A used EV can cost far less than a new one, if you check the right things first. Here’s what to look for on the battery, charging, warranty and price.
The used electric car market has done something that rarely happens in motoring: it has turned in the buyer’s favour. Early adopters paid list price, then depreciation took a large chunk out of it. If you’ve been waiting for the cheap seats, they’re here.
There’s a catch, of course. A second-hand EV puts most of its value into one expensive part you can’t see, can’t hear and can’t kick. Buy the wrong one and that bargain gets very expensive. Here’s how to avoid that.
Start with the battery, because in an EV it’s what the engine and gearbox are in a petrol car: the bit that decides whether you got a good deal. Every lithium-ion battery loses some capacity with age and use. The question is how much.
The figure you want is the state of health, usually shortened to SoH. It’s the battery’s usable capacity today as a percentage of what it held when new. A car showing 90% has lost about a tenth of its original range. That’s fine for a car several years old. A much lower figure on a relatively young car is a warning sign.
Some dealers now include a battery health certificate with their used EVs, and independent testing firms will do one for a fee, usually by plugging a diagnostic tool into the car’s OBD port (the same socket a garage uses to read fault codes). If the seller can’t or won’t provide one, take that into account when you make an offer, or walk away.
Don’t rely on the range shown on the dashboard. That “guess-o-meter” works from recent driving, so a car that has just been driven gently on a mild day can look much healthier than it is.
Owners of older Nissan Leafs have a well-worn workaround: a cheap OBD dongle and a phone app such as LeafSpy will show the battery’s real condition in a couple of minutes. If a private seller objects to you plugging one in, ask yourself why.
The free MOT history check on GOV.UK is just as useful for an EV as for anything else. Enter the registration and you’ll see every test result, the recorded mileage and any advisories. Look for mileage that jumps around, long gaps and repeated advisories.
EVs are hard on tyres and, oddly, on brakes. The instant torque wears tyres, while regenerative braking (the motor slowing the car and returning energy to the battery) means the brake discs get so little use they can rust. Advisories for corroded discs are common and worth checking.
What the MOT won’t tell you is anything about the battery. The test checks the car’s roadworthiness, not how much energy it can store. Cars in England, Scotland and Wales have their first MOT at three years old. In Northern Ireland it’s four years, and the testing is done separately by the DVA, so the history you get there looks different.
While you’re on GOV.UK, check for outstanding safety recalls too. Several early EVs have had battery-related recalls, and you want proof the work was done.
On a used EV, a battery health report is worth more than a shiny bonnet and a full service book put together.
Three names come up again and again at the sensible end of the market, and for good reason.
The Nissan Leaf is the cheap way in. Early cars with the smaller 24kWh and 30kWh batteries can be found for less than many used superminis, but expect a modest real-world range that falls further in winter. Later 40kWh and 62kWh versions are far more usable. Two caveats: the Leaf’s battery has no active cooling, so repeated rapid charging on a hot day can slow it down, and it uses the CHAdeMO rapid-charging plug, which is supported by fewer and fewer new chargers. If you mostly charge at home and drive locally, that’s not a problem. If you regularly drive up the M6, it is.
The Kia e-Niro and the Hyundai Kona Electric are cousins underneath, and the 64kWh versions are the ones to look for. Both offer a real-world range comfortably beyond 200 miles in decent weather, use the standard CCS rapid-charging plug and have a reputation for batteries that age well. The e-Niro is the more practical family car, while the Kona is smaller and a bit livelier. Avoid the smaller-battery Kona unless the price really reflects it.
Prices change from month to month, but older Leafs can be found for under £5,000, while 64kWh e-Niros and Konas typically sit in the low-to-mid teens of thousands depending on age, mileage and trim. Compare like with like: battery size matters far more than the alloy wheels.
Check the warranty. Kia’s battery cover runs for seven years or 100,000 miles, and Hyundai’s for eight years or 100,000 miles, both from the date the car was first registered. If you can buy a car with that cover still in place, you have a safety net for the most expensive part.
No. The Electric Car Grant, launched in July 2025, takes up to £3,750 off qualifying new electric cars with a list price of £37,000 or less. It does not apply to used cars, whatever an optimistic forecourt sign implies.
It does affect you indirectly, though. Cheaper new EVs add pressure on used prices, which is good news if you’re buying and less so if you’re thinking of selling in a couple of years.
Also remember that EVs are no longer free to tax. Since April 2025 they pay Vehicle Excise Duty: most cars registered from April 2017 pay the standard rate, which is £195 for the 2025/26 tax year, while older EVs registered before then pay a much lower rate.
That depends almost entirely on whether you can charge at home. With a driveway, a wallbox from a supplier such as Pod Point and an off-peak EV electricity tariff, you can be paying a few pence a mile. Home electricity also carries 5% VAT, compared with 20% at public chargers.
Rely on public rapid chargers from networks such as InstaVolt, and the sums change. Rapid charging often costs several times the off-peak home rate, and on some routes it can work out about the same as running an efficient petrol car. Fine for the occasional long trip. Expensive as your only option.
Before you buy, check the car comes with its charging cable for a home or destination charger (the Type 2 cable), and test it if you can. Make sure the car will rapid charge too: a short session at a public charger will tell you whether it’s working properly and how quickly it charges.
Finally, put a used EV through the same checks you’d do on any car. Get an HPI check for outstanding finance, look at the service history (EVs need less servicing, but still need some) and make sure the heating works properly. A car with a heat pump will lose less range in winter, which matters more than you might expect in January in Britain.
A used electric car can be excellent value, but only if you know what condition the battery is in. Get a state-of-health report, check the MOT history and recall status on GOV.UK, and favour models with proven batteries and warranty left, such as the 64kWh Kia e-Niro or Hyundai Kona. The Electric Car Grant doesn’t apply to used cars, and the savings mostly depend on being able to charge at home.
Used electric car prices have collapsed, and that makes some proper bargains. Here’s how to check the battery, avoid the known lemons and work out what one will really cost you.
New gadgets launch every week, and most of them can wait. Here’s how to tell the few tech changes that really need your attention from the marketing noise.
Smart indoor gardens promise fresh herbs and salad on a worktop, with automatic lights and watering. What the kit actually does, what it costs to run and who should buy one.
Temu’s prices are tempting, but a cheap gadget is only a bargain if it works, arrives and is safe. Here’s how to judge the risks before you buy.
