Commercial EV Charging — Part of Your Energy Strategy
KMM installs EV chargepoints — but rarely as a standalone service. The right approach for most commercial clients is to scope EV charging as part of the on-site solar + battery + tariff strategy, because that's where the economics actually work. Pair charging with solar; use surplus generation; benefit from the Workplace Charging Scheme grant where eligible.
⚖ For commercial fleets transitioning to EV, workplace charging programmes, and domestic clients pairing EV charging with solar.
Should EV chargepoints be installed at the same time as solar?
Short answer. Yes — almost always. EV charging from the grid at standard tariffs is expensive; EV charging from on-site solar surplus is close to free. The two systems should be designed together, sized together, and (for fleet) paired with the right tariff and battery integration. Dealerships are the clearest case for designing both together; see solar for car dealerships.

Workplace Charging Scheme: what it pays in 2026-27
The government's Workplace Charging Scheme has been extended for a final year, to 31 March 2027. It covers up to 75% of the cost of eligible chargepoints, including VAT, capped at £500 per socket for installations completed on or after 1 April 2026, and up to 40 sockets per applicant across all your sites. The site needs dedicated off-street parking, and you need to own it or have the landlord's consent. The grant counts towards the £315,000 limit on minimal financial assistance over three financial years. Because the scheme closes in March 2027, installs planned for next year should be booked with that date in mind. Last verified: 18 October 2026.
Designing commercial EV charging with solar
Most workplace and fleet charging happens while vehicles are parked during the day, which is when a solar array is generating. Designing the two together lets the chargers use midday generation directly, and dynamic load balancing keeps the combined demand inside your supply capacity. Where vehicles charge in the late afternoon, a battery can hold surplus solar for later. Our commercial solar panels and battery storage pages cover the other two pieces.
Grid capacity and the DNO
Chargers add load, and a site's existing supply sets the limit. We check the supply capacity before specifying chargers, and where solar or a battery is part of the project, the whole site usually goes to the DNO in one G99 application. Our grid connection consultancy and G99 application guide explain the process. Car dealerships are the clearest case for planning all three together; see solar for car dealerships.
