Carmakers Delay UK Factory Investments Until EV Rules Relaxed 2026

Carmakers are delaying UK factory investments until electric vehicle (EV) sales rules are relaxed, according to the head of the British car industry's lobby group. The Society of Motor Manufacturers and Traders (SMMT) chief executive Mike Hawes confirmed that manufacturers with existing UK operations are holding back on new model decisions pending government policy changes.

Why Carmakers Are Waiting on EV Mandate Changes

The zero emission vehicle (ZEV) mandate requires manufacturers to sell an increasing share of electric cars each year up to 2030. Industry leaders argue the current targets are too aggressive, especially amid competition from China, US tariffs, and rising technology costs.

Hawes stated, "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." This hesitation is stalling crucial investments in UK factories, impacting jobs and long-term competitiveness.

Impact on UK Vehicle Production

UK vehicle production fell 7.5% in the first half of 2026 compared with the same period last year, with factories producing just 386,000 cars and commercial vehicles, according to SMMT's latest figures. This decline highlights the urgency of resolving the policy uncertainty.

Which Manufacturers Are Affected?

Hawes declined to name specific companies, but reports suggest Toyota, which builds the Corolla in Derbyshire, and Mini, which postponed electric model production at its Oxford plant, are among those waiting. Nissan is also in talks to build a car for Chinese manufacturer Chery at Sunderland, but no final decision has been made.

Government Response and Industry Pressure

Business secretary Jonathan Reynolds has indicated the government is likely to water down the mandate. However, the electric car charging industry and environmental campaigners oppose any weakening, citing the risk of millions of tonnes of extra carbon emissions.

• Key takeaway: Carmakers are postponing investment decisions until EV rules are relaxed.
• Key takeaway: UK vehicle production dropped 7.5% in H1 2026, underscoring the urgency.
• Key takeaway: Major manufacturers like Toyota, Mini, and Nissan are affected.
• Key takeaway: Government is under pressure to ease the ZEV mandate.

What This Means for the UK Auto Industry

The delay in factory investments threatens the UK's position as a leading automotive manufacturing hub. Without policy clarity, companies may shift production to other countries with more favorable regulations, leading to job losses and reduced economic output.

Industry experts argue that a balanced approach—one that supports EV adoption while giving manufacturers flexibility—is essential. The SMMT continues to call for a review of the mandate's timelines and penalties.
