Smarter route to EV transition needed as market reality bites

New analysis reveals assumptions fuelling UK’s EV transition pathway no longer stand against geopolitical and economic reality.
Battery costs 30% more than expected, energy costs 80% higher and natural demand far behind government ambition.
Industry calls for full review of the transition to develop realistic route to decarbonisation while supporting economic growth.

Britain’s transition to zero emission vehicles must urgently be reviewed before targets accelerate exponentially from 2027, the automotive industry has warned, else the country’s net zero and economic growth ambitions could be thwarted.

New analysis published today by the Society of Motor Manufacturers and Traders (SMMT) shows the UK’s transition pathway was built on assumptions that have proved to be over-optimistic.¹ Despite changes to regulatory flexibilities and the return of consumer incentives, the gap between policy ambition and market reality continues to widen.²

The automotive sector remains fully committed to net zero. Conditions have changed so much, however, that failing to reassess the route risks undermining the very objectives the policy was designed to achieve.

Despite having the highest battery electric vehicle (BEV) market share of any major European market, the UK is already falling short of its own expectations. In 2025, battery electric vehicles accounted for 23.4% of new car registrations – below the 28% ZEV mandate requirement, and short even of the 26% government originally expected would be achieved without regulation. This is despite UK drivers enjoying a massive choice of more than 160 BEV models – the result of billions of pounds invested by manufacturers.

The industry has thus far bridged the gap between ambition and demand through unprecedented levels of discounting – more than £10 billion over the past two years – and by using mandate flexibilities. However, such subsidies are unsustainable and undeliverable when at the end of 2027 the targets become significantly tougher (52% for cars, 46% for vans). Natural market demand will not deliver the doubling in new car market share in two years, never mind the quadrupling of electric van market share, needed to achieve these targets.³ Without action to close the gap, fleet renewal and parc decarbonisation will slow, and the UK’s attractiveness as both a vehicle market and manufacturing base will be put at risk.

Global events have undermined the assumptions underpinning the transition. Analysis in Same Destination, Smarter Route, a new report published today at SMMT’s Electrified conference, shows how battery costs are more than 30% higher than anticipated, raw material costs remain stubbornly high, and UK and EU industrial energy prices have risen 80% and 28% respectively since 2021. As a result, the expected price parity between electric and conventionally fuelled vehicles has not materialised, restricting the pace of transition. Charging infrastructure has increased but the cost of public charging has, in some instances, gone up by more than 140% in the past five years,⁴ while a target of at least six ultra-rapid chargepoints at every UK motorway service area by the end of 2023 was only around 70% complete in early 2025.⁵

The challenges are even greater for commercial vehicles. While almost two thirds of new van models are now available as zero emission, uptake in 2025 was 9.6%, barely half of the 16% required by regulation. For heavy goods vehicles, adoption is only just beginning – just 1.4% of the market in 2025 – reflecting the sector’s diverse operating requirements, high upfront costs and the scale of charging and refuelling infrastructure still needed.

Above all, the geopolitical landscape has fundamentally changed with knock-on effects on energy markets, business and consumer confidence, and attitudes to trade which are increasingly protectionist. Only last week, the EU published its draft Industrial Accelerator Act which threatens trade in the very vehicles the EU and UK seek to promote.

Against this backdrop, the industry is calling on government to undertake an urgent strategic review of the transition to zero emission vehicles. This must consider all relevant factors, including the regulation, to assess whether the pathway remains realistic and is aligned with economic growth, recognising that market strength matters to the UK investment proposition.

Other major markets such as the EU and Canada have already altered their transition plans, and the US has rowed back on its EV commitments altogether.⁶ The industry is not calling for abandonment, however, just an urgent review of its own transition and regulatory timescale which remains the world’s toughest.
