What does a bathroom extractor fan cost in South Croydon?
In South Croydon, a bathroom extractor fan typically costs £300–£750 including VAT, based on London prices. 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 South Croydon
We work right across South Croydon — CR0, CR2 and CR9 — and in neighbouring Croydon and Purley.
London homes in South Croydon often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. Fans fitted in South Croydon bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. For windowless bathrooms in South Croydon homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Water across much of Greater London 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
- A backdraught shutter and external grille, so cold air does not blow back in
- 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
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.
