Some electric cars have suffered heavy depreciation because the used EV market went through a rapid correction, with supply increasing quickly while new-car prices, discounts and technology changed around it. That does not mean every EV depreciates badly, and the UK market in 2026 is already showing signs that the most dramatic phase of the adjustment may be easing.
Few subjects have damaged confidence in electric cars as effectively as depreciation. It is easy to find examples of three-year-old EVs that once cost £50,000 and can now be bought for a fraction of that price, but the conclusion that electric cars simply collapse in value because nobody wants them is much too simplistic.
What is car depreciation?
Depreciation is simply the difference between what a car was worth when it was new and what it is worth later. If a car costs £50,000 new and is worth £25,000 three years later, it has lost £25,000, or half of its original value.
Almost every mainstream new car depreciates, whether it is petrol, diesel, hybrid or electric. The useful question is whether a particular EV is likely to lose value faster than comparable alternatives and what is driving that change.
Why did used electric car values fall so sharply?
One of the biggest reasons was supply, because the early used EV market was relatively small and then expanded extremely quickly. Cars supplied through company-car schemes, salary sacrifice and leasing began returning to the market in much greater numbers, while buyer demand did not initially rise at the same pace.
Auto Trader reported in May 2023 that used EV supply had increased by 201% year-on-year while consumer demand rose by 44%, creating a major imbalance. Average used EV prices fell 18.6% year-on-year that month, which Auto Trader described as part of a market recalibration rather than evidence that electric cars had suddenly become unwanted.
Did new electric car discounts make depreciation worse?
Yes, because used values are always influenced by the price of a new equivalent. If a manufacturer cuts a new car by several thousand pounds, introduces a large deposit contribution or heavily discounts stock, a one or two-year-old version immediately has to compete with a cheaper new alternative.
Electric cars have been particularly exposed to this because manufacturers have been chasing market share while also working towards zero-emission sales targets. When new-car transaction prices move quickly, the used market usually has to adjust as well.
Does rapidly improving EV technology affect used values?
I think it does, because the pace of change in electric cars has been much more obvious than in many combustion models. A five-year-old petrol car might offer a broadly similar ownership experience to a newer equivalent, while an older EV may have noticeably slower charging, shorter range, less effective battery preconditioning or more basic route planning.
I see this first-hand when reviewing new electric cars, because charging performance that looked impressive a few years ago can now feel ordinary. That does not make the older car bad, but it can make it less desirable next to a newer model with better range, charging and efficiency for similar money.
Are buyers worried about used EV batteries?
Yes, and I think that uncertainty has also affected used values because many buyers still do not know how to assess battery condition. A petrol buyer roughly understands mileage, servicing, cambelts and clutches, while battery health can feel much less familiar.
The evidence is becoming more reassuring, with Geotab's 2026 analysis of more than 22,700 electric vehicles finding average battery degradation of around 2.3% per year. That does not mean every battery behaves identically, but it strongly suggests that modern EV packs usually lose capacity gradually rather than suddenly becoming unusable after a few years.
Could battery health certificates help used EV values?
Potentially, because buyers are more confident when they can see objective evidence about the condition of an expensive component. A four-year-old EV with verified battery health is easier to assess than an identical car where the buyer has to rely on assumptions.
I think battery-health reporting will eventually become as normal as service history and mileage in the used EV market. The more transparent that information becomes, the less room there is for fear to depress the value of otherwise healthy cars.
Are electric car prices still falling in 2026?
Not across the market as a whole, and this is where the story is becoming much more interesting. Auto Trader reported that average used EV prices returned to positive year-on-year growth in June 2026, while three-to-five-year-old electric cars were up 8.9% year-on-year and leaving retailers quickly.
The following month, Auto Trader said average used EV prices were up 3.3% year-on-year, its strongest annual growth for electric vehicles at that point. SMMT data also showed used battery-electric vehicle transactions rising sharply, which suggests demand is catching up with the much larger supply now entering the market.
Does that mean EV depreciation is no longer a problem?
No, because some electric cars will still depreciate heavily and some petrol cars will too. Residual values depend on the original list price, discounts, brand desirability, how many examples enter the used market at once, charging performance, range, reliability and the confidence buyers have in the manufacturer.
That is why I dislike sweeping statements about an “EV depreciation rate”. A heavily discounted £70,000 electric SUV can behave completely differently from a well-priced £25,000 EV with strong used demand, even though both use the same type of powertrain.
Are used electric cars becoming good value?
In many cases, exceptionally good value, because the steep depreciation suffered by some early owners has created attractive opportunities for second-hand buyers. A three or four-year-old EV can now offer a lot of performance, refinement and equipment for much less than its original price.
That does not mean I would buy purely because something looks cheap. I would still check battery condition where possible, remaining warranty, insurance cost, real-world range and charging performance, and my guide to understanding electric car range claims is a useful place to start.
Does leasing protect you from EV depreciation?
Leasing can reduce your direct exposure to future resale values because you do not own the car and normally return it at the end of the agreement. The finance company has already made assumptions about the vehicle's future value when setting the rentals, so you are not left trying to sell the car yourself if the used market moves sharply.
That does not make leasing automatically cheaper or better for everyone, because mileage limits, condition requirements and the lack of ownership at the end all matter. However, for fast-moving technology, being able to use a new car for a few years and hand it back can be attractive, which is something I have also discussed in my look at electric car lease pricing.
Would depreciation stop me buying an EV?
Not by itself, because depreciation is a financial question rather than an argument for or against electric cars. I drive electric and review a lot of EVs, but I would still look carefully at the price I was paying, how heavily the model was being discounted and what kind of demand I thought it would have in three or four years.
In some cases I would buy, in others I would lease, and there are plenty of electric cars where I think the smartest purchase may actually be a two or three-year-old used example after somebody else has absorbed the steepest part of the depreciation. If you are still deciding between powertrains, my EV vs plug-in hybrid guide explains the wider ownership differences.
Why do electric cars depreciate? My verdict
EV depreciation has been real, but the reasons are more complicated than the idea that nobody wants electric cars. Used supply grew rapidly, manufacturers changed new-car pricing, technology improved quickly and buyers were still learning how to judge batteries, charging and long-term ownership.
The 2026 market is already showing more stability, with stronger used demand and year-on-year price growth returning in parts of the sector. My advice is not to ask whether EVs depreciate, but whether the specific EV you are considering is sensibly priced today, desirable used and likely to remain useful to buyers several years from now.
