Buying a used electric car in the UK: what to check

The UK used EV market has matured significantly. Volume from three-year-old lease returns has grown, and prices have settled below their peak. The right used EV can be excellent value, but the checks are different from buying a used petrol car.

Battery state of health

The most important EV-specific check is battery state of health (SoH) — the current capacity as a percentage of the original. A battery at 90% SoH on a 75 kWh car effectively has 67.5 kWh available. Most manufacturers offer diagnostic reports, and some dealers (Cazoo, Motorway resellers, franchised dealers) will show you a battery health certificate. Tools like OBD readers with EV-specific apps can read SoH from the car's own data if no certificate is provided.

Remaining manufacturer warranty

Most EV manufacturers provide a separate battery warranty of 8 years / 100,000 miles alongside the vehicle warranty. Check how much of this remains. If less than two years is left, factor potential battery costs into the purchase price, or look for a model with a longer remaining warranty.

Charging history

Frequent DC rapid charging at high rates can accelerate minor battery degradation compared to regular AC home charging. Some EVs log this in the service record or via manufacturer apps. It is worth asking — a car predominantly charged at home is preferable to one that has been rapid-charged daily.

DVLA and outstanding finance

As with any used car in the UK, run an HPI check to confirm there is no outstanding finance on the vehicle and that it has not been written off or stolen. The registration document (V5C) should be in the seller's name and match the car's details.

Charging cable and accessories

Ensure the Type 2 charging cable and the original EVSE tethered cable (if the car came with one) are included. Replacing a missing Type 2 cable costs £80–£200 depending on cable length and rating.

Frequently asked questions

How do I check the battery health of a used EV in the UK?

Ask the seller for a battery health certificate. Alternatively, an OBD2 reader with an EV-compatible app (e.g. Car Scanner, Torque Pro) can read SoH from the car's on-board diagnostics. Franchised dealers can usually run a manufacturer diagnostic.

Is it safe to buy a used Tesla in the UK?

Tesla's used market is large and well-documented. Check remaining battery warranty (8 years/150,000 miles for Model 3/Y), service history via the Tesla app and whether the car is under any open recalls. An HPI check for outstanding finance is still advisable.

Are used EVs more expensive to insure in the UK?

Insurance premiums for EVs have been higher than equivalent petrol models, partly due to repair costs and battery replacement uncertainty. This gap is narrowing as insurers accumulate claims data. Always compare quotes from multiple providers.
