have been looking into just this thing today. I am planning on going to the czech rep, and the surgeon has stated that he will cover any probs for 7 days whilst their but anyother problems will not be covered. I rang wls today to see what they could offer me and how much it would cost. They will not cover anything medical i.e. sorting out complications, but they did say that the nhs has got to do this. They will provide an aftercare service for diet probs check ups with a bariatric nurse any diet probs etc etc and its about 500 pounds for a two year period. if you require any medical help they said companies tend to want you to use an approved surgeon pref one of their own, If you do manage to find out anything else keep me posted.
