Working in Poole
We cover every part of Poole, including BH12, BH13, BH14 and 3 more postcode districts, and nearby Bournemouth (4.6 miles) and Ferndown (7.4 miles).
Across a large town like Poole, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. In Poole flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. For windowless bathrooms in Poole homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Water across much of Dorset is 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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- 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
Wall or ceiling
A wall fan on an outside wall is the simplest. A ceiling fan over the shower takes steam away at source but needs ducting through the loft.
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.
