Working in Thamesmead
We work right across Thamesmead — DA18, SE2 and SE28 — and in neighbouring Barking and Welling.
London homes in Thamesmead often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. For windowless bathrooms in Thamesmead homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. Fans fitted in Thamesmead bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Most of Greater London 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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- 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
- A backdraught shutter and external grille, so cold air does not blow back in
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.
