Working in Amersham on the Hill
We cover every part of Amersham on the Hill, including HP5, HP6 and HP7, and nearby Amersham (0.7 miles) and Chesham (1.8 miles).
Amersham on the Hill gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For windowless bathrooms in Amersham on the Hill homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. Fans fitted in Amersham on the Hill bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Most of Buckinghamshire has hard water. Steam carries that scale onto mirrors and glass, so a fan that clears the room quickly helps on both counts. 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 backdraught shutter and external grille, so cold air does not blow back in
- 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
Decisions to make first
Noise
Compare the stated noise level in decibels. Inline fans and low-speed continuous fans are much quieter in the room than budget axial fans.
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.
