Working in Grays
We work right across Grays — RM16, RM17 and RM20 — and in neighbouring Swanscombe and South Ockendon.
Across a large town like Grays, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. For windowless bathrooms in Grays homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. We check the duct route at Grays surveys, because a short, straight run to outside matters more than the fan's headline figure.
Most of Essex 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 backdraught shutter and external grille, so cold air does not blow back in
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
Decisions to make first
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.
Axial, centrifugal or inline
Axial fans suit short, straight runs; centrifugal fans cope better with longer ducts; inline fans sit in the loft and are the quietest in the room.
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.
