But one of the first questions on the minds of most EV drivers is: how much does it really cost to charge an electric car at home? In this guide, we’ll look at the factors that influence your home EV charging prices in the UK and, crucially, how you can leverage smart charging to find the cheapest way to charge your electric car at home.
