How we approach loft conversion skylights in Highgate
For Highgate homes and buildings we offer loft conversion skylights: roof windows planned for loft rooms — light, headroom and escape. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Loft conversion skylights suit loft conversions and rooms in the roof.
Neighbouring towns include Hampstead (2 km) and Kilburn (3 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Highgate
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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 loft conversion skylights in Highgate
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 you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
How do I book a survey in Highgate?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Highgate?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
