What does a bathroom extractor fan cost in Boston?
Our guide price for a bathroom extractor fan in Boston is £240–£600 including VAT. Prices in East Midlands run at about 4% below 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 Boston
As well as Boston itself (PE21), we survey in Spalding, Sleaford and Skegness.
Homes in and around Boston vary, so we look at the floor, the walls and the water system before we price anything. If your Boston bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. In Boston flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
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
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Making good around the fan and checking that it extracts properly at the grille
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
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.
