Hello, i live in the converted attic part of a building with 4 other flats. The freeholders have decided to replace the entire roof. Causing a large amount of dust coming through into the flat making my bathroom and kitchen unusable my bed and new sofa are covered in it. My health is declining from the dust and noise of the work. I have been forced to live out of bags as I cannot live there anymore and sleep on friends sofas. My landlord agrees I should not pay rent while the work is carried out but he is not willing to give back the rent I have already paid as he wants to get it back from the freeholders first. Can he do this? Please help.
