What does skylight installation in Balham involve?
We handle skylight installation across Greater London, including Balham. In short: survey, supply and fit — new openings, extensions and fit-only work. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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. Typical uses for skylight installation include new extensions, new openings and fit-only jobs.
We work across Greater London, including Balham, and in neighbouring towns such as Clapham and Streatham. Access, parking and how the glass reaches the roof are all checked at the survey.

Consents for skylight installation in Balham
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. 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.

Skylight installation in Balham: questions
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
Do you fit rooflights bought elsewhere?
Yes. We check the product and the opening first, and our workmanship terms cover the fitting rather than the product.
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
Is the survey in Balham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
