How we approach ridge & pitched glass roofs in Kensington
We handle ridge & pitched glass roofs across Greater London, including Kensington. In short: dual-pitch glazed roofs for side returns, links and long extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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. Ridge & pitched glass roofs suit side returns, links and long extensions.
From Kensington to Notting Hill, Shepherds Bush and Chelsea, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Solar-control, self-cleaning or tinted glass
- Fixed or retractable shading
- Dual-pitch or mono-pitch
- Opening vents and electric actuators
- Aluminium systems in standard and RAL colours
- Solar-control glass for south-facing slopes
- Maximum daylight for side returns
Before you order: points to check
- Overheating is a real risk on south-facing glass roofs
- Party-wall agreements may apply on terraced houses
Consents for ridge & pitched glass roofs in Kensington
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Ridge & pitched glass roofs in Kensington: questions
Will it be noisy in the rain?
Glass is quieter than polycarbonate. Triple glazing or laminated glass reduces rain noise further.
Can it be partly solid?
Yes — part-glazed, part-insulated roofs balance light and heat.
Do I need a party wall agreement?
If the work affects a party wall or boundary, the Party Wall etc. Act 1996 may apply in England and Wales. We flag this at survey so you can serve notice in time.
Is the survey in Kensington free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Kensington?
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.
