Working in Harlow
In Harlow we cover CM17, CM18, CM19 and 1 more postcode districts; we also cover Hoddesdon, 5.4 miles away, and Ware.
Across a large town like Harlow, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. If your Harlow bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. For windowless bathrooms in Harlow homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Supplies across most of Essex are 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
- 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
Decisions to make first
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.
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.
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.
