Frameless structural rooflights for Croydon: the essentials
Thinking about frameless structural rooflights in Croydon? The short answer: minimal glass rooflights with no visible frame from inside. The longer answer depends on your roof, which is why we survey before we price.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. In Croydon, as anywhere, frameless structural rooflights are the usual choice for rooms where you want sky without a visible frame.
Neighbouring towns include South Croydon (2 km) and Wallington (4 km). We offer a survey date when we reply to your enquiry.

- Butt-jointed runs for long openings

Planning and building rules for Croydon
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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.

Common questions
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 is it lifted onto the roof?
Larger panes go up with a vacuum lifter, a hoist or a crane. We plan access at survey.
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 the survey in Croydon free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Croydon?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
