The cheapest miles come from a home charger on an off-peak EV tariff, which gives you several hours of very low-rate electricity overnight — timed to charge the car while you sleep.
The savings are large enough that, for higher-mileage drivers, a home charger and the right tariff can pay back quickly versus standard-rate or public charging. This is the single biggest lever on EV running cost — bigger than which car you buy.
Every car page lets you compare home off-peak, public AC and public rapid so you can see the difference for your mileage. If you're weighing up a home charger, our installer enquiry can help. How each rate feeds the cost model is on the methodology page.
