Working in Nelson
We work right across Nelson — BB8, BB9 and BB10 — and in neighbouring Colne and Burnley.
In Nelson, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. For windowless bathrooms in Nelson homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. In Nelson flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
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
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
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.
Timer or humidistat
A timer keeps the fan running after the light goes off. A humidistat starts it whenever moisture rises, which suits rooms where people forget.
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.
