How we approach frameless structural rooflights in Streatham
We handle frameless structural rooflights across Greater London, including Streatham. 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.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Frameless structural rooflights suit rooms where you want sky without a visible frame.
From Streatham to Balham, Clapham and Mitcham, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Streatham
- Heated glass on some ranges
- Solar-control coatings
- Butt-jointed runs for long openings
- Triple glazing
- Low-iron extra-clear glass
- Can run along party walls and side returns
- Clean modern detail for architect-led schemes
Things we check at survey
- Tolerances are tight — the opening must be built square and to size
- The internal finish (plaster, shadow gap) is agreed before order
Do you need permission in Streatham?
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.
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.
