At a standard home electricity rate of 24–28p/kWh, charging a Tesla Model Y Long Range from 0–100% costs around £19–£22. On an EV tariff (6–9p/kWh overnight), it drops to just £5–£7. At a Supercharger during peak hours (41–60p/kWh), the same charge costs around £32–£46. For most UK drivers who charge at home overnight, annual 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 Q2 2026 price cap rate of 24.67p/kWh, here is what a full charge costs for each model:
| Model | Battery (usable) | Full charge cost | 0–80% cost |
|---|---|---|---|
| Model 3 RWD | 60 kWh | £14.80 | £11.84 |
| Model 3 Long Range | 79 kWh | £19.49 | £15.59 |
| Model Y RWD | 63 kWh | £15.54 | £12.43 |
| Model Y Long Range | 77 kWh | £19.00 | £15.20 |
| Model Y Performance | 79 kWh | £19.49 | £15.59 |
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 24.67p/kWh that is £13.34/week or roughly £693/year.
If you are on an EV tariff such as Octopus Go, E.ON Drive Next or British Gas Electric Driver (around 6–9p/kWh overnight, typically midnight–5AM), your annual cost drops to under £250 — less than a monthly petrol fill-up.
Tesla Supercharger cost
UK Supercharger pricing uses two time bands. With a Charging Membership (£9.99/month): 25p/kWh off-peak (11PM–9AM) and 41p/kWh peak (9AM–11PM). Without membership: 35p off-peak and 60p peak.
A typical 20–80% top-up on a Model Y Long Range (~46 kWh) at a Supercharger costs approximately £19 at member peak rates or £28 without membership. Off-peak member rate brings that down to £12.
For a driver doing all their charging at Superchargers during peak hours with a membership (200 miles/week, Model Y LR), the annual cost would be approximately £1,152. Without membership that rises to £1,686/year. Charging off-peak with membership drops to around £703/year.
Cost comparison: home vs Supercharger vs petrol
| Method | Rate | Annual cost (200 mi/wk) | Cost per mile |
|---|---|---|---|
| Home (standard rate) | 24–28p/kWh | ~£675–£787 | ~6–8p |
| Home (EV tariff overnight) | 6–9p/kWh | ~£169–£253 | ~2–3p |
| Supercharger member (peak) | 41p/kWh | ~£1,152 | ~11p |
| Supercharger non-member (peak) | 60p/kWh | ~£1,686 | ~16p |
| Supercharger member (off-peak) | 25p/kWh | ~£703 | ~7p |
| Petrol (35 mpg, 158p/litre) | 158p/litre | ~£2,134 | ~21p |
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.

| Model | Real-world efficiency | Annual home cost |
|---|---|---|
| Model 3 RWD | 4.1 mi/kWh | ~£626 |
| Model 3 Long Range | 4.0 mi/kWh | ~£642 |

| Model Y Long Range | 3.7 mi/kWh | ~£693 |
| Model Y Performance | 3.5 mi/kWh | ~£733 |
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 / Intelligent Octopus Go — around 6–7p/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 6–9p/kWh.
- E.ON Drive Next — overnight EV rate around 6–8p/kWh, worth comparing.
- Supercharge off-peak — charging at a Supercharger between 11PM–9AM drops member rates to 25p/kWh, nearly half the peak price.
- 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 24.67p/kWh. Charging to 80% (recommended for daily use) costs around £15.20. On an EV tariff (6–9p/kWh overnight), a full charge drops to just £5–£7. For a driver covering 200 miles per week, annual home charging costs roughly £693.
Is charging a Tesla cheaper than petrol?
Yes, significantly. Home charging a Tesla at 25p/kWh for 200 miles/week costs around £700/year. On an EV tariff (6–9p/kWh overnight), it drops below £250/year. The equivalent petrol car (35 mpg) at 158p/litre costs approximately £2,134/year — over 3× more expensive. Even Supercharging at peak rates is cheaper than petrol.
What is the Supercharger cost per kWh in the UK?
Tesla Superchargers in the UK charge 25p/kWh off-peak (members) (11PM–9AM) and 41p/kWh peak (members) (9AM–11PM) for Tesla owners. Rates vary slightly by location. A Tesla Charging Membership (£9.99/month) gets you the lower end of each band.
