Whether it's a single lantern over a Hampstead kitchen or a multi-roof development, our korniche 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 Hampstead — 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 Hampstead we also serve Greenwich, Ilford and Romford and the wider county — so if you're comparing quotes anywhere in Greater London, ours is free, fast and without obligation.
The frame itself can be assembled on the kerb in under 30 minutes by a competent installer; a full fit including glazing and flashing is comfortably a one-day job. Manufacture lead time is typically one to two weeks.
Yes — the system is fully thermally broken with no metal-to-metal path from outside to inside, and paired with argon-filled units it achieves U-values that comfortably satisfy Building Regulations for extensions.
Every Korniche is made to order, so 'custom' is the standard. You give us the external kerb size and the lantern arrives fabricated to those exact dimensions.
