What does a bathroom extractor fan cost in Maidstone?

The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Maidstone
As well as Maidstone itself (ME14, ME15 and ME16), we survey in Chatham, Rochester and Gillingham.
Across a large town like Maidstone, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. In Maidstone flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. If your Maidstone bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Most of Kent 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
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Making good around the fan and checking that it extracts properly at the grille
Decisions to make first
Intermittent or continuous
An intermittent fan runs during and after use. A continuous fan runs quietly all the time at a low rate and boosts when humidity rises.
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.
