Working in Keynsham
As well as Keynsham itself (BS31), we survey in Kingswood, Mangotsfield and Bishopsworth.
Being a smaller town does not change how we work in Keynsham: free survey, written quote, one team. Fans fitted in Keynsham bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. If your Keynsham bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Most of Somerset 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
- 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
- Making good around the fan and checking that it extracts properly at the grille
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.
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.
