New passenger car registrations in the UK fell by 5% from the previous month in July of 2025, trimming the 6.2% increase from the previous month to mark the first decline in three months. The decline was owed to a sharp decline in registrations of petrol vehicles (-14.7% to 66,271) while significant drops followed for hybrid electric (-10% to 18,551) and diesel vehicles (-7.9% vs 8,018). In turn, sales growth persisted for plug-in hybrid electric (33% to 17,489) and battery electric vehicles (9.1% to 28,825). Sales for electric vehicles were due to pick up in coming months as the government expanded the models that qualify for EV tax grants.
