2023/24

• Advisory rates only apply where employers reimburse employees for business travel in a company car or require employees to repay the cost of fuel used for private travel in a company car.
• If the rate paid per mile of business travel is no higher than the advisory rate for the particular engine size and fuel type of the car, HMRC will accept that there is no taxable profit and no Class 1 NIC liability.

The advisory fuel rates for journeys undertaken on or after 1 March 2023 are:

Engine size	Petrol
1400cc or less	13p
1401cc - 2000cc	15p
Over 2000cc	23p

Engine size	Diesel
1600cc or less	13p
1601cc - 2000cc	15p
Over 2000cc	20p

Engine size	LPG
1400cc or less	10p
1401cc - 2000cc	11p
Over 2000cc	17p

Hybrid cars are treated as either petrol or diesel cars for this purpose.

The Advisory Electricity Rate for fully electric cars is increased from 8p to 9p per mile. Electricity is not a fuel for car fuel benefit purposes.
