Frequently asked questions
Are EVs really cheaper to run?
Charging at home overnight typically costs a fraction of petrol per mile. Public rapid charging narrows the gap considerably.
What about battery replacement?
Modern EV batteries are warranted for 8 years or 100,000 miles and rarely need full replacement within that window.
Does this account for road tax changes?
Yes — from April 2025 EVs pay VED, and the calculator reflects current UK rates.
