What do walk-on rooflights in Swansea involve?
We handle walk-on rooflights across West Glamorgan, including Swansea. In short: structural glass you can stand on, set flush into terraces and floors. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Think of walk-on rooflights for roof terraces, balconies and floors above basements.
Swansea is the main town we list in West Glamorgan; we also cover nearby Briton Ferry and Gorseinon.
What you can choose
- Internal floor panels between storeys
- Heated or self-cleaning glass on some ranges
- Fixed or with privacy interlayer
- Double or triple glazed with a structural top pane
- Anti-slip frit or etched top surface
- Flush with paving or decking — no trip edge
- Light below without losing usable terrace space
Before you order: points to check
- Structural support and the design load must be confirmed by the manufacturer or an engineer
- Drainage around the unit needs planning so water does not pond on the glass
Do you need permission in Swansea?
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. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. 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.

Common questions
Is the glass slippery?
Walk-on glass has an anti-slip finish, usually a ceramic frit or etched pattern. Like any outdoor surface it needs cleaning to stay effective.
Can it be used inside the house?
Yes. Internal walk-on panels pass light from an upper floor or ground floor to a basement below.
Can you see through it?
Clear glass can be seen through from both sides. A privacy interlayer or patterned frit keeps the light while obscuring the view.
How do I book a survey in Swansea?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Swansea?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
