What the work involves
In England, damp and mould is one of the hazards assessed under the Housing Health and Safety Rating System, and councils can take enforcement action. 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.
Portfolio programmes
Multiple properties surveyed and upgraded to one standard, with a report per address.
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.
