At the current Ofgem price cap of 27.69p/kWh (Q1 2026), charging a Tesla Model Y Long Range from 0–100% costs around £20.27. At a Supercharger the same top-up costs roughly £41. For most UK drivers who charge at home overnight, annual charging costs come in well under £1,000 — a significant saving over petrol.
Home charging cost
Home charging is by far the cheapest way to keep your Tesla topped up. At the Ofgem Q1 2026 price cap rate of 27.69p/kWh, here is what a full charge costs for each model:
| Model | Battery (usable) | Full charge cost | 0–80% cost |
|---|---|---|---|
| Model 3 RWD | 57.5 kWh | £15.54 | £12.43 |
| Model 3 Long Range | 75 kWh | £20.27 | £16.22 |
| Model Y RWD | 60 kWh | £16.22 | £12.97 |
| Model Y Long Range | 75 kWh | £20.27 | £16.22 |
| Model S | 100 kWh | £27.69 | £21.62 |
| Model X | 100 kWh | £27.69 | £21.62 |
For a driver covering 200 miles per week in a Model Y Long Range (3.7 mi/kWh real-world efficiency), you need approximately 54 kWh per week. At 27.69p/kWh that is £14.60/week or roughly £759/year.
If you are on an off-peak EV tariff such as Octopus Go (around 7–8p/kWh overnight), your annual cost drops to under £300 — less than a monthly petrol fill-up.
Tesla Supercharger cost
UK Supercharger pricing currently averages around 55p/kWh, though it varies by location and time of day (typically 40p–67p/kWh). Peak hours (4–8pm on weekdays) tend to be more expensive.
A typical 20–80% top-up on a Model Y Long Range (45 kWh) at a Supercharger costs approximately £24.75. A full session from near-empty costs around £41.25.
For a driver doing all their charging at public Superchargers (200 miles/week, Model Y LR), the annual cost would be approximately £1,540 — more than double the home charging cost.
Cost comparison: home vs Supercharger vs petrol
| Method | Rate | Annual cost (200 mi/wk) | Cost per mile |
|---|---|---|---|
| Home charging | 27p/kWh | ~£759 | ~7p |
| Off-peak tariff (e.g. Octopus Go) | 7–8p/kWh | ~£200 | ~2p |
| Supercharger | 55p/kWh | ~£1,540 | ~15p |
| Petrol (35 mpg, 132p/litre) | 132p/litre | ~£3,148 | ~19p |
Even at Supercharger rates, driving a Tesla costs significantly less per mile than an equivalent petrol car. Home charging is roughly 4× cheaper than petrol per mile.

How to reduce your charging costs
The single biggest way to reduce your Tesla charging costs is to charge at home overnight on an off-peak EV tariff:
- Octopus Go — around 7–8p/kWh overnight (midnight–5am). One of the best-value EV tariffs in the UK.
- British Gas Electric Driver — competitive overnight rates for EV drivers, typically 7p/kWh.
- E.ON Drive — overnight EV rate available, worth comparing.
- Use Superchargers less — rely on home charging for your daily driving and only Supercharge on long journeys.
- Pre-condition on charge — heating or cooling the cabin while still plugged in uses grid electricity rather than your battery, preserving range.

How much does it cost to charge a Tesla Model Y at home?
A Tesla Model Y Long Range (75 kWh usable) costs approximately £20.27 to charge from 0–100% at the current Ofgem rate of 27.69p/kWh. Charging to 80% (recommended for daily use) costs around £16.22. For a driver covering 200 miles per week, annual home charging costs roughly £759.
Is charging a Tesla cheaper than petrol?
Yes, significantly. Home charging a Tesla at 27p/kWh for 200 miles/week costs around £759/year. The equivalent petrol car (35 mpg) at 132p/litre would cost approximately £3,148/year — over 4× more expensive. Even on an average public charging tariff, an EV is cheaper to run than a petrol car.
What is the Supercharger cost per kWh in the UK?
Tesla Superchargers in the UK currently average around 55p/kWh for Tesla owners, though pricing varies by location (typically 40p–67p/kWh). This is higher than home charging rates but still well below petrol costs per mile. Non-Tesla EV drivers pay a higher rate at Superchargers.
