What does a bathroom extractor fan cost in Epsom?
In Epsom, a bathroom extractor fan typically costs £280–£650 including VAT, based on South East England prices. Prices in South East England run at about 12% 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 Epsom
We work right across Epsom — KT17 and KT19 — and in neighbouring Ewell and Banstead.
Homes in and around Epsom vary, so we look at the floor, the walls and the water system before we price anything. If your Epsom bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. If your Epsom 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.
Most of Surrey has 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
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- Making good around the fan and checking that it extracts properly at the grille
- A check of the room, any existing fan or vent, and the shortest route to the outside
Decisions to make first
Axial, centrifugal or inline
Axial fans suit short, straight runs; centrifugal fans cope better with longer ducts; inline fans sit in the loft and are the quietest in the room.
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.
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.
