Working in Dagenham
We cover every part of Dagenham, including RM8, RM9 and RM10, and nearby Becontree (1.6 miles) and Romford (1.9 miles).
London homes in Dagenham often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. In Dagenham flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. We check the duct route at Dagenham surveys, because a short, straight run to outside matters more than the fan's headline figure.
Supplies across most of Greater London are very 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
- Making good around the fan and checking that it extracts properly at the grille
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- 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.
