UK dealers selling all-electric cars made in Europe could face higher prices and reduced supply when tougher EU-UK battery sourcing rules take effect in January 2027.
The European Automobile Manufacturers’ Association (ACEA) is warning that 82% of the 520,000 electric cars and vans expected to be exported from the EU to Britain next year will not comply with the incoming rules of origin.
In a letter to EU leaders, ACEA has asked the European Commission and EU member states to consider a temporary change to the battery rules of origin in the EU-UK Trade and Cooperation Agreement (TCA), warning that the requirements due to apply from January 2027 cannot be met by European car manufacturers.
It warns that the TCA would expose approximately 426,000 vehicles to a 10% customs duty. The affected exports are expected to be worth €17.9 billion, with a potential tariff bill of €1.47bn during 2027 alone.
That equates to an average customs cost of around £3,000 although the amount would vary according to each model’s import value.
Manufacturers would then have to decide whether to absorb the duty, pass it into retail prices, reduce incentives or alter the vehicles allocated to the UK.
Each option could affect dealer margins, monthly payments and the competitiveness of European EVs.
How battery rules trigger tariffs
The TCA allows qualifying vehicles to move between the two markets without tariffs, but only when they contain sufficient material originating in Britain or the EU.
From January 1, 2027, at least 55% of an electric vehicle’s value must originate in the UK or EU. Battery packs must meet a 70% originating-content requirement, while the threshold for battery cells will be 65%.
Vehicles which cannot demonstrate compliance will face the standard 10% tariff when crossing between the two markets.
The stricter requirements were originally due to begin in 2024 but were postponed until the end of 2026 after manufacturers warned that European battery supply chains were not developing quickly enough.
That extension was presented as a one-off measure and included a mechanism intended to prevent further changes before 2032.
Another adjustment would therefore require political agreement between the EU and UK and may prove more legally complicated than the earlier delay.
For dealers, the risk goes beyond a straightforward increase in list prices. Manufacturers could protect pricing by accepting lower margins, but this may reduce the money available for deposit contributions, subsidised finance and tactical support.
Brands could also prioritise models which comply with the rules or redirect non-compliant production towards markets outside the UK. This could change lead times and the range of electric cars available to dealership networks.
ACEA proposes a slower phase-in
ACEA is now asking the European Commission and EU member states to support a temporary change which would retain a more flexible battery pack assembly rule until the end of 2029.
Stricter localisation requirements for battery cells would then begin in 2030, followed by requirements covering cathode material from 2032.
ACEA said it continues to support the longer-term objective of establishing European battery manufacturing and said vehicle manufacturers have already committed substantial investment to local production.
However, it warned that the resulting capacity will not become available quickly enough to satisfy the January 2027 requirements.
The rules are reciprocal, meaning UK-built electric vehicles exported to the EU face the same sourcing tests. Any change would therefore require the involvement of both Brussels and the UK government.
