Battery electric vehicles (BEVs) accounted for more than a quarter of all new cars registered in the UK during May, marking one of the strongest months on record for electric vehicle adoption and reinforcing evidence that consumer demand for EVs continues to accelerate.
According to the latest Electric Car Count from New AutoMotive, BEVs captured 27.1% of the UK new car market in May 2026, while registrations rose 31.2% year-on-year to 41,346 vehicles. The growth made pure electric cars the fastest-growing major segment of the market during the month, comfortably outpacing the overall new car market, which expanded by 5.7%.
The figures arrive as the UK continues its transition towards zero-emission transport under the ZEV Mandate and suggest electric vehicles are becoming increasingly mainstream rather than remaining a niche choice for early adopters.
Combined registrations of battery electric and plug-in hybrid vehicles accounted for more than 40% of all new cars sold during May. In contrast, petrol registrations fell by 13.6% and diesel registrations declined by 5.8%, continuing a trend that has seen conventional combustion-powered vehicles steadily lose market share.
New AutoMotive said May represented one of the strongest months for electric vehicle adoption outside the traditional December registration peak, demonstrating sustained momentum across the market.
Ben Nelmes, Chief Executive of New AutoMotive, said:
“The missing piece of the puzzle for the UK's EV transition is finally in place.
“Carmakers have invested billions to bring a wide range of accessible electric models to market. Now we see decisive evidence that consumer demand is surging as motorists, spurred on by global events and rising fuel prices, are opting for electric cars.
“Electric cars offer Britain a critical opportunity to improve energy security, strengthen our economy and build resilience in an increasingly unstable world.”
The organisation's latest analysis links part of the recent surge in EV demand to volatility in global oil markets. New AutoMotive noted that drivers increasingly view electric vehicles as protection from fluctuating fuel prices, particularly as geopolitical tensions continue to affect oil supplies and energy markets.
The May figures also reveal a significant shift in where EV growth is coming from. Rather than being driven primarily by premium manufacturers, mainstream brands are increasingly taking centre stage.
Volkswagen and Kia led the monthly BEV rankings, benefiting from strong demand for their latest generation of electric models. New AutoMotive argues this demonstrates that the EV market is broadening beyond luxury segments as manufacturers introduce more affordable and practical electric vehicles.
Competition across the sector remains intense. The top ten manufacturers accounted for just 58% of battery electric registrations during the month, leaving more than 40% distributed across a diverse range of brands.
Year-to-date data paints a similarly positive picture for electrification. Battery electric vehicles now account for 23.7% of all UK car registrations in 2026 so far, with registrations up 18.5% compared with the same period in 2025.
Plug-in hybrids continue to grow strongly as well, increasing 32.5% year-to-date and capturing 12.8% market share. However, questions remain over the real-world emissions performance of some PHEVs compared with fully electric vehicles.
The latest figures also provide a snapshot of the UK's progress towards meeting ZEV Mandate targets. While the headline 2026 target requires 33% of car sales to be zero-emission, New AutoMotive estimates that flexibilities built into the scheme reduce the effective market-wide target to approximately 24.6%.
With BEVs accounting for 23.7% of registrations so far this year, the market is now within touching distance of that adjusted target.
Several manufacturers have already built substantial surpluses of ZEV credits, including Tesla, BYD, SAIC, Geely, Chery and Renault. Others, including Volkswagen Group, Stellantis, Hyundai, BMW, Ford, Mercedes-Benz, Toyota and Nissan, currently remain in deficit, although New AutoMotive notes there is still considerable time for manufacturers to improve their positions before the end of the compliance year.
Industry leaders have welcomed the latest registration figures as evidence that consumer demand for electric vehicles is stronger than critics often claim.
Tanya Sinclair, Chief Executive of Electric Vehicles UK, said:
“Why are we told that the public isn't ready, and the demand isn't there? 27% says otherwise. This is the mainstream choosing electric on its own terms, because it's cheaper to run and better to own.
“Instead of scare-mothering about readiness, let's all ensure supply, charging and policy keep pace with a market that's going electric at pace.”
Ginny Buckley, founder and Chief Executive of Electrifying.com, added:
“The latest figures should finally put to bed the old chestnut that drivers don't want electric cars.
“Car buyers aren't choosing EVs to make a statement, it's because they're cheaper to run, enjoyable to drive and less exposed to the volatile global oil prices that can send fuel costs soaring overnight.
“It's time to stop talking about electric cars as an ‘alternative', because these numbers put EVs firmly in the mainstream of the UK car market.”
Gurjeet Grewal, Chief Executive of Octopus Electric Vehicles, said the latest figures demonstrate that the UK's EV transition is becoming self-sustaining.
“Month after month, the UK is proving that the ZEV mandate isn't a stretch target – it's a reality. Driven by growing consumer demand, the conversation has moved from ‘can we get there?' to ‘how much further can we go?'”
The commercial vehicle sector is also showing increasing signs of electrification. Electric van registrations rose 33.2% year-on-year during May, reaching 2,213 vehicles and giving battery electric vans a 10.3% market share for the month.
According to New AutoMotive, this represents the highest number of BEV van registrations and the largest BEV market share ever recorded for the month of May.
Year-to-date, battery electric vans account for 9.7% of registrations, while plug-in hybrid vans have more than doubled compared with the same period last year. Volkswagen currently leads the electric van market, followed by Ford and Kia.
The report highlights that fleet operators are increasingly embracing electrification, although challenges remain around charging infrastructure and grid connections. New AutoMotive argues that government support for commercial charging infrastructure could help accelerate adoption further, particularly for businesses operating larger van fleets.
Beyond passenger cars and vans, progress remains slower in other transport sectors. Electric heavy goods vehicle registrations reached 34 units in May, representing just 1.2% of the market, while electric motorbike registrations fell 36% year-on-year.
Nevertheless, the headline story from May remains clear. Electric vehicles continue to gain market share at the expense of petrol and diesel models, consumer demand appears stronger than ever, and the UK's transition towards zero-emission transport is increasingly being driven by mainstream buyers rather than early adopters.
With more affordable EVs entering the market, charging infrastructure continuing to expand and operating costs remaining attractive compared with conventional vehicles, May's figures suggest that Britain's electric vehicle revolution is moving firmly into its next phase.
