    W11 FAQs

    How much noise reduction can I expect in W11?

    Homes in Notting Hill typically see 35–42 dB reduction on voices & mid-frequency 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 Notting Hill?

    For the dominant noise here (Portobello & Notting Hill weekend noise), we recommend 8.8mm acoustic laminate 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 W11 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 Notting Hill flat is usually £3,200–£6,500 fully installed.
