What does a bathroom extractor fan cost in Longfield?

Working in Longfield
In Longfield we cover DA3, DA4 and DA13; we also cover Hartley, 0.7 miles away, and Swanscombe.
Longfield gets the same process as anywhere else: a free survey at your home and a written, itemised quote. In Longfield flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. We check the duct route at Longfield surveys, because a short, straight run to outside matters more than the fan's headline figure.
Water across much of Kent 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
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Making good around the fan and checking that it extracts properly at the grille
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
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.
