Frameless structural rooflights in Chelsea: what is involved?
We handle frameless structural rooflights across Greater London, including Chelsea. 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of frameless structural rooflights for rooms where you want sky without a visible frame.
Chelsea sits about 2 km from Battersea and 2 km from Wandsworth, and we cover the whole SW10 postcode district and the roads in between.

- Large panes need lifting gear and access planning
Planning, building control and Chelsea
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. 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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about frameless structural rooflights in Chelsea
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.
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
