Off-peak rate, peak rate and standing charge, all side-by-side.
Pick your tariff and your new supplier handles the switch — no interruption to supply.
An EV tariff is an electricity plan built around off-peak charging. You get a very low rate for a set window overnight — often around 7p per kWh — in exchange for a slightly higher daytime rate.
They rely on a smart meter recording your usage every half hour, so your supplier can bill different rates at different times of day.
The saving comes from the gap between off-peak and standard rates. These are typical figures for a car doing 8,000 miles a year:
| Charging method | Approx cost per kWh | Annual charging cost |
|---|---|---|
| Public rapid charger | 70p – 85p | £1,600 – £2,000 |
| Standard home tariff | 24p – 27p | £550 – £620 |
| Off-peak EV tariff | 7p – 10p | £160 – £230 |
The headline off-peak rate isn't the whole story. Look at these three things:
Some EV tariffs carry a higher daily standing charge that eats into your savings.
If you can't shift much usage overnight, a high daytime rate can cancel out the benefit.
Fixed EV tariffs may charge to leave early — worth knowing if rates move.
For anyone charging at home regularly, almost always. The savings come from three directions.
At around 8p per kWh, most EVs cost roughly 2-3p per mile to run — a fraction of petrol or diesel.
Running appliances overnight on the same cheap rate adds further savings beyond the car.
If you have solar and a battery, some EV tariffs also pay strong export rates for what you send back.
Every household is different. These are the variables that matter most:
A typical EV driver switching from a standard tariff to an off-peak EV tariff saves £350-£450 a year on charging alone.

They suit most EV owners, but they aren't right for absolutely everyone.
Switching takes minutes and there's no interruption to your electricity supply.
Confirm you have a working smart meter sending half-hourly readings.
Weigh off-peak rate, peak rate and standing charge against your actual usage.
Sign up with your chosen supplier — most applications take under ten minutes.
The changeover usually takes around five working days.
Configure your charger or supplier app to charge inside the cheap window.
A few conditions determine whether you'll get the full benefit:
Most suppliers require proof of an EV or a home charger. However, some general time-of-use tariffs offer cheaper overnight rates to any household with a smart meter, which can suit homes with batteries or storage heaters.
If you generate your own power, the right EV tariff turns your home into a small energy trading operation.
