Question 1

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

Accepted Answer

At the Ofgem price cap of 24.67p/kWh (Q2 2026), charging a Tesla Model Y Long Range (77 kWh battery) from 0–100% costs around £19. On an EV tariff (6–9p/kWh overnight from Octopus, E.ON or British Gas), it drops to just £5–£7. Annual home charging costs roughly £600–£700 per year at standard rates.

Question 2

How much does Tesla Supercharging cost per kWh in the UK?

Accepted Answer

Tesla Supercharger pricing in the UK uses two time bands and two tiers. Members (£9.99/month) pay 25p/kWh off-peak (11PM–9AM) and 41p/kWh peak (9AM–11PM). Non-members pay 35p off-peak and 60p peak.

Question 3

Is it cheaper to charge a Tesla at home or at a Supercharger?

Accepted Answer

Home charging is cheaper, especially on an EV tariff. At 7–9p/kWh overnight vs 41–60p/kWh at a peak Supercharger, home charging on an EV tariff costs a fraction of the price. Even at standard home rates (25p/kWh), it's cheaper than Supercharging.

Question 4

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

Accepted Answer

For a Tesla Model Y (3.7 miles/kWh efficiency) charged at home (25p/kWh), the cost is approximately 7p per mile. On an EV tariff (7p/kWh), it's around 2p per mile. At a peak Supercharger (41p/kWh member, 60p non-member), it's around 11–16p per mile. Compare this to a petrol car at 35 mpg costing approximately 21p per mile at current prices (158p/litre).
