What do frameless structural rooflights in London involve?
Our frameless structural rooflights service in London covers minimal glass rooflights with no visible frame from inside. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
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. Typical uses for frameless structural rooflights include architect-led extensions and long slots of light over islands or along party walls.
London is the main town we list in Greater London; we also cover nearby Pimlico and Islington.

Consents for frameless structural rooflights in London
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. 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.
Read the planning permission guide before you commit to a design.

Frameless structural rooflights in London: questions
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.
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.
