Finding the best EV tariff UK 2026 is not about chasing the lowest headline night rate. A 7p per kWh off-peak window looks unbeatable on paper. However, the same tariff usually charges 3p to 4p more than a standard fixed deal between 5:30am and midnight. Furthermore, standing charges on dedicated EV tariffs now sit close to 60p a day. Consequently, the maths only works if you can shift enough of your charging, and your other appliances, into the cheap hours.
This guide breaks down three of the biggest names in the UK market: Octopus Go, OVO Charge Anytime and EDF GoElectric. In addition, it shows the exact annual cost for a driver covering 7,400 miles a year. It also covers the scenarios where an EV tariff actually loses to a plain fixed rate.
How we worked out the real running costs
To compare fairly, we applied one driver profile to every tariff. We also left public charging out of the totals at first. That way, the only variable is the home energy deal itself.
The driver profile we used
- 7,400 miles a year, close to the UK average of roughly 7,000 to 7,500
- Efficiency of 3.5 miles per kWh in a mid-size electric car
- 80% of charging at home, 20% on public rapid chargers
- 2,700 kWh of ordinary household electricity a year
- 500 kWh of appliances shifted into the off-peak window
- A smart meter, which every one of these tariffs requires
On those numbers, the car needs roughly 2,115 kWh a year. Meanwhile, home charging accounts for about 1,690 kWh of it. That leaves total metered consumption of 4,390 kWh once ordinary household use is added. All rates below are illustrative averages for autumn 2026, so always check live figures before switching.
Octopus Go, OVO Charge Anytime and EDF GoElectric compared
Octopus Go
Octopus Go remains the benchmark. In autumn 2026 it pairs a peak rate near 27.9p per kWh with an off-peak rate around 8.5p between 00:30 and 05:30. The standing charge sits at about 60.2p a day. There is no exit fee, and the tariff runs for 12 months.
The catch? Only five hours qualify. Therefore you need either a large drive battery or a car and charger that can schedule a full charge inside that window. For drivers who want more, our Octopus Intelligent Go review explains how the smart version stretches the cheap rate to six hours and adds extra slots at around 7p.
OVO Charge Anytime
OVO takes a different approach. The unit rate stays flat at roughly 25.4p per kWh, with a standing charge near 55.9p a day. Then the app credits 10p per kWh back on any EV charging it schedules, at any time of day.
As a result, the effective EV rate lands near 15.4p rather than 8.5p. However, you avoid the peak-rate penalty on everything else in the house. You will need a compatible smart charger or car, such as an Ohme, Zappi, Indra or Hypervolt unit. It is worth checking our guide to the best home EV chargers before you buy.
EDF GoElectric
EDF GoElectric mirrors the Octopus structure. It offers roughly 9.0p per kWh between 00:00 and 05:00, against a peak rate of about 28.5p. The standing charge is the highest of the three at around 61.5p a day.
In addition, EDF bundles a free home charger with some EV packages. That can offset the higher unit rates in year one. Do check the current terms, because bundle offers change frequently.
Annual cost breakdown for a 7,400-mile driver
| Tariff | Peak rate | Off-peak rate | Standing charge | Annual cost | vs standard fixed |
|---|---|---|---|---|---|
| Standard fixed rate | 24.9p | n/a | 53.0p | £1,287 | baseline |
| Octopus Go | 27.9p | 8.5p (00:30-05:30) | 60.2p | £1,020 | £267 saved |
| EDF GoElectric | 28.5p | 9.0p (00:00-05:00) | 61.5p | £1,049 | £238 saved |
| OVO Charge Anytime | 25.4p | 10p credit, anytime | 55.9p | £1,150 | £137 saved |
On this profile, Octopus Go wins. It beats EDF GoElectric by around £29 a year and OVO Charge Anytime by roughly £130. Nevertheless, the margins are far tighter than the headline rates suggest.
When a cheap EV tariff loses to a standard fixed rate
Here is the part most comparison articles skip. A cheap night rate is worthless if your household uses a lot of power in the day and very little overnight.
The home-worker trap
Picture a home worker with a heat pump. They use 6,000 kWh a year outside EV charging. They only charge 600 kWh at home, because most of their mileage happens on longer trips.
- Standard fixed rate: 6,600 kWh at 24.9p plus £193 standing charge = £1,837
- Octopus Go: 1,000 kWh shifted at 8.5p, 5,600 kWh at 27.9p, plus £220 standing charge = £1,867
- EDF GoElectric: £1,910
- OVO Charge Anytime: £1,820
Consequently, Octopus Go costs £30 more than a plain fixed rate. EDF GoElectric costs £74 more. Only OVO Charge Anytime stays ahead, and even then by just £16. Therefore, high daytime consumption can quietly cancel out the whole benefit of a cheap night window.
An EV tariff is a load-shifting product, not a discount. If you cannot shift load, you are simply paying a higher daytime rate for nothing.
Standing charges are the hidden cost
Standing charges have climbed sharply since 2021. On these EV tariffs they add £204 to £224 a year before you use a single kilowatt. On a standard fixed rate, the same figure is nearer £193.
That gap matters. A 7p per day difference is £26 a year, which wipes out a large slice of a modest saving. The Ofgem price cap sets the ceiling on these charges for default tariffs, but fixed EV deals sit outside it. Always compare the full annual figure, not just the unit rate.
If you also generate your own power with balcony solar panels, a high daytime rate hurts even more. On the other hand, self-generated daytime power makes a cheap night-only tariff far more attractive.
Public charging does not change the ranking
About 20% of those 7,400 miles will happen away from home. At roughly 79p per kWh on a 150kW rapid charger, that is around 423 kWh and £334 a year.
In addition, that cost is identical whichever home tariff you choose. Therefore it belongs in your motoring budget, not your tariff comparison. The Energy Saving Trust has a useful breakdown of charging costs by location.
How to switch without losing money
- Confirm your smart meter reports half-hourly readings
- Check the exit fee, usually £0 to £50 per fuel
- Note the length and timing of the off-peak window
- Make sure your charger or car supports scheduled charging
- Check whether the tariff requires proof of an EV or plug-in hybrid
- Budget for road tax, because EVs now pay VED at the standard rate, around £195 a year in 2026
You can confirm current vehicle tax bands on the GOV.UK vehicle tax tables. Switching energy supplier usually takes around five working days once your 14-day cooling-off period ends.
Verdict: which tariff should you pick?
- Octopus Go (or Intelligent Go): the best all-round pick if you charge at night and can shift 400 to 500 kWh of appliances into the cheap window.
- EDF GoElectric: a close second, and stronger if a free charger bundle applies in year one.
- OVO Charge Anytime: the safest option for low-mileage drivers and households with heavy daytime use, because there is no peak-rate penalty.
For the average 7,400-mile driver, Octopus Go saves the most at roughly £267 a year. However, if you work from home, run a heat pump, or charge mainly away from home, a standard fixed rate may genuinely beat it. Run your own annual kWh figures through each tariff before you commit.
So which side of the line do you fall on? Are you shifting load every night and banking the saving, or paying a premium peak rate for a cheap window you barely use?
