Working in Penarth
As well as Penarth itself (CF64), we survey in Cardiff, Barry and Caerphilly.
Being a smaller town does not change how we work in Penarth: free survey, written quote, one team. Bathroom lighting in Penarth is wired to BS 7671 with RCD protection, tested, and certified when it is finished. We survey Penarth bathrooms before quoting lighting, so the zones are measured from your actual bath and shower.
Water across much of South Glamorgan is moderately hard. Easy-clean glass and good-quality brassware are money well spent. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- IP-rated fittings chosen for each zone, with IP65 downlights over the bath or shower
- RCD protection on the lighting circuit, checked at the consumer unit and added where it is missing
- Fire-rated downlights or fire hoods where the ceiling has to keep its fire resistance
- Cable runs to each fitting, from the loft above or through the ceiling
Decisions to make first
Mirror lighting
An illuminated mirror or mirror cabinet lights the face from the front, which a ceiling light cannot do. Many include a demister pad and a shaver socket.
Integrated or replaceable LED
Integrated LED downlights are slimmer and fully sealed. Fittings with replaceable lamps let you change brightness or colour later.
Rules that apply in Wales
Wales has its own Part P with a wider notifiable list than England, so more bathroom lighting work has to be notified. A registered electrician notifies it and gives you a certificate.
