Different from the rest: the house stays on OVO's normal rate and every kWh that goes into the car is credited back down to 14p, whenever you charge. Unbeatable if you can't charge overnight; dearer than a 7–9p window if you can.
Assumes home charging with 90% of it in the window (100% for flat tariffs). Not sure of your efficiency? Pick your car from the car list.
Will your car fill up in the window? A 7 kW charger delivers about 6.3 kWh an hour into the battery. There is no window to worry about.
