Proposed European Union manufacturing rules could place UK-built vehicles at a competitive disadvantage in their largest overseas market, according to new analysis of the economic links between the British and European automotive industries.
The Society of Motor Manufacturers and Traders is pressing for the UK to be treated as an equivalent partner under planned “Made in Europe” provisions being discussed as part of the EU’s Industrial Accelerator Act. The trade body argues that excluding British production from incentives and procurement provisions would cut across highly integrated automotive supply chains.
Research commissioned by the SMMT from Oxford Economics estimates that UK automotive production supports €24bn of economic activity across EU member states and 250,000 jobs through supply chain activity and spending by employees. The figures use 2024 economic relationships and measure activity connected to British production rather than forecast losses from a future policy change.
The wider cross-Channel automotive trading relationship is worth about €80bn annually. The UK is the EU’s largest export market for passenger cars, while EU suppliers sell more automotive components to Britain than to any other international market.
UK automotive exports to the EU are estimated to generate €5.6bn of spending on goods and services in the bloc, supporting 58,000 jobs and €1.6bn of tax revenues. Those measures describe different economic effects and are not additive. The research also identifies substantial activity linked to British production in Germany, France, Italy, Spain, Poland, Romania, Czechia, and Slovakia.
The policy concern centres on how European origin is defined. Under the provisions described by the SMMT, UK-built vehicles could be excluded from incentives offered to products meeting a “Made in Europe” threshold, including measures linked to greener corporate fleets and certain carbon-related credits. They could also fall outside some member-state procurement schemes.
Such treatment would create a new non-tariff distinction within a manufacturing system in which components frequently cross borders before a finished vehicle reaches a customer. Vehicle manufacturers have spent decades developing regional sourcing networks around specialised engines, electronics, braking systems, interiors, batteries, and other components rather than reproducing every part of the manufacturing chain in each country.
Mike Hawes, chief executive of the SMMT, said: “Despite Brexit, supply chains remain deeply integrated and the cross-Channel trading relationship is worth €80 billion a year.”
European policymakers are simultaneously trying to increase domestic industrial capacity, accelerate lower-emission vehicle production, and respond to competition from manufacturers in the US and Asia. Local-content requirements can direct procurement and investment towards domestic production, but their commercial effect depends heavily on the geographic boundary used to determine eligibility.
The question for British manufacturers extends beyond tariffs. Preferential treatment for EU-built products in fleet incentives, government purchasing, or regulatory credits could influence future model allocation and investment even where ordinary cross-border trade remains tariff-free.
The issue also intersects with rules of origin, another important part of the UK-EU automotive relationship. Electric vehicles and their batteries create particular challenges because the origin of high-value components determines whether products qualify for preferential trading terms.
Industry groups have previously argued that policy must reflect the gradual development of European battery and component capacity rather than assume regional supply chains can be rebuilt immediately. Investment decisions on battery plants, vehicle platforms, and specialist component production often run over several years, making future eligibility rules relevant well before they take effect.
Manufacturers also have to consider the cumulative effect of regulatory and industrial-policy measures. A vehicle can remain technically eligible for tariff-free trade while becoming less attractive in a market if tax incentives, fleet rules, procurement policy, or environmental credits favour locally defined production.
The SMMT analysis does not model how manufacturers or consumers would respond if the provisions were adopted, and its €24bn estimate should not be read as a forecast of losses. It instead sets out the scale of EU economic activity currently connected with British automotive manufacturing.
The eventual treatment of UK production will determine whether the next phase of European industrial policy continues to accommodate the existing cross-Channel manufacturing network or places greater weight on production located formally inside the EU.
