EV Tariffs October 2026: Octopus, EDF and British Gas Off-Peak Rates

Home EV tariffs have shifted again this October. Intelligent Octopus Go now charges 7.6p per kWh off-peak, EDF GoElectric holds the lowest rate of the major tariffs at 6.66p, and British Gas EV Power charges 9.5p. All three are far below the 26.32p per kWh price cap rate, so the tariff you choose matters more than ever when you are charging 60kWh or more a week.

Wholesale prices have been unsettled this year, which is why the question of when to lock in a rate keeps coming up. We have set out the three big off-peak EV tariffs, the cost of a typical charge and the trade-offs to weigh before winter.

What are the main EV tariff rates this October?

Tariff	Off-peak rate	Off-peak window
EDF GoElectric	6.66p per kWh	11pm to 6am (7 hours)
Intelligent Octopus Go	7.6p per kWh	11:30pm to 5:30am (6 hours)
British Gas EV Power	9.5p per kWh	Midnight to 5am (5 hours)

Sources: EDF GoElectric, Intelligent Octopus Go and British Gas EV Power. Some trackers list British Gas EV Power at 9p per kWh, so confirm the current figure with British Gas. Check each supplier’s own page before switching, as rates differ by region and change on notice. EDF’s EV tariff page lists its current deals.

Intelligent Octopus Go: cheaper from 1 October

Intelligent Octopus Go’s off-peak rate is 7.6p per kWh, compared with 8p per kWh before 1 October 2026 (energy-stats.uk). The standing charge is 54p a day (Best Chargers). Octopus decides when your car charges within the window, so you need a compatible car or charger. Our guide to Octopus Go versus Intelligent Octopus Go explains which suits you, and our smart charger round-up lists compatible hardware.

EDF GoElectric: lowest rate, longest window

EDF GoElectric offers 6.66p per kWh for seven hours, from 11pm to 6am, and needs no smart charger (Best Chargers). That makes it the simplest option if your car or charger cannot talk to a supplier. The catch is the same on every tariff of this kind: electricity outside the window costs far more, so shift the dishwasher and washing machine into the cheap hours too.

British Gas EV Power: highest rate, but easy to run

British Gas EV Power charges 9.5p per kWh from midnight to 5am, and the rate covers everything your home uses in that window, not only the car (Best Chargers). The window is the shortest of the three, which suits a car with a modest battery. A bigger battery can need more than five hours of charging.

What does a charge cost on each tariff?

Using a 60kWh top-up as a round example:

Tariff	Rate	Cost of 60kWh
EDF GoElectric	6.66p per kWh	£4.00
Intelligent Octopus Go	7.6p per kWh	£4.56
British Gas EV Power	9.5p per kWh	£5.70
Ofgem price cap, Direct Debit	26.32p per kWh	£15.79

The cap figure comes from Energy Made Easy, covering 1 October to 31 December 2026. Our report on the Ofgem price cap and home EV charging has the detail, and the 0% VAT cut on electricity applies to all of these rates.

The gap between the cheapest and dearest EV tariff is only about £1.70 on 60kWh. The gap to a standard tariff is nearly £12. If you are still on a standard rate, switching matters far more than choosing between these three.

Should you fix before winter?

Octopus brought exit fees back on some new fixed products in 2026, saying that when wholesale prices get very volatile it has to introduce them to keep fixed rates as low as possible (Money To The Masses). That changes the calculation. A fixed deal protects you from rises, but it can cost you to leave if rates fall.

Before you sign, check three things: the length of the fix, the exit fee and whether the off-peak rate itself is fixed or tied to the supplier’s variable pricing. Our full EV tariff comparison shows every option, and the home charging cost calculator lets you test your own mileage.

What this means for you

If you have a smart-compatible car and want the lowest running costs, compare Intelligent Octopus Go and EDF GoElectric first. EDF is cheaper per kWh and needs no smart hardware. Intelligent Octopus Go suits you if you value Octopus’s scheduling. If you charge only occasionally, British Gas EV Power’s shorter window is less of a handicap.

Check your supplier’s page for the rate in your region, read the exit terms and set your charge to start inside the cheap window. Remember that a rate only helps if you charge inside the window: a car plugged in at 7pm on arrival home will pay the peak price, which is 36.70p per kWh on Intelligent Octopus Go and 36.90p on British Gas EV Power. A timer in the car or charger app is a small habit that protects most of the saving, and it costs nothing to set up.
