I've only just been told of all the queries questions ect on this site regarding SGK, for gods sake I can't believe how stupid some people are it's so simple and clear. You DO NOT have to sign up at all, you may get a letter "in Turkish" about SGK destroy it as many already have and carry on as before, how simple is that. If you want private insurance get it, it's much cheaper than SGK and better because SGK doesn't cover pre-exsisting health problems and will cancel out UK NHS cover. Anyone questioning this statement I get all my information direct from either British Embassy/consulate and turkish politition friends, I do not rely on heresay, gossip ect. Come on folks it's as simple as ABC.
