EV tariff vs standard tariff: which is cheaper?
Written by EV Charge Compare · Last reviewed 6 Nov 2026 · Live figures update from the prices we check
For most drivers who charge at home overnight, an EV tariff is cheaper. The cheapest overnight rate we track is typically about 7.9p per kWh, against the price cap unit rate on a standard tariff. But daytime rates on EV tariffs can be higher, so it depends on how much you drive and when you use electricity.
A quick example
We'll show a worked example here once we have current overnight and price cap rates.
When an EV tariff is usually cheaper
- You drive a fair amount and charge at home overnight.
- You can move some home use, like washing, to the cheap hours.
When a standard tariff might be cheaper
- You drive very little.
- You use lots of electricity during the day and the EV tariff's daytime rate is higher.
What is the price cap?
The price cap limits the unit rate and standing charge on standard variable tariffs. Ofgem sets it every three months. It's a limit on rates, not on your total bill. See Ofgem's price cap page.
This is an estimate. Check final prices with the supplier. We don't cover every tariff.
