What do frameless structural rooflights in Orpington involve?
For Orpington homes and buildings we offer frameless structural rooflights: minimal glass rooflights with no visible frame from inside. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Think of frameless structural rooflights for architect-led extensions and long slots of light over islands or along party walls.
Orpington is around 21 km from central London, and we survey and fit throughout that part of Greater London, including the BR6 district.
What you can choose
- Triple glazing
- Shadow-gap or plastered reveal
- Heated glass on some ranges
- Butt-jointed runs for long openings
- Low-iron extra-clear glass
- Solar-control and low-iron glass options
- Long, slim or very large formats
Things we check at survey
- The internal finish (plaster, shadow gap) is agreed before order
- Tolerances are tight — the opening must be built square and to size
Consents for frameless structural rooflights in Orpington
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.
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. 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.

Common 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.
Do I need to be at home for the survey in Orpington?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Orpington free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
