Working in Peterhead
We work right across Peterhead — AB42 — and in neighbouring Fraserburgh and Inverurie.
Peterhead gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For windowless bathrooms in Peterhead homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. Fans fitted in Peterhead bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Water across much of Aberdeen and Aberdeenshire is soft. Even so, condensation is the bigger problem in any bathroom, and a properly sized extractor is what deals with it. 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
- A backdraught shutter and external grille, so cold air does not blow back in
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
Decisions to make first
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.
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.
Rules that apply in Scotland
In Scotland, the Technical Handbook also uses 15 l/s extract for a bathroom. A replacement fan rarely needs a building warrant, but forming a new bathroom may.
