Working in Chichester
In Chichester we cover PO19; we also cover Bognor Regis, 5.8 miles away, and Emsworth.
In Chichester, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. We check the duct route at Chichester surveys, because a short, straight run to outside matters more than the fan's headline figure. In Chichester flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Most of West Sussex 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
- 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
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
Decisions to make first
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.
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.
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.
