From Dartford kitchen extensions to full orangery builds, our aluminium roof lanterns service covers supply-only delivery and complete installation throughout Kent — same product, your choice of who fits it.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Around Dartford and the wider county, housing stock runs to weatherboard cottages, Victorian villas and a huge commuter-belt extension market — kitchen-diner lanterns are the signature project here. We've specified and supplied for exactly these property types across Kent, 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.
Dartford, Sevenoaks, Whitstable and Herne Bay and the rest of Kent 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.

Far bigger than most rooms need — spans over 3m wide and 6m long are achievable with reinforced ridge sections. Past a certain size we'd recommend twin lanterns instead, purely for proportion.
Yes — installation is available across Dartford and Kent, and if you'd rather buy supply-only, kerbside delivery to Dartford is included in our standard service.
