What Used Electric Car Values Up to 28 Percent Higher Mean for Every Buyer

• Trade values of the ten three-year-old electric cars with the biggest rises, each with 30,000 miles, climbed between 15.4 and 28.3 percent in six months, in Solera CAP HPI data published by Auto Express.
• The Tesla Model 3 gained £3,813 to reach £22,188 and the Polestar 2 gained £3,765, as diesel hit a record average of 200.01p a litre on 2 October and electric car enquiries on a car-buying platform rose 28 percent.
• The government plans a 3p a mile charge on electric cars from 1 April 2028, and every owner with a PCP agreement can check today whether the car is worth more than the settlement figure.

Six Months Ago a Three-Year-Old Tesla Model 3 Traded at £18,375 and Now It Trades at £22,188

A dealer now pays between £1,668 and £3,813 more for a three-year-old electric car than six months ago, and the retail price a buyer sees has to sit above that figure. Solera CAP HPI, the valuations specialist that measures trade values for cars of three years old with 30,000 miles on the clock, recorded rises of between 15.4 and 28.3 percent across the ten models with the biggest gains. The MINI Cooper Electric led the percentage table, up £2,805 from £9,905 to £12,710. The Tesla Model 3 led the pound table, up £3,813.

These are trade values, the price a dealer pays for a car, so every figure here sits below what a forecourt asks. They show the direction of the market and the size of the move. The valuations desk reads them as a rebound with limits. Chris Plumb, head of valuations at Solera CAP HPI, said: “What we’re really seeing is a recovery from previously depressed positions rather than a market running away with itself. In many cases these vehicles still represent excellent value for money and are becoming increasingly attractive to used car buyers as confidence in EVs continues to improve.”

The Ten Models That Gained Most, and What Each Added

The Polestar 2 (2019 onwards) went from £18,057 to £21,822, a gain of £3,765 or 20.9 percent. The Cupra Born (2021 onwards) went from £15,475 to £18,555, up £3,080 or 19.9 percent. The Tesla Model 3, Polestar 2 and Cupra Born all gained around 20 percent, and the Subaru Solterra (2022 onwards) added 19.3 percent, rising £2,575 from £13,350 to £15,925.

The cheaper end of the table moved by almost as much in percentage terms. The MG5 (2020 to 2025) rose 18.9 percent, from £9,025 to £10,731. The Kia e-Niro (2018 to 2023) rose 18.4 percent, from £12,867 to £15,233. The Volkswagen ID.3 (2020 to 2024) rose 17.6 percent, from £12,648 to £14,870, the Peugeot E-208 (2019 onwards) rose 17.4 percent, from £9,593 to £11,262, and the MG4 (2022 onwards) rose 15.4 percent, from £11,355 to £13,110.

The pound rise ran from £1,668 on the Peugeot E-208 to £3,813 on the Tesla Model 3.

The rebound follows a hard year. Cap HPI valuations published in early October showed used electric cars losing value fast, with the Nissan e-NV200 down 29 percent in a single year.

Diesel at £2 a Litre Arrives as Electric Car Enquiries Climb

The RAC recorded the average price of a litre of diesel at a record 200.01p on 2 October, above the previous high of 199.09p set in June 2022. Unleaded averaged 174.71p. A 55-litre tank of diesel cost £110.01, which is £31.70 more than on 28 February, the start of the US and Iran conflict, and a tank of petrol cost £96.09, which is £23.03 more.

Simon Williams, RAC head of policy, put the annual cost in miles: “For an average 45mpg diesel car, the cost works out at an extraordinary 20p per mile, so a driver covering 10,000 miles a year is now spending £2,020 on fuel a year.” A driver at that mileage who moves to an electric car swaps that bill for a home charging bill, with the planned 3p a mile charge 17 months away.

Buyers have responded. A car-buying platform recorded a 28 percent rise in electric car enquiries, meaning requests for quotes or test drives, between March and the end of September 2026. Diesel car enquiries on the same platform fell 33 percent. The figures do not split new from used, and they do not show how many enquiries ended in a purchase.

If You Are Buying, Check These Four Things Before You Pay More

Start with the price gap. Compare the asking price of the car with the trade values above and with two or three similar cars for sale, and ask the seller to explain any difference. Plumb gave three reference points: “It’s important to look beyond the percentages. Even after those increases, many of these vehicles remain relatively affordable. The MINI Electric is now around £12,700, the Peugeot E-208 sits at around £11,300 and the MG4 just over £13,000.”

Next, read the mileage. The MOT history on GOV.UK shows mileage readings for most cars, and the government intends to use that same MOT data to check the mileage declared under the new charge. Look for readings that rise by a steady amount from one test to the next.

Third, ask for a battery health report and the full service history, and check the V5C matches the seller and the car. Fourth, work out the running cost against the fuel it replaces. A 45mpg diesel car covering 10,000 miles costs £2,020 a year in fuel at the RAC’s October price. An electric car at the same mileage would carry a £300 mileage charge from April 2028 under the plan on top of whatever home or public charging costs.

If You Own One, Find Out What It Is Worth Before You Decide Anything

A three-year-old Tesla Model 3 owner has £3,813 more in trade value than six months ago, and a MINI Cooper Electric owner has £2,805. Whether that turns into money depends on how the car was bought.

On a PCP agreement, the finance company sets a guaranteed minimum future value for the car at the end of the term. A driver can hand the car back, pay the optional final payment to keep it, or part-exchange it. If the car is worth more than the settlement figure, the difference is equity, and a dealer can use it as the deposit on the next car. Ask the lender for a settlement figure and compare it with at least three valuations, from a dealer, an online buying service and a trade guide. The reverse problem, owing more than the car is worth, hit roughly 30 percent of new-vehicle HP and PCP trade-ins in early 2026 on Cap HPI and Finance and Leasing Association figures, which makes positive equity worth confirming before any deal is signed.

A private sale or a dealer part-exchange both start with the same paperwork. Have the V5C, service history, both keys, the charging cable and a battery health report ready, and take the highest of three offers rather than the first. Plumb describes a recovery from depressed levels, so a seller has no promise of further rises to wait for.

The 3p a Mile Charge Planned for April 2028

HM Revenue and Customs sets out in its policy paper, updated 28 October 2026, a mileage-based charge from 1 April 2028 of 3 pence a mile for battery electric and hydrogen cars and 1.5 pence a mile for plug-in hybrids. The charge is not yet law: the paper says primary legislation will be introduced. The rate rises in line with Consumer Prices Inflation from 2029 to 2030. The paper expects the charge to affect around 5.6 million vehicles in the 2028 to 2029 financial year, and drivers pay it when they first renew vehicle tax after April 2028.

The arithmetic for a used buyer is simple. At 8,000 miles a year the charge would be £240, at 10,000 miles £300 and at 12,000 miles £360. Under the plan an owner gives the DVLA an odometer reading and an estimate of the miles ahead when renewing vehicle tax, and pays upfront or spreads the cost across the year, with a reconciliation when the year-end reading is in. The full mechanics are covered in how the £240 mileage tax works.

A buyer who pays today’s price for a Model 3 would face a charge that starts 17 months from now, if the plan becomes law as published. Set the budget on the price of the car, the charging cost and the mileage charge together, and use the MOT mileage history on GOV.UK to see how far the previous owner drove.
