What to check before buying a used EV: the five checks that only apply to electric cars

Buying a used electric car is mostly like buying any used car: the MOT history, the paperwork, the seller and the price all matter in the same way. But there are five checks that only apply to EVs, and two of them, the battery's health and who actually owns the battery, can cost you thousands if you skip them. Here's the list, in the order worth doing it.

What should you check before buying a used electric car?

Check the battery's measured health, who owns the battery, how much battery warranty is left, the charging kit and how you'll charge it, and then everything you'd check on any used car. In order:

The rest of this guide takes them one at a time.

How do you check a used EV's battery?

Ask for a measured state-of-health figure and the amount of battery warranty left. State of health is the battery's capacity now as a percentage of new, and it's what decides the real-world range. Approved-used schemes such as Volkswagen's and BMW's include a battery report, the AA's Comprehensive and Advanced inspections include an electric battery test, and specialist testers plug into the car. A range figure on the dashboard isn't a measurement, because it moves with the weather and the last few journeys.

Used EV battery health explained covers what a good figure looks like and the battery warranties by make, from the manufacturers' own pages.

Do you own the battery on a used EV?

Usually, but not always, and on some early cars it's the most expensive thing to get wrong. Renault sold many Zoes with the battery on a separate hire agreement rather than included in the car, and Nissan offered a Leaf finance package, Leaf Flex, with the battery leased within it. On those cars the battery belongs to a finance company, the monthly payments carry on after you buy the car, and the hire has to be transferred to you properly.

If the car is a Zoe, check before anything else: do you get the battery with a used Zoe? covers how to tell, how the transfer works and what a buy-out costs. On any EV from the early years, ask the seller directly: "Is the battery owned outright, or is there a battery lease or hire agreement?" Get the answer in writing in your messages, and ask for the paperwork if there's any doubt.

How much battery warranty is left?

Work it out from the date of first registration and the mileage, against the manufacturer's terms. Most battery warranties run 8 years or 100,000 miles, whichever comes first, separately from the car's main warranty, and most promise the battery will hold at least 70% of its capacity in that time. Kia, MG, Volkswagen and Renault say their battery cover passes to the next owner.

Both limits matter. A seven-year-old car has a year of battery cover left at best. A busy four-year-old car can hit 100,000 miles first, and battery electric cars do the most miles of any fuel type: 9,400 a year on average in England in 2025, according to the Department for Transport. The MOT history shows the mileage at every test from the car's third birthday, so you can check how fast it's using up the cover. What is good mileage for a used car has the averages.

What should you check about charging?

Three things: the kit, the connector and your own setup.

• The cables. Check the charging cable or cables are in the car. Missing ones are a cost and a hassle, and the AA's EV inspection tiers check the charge port and charging lead condition for a reason. Look at the charge port for damage while you're there.
• The connector. Check which rapid-charging connector the car uses and that the rapid chargers you'd rely on support it. Not every EV uses the same one.
• Charging at home. Most of the cost advantage of an EV comes from cheap home charging. If you live in a flat you own or rent, with your own off-street parking, the government's chargepoint grant gives 75% off the cost of buying and installing a home charger, up to £500, for an eligible vehicle. Homeowners in houses aren't eligible. Check the details on GOV.UK before you count on it.

Then test it. Ask to plug the car in, or see it charging, during the viewing. A car that won't take a charge has a fault you need to know about before you pay, and the on-board charger is a documented failure on some models.

What should you check on any used EV that you'd check on any car?

All of it. An EV still needs an MOT from its third birthday, it still has tyres, brakes and suspension, and it can still have finance owing, a write-off record or a mileage that doesn't add up.

• The MOT history. Free on GOV.UK, with every test, advisory and mileage reading. Tyres, brakes and suspension feature on EVs as on any car. MOT advisories explained shows how to read the record.
• Recalls. Check for outstanding safety recalls, which are usually fixed free; how to check car recalls has the free official routes.
• Finance, theft and write-offs. The same paid checks as on any car, and they matter as much.
• The test drive. Listen for knocks from the suspension, check the brakes pull up straight, and watch how the range estimate changes over a few miles.

What does the used EV market look like?

Busy, and getting busier. The SMMT reported used battery electric car sales up 67% to 110,761 in the second quarter of 2026, 5.5% of all used car sales. More choice is good for buyers, but it also means more early EVs with older batteries and unusual ownership arrangements reaching the market. Buyers are cautious: in a survey published by the lender Startline in August 2026, 57% of potential buyers said they wouldn't buy a used EV without an independent battery check.

Which of these checks can a report do for you?

Start with what nobody can do from a registration: measure the battery. State of health is read from the car itself, so no records-based check, ours included, can tell you it. And we don't see battery lease agreements: those sit with the finance company that holds the battery.

What a check can do is the rest of the list, and it starts with the official record everyone uses. Our free scan reads the car's full DVSA MOT history, plots the mileage so you can see how much battery warranty is likely left, and flags advisories that keep coming back. It reads the advert against that record, so claims like "full warranty" or "low mileage" are checked against the car's real age and mileage rather than taken on trust. And it checks the car against the known faults for that model, which on EVs include documented faults such as the Zoe's on-board charger failing and the early 30kWh Leaf losing capacity unusually quickly. The Zoe and the Leaf don't have enough documented faults yet for a page of their own, but our Renault and Nissan pages cover the rest of each range.

The Provenance Check adds finance, theft and write-off records, with keeper history, and includes the Smart Check's seller questions and negotiation figure. That's the part of a used EV purchase that's identical to any other car, and just as expensive to get wrong.

So what should you actually do?

Put the advert and the registration into the free scan before you contact the seller. Then ask two questions in writing: is the battery owned outright, and can they give you a measured state-of-health figure? If the car's still in the running, the same report upgrades on the same link with nothing re-run, so starting free costs you nothing if the answers come back wrong.
