How to Choose the Cheapest EV Tariff in the UK

If you own an electric vehicle, choosing the right tariff can make a big difference to charging costs. Many EV tariffs in the UK offer cheaper electricity overnight, with some off-peak rates costing as little as 7–9p per kWh. Charging at the right time can make running an electric car significantly cheaper than using a standard electricity tariff.

An EV tariff is designed for electric car owners and usually offers much cheaper electricity during quieter hours, often overnight when demand is lower. In return, daytime electricity can sometimes cost more, which is why choosing the right tariff depends on how and when you normally charge your car. Most off-peak charging windows run between late evening and early morning, although exact times vary between suppliers.

When comparing the cheapest EV tariffs in the UK, it helps to look beyond the headline price. A low overnight rate matters, but so do daytime costs, standing charges, and whether a smart meter or compatible charger is required. Some tariffs work best for drivers who charge every night, while others are better for more flexible charging habits.

Charging a typical 60 kWh battery on a standard tariff can cost more than three times as much compared with an off-peak EV tariff. For many drivers, this means potentially saving hundreds of pounds each year simply by switching to a tariff better suited to home charging.

Choosing the right EV tariff for your routine

The best EV charging tariff in the UK will depend on your routine. If you regularly charge overnight, an off-peak tariff may offer the biggest savings. If your charging times vary, it may be worth comparing flexible options that suit irregular schedules. Taking the time to compare tariffs carefully can make home EV charging much cheaper over time.
