The Department for Transport has worked with the United Nations Economic Commission for Europe to develop a Global Technical Regulation on electric vehicle batteries (GTR No.22). If implemented, the regulation would set standards on the lifespan of a battery and its minimum durability. It would also ensure that information about electric vehicle batteries is easily accessible, accurate and comparable. The Government is currently analysing options for the implementation of GTR No.22 regulations in the UK and aims to consult on these plans later this year.

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.
