The latest news from the HMRC is that they have published updated advisory fuel rates, which show reductions in the majority of categories.
See a full list of figures in the tables below; the summary being that there is a reduction of 1p per mile for diesel drivers, and up to 2p for petrol
These rates apply to all journeys on or after 1 December 2013 until further notice.
For one month from the date of change, employers may use either the previous or new current rates, as they choose. Employers may, therefore, make or require supplementary payments if they so wish, but are under no obligation to do either.
| Engine size | Petrol | LPG |
| 1400cc or less | 14p | 9p |

| Engine size | Diesel |
| 1600cc or less | 12p |
| 1601cc to 2000cc | 14p |
| Over 2000cc | 17p |
Hybrid cars are treated as either petrol or diesel cars for this purpose.
