What do frameless structural rooflights in Catford involve?
Our frameless structural rooflights service in Catford covers minimal glass rooflights with no visible frame from inside. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written 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. Frameless structural rooflights suit architect-led extensions and long slots of light over islands or along party walls.
From Catford to Lewisham, Blackheath and Greenwich, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Catford
- Butt-jointed runs for long openings
- Heated glass on some ranges
- Triple glazing
- Shadow-gap or plastered reveal
- Solar-control coatings
- Double or triple glazed structural units
- Clean modern detail for architect-led schemes
Things we check at survey
- Large panes need lifting gear and access planning

Planning and building rules for Catford
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about frameless structural rooflights in Catford
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 frameless glass as strong as a framed rooflight?
Yes — it is structural glass designed for the job. The support is hidden rather than missing.
Can you work alongside my builder in Catford?
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 Catford?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
