Buying a used electric car in the UK — battery health, charging and what to check

Early electric cars lost value quickly, which means there are now plenty of used EVs at prices that make sense. The running cost case is strong if you can charge at home. The things to check are different from a petrol or diesel car, so here is the EV-specific list.

Battery health is the big one

An EV's battery slowly loses capacity. A typical modern battery keeps well over 90% of its capacity after several years, but individual cars vary with climate, charging habits and mileage.

How to check it:

• Ask for a state-of-health (SoH) reading. Many cars show it in a service menu, and dealers and independent EV specialists can read it with a diagnostic tool. Some listing sites now show a battery certificate.
• Do a range sanity check. Charge to 100% (or note the percentage) and compare the predicted range with the manufacturer's original figure. Expect a gap, but a large one deserves a question.
• Check the battery warranty. Most manufacturers cover the battery for 8 years or around 100,000 miles against dropping below a stated capacity, often 70%. Confirm what is left and whether it transfers to you.

Charging: work out your real life first

• Home charging is what makes an EV cheap to run. If you have off-street parking, a 7 kW home charger fills most cars overnight. If you do not, you will rely on public charging, which costs more and takes planning.
• Check the car's charging speeds. Older or cheaper EVs may charge slowly on rapid chargers, which matters on long trips.
• Cables. The car should come with a Type 2 cable for public and home AC charging. Some also include a three-pin "granny" cable. Replacements are not cheap.

Other EV-specific checks

• Tyres. EVs are heavy and quick off the line, so tyres wear faster. Budget for a set if they are close to the limit.
• Brakes. Regenerative braking means pads and discs last a long time, but they can also corrode from lack of use. Listen for grinding and check for rust lips on the discs.
• Software and app access. Make sure the previous owner has removed the car from their account so you can use the app and any connected features.
• Heat pump. Cars with a heat pump lose less range in winter. It is often an option, so check the spec.
• Service history still matters. Fewer moving parts, but coolant, brake fluid, cabin filters and software updates still need doing.

The paperwork is the same

Run the MOT history check, a paid vehicle history check for finance and write-off status, and follow the general buying checklist. Electric cars are written off and clocked just like any other.

Tax

Electric cars registered from 1 April 2025 pay vehicle tax, and older EVs that were previously zero-rated now pay the standard rate. Check the current position on GOV.UK before assuming an EV is tax-free.

Is a used EV right for you?

Yes, probably, if you can charge at home and most journeys are under 150 miles.

Think carefully if you park on the street, do regular 300-mile days, or tow. A plug-in hybrid or an efficient petrol may suit better.
