How we approach commercial & industrial rooflights in London
Our commercial & industrial rooflights service in London covers rooflights for warehouses, schools, offices and retail units. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
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 commercial & industrial rooflights include warehouses, schools, offices and retail units.
We cover all of London and the EC1A district, and nearby Pimlico and Islington.
Specification options
- Smoke and natural ventilation vents
- Modular glass rooflights
- Mesh or grilles under fragile areas
- Continuous barrel-vault rooflights
- GRP or polycarbonate in-plane rooflight sheets
- Smoke-vent options where needed
- Barrel vaults, ridge lights and modular glass
What to check first
- Fire performance of rooflight materials matters near boundaries
- Fragile rooflights are a known fall hazard — work at height must be planned
Regulations for commercial & industrial rooflights in London
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. Fire classification of rooflight materials near boundaries is checked at specification.
