Iwork for the NHS, and it depends upon engine size and number of miles driven for work purposes. I've got an 1800, and used to get 53p per mile. As I now do over 100 miles a month, I qualify for 'Regular User' allowance and get a lump sum of �63, and 40p per mile. Which looking at the other two answers is pretty good. But then again, my NHS salary is crap.
