Shielding was always voluntary and just a recommendation. As a programme it was paused on August 15th in Wales and August 1st in the rest of the U.K. As a result there is no longer any government support to continue shielding beyond this time.
Doctors can still recommend that individual patients continue to isolate, but this is purely a recommendation from a doctor, is unrelated to the governments shielding programmes, and therefore comes with no support to be able to do so.
Supermarkets have agree to continue priority access to the most vulnerable people, although since shielding ended Tesco have increased their delivery price for the those with priority (£2 to £5.50 to match their regular price), while Asda have converted it to a delivery pass which expires on October 22nd.
But that supermarket is the only concession available, if an employer requires you to work you have no basis to refuse if they are "covid-secure".
Anyway, I usually have my fortnightly hospital blood tests on Fridays, but could not attend last week due to a clinic appointment. So I went today, half an hour by bus, and when i saw how busy it was I just came straight home as I did not feel safe.
The phlebotomy waiting room is pretty small, so with seats taped over there is not room for many people in there that they had people queueing in the hall. Unsurprisingly the hall is smaller still, and has people passing by. There are no windows with rooms on either side so it is quite enclosed, and the spacing in the queue was only about 1ft.
I was shielding due to being immunosuppressed for arthritis, an interstitial lung disease, and uncontrolled diabetes. So I am not going to start taking risks, especially now that the spread is rising fast. Whilst I am no longer strictly shielding, yesterday was the only time I have been out or met anyone other than for medical reasons (someone came to fix a puncture, so I never went further than my local street).
Otherwise I am still doing my shopping online, and having any deliveries unattended so I only go out to bring things into my flat after other people have left. I am still avoiding contact with other people as much as possible.
