How we approach frameless structural rooflights in Kensington
Our frameless structural rooflights service in Kensington 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 rooms where you want sky without a visible frame.
Kensington is around 5 km from central London, and we survey and fit throughout that part of Greater London, including the W8 district.

Planning and building rules for Kensington
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. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Questions about frameless structural rooflights in Kensington
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
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.
Do I need to be at home for the survey in Kensington?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Kensington?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
