Should I buy a used EV?
Used electric cars are becoming an increasingly realistic alternative to petrol and diesel cars. Some early EVs have depreciated heavily, putting cars that were expensive when new within reach of used-car buyers.
That doesn’t automatically make every used EV a bargain. The battery, remaining warranty, access to charging and potential cost of specialist repairs all need to be considered. The right answer depends as much on how you use a car as on the car itself.
Is an EV right for me?
The first question is whether an electric car suits your driving.
EV ownership is generally easiest if you can charge at home, particularly if you can use a cheaper overnight electricity tariff. Starting most mornings with a charged battery also removes much of the need to visit public chargers during normal day-to-day driving.
Public rapid charging is typically several times more expensive than a good value home charging tariff. For this reason, you should plan to do the majority of charging at home for maximum savings.
Think about journey length as well. If most of your journeys are comfortably within the car’s real-world range, an EV can be very convenient. If you regularly drive more than 200 miles at a time, it doesn’t necessarily rule one out, but charging speed, motorway range and the public charging network become much more important considerations.
Someone doing a 30-mile daily commute with a driveway has very different requirements from someone regularly travelling hundreds of miles and relying entirely on public charging.
Do you like the driving experience?
For many people, this is one of the easier questions to answer.
Electric cars are generally quiet and smooth, with no conventional gear changes and immediate response from the electric motor. Most are straightforward to drive, particularly in urban traffic.
It’s still worth test-driving one before buying. Regenerative braking, which slows the car while recovering energy into the battery, can initially feel different from a conventional car, and the strength of it varies considerably between models.
The used EV market
One of the attractions of buying used is avoiding some of the depreciation already absorbed by the first owner.
Used EV values fell substantially during the earlier development of the market, but as the used EV market strengthens and customers gain confidence in buying used EVs, used prices are slowly increasing. Auto Trader reported in July 2026 that average used EV prices had returned to year-on-year growth for the first time since 2022. Three-to-five-year-old EVs averaged £19,295 in June 2026.
That said, EVs which were once worth over £40,000 when new are now on sale as used cars for less than half the price, just 4 years later. This depeciation creates a potential opportunity for savvy used EV buyers.
But remember, the purchase price is just one piece of the puzzle to consider when buying used.
Battery condition
The high-voltage battery is one of the most important parts of a used electric car. It is als by far the most expensive component of a used EV and that’s why you need to pay close attention to it.
All batteries gradually lose some usable capacity as they age. What matters is how much capacity remains and whether there is evidence of an abnormal problem.
Don’t simply assume that a car showing a normal driving range has a healthy battery. Ideally, obtain a meaningful battery-health assessment, particularly when buying an older EV or buying outside a manufacturer’s approved-used scheme. A good used car dealer will publish a battery health certificate along with the car advert.
Maintenance and reliability
Electric cars have a simpler mechanical powertrain than combustion cars. There is no conventional engine oil, exhaust system, timing belt or clutch, and an electric motor contains far fewer moving components than a combustion engine.
That doesn’t mean an EV has little that can go wrong.
Modern EVs depend heavily on electronics, control modules and software as well as their high-voltage systems. The mechanical maintenance burden can therefore be lower while electrical or electronic faults remain possible.
EVs can also be relatively heavy because of their battery packs. Tyres, suspension and brakes still need checking like any other used car. Regenerative braking can reduce use of the conventional friction brakes, but that doesn’t eliminate the need to inspect them.
The service history still matters, even if the list of routine servicing items is shorter than on a petrol or diesel car.
Why is warranty is more important with a used EV
The gold standard when buying a used EV is to buy a car with remaining warranty covering the battery and the major drive components.
Buying a used EV outside of warranty is currently much riskier with EVs than with tradition engine-powered cars.
Battery warranty receives a lot of attention, but the battery isn’t the only expensive component in an EV.
The electric drivetrain typically includes one or more traction motors, reduction gearing and power electronics. The inverter controls electrical power supplied to the motor, while an onboard charger converts AC electricity from a home or public AC charger for storage in the battery. Thermal-management equipment controls temperatures within the battery and drivetrain.
Failures of these components is becoming less common, but they can be hugely costly to repair.
Part of the reason that repairs are so expensive is the availability of expertise in EV repairs and the supply chain for EV parts.
The EV repair industry and supply chain
The independent EV repair industry is growing, but it isn’t yet as mature as the repair network for conventional cars. The supply chain for spare engine parts has had decades to mature. This just isn’t the case for EV specific parts.
The Institute of the Motor Industry reported in 2026 that around 35% of the UK technician workforce was qualified to work on EVs, and it continues to warn about the need for more EV-trained technicians as the number of electric cars grows.
So when buying a used EV, it’s important to be aware that problems may take longer to fix and if outside of a warranty, may involve unpredictable costs.
This situation should improve as more EVs enter the used market and more independent specialists gain the necessary skills. For now, however, it remains part of the risk calculation.
Miles Better Off used EV checklist
Before buying a used electric car, ask yourself:
- Can I charge reliably at home or somewhere convenient?
- Does the car’s realistic range comfortably cover most of my journeys?
- How often will I need rapid public charging?
- Do I actually enjoy driving the car?
- Is the used price attractive compared with equivalent petrol, hybrid and newer EV alternatives?
- Has the high-voltage battery’s condition been properly assessed?
- How much battery warranty remains?
- What warranty covers the motor, inverter, charger and other major drivetrain components?
- Is there a good service and maintenance history?
- If I plan to keep the car beyond warranty, do I accept that repairs can take longer and involve unpredictable costs? If I lose access to the car for complex repairs, do I have backup transport?
A used EV can make particularly good sense where you can charge cheaply at home, most journeys fall comfortably within its range and the car retains meaningful battery and drivetrain protection.
An older EV outside warranty needs more thought. The purchase price may be attractive and routine mechanical maintenance relatively simple, but battery and high-voltage drivetrain repairs can carry significant financial exposure. As with any used car, the cheapest example isn’t necessarily the one that will leave you Miles Better Off.
