    Frequently Asked

    Secondary Glazing in Kensington — Your Questions Answered

    Do I need planning permission for secondary glazing in Kensington?+
    In most cases, no. Secondary glazing is installed internally behind your existing windows and is fully reversible, so it typically does not require planning permission or listed building consent — even for Kensington properties in conservation areas or Grade II listed buildings. Historic England actively recommends it as a sympathetic upgrade for heritage homes across W8, W14.
    How much noise reduction can I expect in Kensington?+
    Our standard secondary glazing systems reduce external noise by 50–70%. For Kensington homes exposed to heavier traffic or urban noise, our 10.8mm acoustic laminate specification delivers up to 80% perceived noise reduction (around 45–50dB), thanks to the wide 100–150mm air cavity between the original window and the new internal pane.
    Will secondary glazing suit a grand victorian mansions in Kensington?+
    Yes. Every unit is bespoke-manufactured to the exact dimensions of your existing window reveal, with slimline aluminium frames powder-coated in any RAL colour to match original joinery. This makes secondary glazing an ideal fit for grand victorian mansions, elegant garden square townhouses, prestigious mansion blocks and other typical Kensington property styles, preserving sightlines and heritage character.
    How much does secondary glazing cost in Kensington?+
    Standard configurations for Kensington homes start from around £350–£500 per window. Premium acoustic specifications with 10.8mm laminate glass, heritage detailing, or bespoke finishes typically range from £800–£1,200 per unit. Every quote is prepared after a free on-site survey, so pricing reflects your exact window sizes and specification.
    How long does installation take at a Kensington property?+
    After a free survey, manufacturing takes approximately 4–6 weeks. Installation itself is fast and clean — most Kensington rooms are completed within a single day, with dust sheets, full site protection, and all waste removed. Our team is used to working discreetly in occupied luxury homes across W8, W14.
