Working in Bicester
In Bicester we cover OX6 and OX26; we also cover Oxford, 11.1 miles away, and Cowley.
Homes in and around Bicester vary, so we look at the floor, the walls and the water system before we price anything. We check the duct route at Bicester surveys, because a short, straight run to outside matters more than the fan's headline figure. For windowless bathrooms in Bicester homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Supplies across most of Oxfordshire 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
- 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
- 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
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.
Timer or humidistat
A timer keeps the fan running after the light goes off. A humidistat starts it whenever moisture rises, which suits rooms where people forget.
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.
