Whether it's a single lantern over a Hatfield kitchen or a multi-roof development, our korniche roof lanterns service pairs supply-only pricing with nationwide installation — and Hertfordshire is core territory for both.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Hertfordshire property here means garden-city housing, 1930s semis and a fast-moving extension market across the commuter towns. That local context shapes what we recommend in Hatfield — 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 Hatfield we also serve Hemel Hempstead, Stevenage and Welwyn Garden City and the wider county — so if you're comparing quotes anywhere in Hertfordshire, ours is free, fast and without obligation.
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 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.
Yes — installation is available across Hatfield and Hertfordshire, and if you'd rather buy supply-only, kerbside delivery to Hatfield is included in our standard service.
