Working in Rawtenstall
In Rawtenstall we cover BB4 and OL13; we also cover Haslingden, 1.6 miles away, and Ramsbottom.
Rawtenstall gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For windowless bathrooms in Rawtenstall homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. If your Rawtenstall 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.
Supplies across most of Lancashire are soft. 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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Making good around the fan and checking that it extracts properly at the grille
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
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.
