Battery-electric cars took 32.0% of Britain's new-car market in October, their highest share of 2026, according to figures the Society of Motor Manufacturers and Traders (SMMT) published on 5 November. BEV registrations rose 32.7% to 48,858, in a market that grew 5.4% to 152,730 cars, its 11th consecutive month of growth.
Tesla registered 282 of them. That is 0.2% of the market and 44.8% fewer than the 511 Teslas registered in October 2025. It puts Tesla 41st of the 54 brands that registered cars in October, according to SMMT's brand table, behind Xpeng (330), GAC's Aion (385) and Polestar (864). BYD registered 6,065 cars, up 73.3%, although its total includes plug-in hybrids.

Why one month says little about Tesla
Tesla's British registrations follow its delivery quarter, and October, the first month, is the quiet one: a year ago it produced only 511. A month earlier, as our September report showed, the Model 3 and the Model Y took the top two places among electric cars, with 9,929 and 5,946 registrations, or 15,875 between them.
The year-to-date figures are the better guide. Tesla has registered 46,526 cars in Britain since January, up 31.2% on the same period of 2025. That makes it 20th among all brands, with 2.5% of the market. Every Tesla is battery-electric, so that is 9.2% of the 503,805 BEVs registered this year. New AutoMotive's DVLA-based estimate, published a day before SMMT's figures, still had Tesla as the year's biggest electric brand with 9.5% of BEVs, ahead of Kia (6.9%) and BYD (6.8%), Drive Tesla reported. The same estimate made Kia October's biggest electric brand, with about 3,600 registrations.
October's ten best-selling electric cars were led by the Škoda Enyaq on 1,568, followed by the Mini Countryman and the Jaecoo 5. The BYD Seal was sixth on 1,207 and the Leapmotor B10 tenth on 1,028. No Tesla made the list.
The mandate gap the industry wants closed
The ZEV mandate requires 33% of each manufacturer's 2026 car sales to be zero-emission. The year-to-date share is 26.6%. SMMT's latest outlook expects 27.2% for the full year, then 32% against a 38% target in 2027 and 37.5% against 52% in 2028, a gap it says will more than double. It says carmakers are spending billions on discounts, 0% finance, deposit contributions and subsidised charging, and it wants the targets revised down this year. It also criticised the pay-per-mile EV tax from 2028 and the plan to keep 20% VAT on public charging while home charging is VAT-free.
The headline target is not the one manufacturers must actually meet. The scheme's flexibilities lower it, and New AutoMotive estimates the effective 2026 target at 24.6%, which Britain's 26.6% already clears.
What it means for Tesla buyers
The government's list of cars eligible for the Electric Car Grant, which SMMT counts among the incentives behind this year's demand, names no Tesla, and rivals that qualify can undercut it, as the new Hyundai Ioniq 6 now does the Model 3. After a month this quiet, November and December will show whether Tesla's 31.2% year-to-date growth holds.
