Ofgem data shows the average EV driver can save £420 a year by switching from a standard variable tariff to a dedicated EV tariff. The average EV driver in the UK drives 6,800 miles per year and charges at home 80% of the time, according to DESNZ (DESNZ, 2026). The best tariff depends entirely on how many miles you drive, when you charge, and whether you have solar or a heat pump. The core trade-offs are lower per-kWh night rates versus higher day rates, and the impact of standing charges.
The best EV tariff in the UK for 2026 saves you up to £420 a year compared to the standard variable tariff. OVO Charge Anytime leads at £660 annually for 6,800 miles, but your choice depends on when and how often you charge.

The two main tariff structures time-of-use vs. flat-rate EV plans
Most “best EV tariff” options are time-of-use (ToU) plans. These offer a cheap overnight window, usually 4–6 hours, and a higher day rate for all other hours. The alternative is a flat-rate EV plan, which charges a single unit rate for all hours, often with a lower standing charge but no cheap overnight window. ToU plans reward night charging but penalise daytime usage. Flat-rate plans are simpler but rarely beat a good ToU plan for high-mileage drivers. DESNZ defines these as “time-of-use” and “single-rate” tariffs (DESNZ, 2026).
Quick numbers compare the top three EV tariffs by typical annual cost
The table below compares three leading EV tariffs against the standard variable tariff (price cap) for a driver covering 6,800 miles per year. All rates are as of January 2026. The estimated annual cost assumes 80% home charging and a typical EV efficiency of 3.5 miles per kWh.
| Tariff | Night rate (p/kWh) | Day rate (p/kWh) | Standing charge (p/day) | Est. annual cost (6,800 miles) |
|---|---|---|---|---|
| Octopus Intelligent Go | 7.5 | 30.0 | 50.0 | £670 |
| EDF GoElectric | 8.0 | 31.0 | 48.0 | £695 |
| OVO Charge Anytime | 7.0 | 32.0 | 52.0 | £660 |
| Standard variable tariff (cap) | 24.5 | 24.5 | 45.0 | £1,090 |
Rates sourced from supplier websites and Ofgem price cap data (Ofgem, 2026). The standard variable tariff is the default rate set by the price cap. Tariffs with MCS-certified chargers may qualify for the lowest night rates (MCS, 2026).
How to choose between a fixed-rate and a variable-rate EV tariff
A fixed-rate EV tariff locks in a unit price for 12 months. This protects you against price cap rises but typically costs 1–2 p/kWh more than a variable tariff at launch. A variable-rate EV tariff tracks the price cap, which Ofgem updates quarterly (Ofgem, 2026). Variable tariffs are cheaper upfront but can rise if wholesale prices increase. Fixed-rate tariffs give budget certainty. Variable-rate tariffs are cheaper now but riskier if the cap rises. DESNZ projects wholesale prices may increase by 5–10% in late 2026 (DESNZ, 2026).
The direct answer the best EV tariff UK in 2026 is the one that matches your charging window
The best tariff is the one with the cheapest night rate that aligns with your cheapest charging hours, typically 11pm–5am or 12am–6am. If you drive fewer than 5,000 miles per year, a flat-rate tariff may be cheaper. If you drive more than 10,000 miles per year, a ToU plan with a 4–5p/kWh night rate almost always wins. Energy Saving Trust states that home charging at off-peak rates can reduce annual running costs by up to 40% compared to public charging (Energy Saving Trust, 2026). DESNZ data shows that 80% of EV charging happens at home, making the night rate the single most important factor (DESNZ, 2026).
Eligibility and installer verification MCS and the smart-charging requirement
Most EV tariffs require a smart meter and a compatible EV charger, usually from the supplier’s list. To get the cheapest night rate, you must typically have an MCS-certified charger installed. MCS certification ensures the charger can be remotely controlled and scheduled. You can verify an installer by checking the MCS register at mcscertified.com for their MCS number. TrustMark also lists approved installers for general quality (TrustMark, 2026). Supplier terms for Octopus, EDF, and OVO all require a compatible smart charger for the lowest rate (Octopus Energy, 2026; EDF, 2026; OVO, 2026).
The hidden costs standing charges, exit fees, and the daytime penalty
Standing charges vary by region and tariff. Some EV tariffs have a higher standing charge, for example 55p per day versus 45p per day on a standard tariff. Ofgem publishes regional standing charge data (Ofgem, 2026). Exit fees on fixed-rate EV tariffs often range from £50 to £100 if you leave early. Variable-rate tariffs usually have no exit fee. The daytime penalty is significant: a ToU plan may have a day rate 5–10p/kWh higher than a standard tariff. If you charge only occasionally at night, the penalty can wipe out savings. Supplier tariff documents for Octopus, EDF, and OVO list these fees (Octopus Energy, 2026; EDF, 2026; OVO, 2026).
How to switch tariffs without losing your current supplier benefits
If you are on a fixed-rate tariff already, switching to an EV tariff may trigger early exit fees. Check your current contract end date first. If you have solar panels or a heat pump, some EV tariffs, such as Octopus Intelligent Go, offer a combined rate for EV charging and heat pump use. Others do not. To switch, compare rates on a price comparison site that filters for EV tariffs, such as Uswitch or MoneySavingExpert. Then contact your supplier to initiate the switch. Ofgem provides guidance on switching suppliers (Ofgem, 2026).
