From Dulwich kitchen extensions to full orangery builds, our slimline roof lanterns service covers supply-only delivery and complete installation throughout Greater London — same product, your choice of who fits it.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Around Dulwich and the wider county, housing stock runs to Victorian terraces, side-return kitchen extensions and flat-roof rear additions where a roof lantern is the default way to pull daylight deep into the plan. We've specified and supplied for exactly these property types across Greater London, 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.
Dulwich, Hornchurch, Croydon and Bromley and the rest of Greater London all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.

Tighter tolerances, structural glazing and higher-spec profiles all add manufacturing cost, and installation needs more care. It's the premium tier of the lantern market and priced accordingly.

Yes — we'll send comparative section drawings showing our slimline profile against a standard lantern at the same scale, so the difference is concrete before you commit.
