@Sostenueto, 'has to leave' in what sense? Her accommodation is being closed down? Just not set foot on campus? I am genuinely curious. In London, presumably there are quite a lot of students living in the parental home anyway, rather than in halls,, even in first year.
If the edict is, 'Your accommodation is no longer available to you after this date', how will that work for London students in intercollegiate / anyone in privately managed halls with contracts with multiple institutions or available to be booked outwith a specific university's accommodation office?
DD (Birmingham) has said that she will wait for an email from the university, but if they have sent one yet, she hasn't let on. She had Covid last month, so as I have said, we regard her as low risk anyway.
As for her postgraduate sibling in Bristol, his words were, Ive been basically a shut in since the start of term but no guarantees about what i might've picked up in transit to my in person teaching. Or might, possibly, on the bus in and back to get tested, his flat probably being just slightly too far out for even him to fancy the return walk...
