Working in East Grinstead
As well as East Grinstead itself (RH19), we survey in Horley, Crawley and Crowborough.
Homes in and around East Grinstead vary, so we look at the floor, the walls and the water system before we price anything. In East Grinstead flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. Fans fitted in East Grinstead bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Supplies across most of West Sussex are 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
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- 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
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
Decisions to make first
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.
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.
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.
