EV charging cost UK 2026: home vs public

Direct answer

What does it actually cost to charge an electric car in the UK?

There is no single answer, because UK electricity is sold to EV drivers at rates spanning roughly 7p to 92p per kWh depending on where and when you plug in. For a 60 kWh car that is a spread of £4.19 to £55.20 for one full charge. The three prices that matter are the overnight EV tariff rate at home, the standard domestic rate at home, and the pay-as-you-go rate on the public network.

At home, the standard rate under the Ofgem price cap for 1 July to 30 September 2026 is 26.11p per kWh (England, Scotland and Wales average, direct debit, including 5% VAT), alongside a 57.19p daily standing charge. Switch to a smart overnight EV tariff and the off-peak rate collapses: EDF’s GoElectric publishes 6.99p per kWh between 11pm and 6am, and Octopus advertises 8p per kWh on Intelligent Octopus Go between 11:30pm and 5:30am. OVO’s Charge Anytime add-on separately meters the car at a flat 14p per kWh whenever it charges. Rates vary by region on all of these.

On the public network the Zapmap Price Index put the weighted average pay-as-you-go price in July 2026 at 54p per kWh on 3–49 kW slow and fast chargers and 80p per kWh on 50 kW and above rapid and ultra-rapid units. Zapmap converts those to roughly 16p and 24p per mile for an average-efficiency EV. Individual networks in the rapid top ten ranged from 59p to 92p per kWh, with InstaVolt highest at 92p and Tesla cheapest at 63p in daytime hours.

The practical conclusion is that an EV is dramatically cheaper than petrol if you can charge at home overnight, roughly line-ball with petrol on slow public chargers, and more expensive than petrol on ultra-rapid units.

The VAT gap

Why public charging carries 20% VAT and home charging only 5%

Electricity supplied to a domestic property is a reduced-rate supply at 5% VAT. Electricity drawn from a public charge point is, in HMRC’s view, a standard-rated supply at 20% VAT — a position set out in VAT Notice 701/19 and restated in Revenue and Customs Brief 4 (2026), published on 12 May 2026, which says plainly that charging electric vehicles at public charge points remains standard rated.

That 15-point gap is not trivial. On an £48.00 ultra-rapid charge, £8.00 is VAT. If the same charge were reduced-rated it would cost £42.00 — a saving of £6.00 every time you fill up. Across 10,000 miles a year charged entirely on ultra-rapid units (about 2,941 kWh at 80p/kWh, or £2,353) the VAT element is roughly £392 a year, of which around £294 would disappear at the domestic rate.

The rule is being tested. In a First-tier Tribunal decision in March 2026, Charge My Street Limited succeeded in arguing that supplies at public charge points can fall within the de minimis provisions of the VAT Act 1994 — broadly, supplies to an identified person at identifiable premises not exceeding 1,000 kWh in a calendar month — and so qualify for the 5% rate. HMRC disagrees with the decision and has sought permission to appeal, and Brief 4 (2026) confirms that its published policy is unchanged in the meantime. Nothing has changed for drivers yet, but the outcome is worth watching if most of your charging is public.

The asymmetry matters most for the roughly one in three UK households without off-street parking. A driver who can only rely on public infrastructure pays both the higher unit price and the higher tax rate on it, which is why the home-versus-public decision, not the choice of car, is usually the biggest single variable in an EV’s running costs.

And insurance

Where charging costs meet insurance costs

Cheap electricity does not automatically mean a cheap car to run overall. Electric cars average around £650 a year to insure against roughly £600 for the market as a whole, driven mainly by higher list prices and Thatcham-measured repair costs — the detail is in our electric car insurance cost guide and benchmarked against every region in the UK car insurance cost index. Model choice moves it far more than fuel type does; the MG ZS EV, for example, sits well below the EV average.

Two charging-specific insurance points are worth checking on any policy. A home wallbox is usually covered as a fixture under buildings insurance rather than motor insurance, but not always — confirm it rather than assume it. And charging cables left in situ, plus public liability for a cable trailing across a pavement, are covered by some comprehensive EV policies as standard and excluded by others. Neither is expensive to add, but both are easy to miss at renewal.
