Advisory fuel rates for company cars are updated on a quarterly basis due to fluctuations in fuel prices. The rates determine the amount that can be paid to an employee using a company car for business mileage, without income tax consequences. HMRC has now published the advisory rates applicable from 1 March 2024. The rates for diesel and petrol engines have decreased, whilst LPG rates have increased.

The rates per mile will be:

Engine size	Petrol	LPG
1,400cc or less	13p	11p
1,401cc to 2,000cc	15p	13p
Over 2,000cc	24p	21p

 

 

 

 

 

Engine size	Diesel
1,600cc or less	12p
1,601cc to 2,000cc	14p
Over 2,000cc	19p

 

 

 

 

 

The rate for fully electric vehicles remains unchanged from the previous quarter at 9p per mile. Hybrid cars are treated as either petrol or diesel cars for the purposes of advisory fuel rates.

These rates apply from 1 March 2024, but you can still use the previous rates for one month from that date. Those with diesel or petrol engines and high mileage for February would be slightly better off by using the rates for the current quarter (13p, 15p and 20p per mile for diesel and 14p, 16p and 26p per mile for petrol).
