Even with today’s higher electricity prices, EVs can be much cheaper to fuel than their petrol and diesel equivalents, especially if you have off-street parking and can charge your EV at home.
Based on the average UK domestic electricity price of 34p per kWh (December 2022), the average size EV costs about 10p per mile in fuel for urban driving (as opposed to motorway driving, which may drain your battery faster). This is around half the cost of petrol or diesel. If you can charge your EV overnight using an off-peak tariff, you can save even more.
You can also expect much lower servicing and maintenance costs driving an EV, and you won’t have to pay any road tax until 2025.
