Used EV Prices Are Rising Again: What August's Data Means for You

Used electric cars spent the best part of three and a half years losing value, and that run is over. Auto Trader's August market data, published on 8 September, puts the average asking price of a used electric car at £25,095, up 3.8% on a year earlier and 0.5% on July. It is the third consecutive month of annual price growth for the segment, and the strongest price performance of any fuel type in the market.

For anyone who has been circling an electric car on a dealer website, waiting for the price to fall one more time, that wait now costs money.

The turn has become a trend

The first flicker came in June, when used EV values recorded their first positive annual reading since December 2022, a milestone we covered in our look at the record second quarter. May had been flat after forty consecutive months of decline. June turned positive. July went further. August made it three in a row.

The detail matters more than the headline. Underneath the £25,095 average, the strongest movement is in cars aged three to five years, where like-for-like prices rose 9.4% year on year and 1.4% on July to an average of £20,351. This is the cohort that carries the first wave of electric cars sold on company schemes and personal contracts, the ones now coming back to dealers with sensible mileages and battery warranties that still have years left to run.

It is also the bracket where the electric-versus-petrol arithmetic tilted first. In July the average advertised price of a three-to-five-year-old electric car was £20,037 against £18,731 for the petrol equivalent, a gap of about £1,300, and Indicata's analysis of more than 14 million adverts has already shown used electric cars undercutting their petrol and diesel counterparts on average, which we picked apart in our piece on the flipped price gap.

The fastest-moving stock on the forecourt

Price growth on this scale only happens when demand outruns supply, and the speed data says the same thing. Autotrader's separate August rankings release found electric to be the fastest-selling fuel type for the fourth month running, with six of August's ten fastest-selling used models fully electric. MG, Tesla and Polestar share seven of those ten places between them, which tells you where the volume of keenly priced three-year-old stock sits.

According to the Retail Price Index, the average used car sold in 30 days in August, one day quicker than July and unchanged on last year. In Autotrader's fastest-selling snapshot for August, electric cars averaged 25 days to turn against 30 for the market as a whole, with the three-to-five-year-old electric cohort the quickest segment at 20 days. Dealers are not sitting on electric stock and hoping; it is leaving the forecourt at or ahead of the market's own pace.

The same release records that used car transactions rose 2.6% year on year in August, with franchised dealers, independents and supermarkets all reporting growth in the same month for the first time in 2026. An improvement spread across every kind of seller is a healthier signal than a spike in one channel.

What is holding prices up

Two things are pushing in the same direction. Demand has firmed because the running-cost argument is now familiar and documented rather than theoretical, and because a fuel price shock earlier this year turned attention to what a car costs to run rather than only what it costs to buy. Supply has tightened because the used electric pool is still small relative to the appetite for it. Auto Trader's own summary of the month points to buyer appetite meeting improving confidence about electric cars in the second-hand market.

There is a counter-current worth understanding. Cars aged one to three years fell 1.8% year on year in August, the clear source of softness in the overall market, and the reason is competition from new cars. Aggressive offers on new electric models, plus the Electric Car Grant on eligible ones, pull prices down at the nearly-new end. The three-to-five-year bracket does not face that pressure in the same way, because those cars are past the point where a new-car discount is the obvious alternative.

The wider market is stable rather than inflationary. The average used car asking price was £17,131 in August, with like-for-like prices 0.1% lower than a year earlier and 0.4% down on July, which Auto Trader describes as normal August seasonality. Softer wholesale values have not been passed on at the forecourt. Older cars did well too, with ten-to-fifteen-year-old stock up 6.9% to an average of £7,183, another sign that buyers are shopping to a budget and finding value where it exists.

What it means if you are buying

The practical read for a buyer is that the deepest discounts on used electric cars have already been taken, and the best cars are moving quickly. Expect less room to negotiate on a well-priced three-year-old electric car than you would have had in the spring, and expect it to be gone if you think about it for a fortnight.

That is not the same as saying the value has gone. A three-to-five-year-old electric car at around £20,000, with a battery warranty still running and home charging at a fraction of the cost of petrol, remains one of the better-value ways to run a car in Britain this autumn. The work has shifted from finding a bargain to choosing well. Battery health checks, service history, tyre and software condition, and a realistic look at where you will charge all matter more when the market is tight than when it is drowning in stock, and our used EV buying checklist remains the place to start.

September's plate change is worth watching in the background. The 76 plate pushed a large volume of new cars out of showrooms this month, and the part-exchanges that funded them will arrive in the used pool over the next few weeks, which usually adds supply at the nearly-new end. That will not do much for three-to-five-year-old stock, but it should keep pressure off prices on younger cars.

What it means if you are selling

If you own a three-to-five-year-old electric car, the market has turned in your favour for the first time since you bought it. It is one of the fastest-selling segments on the forecourt, which is a lever in a part-exchange conversation, and the recovery in used values feeds directly into residual values and therefore into monthly PCP and lease costs on the next car. We went through that mechanism in our explanation of EV residuals.

The averages do hide a lot, so check your own model rather than the headline. Among electric cars, the Renault Zoe led annual price growth at 11.9% to an average of £8,895, followed by the Skoda Enyaq at 10.5% to £26,216, the MG5 at 10.4% to £11,410 and the Kia Niro at 10.3% to £18,034. Moving the other way, the Nissan Ariya fell 17.3%, the BMW i5 15.3% and the Audi A6 e-tron Avant 24.4%. Individual model risk has not disappeared, and newer, larger electric cars are still finding their level.

The honest read

Three months of rising prices is a real change of direction, and it deserves to be reported as one. It is also worth keeping the base in view: used electric values fell for more than three years, and a few months of growth has not undone that. What August shows is a market finding its floor with buyers underneath it rather than distressed sellers on top, which is the version of this market everyone said would eventually arrive. For buyers, the window is narrower than it was in May. For sellers, it has opened. Neither side should read a single quarter as a forecast.
