Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Around Cheltenham and the wider county, housing stock runs to Cotswold-stone cottages and Regency terraces — slim heritage profiles and self-clean glass are frequent specs. We've specified and supplied for exactly these property types across Gloucestershire, so recommendations come from real local precedent.
Every lantern is thermally broken aluminium as standard, glazed with 28mm argon-filled units, and available with self-clean and solar-control coatings. Supply-only orders include kerb specifications and fitting documentation; installed projects carry our written workmanship guarantee on top of the 10-year product cover.
Cheltenham, Stow-on-the-Wold, Moreton-in-Marsh and Gloucester and the rest of Gloucestershire all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.
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.
