What ventilation for landlords and letting agents involves
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. Jobs can be booked between tenancies or arranged with tenants in occupation, and every visit ends with photos and airflow readings you can keep on file.
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.
HMO ventilation
Extract for every kitchen and shower room, often with continuous fans tenants cannot switch off.
