Whether it's a single lantern over a Hornchurch 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
The Greater London market is defined by 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 — and our Hornchurch installs reflect that, with specifications matched to the property rather than pulled off a shelf.
Specification doesn't change with postcode: thermally broken frames, 28mm argon-filled glazing, marine-grade powder coating and a 10-year guarantee, whether you buy supply-only for your own builder or book our installation teams.
Our teams cover Hornchurch alongside Ealing, Harrow and Enfield and the rest of Greater London — surveys are free, quotes carry no obligation, and we aim for a response within 1 working hour.
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 Hornchurch and Greater London, and if you'd rather buy supply-only, kerbside delivery to Hornchurch is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Hornchurch 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.
