From 1 March 2026, the recently introduced split advisory electric rates has risen 1p for public charging, and remains unchanged for domestic use.

For journeys where a company car is charged at both public and residential locations, companies can apportion the mileage based on how much charging happens at each place. The apportionment calculation should be ‘fair and reasonable’, HMRC said.

The advisory fuel rates for petrol and diesel remain unchanged on previous quarter. These rates last changed nine months ago highlighting stability of fuel prices although this will likely be impacted by rise in barrel costs due to war in the Middle East.
