Dome rooflights for Chelsea: the essentials
We handle dome rooflights across Greater London, including Chelsea. In short: polycarbonate and acrylic domes for flat roofs, new or replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
Jobs in Chelsea are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Clear, opal or tinted
- Polycarbonate or acrylic
- Insulated PVC or GRP upstands
- Fall-through protection mesh
- Twin, triple or quad skin
- Low cost per unit
- Light, impact-resistant domes
Things we check at survey
- Plastic domes have a lower acoustic and thermal performance than glass
- Old domes may be fragile — treat as fragile until checked
Regulations for dome rooflights in Chelsea
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. 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.

Dome rooflights in Chelsea: questions
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Should I replace a dome or switch to glass?
A dome is cheaper and quick; glass gives a clear view and better performance. On a tight budget, or a commercial roof with many units, domes remain sensible.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
How do I book a survey in Chelsea?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Chelsea?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
