Working in Birkenhead
In Birkenhead we cover CH41, CH42, CH43 and 4 more postcode districts; we also cover Liverpool, 1.9 miles away, and Bootle.
Birkenhead is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. We check the duct route at Birkenhead surveys, because a short, straight run to outside matters more than the fan's headline figure. In Birkenhead flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Water across much of Merseyside is 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
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- 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
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
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.
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.
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.
