UK zero-emission vehicles reach one in 22 as total fleet hits 42.5 million
By Eve
Britain's vehicle fleet grew 1.4% to 42,549,649 units in 2025, with cars rising by over half a million to 36,676,185, according to SMMT Motorparc data. Zero-emission vehicles now represent one in 22 vehicles on UK roads, marking the fourth consecutive year of fleet growth and the second-largest volume increase since 2016. The expansion reflects a recovering market and accelerating electrification across the national vehicle parc.
Why it matters: The one in 22 zero-emission ratio signals sustained demand for public and workplace charging infrastructure as the electrified fleet expands. CPOs and site hosts can use the 42.5 million fleet baseline and ZEV penetration rate to model utilisation forecasts and justify new installations in 2025.
