EV charger grants and funding for UK businesses
Grant availability changes far more often than the engineering does. So this guide works the other way round: get the connection, the design and the tax treatment right, then claim whatever support is genuinely open when you apply.
Four checks before you commit
Start with the connection, not the grant
Available spare capacity at your incoming supply decides what you can install. Adding six 22 kW chargers is a 132 kW load — often more than the array on the same roof. Check capacity before any funding conversation, because a reinforcement quote can dwarf a grant.
Check current grant routes before you budget
UK support for workplace and fleet charging has changed repeatedly and eligibility varies by organisation type, tenure and installer. Confirm what is open on GOV.UK at the time you apply rather than relying on a figure quoted in a proposal — and use accredited installers, since most schemes require it.
Do not forget capital allowances
Where a scheme does not apply or has closed, qualifying charge-point and plant expenditure may still attract first-year or full-expensing treatment for UK companies. Your accountant should confirm the position for your entity before you commit.
Model landlord and tenant reality
Leasehold sites need landlord consent, and the split-incentive problem is real: whoever pays for the chargers rarely collects all the benefit. Sub-metering, a licence to alter and a simple revenue-share agreed early prevents the project stalling at legals.
We do not publish grant values here because they change. Confirm current schemes on GOV.UK and the tax position with your accountant — nothing on this page is financial or tax advice.
Why chargers and solar belong in the same project
Chargers turn exported units into used units
Most commercial arrays export a share of their generation for a modest Smart Export Guarantee rate. Daytime workplace charging soaks that up at the value of the grid unit you avoid buying, which is usually several times higher.
Load management costs less than reinforcement
Dynamic load balancing across chargers, and between chargers and the array, frequently avoids a DNO upgrade entirely. It is a software and switchgear decision made at design stage, not an afterthought.
Batteries make fleet charging predictable
Where a fleet returns and charges in a tight window, storage flattens the peak so charging does not collide with your site's own demand. Sizing depends on the depot pattern, so model it against real telematics data.
Visible, and easy to explain
Solar canopies over staff and customer parking are the one part of a decarbonisation plan people can see. For retail, hotels and leisure sites the dwell-time benefit is often worth more than the units sold.

FAQ
Are there still EV charger grants for UK businesses in 2026?
Support for workplace and fleet charging exists but has been repeatedly revised, with eligibility depending on organisation type, site tenure and using an accredited installer. Check the current position on GOV.UK before budgeting, and treat any figure in a supplier proposal as needing verification.
How much does a workplace EV charging installation cost?
Hardware is rarely the problem. Groundworks, cable runs from the switchroom, distribution boards and any grid capacity work usually dominate the cost, which is why two identical charger specifications can quote very differently.
Do I need to upgrade my grid connection for EV chargers?
Not always. Load management, staggered charging schedules and on-site generation often keep you inside your existing capacity. A capacity assessment before design is the cheapest hour you will spend on the project.
Is it better to install solar and EV chargers together?
Usually yes. Shared cabling, shared roof or car park access, one design and one set of DNO paperwork reduce cost, and daytime charging lifts self-consumption — which is the single biggest driver of solar payback.
Can I charge staff or visitors for electricity?
Yes, and most sites do. Back-office platforms handle tariffs, RFID access and reporting. Confirm the tax and VAT treatment with your accountant, since it depends on who is charging and on what basis.
