What does a bathroom extractor fan cost in Wishaw?

Working in Wishaw
We cover every part of Wishaw, including ML2, and nearby Larkhall (3 miles) and Motherwell (3.3 miles).
In Wishaw, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. In Wishaw flats, a new vent through an outside wall may need agreement from the other owners or the factor, so we raise it at the survey. We check the duct route at Wishaw surveys, because a short, straight run to outside matters more than the fan's headline figure.
Supplies across most of Lanarkshire are soft. Even so, condensation is the bigger problem in any bathroom, and a properly sized extractor is what deals with it. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- A backdraught shutter and external grille, so cold air does not blow back in
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
Decisions to make first
Axial, centrifugal or inline
Axial fans suit short, straight runs; centrifugal fans cope better with longer ducts; inline fans sit in the loft and are the quietest in the room.
Replacement air
A fan needs air to replace what it removes, so leave a gap of around 10 mm under the door or fit a door grille. A sealed room starves the fan.
Rules that apply in Scotland
In Scotland, the Technical Handbook also uses 15 l/s extract for a bathroom. A replacement fan rarely needs a building warrant, but forming a new bathroom may.
