Every mainstream electric-car tariff in Britain: the cheap rate, the hours, the catches, and what a typical driver pays. Rates checked 29 September 2026.
Three things decide it. First, whether your car or charger can do smart scheduling — if not, Octopus Go, EDF GoElectric and British Gas EV Power work with anything. Second, how much electricity the rest of your house uses in the daytime: tariffs with a 30p peak rate punish heavy daytime use. Third, whether you can charge overnight at all; if not, OVO Charge Anytime's 14p at any hour is the one to look at. The calculator ranks them for your own mileage and car.
