EV Tariff Calculator: find your cheapest UK electricity tariff
Tell us how much you drive, what charger you have at home, and how much electricity the rest of your house uses. We'll model seven UK electricity tariffs — including the standard variable price cap — and tell you which one is genuinely cheapest for your usage. The ranking is based on monthly cost only, never affiliate rate.
E.ON Next Drive
Approximate monthly electricity cost: £109.46
That's £42.67 less per month than the standard price cap.
Off-peak achievability check
Your 7kW charger over 6h of off-peak/night can deliver up to 1278kWh/month. You need 212kWh/month at your selected off-peak share — comfortable headroom.

How we calculate this
EV kWh from your car's real-world efficiency × monthly miles. Non-EV usage split 75% peak / 25% off-peak (households use some appliances overnight). OVO Charge Anytime is modelled with its EV-only off-peak quirk. Full assumptions on the methodology page.
