Whether it's a single lantern over a Dulwich kitchen or a multi-roof development, our flat roof lanterns service pairs supply-only pricing with nationwide installation — and Greater London is core territory for both.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Greater London property here means Victorian terraces, side-return kitchen extensions and flat-roof rear additions where a roof lantern is the default way to pull daylight deep into the plan. That local context shapes what we recommend in Dulwich — from glass specification to frame colour — before a single quote is written.
Frames are thermally broken aluminium, glazing is 28mm argon-filled with self-clean and solar options, and everything is made to measure. Buy supply-only with kerbside delivery, or have our fitters handle the lot under a written workmanship guarantee.
From Dulwich we also serve Bromley, Ealing and Harrow and the wider county — so if you're comparing quotes anywhere in Greater London, ours is free, fast and without obligation.
Standard sizes below — made to measure quoted same day. Installation available nationwide if you’d rather we fit it.

A timber kerb at least 150mm above the finished roof surface, built to the lantern's external footprint. We issue exact dimensions at order so it's ready before the lantern arrives.
On installed projects, we coordinate it: the roofer dresses the membrane over the kerb, we bed and seal the lantern onto it. Supply-only orders include junction drawings for EPDM, GRP and felt so your roofer details it correctly.
Yes — we cut in, trim the joists, form the kerb and make good the membrane as part of an installed retrofit. A survey confirms joist direction and any services in the void first.
The lantern doesn't, but the junction detail differs: EPDM wraps the kerb, GRP laminates onto it, felt is torch-dressed. We supply the right drawing for each.
Yes — installation is available across Dulwich and Greater London, and if you'd rather buy supply-only, kerbside delivery to Dulwich is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Dulwich usually come back the same working day, and installed projects are priced after a free survey.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
