Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Around Finchley 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.
Finchley, Chiswick, Dulwich and Hampstead and the rest of Greater London all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.
Only on certain systems — vents are normally factory-built into the roof slope. Send photos of your lantern and we'll confirm whether a retrofit sash exists for it or whether replacement is the honest answer.
Your choice: a simple wall switch, a remote, app control, or full automation that opens on temperature and closes on rain. Most kitchens land on switch-plus-rain-sensor.
Not in a quality system — the sash closes onto continuous gaskets and locks down tight. The vent panes carry the same glazing spec and guarantee as the fixed glass around them.
Over kitchens and in south-facing rooms, emphatically yes — venting at the highest point purges heat and steam faster than any window can. In cooler, well-ventilated rooms a fixed lantern plus good doors often suffices.
Yes — installation is available across Finchley and Greater London, and if you'd rather buy supply-only, kerbside delivery to Finchley is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Finchley usually come back the same working day, and installed projects are priced after a free survey.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
