product sale,” explains Pateman-Jones. “Because we earn our money back over a longer period of time, we can reduce the cost of EV charging points to our consumers.”
Connected Kerb sees Lambeth as a blueprint for public EV infrastructure roll-out elsewhere. From East Sussex to Northumberland, it is already implementing its technology in councilled projects across the country. “In Kent, we’re installing chargers for non-urban parish councils,” says Pateman-Jones. “We can bring vital infrastructure to communities which would otherwise be left behind due to low footfall and limited grid coverage.
“The time for pledges is over,” he concludes. “We need every road user to fight the climate change battle together, in every corner of the globe. That’s why we are focused on deploying EV infrastructure that makes charging sustainable, affordable and inclusive. By working with councils, we can help them meet air quality and emissions targets, deliver infrastructure and ultimately enable the UK to reach net-zero.” ■
