UK Tesla Sales Plunge as Electric Vehicle Growth Slows Amid New Road Tax Plans

Tesla’s sales in the United Kingdom suffered a substantial decline last month, emerging as the most prominent casualty of a slowdown in battery electric vehicle growth. The dip coincides with government proposals to introduce a mileagebased road tax for EV drivers, unsettling both manufacturers and consumers.

Industry analysis from the Society of Motor Manufacturers and Traders shows that fewer than 40000 new battery electric vehicles were registered last month, representing a modest 36 percent increase from November 2024. This marks the smallest yearonyear growth since December 2023, when supply chain constraints impacted the market. Despite the rise, BEV market share reached just 264 percent for the year, which lags behind the government’s 28 percent target.

Plans for new road pricing, specifically a paypermile scheme, form part of a broad policy shift designed to address declining revenue from traditional fuel duty. Under the forthcoming rules, electric vehicle excise duty will be set at three pence per mile for fully electric cars and 15 pence per mile for plug in hybrids, effective April 2028. For a battery electric vehicle owner driving the typical 8500 miles per year, the new annual road tax would total £255 in the 202829 tax year.

The announcement triggered immediate concern within the automotive sector. The SMMT issued a sharp warning, arguing that the new duty could endanger the UK’s net zero ambitions and suppress demand at the very point it must accelerate. The Office for Budget Responsibility forecasts that as many as 440000 fewer electric vehicles could be sold over the next five years if these changes proceed.

Tesla experienced a particularly sharp fall in registrations, with sales dropping nearly 20 percent monthonmonth to just 3800 vehicles. The brand’s UK market share now stands at 25 percent. In contrast, Chinese rival BYD saw its registrations, including hybrids and plug in hybrids, more than triple in November.

Growth in battery electric vehicle sales has stagnated within a shrinking overall market; total UK new car registrations fell by 16 percent to 151154 units in November. While diesel and petrol models continued their decline, plug in hybrids recorded the fastest growth, rising by 148 percent and accounting for nearly 12 percent of new registrations.

Additional government measures will extend grants for new electric vehicles until 2030, making select Renault and Mini models eligible for the maximum £3750 discount. Sector analysts note the new mileage charge will add to EV running costs, but modifications to luxury car tax thresholds could potentially offset these rises for some motorists over the lifespan of a lease agreement. Questions remain over the pace of electric vehicle adoption as the 2035 zeroemission transition nears.
