Working in Redhill
As well as Redhill itself (RH1 and RH2), we survey in Reigate, Horley and Caterham.
In Redhill, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. Fans fitted in Redhill bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. For windowless bathrooms in Redhill homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Most of Surrey has 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
- A check of the room, any existing fan or vent, and the shortest route to the outside
- 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
Replacement air
A fan needs air to replace what it removes, so leave a gap of around 10 mm under the door or fit a door grille. A sealed room starves the fan.
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.
