Rates as published by each supplier in November 2026, including the temporary 0% VAT on electricity until 31 March 2027. Octopus rates from its tariff data for the West Midlands; other suppliers quote national averages. Home charging: 7,000 miles at the DESNZ average for an electric car, with 65% of charging done at home (Roland Berger estimate). Only the car's charging is costed here.
What the cheap rate covers
All of these except OVO's Charge Anytime charge the cheap rate for everything the home uses in those hours, so a dishwasher or a battery can use it too. Charge Anytime only discounts the car's smart charging.
Outside the cheap hours, Octopus Go charges 33.33p against 25.6p on the price cap, so the tariff only pays if enough of your use moves overnight. The calculator below weighs both for your home.
