Carmakers are delaying final decisions to invest in UK factories until electric car sales rules are relaxed, according to the head of the British car industry’s lobby group. This uncertainty is casting a shadow over the future of automotive manufacturing in the UK, as companies wait for policy clarity before committing billions to new models and production lines.
Why Carmakers Are Pausing Investment
The Society of Motor Manufacturers and Traders (SMMT) chief executive, Mike Hawes, revealed that manufacturers with existing UK operations are considering building new models but have held back so far. The primary reason is the zero emission vehicle (ZEV) mandate, which forces manufacturers to sell an increasing share of electric cars each year up to 2030. This policy, while aimed at reducing carbon emissions, has created significant compliance costs and operational challenges for automakers.

According to Hawes, “They’re waiting for the mandate, certainly. There’s investment decisions on next model, next generation, which need a resolution, need an easing of the mandate.” The industry is under intense pressure from competition with China, US tariffs, and the extra costs of investing in electric technology. As a result, UK vehicle production fell 7.5% in the first half of 2026 compared with a year earlier, with factories producing only 386,000 cars and commercial vehicles, according to SMMT’s latest figures.
Government Signals Potential Relaxation
Jonathan Reynolds, who has returned to the role of business secretary under Andy Burnham, has indicated that the government is likely to water down the mandate. This has given carmakers hope that the rules may be eased, but until a final decision is made, they remain cautious about committing to new investments. The delay is particularly concerning for regions that depend heavily on automotive manufacturing, such as the West Midlands and the North East.
While the electric car charging industry and environmental campaigners strongly oppose any further changes, the SMMT argues that a more flexible approach is necessary to protect jobs and competitiveness. The British car industry is at a crossroads, and the government’s next move will determine whether the UK remains a key player in global automotive manufacturing.

Which Companies Are Affected?
Hawes declined to name specific companies, but industry insiders suggest that Toyota, which has manufactured the Corolla in Derbyshire since 2019, and Mini, which has postponed plans to build electric models at its Oxford plant, are among those waiting. Nissan is also in talks to build a car at its Sunderland plant for the Chinese manufacturer Chery, but no final decision has been made. Jaguar Land Rover is reportedly reviewing its future investment plans as well.
Impact on UK Automotive Industry
The delay in investment is having a ripple effect on the entire supply chain, from parts manufacturers to dealerships. The uncertainty also undermines the UK’s ability to attract new investors, as global automakers look for stable regulatory environments. The SMMT has called for a review of the ZEV mandate to include more flexibility, such as allowing manufacturers to trade credits or extending deadlines.
