Used EV dealers and buyers are set to gain more consistent information about battery condition after the Government confirmed that Great Britain will adopt Euro 7 standards.
The regulations introduce minimum battery durability requirements for new electric cars and plug-in hybrids alongside onboard systems that monitor battery state of health.
Euro 7 will become mandatory for new cars and vans registered in Great Britain from November 29, 2027. Small-volume manufacturers will have until July 1, 2030.
Minimum battery life standards
Under Euro 7, electric and plug-in hybrid passenger-car batteries must retain at least 80% of their original capacity for five years or 100,000km, around 62,000 miles, whichever comes first.
The minimum falls to 72% for vehicles aged between five and eight years or with between 100,000km and 160,000km, around 99,400 miles. For electric and plug-in hybrid vans, the corresponding thresholds are 75% and 67%.
Vehicles will also be required to carry battery state-of-health monitors, creating a common basis for comparing battery condition across different manufacturers, models and powertrains.
The change could help used EV dealers demonstrate battery condition more clearly and give consumers greater confidence when comparing used electric vehicles.
BVRLA backs comparable data
Toby Poston, chief executive of the BVRLA, said: “We welcome today’s Euro 7 battery health standards. They’re an important step in building trust in electric vehicles, aligning the rules with the global GTR 22 framework is the right approach. It means one consistent benchmark for battery durability across manufacturers, and across different makes and models, so buyers, dealers and leasing companies can finally compare like with like.
“Just as importantly, battery health data should become much easier to access, whether that’s on the dashboard or through the OBD port. That transparency is exactly what the used market needs. The used market has long been a focus for the BVRLA, because that’s where most drivers will make the switch to electric. Our EV Retail Ready programme is designed to support used dealers; standards like these strengthen the market further.
“The message to consumers is simple. Used battery electric vehicles are a smart, affordable choice, and people should buy them with confidence.”
The Department for Transport said Euro 7 would be implemented by accepting EU and equivalent United Nations Economic Commission for Europe type approvals, avoiding separate testing specifically for Great Britain.
The wider regulations will also introduce limits on particulate emissions from brake wear and tyre abrasion, alongside strengthened monitoring of vehicle emissions over their working lives.
A statutory instrument will now be laid to implement the new minimum standard. Separate implementation dates for trucks, buses and coaches will be subject to a further consultation.
