Things to consider before switching to an EV tariff
The off-peak rate is only part of the picture. EV tariffs split the day into two pricing tiers: a cheap overnight rate and a peak rate during the day. The peak rate on some EV tariffs is higher than the standard price cap rate, which means if you use a lot of electricity during the day, your overall bill could be higher than on a standard tariff even with cheaper overnight charging.
Before switching, work out how much electricity you use during peak hours versus how much you will save overnight. If you work from home and use a lot of daytime electricity, a high peak rate can eat into the overnight savings. If most of your household electricity use is in the evening or you can shift usage to the off-peak window, an EV tariff is likely to save you money.
Most EV tariffs also require a smart meter. If you do not have one, contact your supplier to arrange installation, which is free. Some tariffs also require a specific smart charger or wallbox. Check compatibility with your charger before switching. See our full energy tariff comparison to see current EV and standard deals side by side.
