Working in Highbury
We cover every part of Highbury, including N1, N5 and N7, and nearby Islington (1 miles) and Holloway (1.1 miles).
In Highbury, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. Fans fitted in Highbury bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. If your Highbury home is listed or in a period terrace, a fan ducted through the loft to a roof vent can avoid a new hole in the front wall, though consent may still apply.
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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
Decisions to make first
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.
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.
