Working in Muswell Hill
We work right across Muswell Hill — N2, N8 and N10 — and in neighbouring Wood Green and Archway.
London homes in Muswell Hill often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. For windowless bathrooms in Muswell Hill homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. Fans fitted in Muswell Hill bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Water across much of Greater London is very 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
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- Making good around the fan and checking that it extracts properly at the grille
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.
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.
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.
