What does a bathroom extractor fan cost in Greenock?
In Greenock, a bathroom extractor fan typically costs £240–£600 including VAT, based on Scotland prices. Prices in Scotland run at about 4% below the national guide, mainly because of labour rates. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Greenock
As well as Greenock itself (PA14, PA15, PA16 and 1 more postcode districts), we survey in Helensburgh, Dunoon and Vale of Leven.
In Greenock, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. We check the duct route at Greenock surveys, because a short, straight run to outside matters more than the fan's headline figure. For windowless bathrooms in Greenock homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Water across much of Renfrewshire and Inverclyde is 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
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- A check of the room, any existing fan or vent, and the shortest route to the outside
- 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.
