Frameless structural rooflights in Bexley: what is involved?
We handle frameless structural rooflights across Greater London, including Bexley. 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 architect-led extensions and long slots of light over islands or along party walls.
From Bexley to Bexleyheath, Sidcup and Welling, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Bexley
- Triple glazing
- Heated glass on some ranges
- Low-iron extra-clear glass
- Solar-control coatings
- Shadow-gap or plastered reveal
- Can run along party walls and side returns
- Clean modern detail for architect-led schemes
Things we check at survey
- Large panes need lifting gear and access planning
- The internal finish (plaster, shadow gap) is agreed before order
Do you need permission in Bexley?
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. 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.

Questions about frameless structural rooflights in Bexley
Can it open?
Some frameless designs include a sliding or hinged opening element, but most are fixed. Pair with an opening unit if you need ventilation.
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.
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
Is the survey in Bexley free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Bexley?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
