What does a bathroom extractor fan cost in Cambridge?
In Cambridge, a bathroom extractor fan typically costs £265–£650 including VAT, based on East of England prices. Prices in East of England run at about 6% 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 Cambridge
We cover every part of Cambridge, including CB1, CB2 and CB4, and nearby Royston (12.1 miles) and St Ives (12.3 miles).
Cambridge is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. In Cambridge flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. We check the duct route at Cambridge surveys, because a short, straight run to outside matters more than the fan's headline figure.
Water across much of Cambridgeshire is 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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- 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
Decisions to make first
Noise
Compare the stated noise level in decibels. Inline fans and low-speed continuous fans are much quieter in the room than budget axial fans.
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.
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.
