What do sun tunnels & tubular skylights involve?
Sun tunnels & tubular skylights in Gwent means light pipes that bring daylight to halls and bathrooms with no window. Every quote follows a survey of the roof and the room below.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting.

Planning and building rules in Wales
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Common questions
How much light does a sun tunnel give?
A good rigid tunnel on a bright day lights a hallway well. Output depends on tube diameter, length and the number of bends.
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
Do sun tunnels need planning permission?
Usually not on a house, provided the dome does not project too far and the property is not listed. Check if you live in a conservation area or a flat.
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
Do I need to be at home for the survey in Gwent?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
