Best home energy tariffs for Tesla owners
We worked out what 8,000 miles a year in a Tesla Model Y costs on each of the main UK EV tariffs, which ones connect to a Tesla directly, and where Tesla's own electricity licence stands.
Quick answers
- On our sums, 8,000 miles a year in a Tesla Model Y RWD uses about 2,040 kWh, which costs £132.60 on a 6.5p/kWh tariff such as Intelligent Octopus Go or E.ON Next Drive Smart.
- The same 8,000 miles costs £536.93 at the October to December 2026 price cap rate of 26.32p/kWh, so moving to a 6.5p EV tariff saves about £404 a year in energy.
- Intelligent Octopus Go connects directly to a Tesla through the Octopus app, so the car itself is scheduled and no particular charger brand is needed; Octopus's 6.5p variable version went on sale on 29 October 2026.
- E.ON Next lists the Tesla Model 3, Model Y, Model S and Model X as supported cars for Next Drive Smart, which is fixed at 6.5p/kWh from midnight to 6am for 12 months with no exit fee.
- Fixed-window tariffs that work with any car, such as EDF GoElectric at 6.66p and British Gas EV Power at 9.5p, cost £135.86 and £193.80 a year for the same Model Y mileage.
- Relying on Tesla Superchargers at Zapmap's September 2026 average of 48p/kWh for Tesla drivers would cost £979.20 for 8,000 miles, more than seven times the 6.5p home figure.
- Ofgem granted Tesla Energy Ventures an electricity supply licence on 11 March 2026, but Tesla has not announced a UK household tariff.
The best home energy tariff for most Tesla owners is a 6.5p/kWh smart tariff, either Intelligent Octopus Go or E.ON Next Drive Smart, both of which connect to a Tesla directly. On our sums, that charges a Model Y for 8,000 miles a year for about £133, against £537 on the standard price cap.
A Tesla is one of the easiest cars to put on a smart EV tariff. Both of the cheapest tariff-only deals can talk to the car through its connected services, so you do not need a particular brand of wall charger. Below we compare the main UK EV tariffs on what they would cost a Model Y driver, which ones work with a Tesla, and where Tesla’s own electricity licence stands.
All rates below were checked on 1 November 2026 and include VAT at the current 0% rate on household electricity.
How much does each tariff cost a Tesla Model Y over 8,000 miles?
A Model Y RWD driven 8,000 miles a year costs between £126 and £194 to charge on an EV tariff, against £537 on the price cap.
Method: 8,000 miles × 255 Wh per mile (EV Database’s combined real-world figure for the Model Y RWD) = 2,040 kWh a year, × each tariff’s off-peak rate, assuming all charging falls in the cheap hours.
| Tariff | Off-peak rate | Cheap window | Connects to a Tesla directly? | 8,000 miles a year |
|---|---|---|---|---|
| EDF Pod Point Plug and Power | 6.18p | 11pm to 6am | No, sold with a Pod Point charger | £126.07 |
| Intelligent Octopus Go (variable) | 6.5p | 11:30pm to 5:30am | Yes | £132.60 |
| E.ON Next Drive Smart | 6.5p | Midnight to 6am | Yes | £132.60 |
| EDF GoElectric | 6.66p | 11pm to 6am | Not needed | £135.86 |
| Intelligent Octopus Go (12-month fix) | 7.9p | 11:30pm to 5:30am | Yes | £161.16 |
| Octopus Go (12-month fix) | 9.4p | 12:30am to 5:30am | Not needed | £191.76 |
| British Gas EV Power | 9.5p | Midnight to 5am | Not needed | £193.80 |
| OVO Charge Anytime (pay as you go) | 13.33p | Smart scheduled | Check OVO’s tool | £271.93 |
| Ofgem price cap | 26.32p | Any time | n/a | £536.93 |
| Tesla Supercharger average (Tesla drivers) | 48p | n/a | n/a | £979.20 |
| Public rapid average | 79p | n/a | n/a | £1,611.60 |
Our standard smart tariff input of 8p/kWh, used across our running cost guides, gives £163.20. Sources for each rate are listed at the foot of this page; the Supercharger and public rapid figures are Zapmap’s September 2026 averages.
These figures cover energy only. Standing charges come on top whichever tariff you choose, and some energy is lost as heat while charging, so the meter reading will be a little higher. In cold weather EV Database puts the Model Y RWD at 308 Wh per mile; if every mile were driven at that figure, 8,000 miles at 6.5p would cost about £160.
The headline is simple. The gap between the cheapest and dearest EV tariff here is about £68 a year. The gap between any EV tariff and the price cap is £343 or more. Being on an EV tariff matters far more than which one you pick. For full-charge and per-mile costs across every trim, see our guide to the cost to charge a Tesla.
Does Intelligent Octopus Go work with a Tesla?
Yes. Octopus lets you add a Tesla as a device in its app, and the tariff then schedules the car’s charging rather than a charger’s. Octopus’s Tesla setup guide sets out what is involved:
- You sign in with your Tesla account and tick the “Vehicle Information” and “Vehicle Charging Management” permissions.
- Most Teslas need a virtual key; pre-2021 Model S and Model X cars and leased cars can skip this step.
- You have seven days after switching to connect the car.
- Only one Tesla can be connected per account.
The variable Intelligent Octopus Go went on sale on 29 October 2026 at 6.5p off-peak, with no exit fee. The 12-month fixed version is 7.9p with a £50 exit fee. Octopus gives up to six hours of smart charging a day at the cheap rate, plus the whole home at that rate from 11:30pm to 5:30am. If you press “bump charge” to charge straight away, Octopus bills it at the day rate, which is 38.27p in the London region on the variable deal.
Octopus says on its tariff page that it cannot guarantee compatibility, because car makers’ systems change. Run its eligibility check before you switch. Our report on Intelligent Octopus Go’s move to 6.5p covers the rate change in detail.
Does E.ON Next Drive Smart work with a Tesla?
Yes. E.ON’s supported vehicles list includes the Model 3, Model Y, Model S and Model X, though E.ON notes it does not always list every variant or model year.
Next Drive Smart is fixed at 6.5p/kWh from midnight to 6am for 12 months, with no exit fee. The cheap rate covers the whole home, and boosts outside the smart schedule cost 34.322p/kWh. You need a smart meter with half-hourly consent, and E.ON supports only one EV per account.
The choice between E.ON and Octopus comes down to fixed against variable and to standing charges. In London, the Intelligent Octopus Go standing charge is 42.56p a day, or £155 a year; E.ON’s is 57.14p, or £209. That £53 difference is worth checking for your own region before you switch.
Which tariffs work with any Tesla and any charger?
Fixed-window tariffs need no connection to the car at all. You set the car or the charger to start inside the cheap hours, and every unit used in that window is billed at the low rate.
- EDF GoElectric: 6.66p from 11pm to 6am, seven cheap hours, the longest window here (EDF).
- Octopus Go: 9.4p from 12:30am to 5:30am on the 12-month fix that went on sale on 30 October 2026, with a £50 exit fee (Octopus product data).
- British Gas EV Power: 9.5p from midnight to 5am on all usage, and British Gas says it “works with any make of EV and home charger” (British Gas).
These suit owners who would rather not hand over control of the car, have more than one EV, or have had trouble keeping a car integration connected. Our guide to Octopus Go against Intelligent Octopus Go goes through that trade-off.
The one thing to get right is the schedule. A Tesla plugged in at 6pm with no schedule set will start charging at the day rate, which is around 38p/kWh on the Octopus tariffs in London. If a fifth of your 2,040 kWh landed at 38.27p instead of 6.5p, the year would cost £262.22 rather than £132.60.
Is a five or six-hour window long enough for a Tesla?
Yes, for most drivers. 8,000 miles a year in a Model Y RWD is about 39 kWh a week, or 5.6 kWh a night. A 7.4 kW home charger adds up to 44.4 kWh in six hours and 37 kWh in five.
EV Database quotes 9 hours 45 minutes for a full 0 to 100 per cent charge of the 60 kWh Model Y RWD at 7.4 kW, so only a nearly empty battery needs more than one night. British Gas’s five-hour window is the tightest, but even that covers a week’s typical driving in a single session.
What about Supercharging?
Home charging sets the bill, but most Tesla owners Supercharge on longer trips. If 90 per cent of your energy comes from home at 6.5p and 10 per cent from Superchargers at the 48p/kWh Tesla driver average, 8,000 miles in a Model Y RWD costs £217.26 a year.
Method: 2,040 kWh × 90% × 6.5p (£119.34) + 2,040 kWh × 10% × 48p (£97.92).
So a tenth of your charging on the road accounts for nearly half the energy bill. Our Tesla Supercharger prices guide covers how Supercharger pricing works.
Does Tesla have its own energy tariff in the UK?
Not yet. Ofgem granted Tesla Energy Ventures a licence to supply electricity to homes and businesses in Great Britain, effective from 11 March 2026. Ofgem’s announcement says nothing about a launch date, and Tesla has not announced UK tariff prices. Until it does, there is nothing to compare, and the tariffs above are the options for Tesla drivers.
If you have, or are considering, a Tesla Powerwall alongside the car, Best Chargers has a guide to using a Powerwall for EV charging.
Which tariff should a Tesla owner choose?
- You want the lowest rate with certainty: E.ON Next Drive Smart, 6.5p fixed for 12 months, no exit fee.
- You want the lowest rate and are happy with a variable price: Intelligent Octopus Go, 6.5p variable, no exit fee, and usually a lower standing charge.
- You are buying a charger anyway: EDF’s Pod Point Plug and Power bundle at 6.18p, though it is a two-year fix with exit fees.
- You prefer not to link the car to a supplier: EDF GoElectric at 6.66p, with seven cheap hours.
Whichever you choose, check the day rate and standing charge for your postcode, check any exit fee on your current deal, and set a charging schedule in the car.

Frequently asked questions
What is the best energy tariff for a Tesla in the UK?
For most Tesla owners with a driveway, Intelligent Octopus Go or E.ON Next Drive Smart is the best choice, both at 6.5p/kWh overnight and both able to connect to a Tesla directly. E.ON's rate is fixed for 12 months; Octopus's 6.5p version is variable. EDF's Pod Point bundle is cheaper at 6.18p, but it comes with a charger and a two-year contract.
Does Intelligent Octopus Go work with a Tesla?
Yes. Octopus lets you add a Tesla as a device in its app, signing in with your Tesla account and granting vehicle information and charging management permissions. Most Teslas also need a virtual key, only one Tesla can be connected per account, and Octopus says it cannot guarantee compatibility for every car.
How much does it cost to charge a Tesla Model Y for a year at home?
It costs about £133 to charge a Model Y RWD for 8,000 miles a year on a 6.5p/kWh tariff, on our sums. That uses EV Database's average of 255 Wh per mile, or 2,040 kWh a year. The same mileage costs about £537 on the 26.32p/kWh price cap rate.
Does Tesla have its own energy tariff in the UK?
No, not yet. Ofgem granted Tesla Energy Ventures a licence to supply electricity in Great Britain from 11 March 2026, but a licence is permission to trade rather than a product, and Tesla has not announced UK tariff prices or a launch date.
Do I need a smart charger for a Tesla on an EV tariff?
Not always. Intelligent Octopus Go and E.ON Next Drive Smart can control a supported Tesla directly through its connected services. Fixed-window tariffs such as EDF GoElectric, Octopus Go and British Gas EV Power need no smart link at all; you set the car to charge inside the cheap hours.
Is a six-hour off-peak window long enough for a Tesla?
Yes, for typical mileage. 8,000 miles a year is about 39 kWh a week in a Model Y RWD, and a 7.4 kW home charger can add up to 44.4 kWh in six hours. EV Database quotes 9 hours 45 minutes for a full 0 to 100 per cent charge of the 60 kWh battery at 7.4 kW, so only a near-empty battery needs more than one night.
