What do sun tunnels & tubular skylights in Dulwich involve?
Sun tunnels & tubular skylights in Dulwich means light pipes that bring daylight to halls and bathrooms with no window. We cover the SE21 district and the rest of Greater London, with a survey before any price is fixed.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Typical uses for sun tunnels & tubular skylights include small internal rooms where a full rooflight will not fit.
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.

Do you need permission in Dulwich?
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. 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.
