In Kempston, a bathroom extractor fan typically costs £265–£650 including VAT, based on East of England prices. Labour costs in East of England put local prices at about 6% above the UK guide figure. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Kempston
We cover every part of Kempston, including MK42, and nearby Bedford (1.9 miles) and Ampthill (6.2 miles).
Being a smaller town does not change how we work in Kempston: free survey, written quote, one team. Fans fitted in Kempston bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. For windowless bathrooms in Kempston homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Most of Bedfordshire 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
- 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
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- A backdraught shutter and external grille, so cold air does not blow back in
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.
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.
