I'm from Guernsey and am currently in the UK for university. I built myself a new desktop PC and want to take it back with me when I travel back to Guernsey in the summer and then transport it back to the UK when I go back to university.
As I built the PC in the UK I was charged VAT on its parts and Guernsey does not have VAT. That means that when a package is sent from Guernsey to the UK customs fees are applied (but not from the UK to Guernsey).
How can I avoid these charges being applied when I re-import the PC to the UK? I would be using a third-party courier.
