We've made bespoke roof lanterns straightforward for Clapham: order supply-only with delivery to your door, or book our fitting teams and have the whole project — survey to seal — handled for you.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
The Greater London market is defined by 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 — and our Clapham installs reflect that, with specifications matched to the property rather than pulled off a shelf.
Specification doesn't change with postcode: thermally broken frames, 28mm argon-filled glazing, marine-grade powder coating and a 10-year guarantee, whether you buy supply-only for your own builder or book our installation teams.
Our teams cover Clapham alongside Barnet, Wandsworth and Walthamstow and the rest of Greater London — surveys are free, quotes carry no obligation, and we aim for a response within 1 working hour.
Anything outside a standard rectangular, centre-ridge design — unequal hips, off-centre ridges, three-sided lanterns against walls, linked twin lanterns, unusual pitches or glass specifications. If your drawing doesn't look like a catalogue picture, it's bespoke.
Yes — that's the normal route. Send the roof plan and sections; we return engineered lantern drawings for approval, flag any buildability issues early and fabricate only once everything is signed off.
It depends entirely on what departs from standard. An off-centre ridge adds little; a 7-metre triple-hip lantern with acoustic glass is a different conversation. We price from drawings with no obligation.
Allow 4–8 weeks from approved drawings, longer for unusual glass. We'll commit to a fabrication slot when you approve, so the lantern lands when your build needs it.
Yes — Clapham is inside our standard Greater London coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to Clapham on dedicated glass transport.
Stocked standard sizes typically deliver to Clapham within 7–10 working days; made-to-measure fabrication adds to that, and we confirm the slot when you order so it lands with your build programme.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
