How we approach loft conversion skylights in Hampstead
We handle loft conversion skylights across Greater London, including Hampstead. In short: roof windows planned for loft rooms — light, headroom and escape. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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. Typical uses for loft conversion skylights include loft conversions and rooms in the roof.
We work across Greater London, including Hampstead, and in neighbouring towns such as Kilburn and Highgate. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Hampstead
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. 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. 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.

Loft conversion skylights in Hampstead: questions
Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
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.
Top-hung or centre-pivot in a loft?
Top-hung gives a clearer view and often suits escape use; centre-pivot is easier to clean and suits higher positions.
Will I need planning permission in Hampstead?
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.
How do I book a survey in Hampstead?
