Charging at home

Charging at home from 20 to 80%

On a standard tariff, the time makes no difference: the same price at any hour. On an EV tariff, charge in the off-peak window (23h30 to 5h30; yours are in your tariff details).

Standard (price cap)
£0.2632/kWh, Ofgem price cap unit rate		£19.46
EV tariff, off-peak
£0.0760/kWh, 23h30 to 5h30		£5.62
EV tariff, peak
£0.3500/kWh: avoid charging at these times		£25.87
Ofgem price cap
£0.2632/kWh, price cap unit rate		£19.46

With 7,456 miles a year, always charging at home costs about £552 on the standard tariff and £160 off-peak on an EV tariff: you save £393 a year. Note: on an EV tariff the peak rate is usually higher than the standard rate, so it pays off most if you can also move other usage into the off-peak hours.

Prices including VAT, from the Ofgem price cap and suppliers’ EV tariffs, checked on 2026-10. Includes 10% charging losses.
