What does a bathroom extractor fan cost in Penarth?
In Penarth, a bathroom extractor fan typically costs £230–£550 including VAT, based on Wales prices. Prices in Wales run at about 7% below the national guide, mainly because of labour rates. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Penarth
As well as Penarth itself (CF64), we survey in Cardiff, Barry and Caerphilly.
Penarth gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For windowless bathrooms in Penarth homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. Fans fitted in Penarth bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Water across much of South Glamorgan is 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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Making good around the fan and checking that it extracts properly at the grille
- A backdraught shutter and external grille, so cold air does not blow back in
Decisions to make first
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.
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.
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.
