Working in Canterbury
As well as Canterbury itself (CT1, CT2, CT5 and 1 more postcode districts), we survey in Whitstable, Herne Bay and Faversham.
In a city the size of Canterbury, parking and access for a skip are worth sorting before the start date — we will ask at the survey. If your Canterbury bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. If your Canterbury home is listed or in a period terrace, a fan ducted through the loft to a roof vent can avoid a new hole in the front wall, though consent may still apply.
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
- 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
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
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.
