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.

Questions about ventilation for landlords and letting agents in Wiltshire
Which rules apply to ventilation in Wiltshire?
In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
Is a landlord responsible for condensation and mould?
A landlord is responsible for the condition of the property, including adequate ventilation and heating, and serious damp and mould can be a hazard under housing law. Tenants also have to use the home reasonably, but ventilation that works without effort removes most disputes.
What is the best ventilation for a rental property?
For most rentals, humidity-controlled or continuous extract fans in the wet rooms plus a PIV unit gives reliable results that tenants cannot easily switch off. It typically costs £1,495 to £2,695 including VAT for a 2 to 3 bed home.
Which towns in Wiltshire do you cover?
All of Wiltshire, including Salisbury, Trowbridge, Chippenham, Melksham and Warminster. If your town is not listed, send the postcode and we will confirm.
