Working in St Helens
In St Helens we cover WA9, WA10, WA11 and 1 more postcode districts; we also cover Prescot, 3.1 miles away, and Ashton in Makerfield.
Across a large town like St Helens, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. For windowless bathrooms in St Helens homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. In St Helens flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Most of Merseyside 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
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Making good around the fan and checking that it extracts properly at the grille
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.
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.
