How this is worked out
Annual energy = mileage ÷ real-world efficiency (mi/kWh). We split that by your home/Supercharger share and apply each rate. Defaults (home 24.5p, Supercharger 41p) are examples checked 2026-07-13 — a smart EV night tariff can be far lower (~7.5p). Sources: Ofgem price cap, Tesla Supercharging.
Questions
How much does it cost to charge a Tesla at home in the UK?
It depends entirely on your tariff. At a typical ~24.5p/kWh a Model Y using ~3.7 mi/kWh costs roughly 6–7p per mile; on a dedicated EV night rate near 7.5p/kWh that drops to around 2p per mile. Edit the rate above to your own supplier.
Is Supercharging more expensive than charging at home?
Usually, yes. Supercharger pricing in the UK is well above most home tariffs, so the more you charge at home the lower your annual cost. Membership reduces the Supercharger rate.
