What the work involves
Awaab's Law already sets strict timescales for social landlords, and the Renters' Rights Act provides for similar duties to be extended to private renting. Wales, Scotland and Northern Ireland have their own standards, but the practical answer is the same: moisture has to be extracted.
Fan upgrade per room
Humidity-controlled or continuous fans in kitchens and bathrooms, ducted to outside.
Rental package
A PIV unit plus two humidity fans: a typical fix for a damp 2 to 3 bed rental.
