What does a bathroom extractor fan cost in Grantham?
In Grantham, a bathroom extractor fan typically costs £240–£600 including VAT, based on East Midlands prices.

Working in Grantham
As well as Grantham itself (NG31), we survey in Sleaford, Newark on Trent and Melton Mowbray.
Homes in and around Grantham vary, so we look at the floor, the walls and the water system before we price anything. In Grantham flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. For windowless bathrooms in Grantham homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Most of Lincolnshire 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
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- 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
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
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.
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.
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.
