Working in Cardiff
In Cardiff we cover CF10, CF11 and CF24; we also cover Penarth, 2.9 miles away, and Caerphilly.
In a city the size of Cardiff, parking and access for a skip are worth sorting before the start date — we will ask at the survey. In Cardiff flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. Fans fitted in Cardiff bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Supplies across most of South Glamorgan are moderately hard. Scale is a minor issue next to condensation, which is what a properly sized extractor fan is for. 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 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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
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 Wales
Wales has its own Part F with similar extract rates, and its own Part P, under which new fan wiring in a bathroom is notifiable.
