The rates
Flat rate per mile, per monthly assessment period
- Car, van or other motor vehicle, first 833 miles
- 45p a mile
- Car, van or other motor vehicle, every mile over 833
- 25p a mile
- Motorbikes or scooters
- 24p a mile
The 833 mile threshold resets with each assessment period, so it is a monthly threshold rather than a yearly one.
Mileage instead of running costs, not as well
The flat rate is meant to cover what the vehicle costs you to run. If you claim mileage for a vehicle, you are not also claiming its fuel, servicing, insurance and repairs on top. Claiming both is claiming the same spending twice, and it is the kind of thing a check finds.
Buying, leasing or hiring the vehicle
You cannot claim expenses to buy, lease or acquire a car or minicab if the vehicle is not specially adapted for business use.
An ordinary car or minicab is on the flat rate, full stop. A vehicle that is specially adapted for business use is treated differently, and gov.uk is the place to check your particular case.
Which miles count
Business miles. gov.uk is clear that commuting, meaning travel between your home and your normal place of business, is not claimable, and neither is personal travel. For a private hire or delivery driver with no fixed place of business, the picture is different from an office worker, so the honest answer is that it depends on your own working pattern and your work coach is the person to confirm it with.
