Dome rooflights in Kensington: what is involved?
For Kensington homes and buildings we offer dome rooflights: polycarbonate and acrylic domes for flat roofs, new or replacement. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Think of dome rooflights for schools, flats and commercial flat roofs.
Kensington sits about 2 km from Notting Hill and 2 km from Shepherds Bush, and we cover the whole W8 postcode district and the roads in between.
What you can choose
- Twin, triple or quad skin
- Fixed or hinged with vent
- Clear, opal or tinted
- Polycarbonate or acrylic
- Insulated PVC or GRP upstands
- Smoke-vent versions available
- Low cost per unit
What to check first
- Fire classification matters on some roofs
- Plastic domes have a lower acoustic and thermal performance than glass
Rules and responsibilities in Kensington
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.

Common questions
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Can domes open?
Hinged and vented domes are available, manual or electric.
