Three EV organisations have called on the Government to introduce a nationally recognised battery State of Health certificate for dealer-sold used EVs.
Electrifying.com, New AutoMotive and BatteryIQ argue that buyers should receive the same transparency about an EV’s battery condition as expected from an MOT certificate, service history or mileage record when purchasing an ICE car.
Research conducted by Electrifying.com and the AA found that just 3% of UK drivers felt very confident about buying a used EV, while 38% said an independently verified battery certificate would increase their confidence.
The introduction of a certificate could make used EVs easier to sell, as well as strengthen residual values and reward vehicles that have retained battery performance.
The three organisations want the government to collaborate with manufacturers, retailers and testing providers to establish a standard that can be applied consistently across the used EV market.
In response, the Department for Transport have stated that they are working on introducing new rules to provide clearer and more consistent battery health information to support more UK drivers considering the switch to electric cars.
AX’s 2025 report, EV Battery Longevity & Post-Accident Outcomes, found that EVs still face a number of misconceptions by the public, including battery health, highlighting the importance of introducing legislation that focus on the transparency of EV battery health and how clarity will build trust when it comes to purchasing second-hand EVs.
