What does a bathroom extractor fan cost in Mirfield?
As a guide, budget £230 to £550 including VAT for a bathroom extractor fan in Mirfield; your written quote will pin it down. Prices in Yorkshire and the Humber run at about 7% 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 Mirfield
In Mirfield we cover WF14; we also cover Liversedge, 2.2 miles away, and Heckmondwike.
Mirfield gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We check the duct route at Mirfield surveys, because a short, straight run to outside matters more than the fan's headline figure. In Mirfield flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Most of West Yorkshire is supplied with soft water. 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
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
Decisions to make first
Wall or ceiling
A wall fan on an outside wall is the simplest. A ceiling fan over the shower takes steam away at source but needs ducting through the loft.
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 England
In England, Approved Document F sets bathroom extract at 15 l/s for an intermittent fan or 8 l/s for continuous extract. Wiring a new fan alters a circuit in a room with a bath or shower, so it is notifiable under Part P.
