Working in Aylesbury
We work right across Aylesbury — HP19, HP20 and HP21 — and in neighbouring Leighton Buzzard and Berkhamsted.
In Aylesbury, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. For windowless bathrooms in Aylesbury homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. Fans fitted in Aylesbury bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Supplies across most of Buckinghamshire are hard. 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
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- A backdraught shutter and external grille, so cold air does not blow back in
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
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.
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.
