Working in Barking
As well as Barking itself (IG11, RM6, RM8 and 2 more postcode districts), we survey in Ilford, Becontree and Dagenham.
In Barking, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. Fans fitted in Barking bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. For windowless bathrooms in Barking homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
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
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Making good around the fan and checking that it extracts properly at the grille
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
Decisions to make first
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.
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.
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.
