With the price of fuel going up, employees and businesses will welcome new changes to the fuel advisory rates, which from 1 September 2018 have slightly increased on the previous quarter for some vehicles.
Advisory fuel rates from 1 September 2018
| Engine size | Petrol – amount per mile | LPG – amount per mile |
| 1400cc or less | 12p (11p) | 7p (7p) |
| 1401cc to 2000cc | 15p (14p) | 9p (9p) |
| Over 2000cc | 22p (22p) | 13p (14p) |

Previous rate in brackets. These can be used for up to one month from the date the new rates apply (Hybrid cars are treated as either petrol or diesel cars for this purpose).
Advisory fuels rates apply when:
- reimbursing employees for business travel in their company cars; or
- requiring employees to repay the cost of fuel used for private travel.
HMRC reviews rates quarterly on 1 March, 1 June, 1 September and 1 December.
If you operate your own car, van or motorcycle as part of your business you can calculate your expenses using a flat rate for mileage instead of the actual costs of buying and running your vehicle, such as insurance, repairs, servicing and fuel.
The rates for this are as follows:
| Vehicle | Flat rate per mile with simplified expenses |
| Cars and goods vehicles first 10,000 miles | 45p |
| Cars and goods vehicles after 10,000 miles | 25p |
| Motorcycles | 24p |
