How much does it cost to charge a Tesla in the UK?

Work out your own costs with the EV Cost Comparison →

The short version: Teslas are very efficient, so charging at home is cheap: about £5.50–£6.90 per 100 miles at the standard capped rate, or around £1.40–£1.70 on an overnight EV tariff. Superchargers cost more and vary by site and time of day; nights are much cheaper than days.

We use Tesla's own UK figures for each Model 3 and Model Y, plus the current price cap and published EV tariff rates. To try your own mileage, use the EV Cost Comparison.

How we work it out

Tesla doesn't publish the usable battery size of its UK cars, but it does publish an official power consumption figure in kWh per 100 km for each version. That's the most reliable starting point. We convert it to kWh per mile (1 mile = 1.609 km), then multiply by the price.

Cost per 100 miles = kWh per mile × 100 × price per kWh.

Official figures come from the WLTP test. In real life, especially on cold winter motorway runs, you'll usually use more. See our guide to EV winter range.

Cost per 100 miles by model

The most efficient, the Model 3 Rear-Wheel Drive, costs about £5.51 per 100 miles at the price cap and £1.36 on a 6.5p tariff. The thirstiest, the Model Y Performance, is about £6.86 and £1.69.

Specs from tesla.com/en_gb, checked 24 October 2026. The 50p column is an example to show scale, not a quoted Supercharger price.

Charging at home

On a standard variable tariff in England, Scotland or Wales, your unit rate is capped: 26.32p per kWh on average (Direct Debit, 1 October to 31 December 2026), plus a 54.83p daily standing charge. There's no VAT on household electricity from 1 October 2026 to 31 March 2027. Your exact rate depends on your region.

On an EV tariff, nights are far cheaper. Any time-of-use tariff works with a Tesla, because you can schedule charging in the car. Smart tariffs that control charging for you need a compatible car or charger, so check the supplier's list for your model. Rates we checked today:

• E.ON Next Drive Smart: 6.5p per kWh, 00:00–06:00 (needs a compatible car or charger).
• EDF GoElectric: 6.66p per kWh, 23:00–06:00 (any EV).
• Intelligent Octopus Go: from 6.5p per kWh (checked 31 October 2026), 23:30–05:30 (compatible car or charger).
• E.ON Next Drive: 8.5p per kWh, 00:00–06:00 (any EV).
• British Gas EV Power: 9.5p per kWh, 00:00–05:00 (any EV).

Daytime rates on these tariffs are set by quote and can be above the cap. The full comparison is in Intelligent Octopus Go vs other UK EV tariffs.

Charging at a Supercharger

There's no single national price. Tesla's support page says prices vary by site and show in the Tesla app and the car. Every European site has peak and off-peak rates, and the price is locked in when you plug in.

In our sample of UK sites, Tesla owners paid roughly 21p–31p per kWh at night and about 47p–48p by day. Non-Tesla drivers without a membership paid more.

Source: sample of 6 UK Tesla-owned sites on tesla.com/en_GB/findus, 29 Oct 2026, about 09:30 UK time. Prices vary by site and time; check the Tesla app. The lowest figure, £0.21 off-peak, is for Tesla owners only. Congestion fee up to £0.50 per minute. A Supercharging Membership gives non-Tesla drivers the owner price.

• Congestion fees can apply at busy sites if you stay plugged in at 80% or above, after the first five minutes.
• Non-Tesla drivers can use many sites through the Tesla app. They usually pay more, unless they take out a Supercharging Membership, which gives them Tesla prices.

To compare, look up the price at your usual site in the app and use the formula above. At an example 50p per kWh, a Model 3 Rear-Wheel Drive costs about £10.46 per 100 miles. That still beats a 40 mpg petrol car at today's pump price (see EV cost per mile vs petrol), but it's several times the cost of charging at home overnight.

Prices with and without VAT

Petrol, diesel and public charging: VAT 20%. Home electricity in Great Britain: 0% VAT from 1 October 2026 to 31 March 2027 (normally 5%; Northern Ireland stays at 5%), so the price cap figure is the same with or without VAT (HMRC VAT Notice 701/19). Households always pay the VAT-inclusive price.
