From the article "These would be complemented by 1,000 “step down beds”, some of the supplied by the opening of the capital’s Nightingale hospital," so sounds like it's not in use yet.

The big problem with the nightingale hospitals is that there were no staff to run them, and hospitals are understaffed as it is with people of sick or isolating due to the governments approach of vaccinating their voters first ahead of medical staff.

Even if they were used in the first wave it was in the expectation that any hospitals sending patients there would also send staff to look after them, which was never realistic.

You can hire a hall and stick a bed in it, but if there’s no one to look after the sick person in it they don’t have much of a chance.

I still think they were really intended to be overflow morgues rather than proper hospitals, or at least solely palliative.

You can't build a hospital like that in a week, and there are no staff.

They got shut down, the one at Excel had like 4 patients in it and a handful of nurses.

Doesn't exist anymore :)
