Thanks for the advice. I have seen a draft contract and it has been written such that DD only signs for her room. I would be joint & several with her. I also spoke to the agent who said just to redact anything personal when I sent the stuff off.
The contract does say not to dry clothes on radiators or to dry them in such a way that can be seen from outside the house. Yet there is a washing line in the courtyard. I'm going to get DD to check whether or not they can use it - seems a bit strange to me but we live in a hamlet with a big garden and only ever dry stuff outside and nobody can see that.
3rd year student DD1 has had a couple of her tutorials moved due to strikes but neither DD has had too much disruption luckily. One of DD1's school friends was at a uni in Italy for her 3rd year. She was able to get out and is now with a friend in France wondering how she's going to get enough experience of Italian. I just hope nothing spreads further here til both DDs are safely home...
