Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Around Portishead and the wider county, housing stock runs to stone farmhouses, Georgian crescents and village homes with steady orangery and kitchen-extension demand. We've specified and supplied for exactly these property types across Somerset, 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.
Portishead, Weston-super-Mare, Frome and Glastonbury and the rest of Somerset all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.
Standard sizes below — made to measure quoted same day. Installation available nationwide if you’d rather we fit it.

Yes — installation is available across Portishead and Somerset, and if you'd rather buy supply-only, kerbside delivery to Portishead is included in our standard service.
