Forgive me if this is a daft question but I am moving into a rented house on Monday (first timer, so it's all new to me!) we had planned to get our contents insurance soon after moving in once we actually know the value of the contents (we currently own a bed, some electricals and that's about it!) - but we got a letter from the agents today telling us we needed to bring our contents insurance cover note on Monday along with various other things (copy of passport, deposits etc) that are required before we can sign.
Is this normal? Can they actually refuse to let us move in if we don't have one?
