What does a bathroom extractor fan cost in Chelsea?
In Chelsea, 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 Chelsea
We cover every part of Chelsea, including SW3, SW7 and SW10, and nearby Battersea (1.1 miles) and Fulham (1.4 miles).
London homes in Chelsea often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If your Chelsea home is listed or in a period terrace, a fan ducted through the loft to a roof vent can avoid a new hole in the front wall, though consent may still apply. For windowless bathrooms in Chelsea homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
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
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- 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.
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.
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.
