Working in Wembley
We work right across Wembley — HA0, HA9 and UB6 — and in neighbouring Brent and Harrow.
London homes in Wembley often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. We check the duct route at Wembley surveys, because a short, straight run to outside matters more than the fan's headline figure. In Wembley flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Most of Greater London has very 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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
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.
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.
