Dome rooflights in Greenford: what is involved?
Thinking about dome rooflights in Greenford? The short answer: polycarbonate and acrylic domes for flat roofs, new or replacement. The longer answer depends on your roof, which is why we survey before we 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. Think of dome rooflights for schools, flats and commercial flat roofs.
Greenford sits about 2 km from Northolt and 2 km from Southall, and we cover the whole UB6 postcode district and the roads in between.

Building control and safety duties in Greenford
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Can domes open?
