Working in Antrim
In Antrim we cover BT29 and BT41; we also cover Ballymena, 10.4 miles away, and Newtownabbey.
Antrim gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We check the duct route at Antrim surveys, because a short, straight run to outside matters more than the fan's headline figure. For windowless bathrooms in Antrim homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Supplies across most of County Antrim are 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
- 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
- Making good around the fan and checking that it extracts properly at the grille
Decisions to make first
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.
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.
Rules that apply in Northern Ireland
In Northern Ireland, ventilation is covered by Technical Booklet K, and building control is involved where a new bathroom is formed. There is no Part P, but the fan should be wired, tested and certified to BS 7671.
