Working in Magherafelt
In Magherafelt we cover BT45 and BT46; we also cover Cookstown, 9.4 miles away, and Ballymena.
Being a smaller town does not change how we work in Magherafelt: free survey, written quote, one team. Fans fitted in Magherafelt bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. In Magherafelt flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Water across much of County Londonderry 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
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- 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
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.
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.
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.
