⚡ The short version
Prime Minister Burnham meets European Commission President Ursula von der Leyen on Tuesday 22 September to try to settle the EU–UK row over car rules. The sticking point is not Chinese cars: it is the battery “rules of origin” in the EU–UK Trade and Cooperation Agreement, which tighten on 1 January 2027. Europe’s carmakers say 82% of the electric cars and vans the EU expects to send to Britain next year — around 426,000 vehicles — would fail those rules and attract the 10% customs duty, a bill of €1.47 billion in 2027 alone. If the two sides cannot agree, that cost ends up on British price lists.
Two arguments about cars are running through European trade policy at the same time, and only one of them is about China. The one that reaches UK price lists fastest is the quieter of the two: the battery rules of origin in the EU–UK Trade and Cooperation Agreement, which tighten on 1 January 2027.
What is happening today
The Times reported on Monday that UK Prime Minister Burnham will meet European Commission President Ursula von der Leyen on Tuesday 22 September, with the dispute over EU car rules at the top of the agenda.
The row concerns the “rules of origin” test in the Trade and Cooperation Agreement — the calculation that decides whether a car built on one side of the Channel can be sold on the other without paying the 10% customs duty that applies to goods that do not qualify. Since Brexit, electric vehicles and batteries have been the hardest part of that calculation, because European battery supply chains have scaled more slowly than the rules assumed.
The threshold that bites from 1 January 2027
Until the end of this year, the agreement accepts battery-pack assembly as the test of where a battery comes from. From 1 January 2027 that stops, and the rules start counting cells and materials instead.
| Requirement from 1 January 2027 | Share that must originate in the UK or EU |
|---|---|
| Vehicle value | 55% |
| Battery pack | 70% |
| Battery cells | 65% |
These thresholds were originally due in 2024. They were pushed back to the end of 2026 after manufacturers warned that European battery production was not scaling fast enough — and that extension was presented as a one-off.
What Europe’s carmakers are telling Brussels
In a letter dated 17 September 2026, the European Automobile Manufacturers’ Association (ACEA) told the European Commission and member states that, on the industry’s own numbers, the new rules cannot be met on that timetable.
ACEA expects the EU to export 520,000 electric cars and vans to the UK in 2027. It estimates that 82% of them — roughly 426,000 vehicles, worth about €17.9 billion — would fall outside the thresholds and become liable for the 10% duty. The association puts the tariff bill at €1.47 billion in 2027 alone.
Its proposed fix is a staircase rather than another blanket delay: keep the existing pack-assembly rules until the end of 2029, move to stricter cell-localisation requirements from 2030, and add cathode-material requirements from 2032, with a longer timeline for heavy trucks. ACEA’s framing is that the direction of travel is not in dispute — “the question is not whether they will be able to comply, but when”.
The UK side has signalled it is open to talking. That is not surprising. A 10% duty on EU-built electric cars raises prices for British buyers without moving a single factory to Britain.
Which cars are actually exposed
ACEA names no manufacturers and publishes no per-model verdicts, so nobody should read a specific badge into the 82% figure. But the exposure is structural rather than theoretical. Every electric car built in an EU plant and shipped to Britain sits inside it — and so does the UK’s best-selling electric car, the Tesla Model Y, which is built at Giga Berlin.
Put the numbers together and the scale is clear: on the EU’s own forecast, more than half a million EU-built electric cars and vans are heading for British driveways in 2027. A 10% duty on that volume is the kind of change that shows up on a price list rather than in a policy document.
It also cuts in the opposite direction to the tariff argument Britain settled earlier this month. Ministers have ruled out matching the EU’s duties on Chinese-built cars; this dispute would tax European production instead. Our analysis of why Britain refuses to match EU tariffs on Chinese cars sets out that side of the story.
The second row: “Made in Europe”
Rules of origin are not the only automotive question on the table. Britain is also pressing Brussels over the EU’s Industrial Accelerator Act, proposed in March, which uses public procurement and public support schemes to drive demand for European-made and lower-carbon goods.
UK government analysis suggests British content would generally be treated as equivalent to EU origin under several of those measures, because of the existing trading relationship. Automotive provisions are the exception: the government’s explanatory memorandum warns that some UK-made automotive components could fail to count towards the required thresholds if exclusions in the Commission’s original wording survive into the final law.
Chancellor John Healey raised the issue with European counterparts in Dublin in September, with British automotive exports into European markets worth around £15 billion a year. The legislation still has to pass the European Parliament and Council, and much of the detail will be set later in delegated measures — so the calculation that decides whether a British-made component counts is still being negotiated.
Meanwhile, Brussels is softening 2035
The same week brought a significant change from Brussels itself: the European Commission’s plan to require 100% zero-emission new car sales by 2035 has been revised to a 90% target, with the remaining 10% made up of conventional or hybrid cars. Carmakers would be expected to use low-carbon steel made in the EU, with more biofuels and e-fuels to compensate for the extra emissions.
The green transport group Transport & Environment warned the UK not to follow suit by weakening its own ZEV mandate — a live question here, because the government’s ZEV mandate review closes at 11:59pm on 23 October 2026.
Separately, Brussels wants China to “voluntarily” cap hybrid car exports at around 15% of the EU market, down from more than a third today. Beijing has rejected the idea as inconsistent with World Trade Organization rules, and Germany has shifted to support duties on Chinese plug-in hybrids. Britain, by contrast, has refused to match EU duties on Chinese-built cars — part of a wider split traced in our report on Chinese EV exports to the EU.
What it means for UK EV buyers
Nothing changes today. The deadline is 1 January 2027, and any change has to clear the European Commission and EU member states before it can be agreed with London.
The risk is a 10% price rise on EU-built cars, not on all EVs. If the rules bite, a manufacturer either absorbs the duty or passes it on. On a £40,000 electric car, 10% is £4,000 — more than the £3,750 Electric Car Grant is worth on the models that qualify for it.
Watch the used market too. A duty on new EU-built electric cars lifts the value of equivalent used cars already in Britain, because it raises the price of the alternative.
Don’t buy on a rumour. Both sides have signalled they want a deal, and these rules have already been deferred once. But the calendar is short: any change has to be agreed before January, and the industry’s own compliance timeline runs to the end of the decade.
The bottom line
The row Burnham and von der Leyen are trying to settle on Tuesday is not really about tariffs as a weapon. It is about whether the EU–UK trade agreement’s own rules can be met by the industry that has to live with them. Europe’s carmakers say they cannot, yet; Britain’s carmakers and buyers have every reason to want the flexibility extended again. If it is not, the first place the 10% shows up is the price of an electric car in a British showroom — and for once, the tariff would land on European factories rather than Chinese ones.
