Frameless structural rooflights for Bromley: the essentials
Frameless structural rooflights in Bromley means minimal glass rooflights with no visible frame from inside. We cover the BR1 district and the rest of Greater London, with a survey before any price is fixed.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Think of frameless structural rooflights for architect-led extensions and long slots of light over islands or along party walls.
From Bromley to Beckenham, Catford and Eltham, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose

Things we check at survey

Consents for frameless structural rooflights in Bromley
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Frameless structural rooflights in Bromley: questions
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
Will I see the edge of the glass?
From inside, the reveal is finished up to the glass so the edge is hidden. From outside you will see the glass and its edge seal.
Is frameless glass as strong as a framed rooflight?
Yes — it is structural glass designed for the job. The support is hidden rather than missing.
How do I book a survey in Bromley?
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 Bromley?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
