Hinged roof access rooflights for Kensington: the essentials
Thinking about hinged roof access rooflights in Kensington? The short answer: hinged glazed hatches over a stair or ladder for roof terrace access. The longer answer depends on your roof, which is why we survey before we price.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Hinged roof access rooflights suit occasional roof access that also lights the stair.
We work across Greater London, including Kensington, and in neighbouring towns such as Notting Hill and Shepherds Bush. Access, parking and how the glass reaches the roof are all checked at the survey.
Choices for your Kensington project
- Double or triple glazing
- Rain sensor on electric versions
- Grab rail or handle inside
- Manual gas-strut or electric opening
- Hinge side to suit the stair
- Insulated frame and double or triple glazing
- Lockable from inside
What to check first
- Roof edges people reach may need guarding
- The lid must open clear of parapets and balustrades
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. 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.
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. 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.

Common questions
Is it secure?
Units lock from inside. As with any rooftop door, keep it locked when the house is empty.
Can it be opened from the roof?
Many units have an external handle or key for opening from outside. If you need that, tell us at survey.
Can it replace an old loft hatch?
Where there is a flat roof above, yes. On a pitched roof, an access roof window is the equivalent.
Will I need planning permission 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.
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.
