Whether it's a single lantern over a Grays kitchen or a multi-roof development, our korniche roof lanterns service pairs supply-only pricing with nationwide installation — and Essex is core territory for both.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
The Essex market is defined by 1930s semis, new-build estates and barn conversions — large bifold-plus-lantern rear extensions are the dominant project type — and our Grays 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 Grays alongside Basildon, Brentwood and Harlow and the rest of Essex — surveys are free, quotes carry no obligation, and we aim for a response within 1 working hour.
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.
Yes — supply-only Korniche orders are dispatched UK-wide with assembly instructions, and our team is on the phone if your builder has questions on the day.
The joint engineering. Korniche components machine together so precisely that the lantern assembles without silicone, external clips or cover caps — which is why installers love it and why the finished lines look so clean.
Yes — installation is available across Grays and Essex, and if you'd rather buy supply-only, kerbside delivery to Grays is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Grays 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.
