How we approach sun tunnels & tubular skylights in Balham
For Balham homes and buildings we offer sun tunnels & tubular skylights: light pipes that bring daylight to halls and bathrooms with no window. 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. Think of sun tunnels & tubular skylights for small internal rooms where a full rooflight will not fit.
Balham is around 7 km from central London, and we survey and fit throughout that part of Greater London, including the SW12 district.

- Ventilation adaptor

Before you order: points to check
- Tube runs need insulation in cold lofts to limit condensation
- Not a substitute for a habitable-room window
Planning, building control and 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.
Read the planning permission guide before you commit to a design.
