DS2 is about to join in with the virtual open day 'at' the University of Leicester. Looking at their website, they seem to be pretty well organised for the coming September. Re accommodation:
How will social distancing be put in place within the accommodation?
UK Government advice often refers to members of a household. When you move into your accommodation, the other students sharing spaces (kitchen/bathroom) with you are your new household.
You will not be allowed any visitors from outside your household. This includes students from other flats in the same hall. You will have access to large communal spaces and outdoor areas where you can meet people from outside your household while following the social distancing guidelines...

I can't see any mention of those within an individual household only being able to on the same course, but Imay have missed something.
It seriously doesn't seem to be necessary, because there is no requirement for 'real world' household members only to associate with the same people outside the home (as much as one is allowed to), only go to the same shops as each other etc
Interestingly (and quite sensibly), those moving into university accommodation will only be allowed to bring one 'companion' with them and that person will be encouraged to spend as little time as possible within the actual 'household' space.
