I've read a couple of people mentioning lately about people going to the UK to live permenantly and not being able to get NHS care immediately upon their return to the UK. This struck a cord with me as we are returning in July after being away for 5 1/2 years and I will be 5 months pregnant on our return, so I did a bit of googling and found this link to the citizen advice bureau about NHS heath care which I thought was quite informative and might clear up some of the confusion.

It appears we will be intitled to NHS care immediately providing we are returning to live permenantly but will probably have to prove that is the case as we haven't lived in the UK for the past 12 mths. It does say however that GP's do not have to take you on as a patient, but this seemed to be the case when we lived there before but moved to a new area, it was hard to find a GP. It does seem some people have had issues with this though.
Phew, thats another worry off my mind!! :biggrin: (I hope!)
