Working in Chadderton
As well as Chadderton itself (OL1, OL8 and OL9), we survey in Oldham, Royton and Middleton.
Homes in and around Chadderton vary, so we look at the floor, the walls and the water system before we price anything. Fans fitted in Chadderton bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. We check the duct route at Chadderton surveys, because a short, straight run to outside matters more than the fan's headline figure.
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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Making good around the fan and checking that it extracts properly at the grille
- A backdraught shutter and external grille, so cold air does not blow back in
Decisions to make first
Intermittent or continuous
An intermittent fan runs during and after use. A continuous fan runs quietly all the time at a low rate and boosts when humidity rises.
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.
