Whether it's a single lantern over a Dulwich kitchen or a multi-roof development, our aluminium roof lanterns service pairs supply-only pricing with nationwide installation — and Greater London is core territory for both.
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 Dulwich 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 Dulwich alongside Croydon, Bromley and Ealing and the rest of Greater London — surveys are free, quotes carry no obligation, and we aim for 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. Our powder coat is marine-grade as standard, and aluminium itself doesn't rust. For exposed shoreline plots we can also upgrade fixings and glazing to suit the wind loading.
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.
Strength. Aluminium carries the same glass on much slimmer bars, so the lantern looks lighter and lets more daylight through. It also holds its colour and shape for decades, where uPVC profiles are bulkier and can discolour.
Not when thermally broken. The polyamide barrier separates the cold external aluminium from the warm internal face, keeping the inside surface above dew point in normal conditions. Good room ventilation does the rest.
Yes — installation is available across Dulwich and Greater London, and if you'd rather buy supply-only, kerbside delivery to Dulwich is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Dulwich usually come back the same working day, and installed projects are priced after a free survey.
