From flat-roof extensions to period slate roofs, we fit the right rooflight for the building in Highgate — after a survey, with a fixed written price.

Planning and building rules in England
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Skylight questions: Highgate
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.
Do I need to be at home for the survey in Highgate?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Highgate?
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.
Is the survey in Highgate free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Fixed or opening?
Opening units suit kitchens, bathrooms and bedrooms; fixed units are simpler and cheaper where the room already ventilates well.
Can I cancel?
Made-to-measure products are excluded from the statutory 14-day cancellation right, but you can cancel without charge until we place the order with the manufacturer. Our terms explain the rest.
