Working in Llantwit Major
We work right across Llantwit Major — CF61 — and in neighbouring Bridgend and Barry.
Llantwit Major gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We check the duct route at Llantwit Major surveys, because a short, straight run to outside matters more than the fan's headline figure. If your Llantwit Major home is listed or in a period terrace, a fan ducted through the loft to a roof vent can avoid a new hole in the front wall, though consent may still apply.
Most of South Glamorgan has moderately hard water. 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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- A backdraught shutter and external grille, so cold air does not blow back in
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.
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.
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.
