I drive a company van in the course of my work. Last month I had a nice letter from the inland revenue telling me my tax code will drop, my tax allowance being cut by 3000 quid!
The van is only used for work, I have my own car to run around in at all other times....so now I'm being taxed even more for doing my job. Nice.
The company pays for the AA membership, as someone said, it's their vehicle, so they should take care of it.
I suppose, angel pie, if you break down on non business travel, maybe it's not too heavy a price to bear. good luck.
