There are two separate policies that govern travel expenses; one for paid staff and another for trips undertaken as part of a sport or society activity.
The two expenses systems are;
Staff Less than 80 miles
45p per mile
Staff over 80 miles
£29 plus the mileage at 10.5p per mile or the mileage at the casual user rates, whichever is the lowest amount.
Sport/Society Activity - Students
Flat rate of 25p per mile
60 miles : Staff = £27, Student = £15
120 miles : Staff = £35, Student = £30
180 miles : Staff = £44, Student = £45
Remember that almost all fuel reclaims are for under 120 miles - so staff almost always get paid more (& often don't have cars loaded up with equipment)
Figure correct as of April 2016
(HMRC recommended rate is 45p per mile regardless of distance)
