What do sun tunnels & tubular skylights in Porthcawl involve?
Sun tunnels & tubular skylights in Porthcawl means light pipes that bring daylight to halls and bathrooms with no window. We cover the CF36 district and the rest of Mid Glamorgan, with a survey before any price is fixed.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Typical uses for sun tunnels & tubular skylights include small internal rooms where a full rooflight will not fit.
From Porthcawl to Bridgend, Port Talbot and Maesteg, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Porthcawl
Planning rules in Wales are tighter than in England for rooflights: Class C rights do not apply in conservation areas, National Parks or AONBs, so a rooflight there needs planning permission. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
See our building regulations guide for U-values, glazing limits and self-certification.
