What does a bathroom extractor fan cost in Croydon?
Guide price in Croydon: £300–£750 including VAT, depending on the room and what you choose. Labour costs in London put local prices at about 25% above the UK guide figure. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Croydon
As well as Croydon itself (CR0, CR2, CR5 and 5 more postcode districts), we survey in Mitcham, Purley and Streatham.
In Croydon, 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 Croydon homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. In Croydon 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
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
Decisions to make first
Timer or humidistat
A timer keeps the fan running after the light goes off. A humidistat starts it whenever moisture rises, which suits rooms where people forget.
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.
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.
