What do walk-on rooflights in Llanelli involve?
For Llanelli homes and buildings we offer walk-on rooflights: structural glass you can stand on, set flush into terraces and floors. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. In Llanelli, as anywhere, walk-on rooflights are the usual choice for roof terraces, balconies and floors above basements.
Llanelli is the main town we list in Dyfed; we also cover nearby Gorseinon and Swansea.
What you can choose
- Fixed or with privacy interlayer
- Integrated in paving pedestals or a timber deck
- Anti-slip frit or etched top surface
- Internal floor panels between storeys
- Heated or self-cleaning glass on some ranges
- Light below without losing usable terrace space
- Flush with paving or decking — no trip edge
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 Llanelli?
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. 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.
Read the planning permission guide before you commit to a design.

Walk-on rooflights in Llanelli: questions
Does it need a structural engineer?
Often, yes. Where the unit sits on new or altered structure, an engineer confirms the support and the manufacturer confirms the glass.
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.
Will it sit flush with my paving?
Yes — the unit is set on its own upstand so the glass finishes level with the surrounding paving or decking.
Can you work alongside my builder in Llanelli?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Llanelli?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
