In Chelsea, Kensington, and Knightsbridge (SW3, SW7, SW10), secondary glazing is the preferred choice for residents of the Royal Borough. Our guides for these areas focus on 'Invisible Installations'—units that align perfectly with the existing meeting rails of sash windows. For properties near the V&A or Harrods, where traffic noise is a 24/7 issue, we recommend acoustic secondary glazing which can reduce decibel levels by up to 50dB, providing a sanctuary of calm in the heart of the city.
The Royal Borough's Glazing Challenges
Chelsea's elegant Georgian and early Victorian terraces along the King's Road, Cheyne Walk, and The Boltons demand an installation approach that is virtually undetectable. Many properties here are Grade II or Grade II* listed, requiring secondary glazing that leaves no permanent mark on original joinery. Our slim-profile aluminium frames, powder-coated to match existing timber, sit flush within the reveal and are completely reversible.
Kensington and Knightsbridge present a unique acoustic challenge. The constant flow of traffic along Brompton Road, Kensington High Street, and Knightsbridge itself creates persistent low-frequency noise that standard double glazing cannot adequately address. Our acoustic secondary glazing with 6.4mm laminated glass and a 100mm+ air cavity targets precisely these frequencies, delivering up to 50dB of noise reduction for homes overlooking the busiest thoroughfares.
Serving the Royal Borough of Kensington and Chelsea (RBKC), with particular focus on the Hans Town and Chelsea Conservation Areas. Ideal for the red-brick Queen Anne style houses where window preservation is a priority.

Preserving Period Windows in Chelsea & Kensington
The Royal Borough of Kensington and Chelsea is home to some of London's most tightly regulated conservation areas. Properties along the Boltons, Carlyle Square, and Onslow Gardens feature Victorian and Italianate sash windows that are integral to the borough's architectural character. RBKC's conservation officers require that any window treatment is completely invisible from the exterior. Our bespoke secondary glazing systems are designed precisely for this — recessed within the timber reveal, colour-matched to existing paintwork, and using slimline profiles that disappear behind original shutters and mullions. This approach means homeowners in SW3, SW7, and SW10 can eliminate road noise from the King's Road or Cromwell Road without compromising the heritage fabric that makes their homes so valuable.
Listed Buildings & Conservation
Do I need Listed Building Consent for secondary glazing?
Generally, secondary glazing is considered a reversible internal alteration and is widely supported by Historic England. However, in Grade I properties or sensitive areas like St James's, it is always best to check with the local conservation officer. Our guides help you choose 'Invisible' frames that are most likely to be approved.
