How we approach commercial & industrial rooflights in Finchley
Thinking about commercial & industrial rooflights in Finchley? The short answer: rooflights for warehouses, schools, offices and retail units. The longer answer depends on your roof, which is why we survey before we price.
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. Commercial & industrial rooflights suit industrial roofs with tired or fragile rooflight sheets.
Finchley is around 11 km from central London, and we survey and fit throughout that part of Greater London, including the N3 district.

Building control and safety duties in Finchley
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. We confirm the route for your building before ordering.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.
