Working in Greenford
In Greenford we cover UB1, UB5 and UB6; we also cover Northolt, 1.5 miles away, and Southall.
In Greenford, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. Fans fitted in Greenford bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. For windowless bathrooms in Greenford 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
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
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.
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.
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.
