Euro 7 confirmed for Great Britain: EV battery durability rules from 29 November 2027

Every new car and van registered in Great Britain from 29 November 2027 will have to meet the Euro 7 emission standard, the Department for Transport (DfT) confirmed on 27 October 2026. For electric cars, the important part is not the exhaust rules but the battery ones: Euro 7 brings minimum battery durability standards and battery health monitors. In practice, that means EVs registered from late 2027 should be easier to judge when they reach the used market in the 2030s. It changes nothing for the EVs on sale or on the road today.

The decision is set out in the government response to its consultation on updating the minimum emission standard for new road vehicles. Here is what has been decided, what is still open, and what it means if you plan to buy a used EV.

What has the government announced?

The DfT says it has “decided to proceed with updating the minimum emission standard for new road vehicles in Great Britain to Euro 7”. It will lay a statutory instrument under the Product Regulation and Metrology Act 2025 to apply Euro 7 to all new unlimited volume light duty registrations, which means cars and vans from mainstream manufacturers.

What	Date	Status
Consultation opened	13 April 2026	Closed 25 May 2026, 67 responses
Government response published	27 October 2026	Statutory instrument to follow
New car and van types	Proposed 29 November 2026	Dropped: no mandatory GB date
All new cars and vans registered (unlimited volume makers)	29 November 2027	Kept
All new cars and vans registered (small volume makers)	1 July 2030	Kept
Trucks, buses and coaches	Not set	Further consultation to follow

The government will implement Euro 7 by accepting EU and equivalent UNECE type approvals as proof of compliance, rather than running a separate British test regime. Until the statutory instrument is in force, the response says the Vehicle Certification Agency “will not be able to accept EU Euro 7 type approvals”, so manufacturers are advised to use UN Regulation approvals in the meantime.

Of the 67 responses, 53 came from organisations and 14 from private individuals.

What does Euro 7 mean for electric cars?

Euro 7 is the first emission standard that deals directly with electric cars. The DfT’s April 2026 consultation document listed three changes that matter to EV drivers:

• Battery durability: “Battery durability requirements are introduced for EVs and PHEVs, including minimum capacity retention thresholds.” Plug-in hybrids are covered as well as pure electric cars.
• Battery health monitors: “Euro 7 also requires vehicles to be fitted with accurate, accessible and comparable battery health monitors.”
• Brakes and tyres: Euro 7 “introduces new requirements to limit PM emissions from brake wear and tyre abrasion”. Electric cars produce no exhaust, but they do wear brakes and tyres.

The government response itself does not restate the battery measures in detail. It records that “respondents welcomed the proposed introduction of electric vehicle (EV) battery durability requirements”, and it confirms that Euro 7 is going ahead on the proposed registration dates.

EV Fleet World reports that the battery standards are aligned with the UN’s GTR 22 framework and that battery degradation data should be readable on the dashboard or through the on-board diagnostics (OBD) port. Those details come from the trade report rather than the GOV.UK pages we read.

What battery health will cars have to keep?

The GB documents do not give figures. They say only that there will be “minimum capacity retention thresholds”. Because the UK plans to accept EU approvals, the EU’s numbers are the best guide, but they are the EU’s figures and have not been published as GB law.

According to the European Parliament, the December 2023 Euro 7 deal set these minimums:

Vehicle	Up to 5 years or 100,000 km (about 62,000 miles)	Up to 8 years or 160,000 km (about 99,000 miles)
Cars (electric and hybrid)	80%	72%
Vans	75%	67%

The same deal set a brake particle limit of 3mg per km for pure electric vehicles, against 7mg per km for most petrol, diesel, hybrid and fuel cell vehicles.

These thresholds are a standard the car has to be approved against. They are not a warranty that a dealer or manufacturer owes you if your car falls short, and they do not replace the battery warranty that comes with the car. Our guide to EV warranties explains what those normally cover.

What would 80% and 72% mean in miles?

To put the EU figures into practical terms, here is an illustration. It is our own calculation from stated inputs, not a figure for any real car:

• Battery: 60kWh of usable capacity when new.
• Efficiency: 3.5 miles per kWh, a reasonable year-round figure for a mid-sized electric hatchback or small SUV.
• Assumption: range falls in line with capacity, which is a simplification, because the EU rules measure certified energy and real range also depends on weather and speed.

Battery condition	Capacity	Estimated range
New	60kWh	About 210 miles
EU minimum at 5 years or 100,000 km (80%)	48kWh	About 168 miles
EU minimum at 8 years or 160,000 km (72%)	43.2kWh	About 151 miles

So at the eight-year floor, a car that did 210 miles when new would still manage about 150 miles on a charge. Most batteries do far better than that. Independent tests from Aviloo, which we covered in our Aviloo battery study report, found 16 of 20 popular models keeping a median 90% or more at 150,000km (about 93,000 miles). Our guide on how much battery degradation is normal has more detail. The value of Euro 7 is less about the floor and more about every car reporting its health in a comparable way.

Does this apply to EVs already on the road?

No. Euro 7 applies to new vehicles registered from 29 November 2027. According to the consultation document, cars approved to Euro 6d or Euro 6e can still be registered until 28 November 2027, or until 30 June 2030 for small volume manufacturers. Every EV on the road now, and every one registered before the cut-off, sits outside the new rules.

Some cars registered before November 2027 may already be built to Euro 7, because manufacturers selling in the EU will be approving models to it. But you cannot assume that, and there is no GB requirement for a pre-2027 car to have a standard battery health monitor.

What does it mean for buying a used EV in 2030 and beyond?

The benefit arrives slowly, because it only applies to new cars. A rough timeline for a car first registered in December 2027:

• 2029 to 2031: it starts appearing as a two to three year old used car, often from leasing and company fleets.
• December 2032: it reaches the five-year point, when the EU car threshold is 80%.
• December 2035: it reaches the eight-year point, when the EU car threshold is 72%.

For buyers in the early 2030s, the used market will be a mix. Cars registered from November 2027 should carry a battery health monitor that reads in a common way across brands. Older cars will still rely on each manufacturer’s own display, an OBD2 reader or an independent test.

Toby Poston, chief executive of the BVRLA, the leasing industry body, told EV Fleet World it means “one consistent benchmark for battery durability across manufacturers” and that buyers, dealers and leasing companies “can finally compare like with like”.

That matters because more used EVs are being financed and leased, not just bought outright. BVRLA figures quoted by Electrical Times show used EV personal contract hire up 484% and used EV salary sacrifice up 474% over the past year. Leasing companies set monthly prices on what they expect a car to be worth when it comes back, and uncertainty about the battery pushes those prices up. A common battery health reading should, over time, make used EV values more predictable for lenders, dealers and private buyers alike.

Until then, how do you check a used EV battery?

For any used EV you buy before the 2030s, nothing changes. There is still no legal requirement for a battery health certificate, for dealers or private sellers. The practical steps are:

1. Ask for a battery health certificate from the dealer, or pay for an independent one. Our guide to getting a battery health certificate explains who issues them and what they should include.
2. Check it yourself if you can. Our guide to checking an electric car battery before buying used covers test drives and in-car displays, and our explainer on OBD2 adapters for electric cars covers the dongle and app route.
3. Get it in writing. A battery health figure written into the sale paperwork is what counts if there is a dispute later, as we explain in our report on used EV battery disputes.
4. Check the remaining battery warranty, including its mileage limit and the health percentage it guarantees.

Will the MOT check battery health?

Not yet. The government response notes that “a number of respondents called for further measures, including battery durability checks at the MOT and over-the-air access to battery durability data for third parties”. It does not commit to either.

Pressure for wider checks is building. In August 2026, Electrifying.com, New AutoMotive and BatteryIQ called for mandatory battery state of health certificates for all dealer-sold used EVs, according to Electrical Times. A survey of more than 13,000 UK drivers by Electrifying.com and the AA found only 3% felt confident buying a used EV, while 38% said an independent battery health certificate would increase their confidence.

What happens next?

Several things are still to come:

• The statutory instrument. The DfT will lay it to make Euro 7 law in Great Britain. No date has been given.
• Heavy vehicles. A further consultation will set dates for trucks, buses and coaches.
• Northern Ireland. The government’s aim is alignment with Northern Ireland and the EU from the date that applies to all new registrations. Respondents asked for early clarity on how on-board monitoring rules will apply to cars registered there.
• Replacement brakes. Replacement brakes fitted to Euro 7 cars will not initially have to meet the new brake wear limits, the response says.

Our view

This is a quiet but useful change for anyone who will buy a used electric car in the 2030s. A standard battery health readout on every new EV from November 2027, backed by minimum durability standards, should make used EVs far easier to compare and price. But it does nothing for the cars on sale now. If you are buying a used EV this year or next, a written battery health certificate is still the best protection you have, and it is worth insisting on one.
