I remember my housing trust saying they would not carry out my repairs if I had rent arrears. And of course I complained strongly about it at the time... "Too many repairs" might be another way nasty way the landlords have to intimidate tenants not to have repairs carried out... If your landlord does not carry out your repairs, withold rent into a separate bank account. have the repairs done privately and pay them with the rent you are witholding. keep all the receipts and any paperwork... Make sure also you can prove possibly in writing that you have reported your repairs more than once to your landlorda and they have not responded or refused.
