Working in Bletchley
We cover every part of Bletchley, including MK1, MK2 and MK3, and nearby Milton Keynes (3.5 miles) and Leighton Buzzard (6.2 miles).
Homes in and around Bletchley vary, so we look at the floor, the walls and the water system before we price anything. Fans fitted in Bletchley bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. For windowless bathrooms in Bletchley homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
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
- 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 check of the room, any existing fan or vent, and the shortest route to the outside
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
Decisions to make first
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.
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.
