Thanks for the correction and link. I was told it had just changed in the recent budget - as you say thankfully not.

If you fly a group aircraft then it's easy - just get the originals from previous refuelling up to the maximum capacity of your tanks. Our group 'accountant' is quite happy with photocopies when you want to claim.
For a club aircraft it's slightly harder. All I can suggest is chat nicely to the club secretary and see if you can get some form of fuel receipt for the full amount - if they can print you one which they can then 'void' in a following transaction for their own accounting purposes that wil do the trick.
