Secondary Glazing for London Flats & Apartments
The noise and heat solution that doesn't need freeholder permission in most cases.
Why Secondary Glazing is Ideal for Flats
More Londoners live in flats than houses. For many, secondary glazing is the only option for improving windows — leasehold restrictions, listed building status, and conservation areas often prohibit window replacement.

Common Flat Challenges — Solved
Leasehold Note
Secondary glazing is classified as an internal alteration and does not affect the exterior of the building. In most cases, no freeholder or landlord consent is required. Always check your specific lease terms — we can provide documentation showing that secondary glazing is non-structural and fully reversible.
