What do loft conversion skylights in Kensington involve?
Thinking about loft conversion skylights in Kensington? The short answer: roof windows planned for loft rooms — light, headroom and escape. The longer answer depends on your roof, which is why we survey before we 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. Loft conversion skylights suit loft conversions and rooms in the roof.

Planning, building control and 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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
How many roof windows does a loft room need?
Enough to give good light — a common rule of thumb is glazing equal to roughly a tenth to a fifth of the floor area, adjusted for orientation and use. We advise at survey.
Do loft roof windows need to be escape windows?
Some loft rooms need an escape window, depending on the layout and the fire strategy for the conversion. Building control confirms the requirement.
Can I add blinds later?
Yes — most manufacturers make blinds for each window size.
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.
