Working in Biggleswade
We work right across Biggleswade — SG18 — and in neighbouring Letchworth Garden City and St Neots.
Being a smaller town does not change how we work in Biggleswade: free survey, written quote, one team. If your Biggleswade bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. Fans fitted in Biggleswade bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Supplies across most of Bedfordshire 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
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- 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
Decisions to make first
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.
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.
