Compare Energy Tariffs

An EV tariff offers cheaper electricity during off-peak hours (typically midnight-5am) designed for charging electric vehicles at home. Rates can be as low as 7p/kWh compared to the standard 24p/kWh, saving up to £800/year on charging costs. The cheap rate applies to all electricity usage during off-peak hours, not just EV charging.

A typical EV driver covering 10,000 miles/year could save £400-£800/year by switching to an EV tariff. At 7p/kWh off-peak, charging costs about £175/year vs £600/year at the standard 24p/kWh rate. You can save even more by running other appliances during off-peak hours too.
