Working in Hartley
We cover every part of Hartley, including DA3, and nearby Longfield (0.7 miles) and Swanscombe (4.2 miles).
Hartley gets the same process as anywhere else: a free survey at your home and a written, itemised quote. Fans fitted in Hartley bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. In Hartley flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
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 backdraught shutter and external grille, so cold air does not blow back in
- 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.
Intermittent or continuous
An intermittent fan runs during and after use. A continuous fan runs quietly all the time at a low rate and boosts when humidity rises.
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.
