This can cut your home charging cost by 60 to 70%. The cheapest EV tariffs in the UK offer overnight rates of 7 to 10p per kWh versus the standard 24.50p cap rate. Charging a 60kWh battery overnight costs approximately £4.20 to £6 at peak EV tariff rates. Best EV tariffs UK April 2026

You can use an EV tariff and charge via a standard 3-pin socket, though this is slower and less efficient. A dedicated 7.4kW home charger makes EV tariffs significantly more effective. Do EV tariffs affect my daytime electricity rate? Yes. EV tariffs have a higher daytime rate than the standard price cap in some cases — the savings come from moving consumption to off-peak hours. Calculate your total annual bill (not just the EV charging rate) when comparing tariffs. Can I switch to an EV tariff without switching my entire energy supply? No. EV tariffs are part of a complete energy tariff — you switch both gas and electricity (or electricity only if gas-free) to the EV tariff supplier. Are EV tariffs available for flat renters? Yes, if you have a home charger. Renters who can install a home charger (with landlord permission) can access EV tariffs. Without a home charger, public charging is the alternative — costs vary widely from 40p to 85p per kWh at public rapid chargers. |
