I understand that non-residents (so presumably British expats) can claim back the VAT they have paid on things bought in the UK. How easy is it to do that?
How do you prove you aren't resident in the UK if you have a British passport? Has anyone done this? Is it much hassle? And do you make the claim at the airport? What's the process - refund onto a credit card, cash...? How long does it take?
Thanks.
