Frequently asked questions
How much does it cost per mile to run an electric car in the UK?
At typical 2026 electricity rates, an EV costs around 5-8p per mile when charged mainly at home. This compares favourably with petrol cars at 15-20p per mile. The exact figure depends on your electricity tariff and how efficient your car is.
What is a good miles per kWh for an EV?
Most modern EVs achieve between 3 and 4.5 miles per kWh in real-world driving. Smaller, more efficient cars like the MG4 can achieve 4+ miles per kWh, while larger SUVs and performance EVs may only get 2.5-3 miles per kWh.
How does EV cost per mile compare to petrol?
An EV charged at home costs roughly 5-8p per mile, while a petrol car averaging 40 MPG costs around 16-18p per mile at current fuel prices. That makes an EV about 60-70% cheaper per mile to run.
Does cold weather increase EV running costs?
Yes. In cold weather (below 5 degrees C), EV efficiency drops by around 20-30% due to battery heating and cabin heating. This increases the cost per mile proportionally. Using a heat pump (fitted to most newer EVs) reduces this impact.
