I used sevenseas to transport some of my belongings over to bkk which went very well, no duties to pay and door to door. Unfortunately they do not have such a service back to the UK, does anyone know a company in Bkk that provides the same sort of service where they pick up and ship back to UK?

I was sent just a small parcel back to the UK and it needed to be cleared through customs which is a pain in the neck. You will need a customs declaration form indicating all of the contents and value etc.

If the goods are personal effects for yourself returning to the uk then there should be no duty etc. but your best bet would be to check with Customs and excise first.
