Working in Chatham
As well as Chatham itself (ME1, ME4 and ME7), we survey in Rochester, Gillingham and Strood.
Across a large town like Chatham, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. In Chatham flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. For windowless bathrooms in Chatham homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Water across much of Kent is very 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
- 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
- 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
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.
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.
