Can I have 4 friends over one evening (socially distanced - we have open plan downstairs so space isn’t an issue), while DH & 3 kids are upstairs? The kids would be sleeping and DH either watching TV or working. So in the house would be a total of 9 people but on totally different floors and there are toilets on both floors so is it several “groups” so no reason for anyone to come into contact with anyone else.
It seems a bit ridiculous when if we went to a pub there could be another who knows how many people there sitting in groups just a metre or so away!
So would this be legal or illegal?
