Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Like much of Warwickshire, Leamington Spa features Tudor market towns and commuter villages where orangery and lantern-roof extensions are a signature upgrade. It's the kind of work our surveyors and fitting teams handle week in, week out across the Midlands region.
You get the same product either way — thermally broken aluminium, self-clean and solar-control glass options, made to the millimetre. The only choice is who fits it: your builder with our documentation, or our own nationwide teams.
Coverage takes in Leamington Spa, Kenilworth, Alcester and Southam and every corner of Warwickshire. Surveys and quotes are free, with a response within 1 working hour on every enquiry.
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 Leamington Spa and Warwickshire, and if you'd rather buy supply-only, kerbside delivery to Leamington Spa is included in our standard service.
