Secondary glazing for AL9 homes
In 1930s bays, secondary glazing can follow each facet of the bay or span across it, so we measure carefully around radiators, sills and curtain tracks.
Older cottages with small leaded or timber windows can keep their character with discreet secondary panels, hinged or removable so the originals stay accessible for maintenance.
Secondary glazing is a discreet second window fitted on the inside of your existing windows, leaving the originals untouched. It suits listed buildings, conservation areas, flats where external windows cannot be changed, and anyone wanting to cut noise and draughts without replacing period windows.
- Keeps original windows in place
- Reduces draughts and outside noise
- Suitable where replacement is restricted
Questions from AL9
Do I need planning permission for secondary glazing in AL9?
Secondary glazing is fitted internally, so it does not usually need planning permission or Building Regulations approval, but listed buildings may need listed building consent first.
How soon can you fit secondary glazing in AL9?
Lead times vary by product and workload — confirmed with your quote. Being about 11 miles from our factory makes surveys, fitting days and aftercare visits easy to arrange.
Is secondary glazing allowed in listed buildings in AL9?
Secondary glazing is generally seen as less intrusive than replacing original windows, because it sits inside and is reversible. However, listed building consent may still be required, so speak to the council's conservation officer before work starts. We can provide product details to support your application.

Yes. Our showroom is at Unit G, 1 Anthony Way, London N18 3QT (Mon–Fri 8am–5pm), about 11 miles from AL9. We can also bring samples to your home in AL9 at the free survey.
