Should you buy a used electric car in 2026? Pros, cons and who it suits

Should You Buy a Used Electric Car in 2026? | Rooster

For most drivers who can charge at home, a used electric car is now one of the cheapest ways to run a car in the UK. Used EV prices have stopped falling, batteries are lasting far longer than people feared, and charging overnight costs a fraction of petrol. It is a worse deal if you rely on public rapid chargers, cover very high mileage, or need to tow or drive long distances every week.

This guide sets out what has changed in the used EV market, what you save and what you don’t, how risky the battery really is, and who a second-hand EV suits.

Last updated 27 October 2026. Market figures come from the SMMT, Auto Trader, Zapmap and Ofgem (see the sources at the end). Tax rules may change at the Autumn Budget on 28 October 2026.

Key takeaways

Used EV sales rose 67% in the second quarter of 2026, and one in 18 used car buyers chose a fully electric car.
Used EV prices are rising again, especially for three to five-year-old cars, after the sharp falls of 2023 and 2024.
Charging at home on an EV tariff costs around 2p a mile, against roughly 17p a mile for a typical petrol car.
Public rapid charging averages 79p/kWh, or about 24p a mile, which can make an EV dearer to run than petrol.
EV batteries lose around 2.3% of capacity a year on average, so an eight-year-old car typically keeps over 80% of its range.
From April 2028 EVs will pay a new 3p-a-mile tax on top of standard car tax.

Is now a good time to buy a used electric car?

The used EV market has turned a corner. In the second quarter of 2026, 110,761 used battery electric cars changed hands, up 67% on a year earlier, according to the SMMT. That took EVs to 5.5% of all used car sales, up from 3.3% a year before. Rising fuel prices did a lot of the work: demand jumped most sharply in April and May.

Prices have followed. Auto Trader reported that used EV demand was up 40% year on year in September 2026 while supply grew only 26%, and electric was the only fuel type where used prices rose. In August, three to five-year-old EVs were up 9.4% year on year on a like-for-like basis.

What that means for you: the bargain-basement prices of 2024 are fading, particularly on popular three to five-year-old models. But there is far more choice than there was, and plenty of cars are still well below their original list price. Our guide to used electric car depreciation explains why prices fell and what is happening now.

What are the advantages of a used EV?

Much lower running costs if you charge at home. This is the big one. Electricity on a dedicated overnight EV tariff typically costs around 7p per kWh, which works out at roughly 2p a mile in an average EV. On the standard price cap rate of 26.32p per kWh (October to December 2026), it is around 7.5p a mile. A petrol car doing 45mpg with petrol at about 174p a litre costs roughly 17p a mile.

How you fuel the car	Typical cost	Approx. cost per mile
Home, overnight EV tariff	Around 7p/kWh	About 2p
Home, standard price cap rate	26.32p/kWh	About 7.5p
Public slow and fast chargers	54p/kWh average	About 16p
Public rapid and ultra-rapid	79p/kWh average	About 24p
Petrol car at 45mpg	About 174p a litre	About 17p

Less to go wrong mechanically. There is no clutch, cambelt, exhaust, DPF or oil to change. Regenerative braking means pads and discs often last much longer. Servicing is usually cheaper. See EV servicing, tyres and repair costs for the detail.

Clean air zones. EVs are exempt from ULEZ and clean air zone charges, which matters if you drive into London, Birmingham, Bristol or another charging city.

A nicer drive. EVs are quiet, smooth and quick away from the lights, and most are automatic.

What are the downsides?

Public charging is expensive. Zapmap’s price index put the average pay-as-you-go price at 54p/kWh on slow and fast chargers and 79p/kWh on rapid chargers in September 2026. If you rely on rapid chargers, an EV can cost more per mile than petrol. Public charging also carries 20% VAT, while home electricity is currently VAT-free until 31 March 2027. Read owning an EV without a home charger before you buy if you park on the street.

Insurance usually costs more. EVs are more expensive to repair, so premiums tend to be higher. MoneySuperMarket’s index put the average EV premium at around £562 in early 2026, against around £487 for petrol.

Tyres wear faster. EVs are heavy and have instant torque. Fleet data from Epyx found EV tyres were first replaced at an average of 17,985 miles, against 24,335 for petrol and diesel cars, and cost more.

Older EVs have short ranges. A ten-year-old Nissan Leaf or Renault Zoe may manage under 100 miles in winter. Some older cars also use the CHAdeMO rapid charging plug, which fewer new chargers support.

Car tax and pay-per-mile. EVs now pay standard car tax (£200 a year in 2026/27). From April 2028 they will also pay electric Vehicle Excise Duty at 3p a mile. For a driver covering 10,000 miles a year, that is about £300. Our guide to what pay-per-mile means for used EV buyers runs the numbers.

Is the battery a risk?

Less than most people think. Telematics firm Geotab’s 2025 study of more than 22,700 EVs found an average capacity loss of 2.3% a year, which leaves about 81.6% after eight years. UK battery tester Generational found a median state of health of 93.5% in four to five-year-old EVs and 85% in eight to nine-year-old cars.

Batteries are also covered by long warranties. Most manufacturers guarantee the battery for eight years or 100,000 miles, and will repair or replace it if capacity drops below around 70%. Many of these warranties pass to the next owner. Check how long is left; our guide to EV battery warranties on used cars explains what to look for.

The risk is not average degradation; it is the occasional car that has been abused, damaged or rapid-charged constantly. That is why a battery health check matters. An independent test is quick and cheap, and some dealers now include a certificate. See how to check the battery health of a used EV.

Who does a used EV suit?

A used EV is likely to work well if you:

Can charge at home or at work, ideally overnight on an EV tariff
Mostly drive under 150 to 200 miles a day
Drive into clean air zones or ULEZ
Want low, predictable running costs and less mechanical maintenance
Are happy to plan the occasional long journey around a rapid charging stop

Think twice if you:

Have no home or workplace charging and would rely on rapid chargers
Regularly tow a caravan or trailer, which cuts range sharply
Cover very long distances every day with little time to stop
Are looking at the very cheapest, oldest EVs and need a reliable winter range

If you are undecided, compare the options in used EV vs hybrid vs plug-in hybrid.

How to buy a used EV well

Get an independent battery health report, and check the remaining battery warranty.
Work through our used EV inspection checklist, including the cables.
Avoid older Renault Zoes and Nissan Leafs with a leased battery unless the numbers still work.
Get an insurance quote for the exact car before you commit.

Frequently asked questions

Is it worth buying a used electric car?

For most drivers who can charge at home, yes. Running costs are much lower than petrol and batteries are proving durable. It is less worthwhile if you would rely on public rapid chargers.

How many miles is too many for a used EV?

Mileage matters less than battery health. A high-mileage EV with a healthy battery report can be a better buy than a low-mileage car that has been rapid-charged constantly. Check the state of health and the remaining warranty.

Do used EV batteries need replacing?

Rarely. Average capacity loss is around 2.3% a year, and most batteries are covered for eight years or 100,000 miles against falling below about 70% capacity.

Are used electric cars expensive to insure?

They usually cost a little more than petrol equivalents because repairs are more expensive. Get a quote for the exact model before you buy.

Will used EV prices fall again?

Nobody can say for certain. Prices rose through 2026 as fuel costs pushed demand up, but supply from ex-lease cars is also growing. Buy a car that suits you at a fair price rather than trying to time the market.

Do electric cars pay road tax now?

Yes. EVs registered from April 2025 pay £10 in the first year, then the standard rate. All EVs now pay the standard rate, which is £200 a year in 2026/27.
