British Gas is the UK’s largest household energy supplier by customer count, and its dedicated EV tariff, EV Power, is an accessible option for existing British Gas customers who want to cut home charging costs. From 1 October 2026 it costs 9.5p/kWh from midnight to 5am, with 100% renewable electricity and prices fixed until March 2028.
It is no longer a price leader, though. The overnight rate trails the best EV tariffs, the day rate is among the highest we track, and leaving early costs £200 per fuel. This review gives you the full picture.
How British Gas EV Power works
EV Power is a whole-home time-of-use tariff. From midnight to 5am every day, everything your home uses is billed at 9.5p/kWh; British Gas describes this as 35 off-peak hours every week. Set your EV charger or car timer to charge within that window and the reduced rate applies automatically.
British Gas does not publish its day rate or standing charge without a quote. Based on its published regional tariff data, the day rate averages 36.90p/kWh (from about 35p to 39p depending on region) and the standing charge averages 54p a day. Rates are correct as of October 2026 and include 0% VAT, which applies to household electricity in Great Britain until 31 March 2027.
A smart electricity meter is required. If you don’t yet have one, British Gas will arrange installation free of charge.
Hive Power+ and Charge Power
British Gas’s best EV feature is not the tariff itself but Hive Power+. If you have a compatible Hive EV charger, Power+ takes 25% off all your EV home charging on any British Gas electricity tariff. British Gas says that combined with EV Power it is equivalent to 7.125p/kWh, and that a driver doing 9,000 miles a year could pay about £193 in total for home charging. On a time-of-use tariff, Power+ only charges your car during the off-peak window.
For homes with a home battery, British Gas’s Charge Power tariff offers half-price electricity from midnight to 5am instead, and British Gas recommends it over EV Power if you have both an EV charger and a battery.
Rates in context
| Metric | British Gas EV Power | Intelligent Octopus Go | E.ON Next Drive Smart | EDF GoElectric |
|---|---|---|---|---|
| Off-peak | 9.5p/kWh | 7.6p/kWh | 8.1p/kWh | 6.66p/kWh |
| Window | 00:00–05:00 | 23:30–05:30 plus smart slots | 00:00–06:00 plus smart slots | 23:00–06:00 |
| Peak (average) | 36.90p/kWh | 36.70p/kWh | 30.82p/kWh | 35.21p/kWh |
| Exit fee | £200 per fuel | £50 | None | £75 per fuel |
British Gas is beaten on the overnight rate by all three rivals, and E.ON Next Drive Smart’s average day rate is about 6p/kWh lower. The exit fee is also the highest in this comparison.
Who is British Gas EV Power best for?
The tariff suits existing British Gas customers who want to add EV charging savings with minimal friction. Switching within British Gas avoids the hassle of changing supplier, and British Gas’s customer service is well established.
It is strongest for Hive EV charger owners, because Hive Power+ brings the effective charging cost down to around 7.125p/kWh.
Who should look elsewhere?
If you are not already with British Gas, most drivers will do better elsewhere. Intelligent Octopus Go and E.ON Next Drive Smart both charge less overnight and add smart charging slots, and E.ON Next Drive Smart has a much lower day rate and no exit fee. EDF GoElectric has the lowest overnight rate of all at 6.66p/kWh.
Customer experience
British Gas’s customer support is extensive, with phone, live chat, and in-app options. The Hive app is polished and well maintained, with strong smart home integration. For customers who prioritise a familiar, full-featured app over specialist EV features, the experience is positive.
Our verdict on British Gas EV Power
British Gas EV Power is a competent but not outstanding option. It will save money compared with a standard variable tariff, it comes with renewable electricity and a long fix, and Hive Power+ is a genuine advantage for compatible households. But the 9.5p overnight rate, a high day rate and a £200 per fuel exit fee mean it only makes sense for existing British Gas customers, particularly Hive owners.
If you’re not already with British Gas, compare Intelligent Octopus Go and E.ON Next Drive Smart first.
