The uptake of battery electric vehicles rose just 0.1% to 29,654 units in January 2026 – delivering a 20.6% market share, the lowest since April 2025, the latest SMMT figures show.

The SMMT says that the decrease follows a strong 2025 January performance when uptake was pulled forward as buyers sought to avoid April’s introduction of new tax rates on BEVs. Furthermore, the strong BEV performance at the end of 2025, with manufacturers pushing to meet regulatory targets, will also have affected the January market.

The largest growth was recorded in plug-in hybrids (PHEVs), rising 47.3% to account for 12.9% of registrations. Hybrid electric vehicles posted a 4.8% increase, comprising 13.4% of the market.

With January typically a lower volume month and not necessarily indicative of the full year trend, the latest market outlook forecasts new car registrations to grow 1.4% over 2026 to reach 2.048 million units – a more optimistic outlook than that previously published in October.

Overall, the UK new car market grew by 3.4% in January to reach 144,127 units, resulting in the best start to a year since pre-pandemic 2020.

Growth was recorded across all buyer types, with registrations by private retail buyers up 4.5% and fleets increasing by 1.6%, while the low-volume business segment rose 46.5%. Fleets remained by far the largest source of new car registrations, accounting for 61.2% of the market.

Mike Hawes, SMMT Chief Executive, said: "Britain’s new car market is building back momentum after a challenging start to the decade. It is also decarbonising more rapidly than ever and, despite a January dip in EV market share, the signs point to growth by the end of the year. The pace of the transition, however, may be slowing and is certainly behind mandated targets. With sales of new pure petrol and diesel cars planned to end in less than four years, there needs to be a comprehensive review of the transition now, to ensure ambition can match reality."
