Carmakers Delay UK Factory Investment Until EV Rules Relaxed 2026

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. The uncertainty around the zero emission vehicle (ZEV) mandate is stalling billions in potential investment, threatening jobs and the UK's manufacturing competitiveness.

Why Carmakers Are Holding Back on UK Factory Investment

The Society of Motor Manufacturers and Traders (SMMT) chief executive Mike Hawes confirmed that manufacturers with existing UK operations are considering building new models but have held back pending government policy changes. The ZEV mandate currently forces automakers to sell an increasing share of electric vehicles each year up to 2030, but the industry argues the targets are unrealistic given current consumer demand and infrastructure gaps.

Jonathan Reynolds, the business secretary, has indicated the government is likely to water down the mandate. This has created a wait-and-see atmosphere among global carmakers, who are reluctant to commit capital without clearer regulatory certainty.

Impact on Production and Jobs

UK vehicle production fell 7.5% in the first half of 2026 compared with the same period last year, with factories producing only 386,000 cars and commercial vehicles, according to SMMT data. This decline is directly linked to the investment freeze, as factories cannot plan new model lines or retool assembly plants without knowing the regulatory environment.

Potential investors include Toyota, which has manufactured the Corolla in Derbyshire since 2019, and Mini, which has postponed plans to build electric models at its Oxford plant. Nissan is also in talks to build a car at Sunderland for Chinese manufacturer Chery, but no final decision has been made. Jaguar Land Rover is similarly monitoring the situation.

Industry and Environmental Reactions

The electric car charging industry has strongly opposed any further changes, fearing that weaker mandates will reduce EV adoption and undermine charging infrastructure investments. Environmental campaigners are also aghast, warning that relaxing the rules could result in millions of tonnes of extra carbon emissions.

However, Hawes argues that the current targets are unworkable without stronger consumer incentives and grid upgrades. “They’re waiting for the mandate, certainly,” he said. “There’s investment decisions on next model, next generation, which need a resolution, need an easing of the mandate.”
