PARLIAMENTARY WRITTEN QUESTION
(13 February 2025)

To ask the Secretary of State for Transport, if she will make an assessment of the potential merits of implementing a standardised battery health certification scheme for second-hand electric vehicles.

Asked by:
Dr Scott Arthur (Labour)

The Department for Transport has worked with the United Nations Economic Commission for Europe (UNECE) to develop a Global Technical Regulation on electric vehicle batteries (GTR 22). If implemented, the regulation would set standards for the lifespan of a battery and its minimum durability. It will also ensure that information about electric vehicle batteries is easily accessible, accurate and comparable. The Government is currently considering options for the implementation of GTR 22 battery regulations in the UK.

In the meantime, the Zero Emission Vehicle (ZEV) Mandate requires all new electric vehicles to be sold with a warranty that includes battery replacement if capacity falls below 70% in the first 8 years or 100,000 miles, whichever is sooner.
