How much does it cost to refuel?
Filling a 50-litre tank with petrol now costs £93.43, according to government data.
The average electric vehicle can be fully charged for five times less - just £18.
You'll need to top it up twice as many times per year as a petrol car, but you'll still pay 2.7 times less by going electric.
It costs 9p to drive a mile in an electric vehicle, and 24p in a petrol-fuelled car.
Over a year and 6,800 miles, that adds up to a £1,014 saving - as long as you use a home charging station. Since they cost around £950, you'll typically make your money back within a year.
And even if you only use public chargers, you'll still save £548 per year.
