Frameless structural rooflights in Edmonton: what is involved?
Frameless structural rooflights in Edmonton means minimal glass rooflights with no visible frame from inside. We cover the N18 district and the rest of Greater London, with a survey before any price is fixed.
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. Typical uses for frameless structural rooflights include architect-led extensions and long slots of light over islands or along party walls.
Edmonton sits about 3 km from Tottenham and 3 km from Enfield, and we cover the whole N18 postcode district and the roads in between.

Planning and building rules for Edmonton
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about frameless structural rooflights in Edmonton
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.
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.
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
Can you work alongside my builder in Edmonton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Edmonton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
