What does a bathroom extractor fan cost in Wimbledon?
Our guide price for a bathroom extractor fan in Wimbledon is £300–£750 including VAT. We adjust the national guide for London, where prices are typically about 25% above the UK average. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Wimbledon
As well as Wimbledon itself (SW17, SW19 and SW20), we survey in Morden, Mitcham and Putney.
In Wimbledon, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. We check the duct route at Wimbledon surveys, because a short, straight run to outside matters more than the fan's headline figure. In Wimbledon flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Supplies across most of Greater London are very 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
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Making good around the fan and checking that it extracts properly at the grille
- A backdraught shutter and external grille, so cold air does not blow back in
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
Decisions to make first
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.
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.
