Most drivers save £300–500 a year moving from the price cap to an overnight EV tariff. You'll need a smart meter.
Compare EV tariffsA 7 kW smart charger lets you schedule charging into the cheap window automatically. Typical installed price is £800–1,100.

Find cheaper chargersYour annual miles divided by your car's efficiency gives the energy that reaches the battery. We add charging losses to get what you actually pay for at the socket. That energy is split between home and public charging using your slider, and the home part is split again between the off-peak and peak rates of your tariff. Everything is then divided by twelve.
Cost per mile is the simplest way to compare options: an EV on a 7p tariff costs about 2p a mile, a public rapid charger about 25p a mile, and a 42 mpg petrol car about 15p a mile at £1.38 a litre.
A 60 kWh battery charged from empty needs about 66 kWh from the socket after losses. On the price cap (26.32p from 1 October 2026) that's around £17. On an 8p EV tariff it's about £5.
The lowest headline off-peak rates in September 2026 are EDF GoElectric (6.99p), Utility Warehouse (6.9p, with conditions), Intelligent Octopus Go (8p) and E.ON Next Drive Smart (8.5p). The right one depends on the length of the cheap window, the peak rate you'll pay for the rest of the house, and whether your car or charger is compatible. Use the comparison above with your own numbers.
Yes. Every time-of-use EV tariff needs a working smart meter so the supplier can bill the cheap hours separately. Most suppliers will fit one free when you switch.
For occasional long trips, yes. As a main way of charging it is roughly the same cost per mile as petrol. If you can't charge at home, look at workplace charging, lamp-post chargers (often 40–55p) and network subscriptions that lower the per-kWh price.
Tariff rates are taken from supplier websites and independent comparisons in September 2026 and rounded. Peak rates vary by region, so enter your own from your bill for an exact figure. Nothing here is financial advice.
