Sun tunnels & tubular skylights for Port Talbot: the essentials
We handle sun tunnels & tubular skylights across West Glamorgan, including Port Talbot. In short: light pipes that bring daylight to halls and bathrooms with no window. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Typical uses for sun tunnels & tubular skylights include windowless hallways, landings and bathrooms.
From Port Talbot to Briton Ferry, Neath and Maesteg, the same survey-first process applies: measure, specify, fix the price, then fit.

- Integrated electric light

Planning, building control and Port Talbot
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.
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. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
See our building regulations guide for U-values, glazing limits and self-certification.

Sun tunnels & tubular skylights in Port Talbot: 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.
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.
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
Do I need to be at home for the survey in Port Talbot?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Port Talbot free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
