UK entry clearance visa confusion.

[SYH]

I know that when my husband entered on ILE he had to enter the UK within 6 months of the issue of the visa and that the visa was stamped as valid for the life of the passport. We certainly had to show it to obtain NHS care in the first year we were here.

Guess it depends on where you live because no one asked me outside of London but the one time I went to a gp in london, the nurse asked but didn't require any documentation

Since when are GP's surgeries checking people's passports and visas? I've never been asked by any hospital or GP to see my visa or passport (before I became a naturalised British citizen). Is this something new?

Yeah actually they specifically said that to me on the phone because I wanted to see GP for an urgent matter but I am only in the area temporarily. I was really surprised and annoyed because cmon really, for a quick visit, it is not going to break the bank. If you get a course of treatment, then I think you need to be sure.
I also think this may be big city focused so for London, they are getting particular.
