Let me just say guys
I don't work or have anything to do with ANY of the Air Ambulance charities so any answer's I give are from good but second had sources.
In answer to Art of flight,
1. I am told they pay full VAT on the fuel bill.
2. It would be the charity that was given the exemption, if they were to use contractors that would have to be taken into consideration.
3. I could not possible comment only to agree with you that it is ridicules that if someone wanted to give them a few thousand liters of fuel the charity would have to pay the VAT on it.
Hope this helps.
