British new car registrations rose in May. The gain came after months of uneven performance. Fleets led the charge while private buyers held back. And battery electric vehicles posted solid growth even as the industry wrestles with ambitious government targets.
Exactly 150,070 new cars hit UK roads last month, a 1.6% increase from the same period a year earlier, according to the Society of Motor Manufacturers and Traders. That figure marks the strongest May since 2021. Still, it sits 18.3% below pre-pandemic levels from 2019. The rebound follows a sharp 10.4% drop in April when tax changes stung demand.
Year to date, the market stands at 850,903 registrations, up 2.8%. Fleet and business sales drove much of the monthly lift, rising 3.7% and 14.4% respectively. Private registrations slipped 2.3%. This split reveals where confidence lies. Businesses and leasing companies see value. Individual buyers feel the pinch from higher costs and economic jitters.
Electric vehicles provided the clearest bright spot. Battery electric vehicle registrations climbed 25.8% to 32,738 units, claiming 21.8% of the market. Plug-in hybrids surged even faster, up 50.8% to 17,898. Hybrids without plugs added 6.8% growth. Together, electrified powertrains accounted for nearly half of sales.
Yet the numbers tell a more complicated story. Year-to-date BEV share sits at 20.9%, well short of the 28% required under the Zero Emission Vehicle mandate. Manufacturers have responded with aggressive price cuts. Those discounts boosted volumes. They also raise questions about long-term profitability and investment capacity.
Discounting Carries Hidden Costs
Mike Hawes, SMMT chief executive, put it plainly. “A return to growth for new car registrations in May is welcome but manufacturer discounting on new products continues to underpin the market, notably for electric vehicles,” he said in the SMMT release. “This cannot be sustained indefinitely as it undermines the ability of companies to invest in new product development, investments which are integral to the decarbonisation of all road transport.”
The pressure shows. Carmakers poured billions into incentives last year to meet quotas. Some analysts estimate the industry subsidized BEV sales by more than £5 billion in 2025 alone. That approach delivered record EV numbers — 473,348 battery electrics for the full year, pushing the segment to 23.4% of the market. But it fell short of the mandate and strained balance sheets.
Recent data from New Automotive painted an even stronger EV picture for May. The firm reported a 6% overall market rise with BEVs capturing 27% share and surging 31% year-on-year. Rising fuel costs linked to global tensions, including impacts from the Iran situation, have nudged more drivers toward alternatives.

Petrol and diesel sales continued their decline. Petrol registrations fell 12.5% to 71,291 units, still representing 47.5% of the market. Diesel dropped 15.5%. The internal combustion engine segment as a whole lost ground. Its share slipped below 53%. The shift looks permanent. Consumer preferences and policy both point one direction.
Sue Robinson, chief executive at the National Franchised Dealers Association, highlighted the broader strains. She pointed to higher employers’ national insurance, the extension of vehicle excise duty to electric cars, and uncertainty around international tariffs. “We expect electric vehicle sales to continue to increase, however, they still remain someway off the ZEV mandate targets for 2025,” she noted. Dealers have shown resilience before. This period of turbulence tests that record again. (Autovista24)
The mandate itself grows stricter. It demands higher zero-emission shares each year on the road to 2035. Flexibility mechanisms allow some credit for lower-emission combustion vehicles, yet the gap remains. Industry leaders have called for earlier review of the rules, plus fresh incentives. They want VAT cuts on EVs, better home charging support, and reform of vehicle excise duty.
Consumer sentiment adds another layer. Surveys show hesitation. Many buyers cite range anxiety, charging availability, and upfront costs despite discounts. Fewer than one in four new car buyers in early 2025 surveys planned to go fully electric by 2028. Fleet operators move faster. They benefit from tax advantages and lower running costs over time.
Looking further out, the SMMT has upgraded its full-year forecast. It now sees nearly 2.1 million new car registrations in 2026. Battery electric share projections have been trimmed, however, reflecting softer demand earlier in the year. The two millionth electric car milestone passed recently. That moment arrived amid a strong April rebound when BEVs hit 26.2% share. (Reuters, May 5, 2026)
Chinese brands have gained traction with competitive pricing. Tesla saw its May registrations fall from the prior year. Established European and British manufacturers balance volume targets against margins. The discounting cycle cannot last forever. Without policy adjustments, the risk grows that manufacturers miss mandates and face fines. Or they absorb losses that slow innovation.
Infrastructure remains a bottleneck. Public charging points have expanded, yet gaps persist outside major cities and motorways. Home charging installation still carries cost and hassle for many households. Government spending reviews, including one scheduled soon after May data, could shape the next round of subsidies and targets.
The May figures offer relief after April’s slump. Growth returned. Electrification advanced. But the data also expose tensions. Between mandate ambition and market readiness. Between short-term incentives and sustainable business models. Between fleet enthusiasm and private buyer caution.
Automakers, dealers, and policymakers now face choices. Sustain the discounts and risk financial strain. Adjust targets and risk slowing the transition. Or find smarter incentives that stimulate demand without distorting competition. The coming months will test which path delivers both volume and viability.
