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 stalling crucial investments and could affect the future of UK car manufacturing and the availability of new electric vehicles.
Why Are Carmakers Waiting?
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 changes to the zero emission vehicle (ZEV) mandate. The mandate forces automakers to sell an increasing share of electric cars each year up to 2030, and the industry is pressing the Labour government to weaken these rules.

Jonathan Reynolds, the business secretary, has indicated that the government is likely to water down the mandate. 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.”
Impact on UK Production
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. This decline highlights the urgency of resolving the policy uncertainty. Companies like Toyota, which has manufactured the Corolla in Derbyshire since 2019, and Mini, which postponed plans to build electric models at its Oxford plant, are among those waiting. Nissan is also in talks to build a car for Chinese manufacturer Chery at its Sunderland plant, but no final decision has been made.
Industry Pressures and Opposition

The British car industry is struggling with competition from China, US tariffs, and the extra costs of investing in electric technology. However, the electric car charging industry strongly opposes any further changes to the mandate, and environmental campaigners warn that weakening the rules could lead to millions of tonnes of extra carbon emissions.
Comparison: Current Mandate vs. Proposed Relaxation
| Aspect | Current ZEV Mandate | Proposed Relaxation |
|---|---|---|
| EV sales target by 2030 | 80% of new cars | Likely lower, unspecified |
| Investment certainty | Low due to strict targets | Higher, encouraging factory upgrades |
| Environmental impact | Lower carbon emissions | Potential increase in emissions |
| Industry competitiveness | Strained by costs | Relief from compliance costs |
Key Takeaways
- Carmakers are postponing UK factory investments until the ZEV mandate is relaxed.
- UK car production fell 7.5% in H1 2026, emphasizing the need for policy clarity.
- Major manufacturers like Toyota, Mini, and Nissan are directly affected.
- Opposition from charging networks and environmental groups adds complexity.
