Working in Bishops Stortford
We work right across Bishops Stortford — CM23 — and in neighbouring Harlow and Ware.
In Bishops Stortford, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Bishops Stortford 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. For windowless bathrooms in Bishops Stortford homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Water across much of Hertfordshire 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
- Making good around the fan and checking that it extracts properly at the grille
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
Decisions to make first
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.
Axial, centrifugal or inline
Axial fans suit short, straight runs; centrifugal fans cope better with longer ducts; inline fans sit in the loft and are the quietest in the room.
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.
