Working in Beckenham
We cover every part of Beckenham, including BR3, SE20 and SE26, and nearby Catford (2.5 miles) and Croydon (3.7 miles).
In Beckenham, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. In Beckenham flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. If your Beckenham bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Water across much of Greater London is 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
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Making good around the fan and checking that it extracts properly at the grille
- A backdraught shutter and external grille, so cold air does not blow back in
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
Decisions to make first
Wall or ceiling
A wall fan on an outside wall is the simplest. A ceiling fan over the shower takes steam away at source but needs ducting through the loft.
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.
