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. We work with individual landlords, portfolio landlords, HMO owners and letting agents.
HMO ventilation
Extract for every kitchen and shower room, often with continuous fans tenants cannot switch off.
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.

Rules in England
