Press release
26 November 2025
Commenting on changes to electric vehicles and car fleets announced in the Budget, Simon Down, automotive tax director at Deloitte, said:
“The EV mileage charge, due to come into effect in April 2028, will mean an increase in the running costs of electric vehicles, albeit not a significant impact on consumer finances. Based on an average annual mileage of 7,100, the charge would cost Battery Electric Vehicle (BEV) drivers c.£213, and Plug-In Hybrid Electric Vehicle (PHEV) drivers c.£107 per year respectively. An increase of c.£213 per year would equate to a c.2% increase in the overall cost of funding a typical fleet car.
“The proposed changes to the threshold for the Expensive Car Supplement (ECS) for vehicle excise duty in 2025 will see the threshold rise to £50,000 from £40,000. This can save drivers £440 per year and applies from years two to five of ownership. Over a typical four-year lease, this will save consumers £1,320.
“When combined, if a consumer’s EV is valued below £40,000, or over £50,000, they will see a small cost increase from April 2028. However, if the EV costs between £40,000 and £50,000, this Budget means the consumer may be c.£900 better off over the four-year lease, saving £1,320 in ECS but paying an extra £426 in EV mileage charges.”
