Typical rating and how we worked this out
This page uses a typical rating of 7kW for a EV home charger (7kW); published figures for this appliance range from 7kW to 7kW. A 7kW home charger's running cost is really about the electricity delivered to the battery, not the charger itself — a typical top-up of around 30kWh (roughly 100 miles of range) three times a week is used here. Charging on a cheap overnight EV tariff rather than a standard rate typically cuts this cost by more than half. The running cost follows the same formula used across this site: watts ÷ 1,000 × hours × unit rate. Typical use is modelled as 3 top-ups a week, about 30kWh each, which is how the per-day, per-week and per-year figures above were calculated — see the cost-to-run calculator to change the wattage, hours or region yourself.
Rate used: Ofgem price cap, 1 October to 31 December 2026, GB average electricity — 26.32p/kWh (excl. VAT, removed 1 Oct 2026–31 Mar 2027).
