My sister is living in shares accommodation. She has just sent me a screen cap of text messages from the live in landlady saying that the tennants can not touch the heating or the boiler. I know it's only September but it's going to get a lot colder. I'm worried as my sister is a very meek person and finds it hard to stand up for herself. Is this allowed?
I should mention though the the land lady lives there she is only there once every few months for a night or so at a time.
