Back in the proper lockdown you could move house or move into someone elses houses for at least a week or more for a valid reason like the house being uninhabitable or domestic abuse.
Simply have your lad fill the bog up till the pipe bursts, claim it’s uninhabitable in a letter and email to the university and leave.
Produce a copy of the letter to any copper who turns up on your door and tell them to jog on.
Having said which, it would have been even more obvious to the people in charge of universities, but they just lied and obfuscated to save their own skins. They deliberately misled the very people who are paying them stacks of money for an education. Rather than looking after their charges, the Unis shafted them.
Yup, people have been saying this for years and now Tory papers are shocked…shocked I tell you that Universities are being run like racketeering rings….now middle class kids are being ripped off.
