Thank you to Ski School, who has provided more clarity than the receptionists at my GPs.
I dutifully rung my GP to no avail. I had a text message over two weeks ago which said I had been identified in an at-risk group and refer to self distancing on the govt. website etc.
Receptionist said if I'd received this text, that is all I would receive and to refer to govt. website again.
What puzzles me is that on the Govt. website it tells you to contact your GP if you have not received a letter.
All very confusing, but I certainly don't want to waste anyone's time.
Has anyone done a bit better than me, by ringing their GP or have they had a similar response from a GP's receptionist?
