How much does it really cost to charge an EV at home in the UK?
Three free calculators that use current UK electricity tariffs and petrol prices to show you real numbers — not a national average that doesn't match your car or your tariff.
EV Home Charging Cost Calculator
Pick your EV (or enter your own battery size), your electricity tariff, and your weekly mileage to get cost per charge, per mile, and per year.
EV vs Petrol/Diesel Cost Comparison
See exactly how much cheaper (or not) running an EV is compared with a petrol or diesel car doing the same mileage.
Tesla Model 3 & Model Y Charging Cost Calculator
Pre-loaded with Tesla trim battery sizes and real-world efficiency, so you don't have to look them up.

Why home charging cost varies so much
Two EV drivers on the same street can pay very different amounts to charge, mostly for one reason: their electricity tariff. A driver on a dedicated EV/off-peak tariff charging overnight can pay a fraction of someone charging on a standard variable rate during the day. Battery size and real-world efficiency (miles per kWh) matter too, and both vary by model and driving style. These calculators let you plug in your own numbers rather than relying on a single average that may not apply to you.
Figures used in these calculators are UK averages and typical model specifications, current as of . They're a useful estimate, not a quote — check your own electricity tariff and vehicle efficiency for exact numbers. See About & Sources for details.
