Working in Basingstoke
We work right across Basingstoke — RG21, RG22, RG23 and 1 more postcode districts — and in neighbouring Tadley and Alton.
Basingstoke has a wide mix of house ages, so the survey is where we spot old lead pipework, weak joists or a tight soil stack. In Basingstoke flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. If your Basingstoke 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.
Most of Hampshire has hard water. 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
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
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.
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.
