Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to Answer of 19th March 2026 to Question 120277, Electric Vehicles: Costs, what assessment she has made of the impact of battery degradation on the used electric vehicle value.

The latest data on electric vehicle (EV) battery degradation suggests the majority of EV batteries comfortably exceed warranty thresholds. The Zero Emission Vehicle Mandate and the Government’s Electric Car Grant require manufacturers to provide battery warranties of at least eight years or 100,000 miles, ensuring EVs and their batteries have long useable lives, including in the second-hand market.

The Government recognises public perceptions around battery health have impacted consumer sentiment relating to used EVs. To strengthen consumer confidence, particularly in second-hand EV purchases, the Government is exploring options to adopt regulations which would provide consumers with standardised, consumer accessible information on EV batteries’ state of health.
