Buying a used EV in the UK: what to check
Battery health, warranty transfer, charging hardware and the used-EV-specific checks worth making before you hand over any money.
Last updated: · How we check our figures
Used electric cars are now some of the best value on the UK market, but the checklist is different from a used petrol car. Mileage and service history matter less; battery condition and warranty position matter far more.
Battery health
State of health is the number that decides what the car is worth. Typical degradation is modest — on the order of a couple of percent a year — but individual cars vary with charging habits and climate.
- Ask for a battery state-of-health report, or pay for an independent test
- Check the indicated range at 100% against the original figure
- Frequent rapid charging and long spells at 100% accelerate degradation
Warranty transfer
Battery warranties usually run to eight years or 100,000 miles and normally transfer to subsequent owners, but the terms and the capacity threshold vary by manufacturer.
- Confirm remaining battery warranty in years and miles
- Check the guaranteed minimum capacity, often around 70%
- Confirm the main vehicle warranty position separately
Charging hardware and cables
Check which cables are included, whether the car supports the rapid-charging speeds you expect, and whether any optional heat pump or charging upgrade was specified when new.
Paperwork, tax and recalls
Confirm outstanding finance, recall status, service history for the high-voltage system, and the vehicle tax position under the current VED rules.
Before you commit, run the car through our used EV battery health and range checker: it estimates state of health from age and mileage, tells you whether the battery warranty is still live, and gives you a summer and winter range figure to sanity-check against the seller's claims.
