What does a bathroom extractor fan cost in Esher?

Working in Esher
In Esher we cover KT7 and KT10; we also cover East Molesey, 2.1 miles away, and West Molesey.
In Esher, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. We check the duct route at Esher surveys, because a short, straight run to outside matters more than the fan's headline figure. If your Esher bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Water across much of Surrey is hard. 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
- A backdraught shutter and external grille, so cold air does not blow back in
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
Decisions to make first
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.
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.
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.
