HMRC has released its latest advisory fuel rates (AFRs) which will come into force from March 1.
The new reimbursement rate for a diesel car with an engine size of more than 2,000cc decreases by 1p per mile (ppm), from 14ppm to 13ppm.
However, the rate for a diesel company car with an engine of 1,601cc to 2,000cc stays the same, as does the rate for a diesel car with an engine of 1,600cc or less.
There is also a 1ppm reduction for the reimbursement rate for a petrol company car with an engine size of more than 2,000cc. It is reduced from 21ppm to 20ppm, while the remaining petrol rates remain unchanged.
Meanwhile, the AFR for LPG vehicles with an engine of 1,400cc or less will stay the same at 8ppm, as will the rate (14ppm) for LPG company cars with an engine size of more than 2,000cc.
However, for LPG vehicles with an engine from 1,401-2,000cc, the rate increases from 9ppm to 10ppm.
Hybrid cars are treated as either petrol or diesel cars for AFR purposes.
The advisory electricity rate (AER) for plug-in cars remains unchanged at 4ppm.
