W8 FAQs
How much noise reduction can I expect in W8?
Homes in Kensington typically see 38–45 dB reduction on low-frequency road noise, depending on window size, façade condition and glass specification. We measure before and after with a calibrated sound-level meter as part of every install.
What glass specification is best for Kensington?
For the dominant noise here (Kensington High Street traffic), we recommend 10.8mm acoustic laminated glass with 150mm cavity. In listed buildings or conservation areas we use the same acoustic performance in a discreet slimline frame that satisfies planners.
Do I need planning permission in Kensington & Chelsea?
Secondary glazing is internal work and is almost never controlled by planning permission — even in conservation areas. Grade II listed buildings need Listed Building Consent, which we handle with drawings and a heritage statement as part of the quote.
How much does a typical W8 install cost?
London prices in 2026 start at £450 per window for a small sash and rise to £1,600 for large Georgian sashes with premium acoustic glass. A three-bed Kensington flat is usually £3,200–£6,500 fully installed.
