Skylights and rooflights in Dulwich
From flat-roof extensions to period slate roofs, we fit the right rooflight for the building in Dulwich — after a survey, with a fixed written price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope.
We work across Greater London, including Dulwich, and in neighbouring towns such as Brixton and Peckham. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules in England
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. 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.
