Frameless structural rooflights for Swanley: the essentials
We handle frameless structural rooflights across Kent, including Swanley. In short: minimal glass rooflights with no visible frame from inside. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of frameless structural rooflights for architect-led extensions and long slots of light over islands or along party walls.
We work across Kent, including Swanley, and in neighbouring towns such as Bexley and Orpington. Access, parking and how the glass reaches the roof are all checked at the survey.

Before you order: points to check

Do you need permission in Swanley?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.

Yes — it is structural glass designed for the job. The support is hidden rather than missing.

Can it open?
Some frameless designs include a sliding or hinged opening element, but most are fixed. Pair with an opening unit if you need ventilation.
Can you work alongside my builder in Swanley?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Swanley free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
