Working in Nailsea
In Nailsea we cover BS48; we also cover Portishead, 3.5 miles away, and Clevedon.
Nailsea gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For windowless bathrooms in Nailsea homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. Fans fitted in Nailsea bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Supplies across most of Somerset 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 check of the room, any existing fan or vent, and the shortest route to the outside
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- 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.
