The questions behind the numbers

How much does it cost to charge an electric car at home?

On an overnight EV tariff of around 7p per kWh, a typical car doing 8,000 miles a year costs roughly £140 a year to charge. On a standard tariff of about 25p it is closer to £500. The same mileage on public rapid chargers at 79p is about £1,600.

Is it cheaper to charge at home or at a public charger?

Home is dramatically cheaper. Public rapid charging in the UK runs around 79p per kWh, against roughly 7p on an overnight EV tariff at home. That is about eleven times the price for the same electricity.

Do I need a 7kW charger, or will a three-pin plug do?

A three-pin granny lead draws around 2.3kW and takes most of the night for a partial charge. It is also not designed for daily high-load use. A 7kW wall charger charges roughly three times faster, is safer for continuous load, and is the only way to use most cheap overnight tariffs properly.

Most installs are done in a day. Renovolt fits chargers from £900 including VAT across Bridgend, Pencoed, Cowbridge, the Vale and Cardiff, with a fuse-board check included on every job.
