Working in Bolton
We work right across Bolton — BL1, BL2, BL3 and 2 more postcode districts — and in neighbouring Farnworth and Westhoughton.
Across a large town like Bolton, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. We check the duct route at Bolton surveys, because a short, straight run to outside matters more than the fan's headline figure. In Bolton flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Most of Greater Manchester is supplied with soft water. Even so, condensation is the bigger problem in any bathroom, and a properly sized extractor is what deals with it. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A backdraught shutter and external grille, so cold air does not blow back in
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
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.
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.
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.
