What does a bathroom extractor fan cost in Brent?
For Brent, our guide range for a bathroom extractor fan is £300 to £750 including VAT. Prices in London run at about 25% 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 Brent
We cover every part of Brent, including HA0, HA9, NW2 and 2 more postcode districts, and nearby Harrow (2.2 miles) and Bushey (6.7 miles).
In Brent, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. For windowless bathrooms in Brent homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. In Brent flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Most of Greater London has very hard water. 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
- Making good around the fan and checking that it extracts properly at the grille
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- A check of the room, any existing fan or vent, and the shortest route to the outside
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.
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.
