Our GP'S are great I never had a problem ever I went to them before I got my visa *spousal) I was here on a 6 month hol, I got a bad chest and ended up in hospital and I had health cover for that, but as soon as I got my spouse visa they put me straight on their books and over the phone they know us, especially me because I was so sick, and then when I went in I filled out a slip (Sonya did) to register with them and that was that no problems at all.
You are entitled to health care free of charge once your on a visa that allows it, such as a spouse visa/fiance ect.
Good luck
Indy and wife
