⚡ New SMMT data — the full picture
Not sure what 29.8% means for you? Our July EV market report explains the trends behind the numbers, and the car comparison tool lets you shortlist the models Britain is actually buying.
London, 7 September 2026 — Battery-electric cars claimed nearly three in every ten new registrations in the UK last month, according to figures published by the Society of Motor Manufacturers and Traders (SMMT). BEVs took a 29.8% share of the August market — up from 26.5% a year earlier — as the UK posted its ninth consecutive month of new-car market growth.
August was a record month for EVs — with a seasonal caveat
August is traditionally one of the quietest months of the UK car market, with many buyers holding off for the September number-plate change. Even so, new car registrations rose 13.7% year-on-year to 94,236 units — the strongest August since the twice-yearly plate system was introduced, the SMMT reports.
Within that total, 28,063 battery-electric vehicles were registered, up 27.7% on August 2025. The 29.8% share was the second-highest monthly figure of 2026 so far — but the SMMT is careful to point out that August's low volumes amplify percentage swings, and that a recurring seasonal spike has appeared every August since 2023. In other words: watch September, not August, for the real demand signal.
Plug-in hybrids grew even faster, up 39.8% to a 14.5% share, while full hybrids rose 26.3% to 12.7%. Petrol was the only fuel type to fall, down 3.5% — a 38.3% share.
Tesla Model 3 returns to the top of the EV chart
The Tesla Model 3 was the UK's best-selling electric car in August with 1,296 registrations, knocking the Renault 5 off the top spot it took in July. Tesla's Model Y followed with 884, ahead of the Vauxhall Frontera (875) and the rapidly rising Jaecoo E5 (855). The Carwow analysis of the SMMT data lists the full top ten:
- Tesla Model 3 — 1,296
- Tesla Model Y — 884
- Vauxhall Frontera — 875
- Jaecoo E5 — 855
- Mercedes-Benz CLA — 821
- Skoda Enyaq — 807
- Skoda Elroq — 805
- Renault 5 — 736
- Kia EV3 — 735
- Audi Q6 e-tron — 603
Across the whole market, the Ford Puma remained Britain's best-selling car (2,795), with Chinese brands continuing their surge — the Jaecoo 7 took second place overall (2,022) and the Jaecoo 5 fourth (1,670), a sign of how quickly new entrants are reshaping the new-car market.
Year-to-date: a record 25.6% — still short of the mandate target
Over the first eight months of 2026, 355,746 BEVs were registered, giving electric cars a record 25.6% year-to-date market share, up from 21.9% at the same point last year. By the end of August more than 2.18 million fully electric cars were on UK roads — around 6.3% of the car parc, according to Zapmap's tracker of SMMT data.
That still leaves the industry well below the 33% zero-emission-vehicle mandate target for 2026, and the gap is shaping policy. The government has launched a review of the mandate — which currently requires 33% of new car sales to be zero-emission this year, rising to 80% by 2030 — and the industry has broadly welcomed the move. Mike Hawes, SMMT chief executive, called August "a bright spot" but warned that "September will be the acid test."
Why September's 76 plate matters more than August
September brings the new 76 registration plate and the industry's biggest sales month of the second half of the year. With more than 170 zero-emission models now on sale and manufacturers discounting heavily — helped by the revived Electric Car Grant worth up to £3,750 on eligible models under £37,000 — the September plate change is where the market's real direction will show. Drivers weighing up a switch should also factor in the VED calculator and charging cost calculator to model the true running costs before ordering.
The bigger picture
August's numbers confirm three trends that matter for anyone following the UK EV market:
- Electrified is mainstream — BEVs, PHEVs and HEVs combined took 57% of the August market; petrol alone fell below 40%.
- Chinese brands are a structural force — Jaecoo, Omoda and MG now occupy several top-ten slots across both the overall and EV charts.
- The mandate review is the story to watch — how the government recalibrates 2030 targets will shape pricing, incentives and supply for the rest of the decade.
For buyers, the practical takeaway is simple: choice has never been wider and deals are being driven by regulatory pressure as much as demand.
