The UK automotive industry is facing a critical structural challenge. The Society of Motor Manufacturers and Traders (SMMT), the country’s primary automotive trade body, has issued an urgent call to action for the UK Government. SMMT is demanding an immediate policy review of the Zero Emission Vehicle (ZEV) Mandate, arguing that current legislative targets are severely disconnected from actual market demand. Without rapid intervention, the trade body warns of mounting manufacturing costs, rising global protectionism, and a heightened risk of industry disinvestment.
The ZEV Mandate Mismatch: Target vs. Market Reality
The ZEV Mandate, first outlined in 2020 and implemented in 2024, originally required car manufacturers to ensure that 22% of their new car sales were fully electric. This target escalated to 28% in 2025 and is scheduled to reach 33% in 2026, on an aggressive trajectory toward 80% by 2030. However, the consumer market is not keeping pace. SMMT data shows that battery electric vehicles (BEVs) achieved a 23.4% market share in 2025, and currently hover at 23.9% for cars and just 9.5% for vans.
To force compliance and avoid heavy regulatory fines, manufacturers have collectively spent over £12 billion in retail discounts to artificially stimulate demand. SMMT Chief Executive Mike Hawes highlighted that this capital drain directly undermines the industry’s capacity to invest in new models, support job creation, and sustain UK operations. The financial pressure is set to intensify in January 2027, when the mandate targets spike to 38% BEV sales for passenger cars and 34% for commercial vans.
UK-EU Rules of Origin and Tariff Threats
Beyond domestic compliance, the UK auto sector is facing a severe cross-border trade threat. Under the EU-UK Trade and Cooperation Agreement (TCA), tougher rules of origin scheduled for January 2027 will introduce a 10% tariff on roughly 70% of all electric and plug-in hybrid models traded across the English Channel. The SMMT projects that this tariff barrier will impose a £1.4 billion tax bill in 2027 alone, putting £16.4 billion of bilateral EV trade at risk. Additionally, the European Commission’s proposed ‘Made in Europe’ regulations could exclude UK-assembled automotive components unless the EU recognizes UK manufacturing as part of its internal supply chain. SMMT surveys show that 83.3% of UK automotive business leaders believe their local operations will suffer if these rules are enacted without modification.
High Operating Costs and the Blueprint for Reform
Domestically, auto manufacturers are struggling with high input costs. SMMT surveys show that 93.5% of businesses report worsening employment costs and 84.8% face higher material input costs over the past year. While industrial energy cost support, such as the British Industrial Competitiveness Scheme (BICS), has offered some relief, UK industrial electricity rates remain among the highest in Europe, sitting approximately 60% above the EU average. Consequently, 70% of automotive executives cite lowering energy costs as their top priority for improving business competitiveness.
To navigate these challenges, the SMMT has delivered a comprehensive blueprint to the incoming Prime Minister. The organization is calling for a balanced regulatory framework that protects the industry’s £4 billion DRIVE35 investment fund, supports transition pathways, and safeguards international trade relations. Reforming the ZEV Mandate is not about lowering environmental targets, but about establishing a practical, market-led pathway to zero emissions that allows the UK automotive sector to manufacture, export, and remain globally competitive.
