Tesla’s UK car registrations fell sharply in November, declining 19% year-on-year, according to preliminary data released on Thursday by research group New AutoMotive.

Registrations of Tesla vehicles — a closely watched proxy for sales — dropped to 3,784 units last month, down from 4,680 cars sold during the same period a year earlier.

The decline in Britain mirrors steep falls across several major European markets for the U.S. electric vehicle maker. Tesla has been grappling with an aging product lineup and intensifying competition in an increasingly crowded European EV landscape, particularly from fast-growing Chinese manufacturers.

Although the company has recently begun rolling out updated versions of its best-selling Model Y SUV, pressure is mounting as consumer choice expands. More than 150 electric vehicle models are now available to British buyers, according to EV buying advice site Electrifying.com.

Among Tesla’s rivals, Chinese automaker BYD posted especially strong growth. Registrations of BYD vehicles — which include hybrids and plug-in hybrids — surged 229% in November to 3,217 cars.

Tesla has also faced headwinds from shifting public sentiment. Customer perception of the brand has weakened in recent months following chief executive Elon Musk’s public praise of right-wing political figures and his brief tenure as head of the U.S. Department of Government Efficiency.

The slump in UK sales aligns with Tesla’s wider European performance. The company recorded a 20% drop in Germany and an almost 60% collapse in France and other European markets, declines that were only partly offset by record sales in Norway.

Across the broader market, total new car registrations in Britain fell 6.3% in November to 146,780 vehicles, New AutoMotive said. Battery-electric vehicle registrations edged down 1.1% to 38,742 units, while plug-in hybrid sales rose 3.8% to 16,526. Photo by U.S. Department of Energy from United States, Wikimedia commons.
