Britain’s vehicle fleet has reached its highest level on record, highlighting both steady market recovery and the accelerating transition toward electrification. According to new Motorparc data released by the Society of Motor Manufacturers and Traders (SMMT), total vehicles on UK roads grew by 1.4% in 2025 to 42,549,649 units.
The rise reflects a combination of improved new vehicle supply, stronger demand, and longer vehicle lifespans amid ongoing economic pressures.
Car Numbers Climb for Fourth Consecutive Year
Passenger cars remain the dominant segment, with volumes increasing by more than half a million units year-on-year. The total reached 36,676,185 cars, marking the fourth consecutive annual rise and one of the strongest gains since 2016.
Growth has been supported by a recovering new car market and improved vehicle durability, alongside a thriving aftermarket that is helping keep older cars on the road for longer.
Commercial Vehicles Also Reach New Peaks
Light commercial vehicles (LCVs) and heavy goods vehicles (HGVs) also recorded gains, underlining continued demand across logistics and business sectors. Van numbers rose 1.4% to 5,175,598 units, while trucks edged up 0.2% to 626,566 units.
The bus and coach segment saw modest growth for the first time since 2021, rising 0.2% to 71,300 units. While still significantly below its historical peak, the segment is undergoing notable transformation, particularly through zero-emission adoption.
Electrified Vehicles Gain Ground Across All Segments
Electrification continues to reshape the UK vehicle market. More than one in nine vehicles (10.9%) now feature some form of electrification, while fully zero-emission vehicles account for 4.5% of the total fleet.
Battery electric cars (BEVs) are leading this transition. A record 1,797,809 electric cars are now on UK roads, up 34.7% year-on-year, representing nearly 5% of all cars in use. Growth has been driven by strong manufacturer incentives and supportive government policies.
Commercial segments are also advancing:
– Battery electric vans surged by 34.6%, surpassing 100,000 units for the first time
– Zero-emission buses increased by 65.2%, now accounting for 8.1% of the fleet
– Electric trucks doubled to 1,056 units, though they still represent a very small share of total HGVs
This broad-based growth is helping reduce overall transport emissions, with average car CO2 output falling by 2.9% compared to 2024.
Ageing Fleet Remains a Key Challenge
Despite progress in electrification, the UK’s vehicle fleet is ageing at a concerning pace. A record 45.7% of cars are now more than 10 years old, up from 43.4% the previous year.
The average age of a car has risen to 9.7 years, reflecting ongoing cost-of-living pressures that are prompting drivers to delay replacing their vehicles.
An ageing fleet slows the environmental benefits of electrification, as older internal combustion engine vehicles typically produce higher emissions and lack modern efficiency improvements.
Faster Renewal Needed to Meet Climate Goals
While the growth in electric vehicles is delivering measurable environmental gains, the pace of fleet renewal remains critical. Accelerating the transition to newer, low- and zero-emission vehicles will be essential to further reduce both carbon emissions and air pollutants.
Without stronger turnover in the vehicle parc, the UK risks limiting the full potential of its electrification progress.
