Working in Chesterfield
As well as Chesterfield itself (S40 and S41), we survey in Staveley, Dronfield and Sheffield.
Chesterfield has a wide mix of house ages, so the survey is where we spot old lead pipework, weak joists or a tight soil stack. Fans fitted in Chesterfield bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. If your Chesterfield bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Supplies across most of Derbyshire are moderately hard. Scale is a minor issue next to condensation, which is what a properly sized extractor fan is for. 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
- 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
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.
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.
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.
