What the work involves
Many existing fans were never doing their job: undersized, ducted into the loft space, fitted with a flex duct crushed in the joists, or switched off by occupants because they were noisy. The rate a fan delivers through a real duct run is often far lower than the number on the box, which is why we size to the room and test the result.
Ducted to outside through the loft
Insulated duct to a roof, ridge or soffit outlet so warm moist air does not condense in the loft.
Inline fans
A quiet fan in the loft serving one or two ceiling grilles in a shower room or en-suite.

Rules that apply in Wales
In Wales, ventilation follows the Welsh Approved Document F rather than the English version, with building control checking notifiable work. Extract rates and commissioning are checked against the Welsh guidance on every job.
