Sun tunnels & tubular skylights in Caerphilly: what is involved?
Our sun tunnels & tubular skylights service in Caerphilly covers light pipes that bring daylight to halls and bathrooms with no window. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
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.
We work across Gwent, including Caerphilly, and in neighbouring towns such as Risca and Pontypridd. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Ventilation adaptor
- Integrated electric light
- Pitched or flat-roof flashings
- Diffusers in several sizes
- Insulated tube sections
- Works on pitched and flat roofs
- Optional ventilation or lighting kit on some models
Things we check at survey
- Tube runs need insulation in cold lofts to limit condensation
- Not a substitute for a habitable-room window
Consents for sun tunnels & tubular skylights in Caerphilly
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
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. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
Read the planning permission guide before you commit to a design.
