What does a bathroom extractor fan cost in Sandhurst?
Our guide price for a bathroom extractor fan in Sandhurst is £280–£650 including VAT. Prices in South East England run at about 12% above 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 Sandhurst
We work right across Sandhurst — GU47 — and in neighbouring Crowthorne and Yateley.
Sandhurst gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We check the duct route at Sandhurst surveys, because a short, straight run to outside matters more than the fan's headline figure. Fans fitted in Sandhurst bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Water across much of Berkshire is hard. Steam carries that scale onto mirrors and glass, so a fan that clears the room quickly helps on both counts. 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 backdraught shutter and external grille, so cold air does not blow back in
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
Decisions to make first
Intermittent or continuous
An intermittent fan runs during and after use. A continuous fan runs quietly all the time at a low rate and boosts when humidity rises.
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.
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.
