Selling an EV is different from petrol

For an electric car, the battery sets the value, the car depreciates faster in the first years and the charger counts. These are the factors that set selling an EV apart.

In short: why selling an EV is different

For an EV, battery health (SoH) is the main price factor, the car depreciates faster in the early years, and you can sell or take your home charger. The EU battery passport (2027) will make the battery's state accessible. Knowing these factors means selling smarter. Updated 2026-07-10.

The five factors

The battery sets the value

On a petrol car you look at the engine and mileage; on an EV, battery health (SoH) is the key price factor. Two identical cars with a different SoH can differ by hundreds to thousands of pounds. Get the battery checked and attach the report.

Faster depreciation in the early years

EVs usually depreciate faster in the first years than petrol cars, partly due to rapid model and battery-tech renewal. It then levels off. Knowing the residual-value curve helps you pick a better time to sell.

Your home charger counts

Are you selling your home charger with the car or taking it with you? A professionally installed charger can be a selling point. Make clear what's included and what isn't.

EU battery passport from 2027

The EU battery passport becomes mandatory on 18 February 2027 (Battery Regulation 2023/1542), making the SoH accessible. A SoH already proven today gets ahead of it and builds trust.

Technology dates faster

Charging speed, range and software updates move quickly. An EV a few years old can feel technically 'older' than a same-age petrol car. Transparency about version, range and charging speed builds confidence.

The battery is the most expensive component of an electric car. The State of Health (SoH) shows how much capacity remains and drives both the range and the residual value. A proven, healthy SoH earns a higher price and more trust.
You can, but it's a choice. A professionally installed charger can be a selling point for the buyer. Make clear whether the charger (and cables) is included, and factor it into the price.
There's no specific UK rule requiring you to state the SoH. For private sales it's 'buyer beware', but you must not actively misrepresent a known fault; for dealers the Consumer Rights Act applies. From 18 February 2027 the EU battery passport will make the SoH accessible. Transparency is a selling point either way.
