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).

With 7,456 miles a year, always charging at home costs about £629 on the standard tariff and £182 off-peak on an EV tariff: you save £447 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.
