How much does it cost to charge an EV at home?

Charging at home is almost always cheaper than public chargers and far cheaper than petrol. The cost depends on three things: how far you drive, your car’s efficiency (most manage 3–4 miles per kWh), and your electricity tariff. A smart EV tariff with a cheap overnight rate can cut home-charging costs dramatically — and pairing your charger with solar panels and a battery can make much of your driving effectively free.

EV charging FAQs

Is it cheaper to charge an EV at home or in public?

Home charging is typically far cheaper, especially on a smart overnight tariff. Public rapid chargers can cost several times more per mile.

Can I charge my car from solar panels?

Yes. A solar-aware home charger can send surplus daytime solar straight into your car, so you drive on your own free electricity. See our guide to solar and EV charging.
