    Frequently Asked

    Secondary Glazing in Marylebone — Your Questions Answered

    Do I need planning permission for secondary glazing in Marylebone?+
    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 Marylebone properties in conservation areas or Grade II listed buildings. Historic England actively recommends it as a sympathetic upgrade for heritage homes across W1U, W1G, W1H.
    How much noise reduction can I expect in Marylebone?+
    Our standard secondary glazing systems reduce external noise by 50–70%. For Marylebone 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 elegant georgian townhouses on garden squares in Marylebone?+
    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 elegant georgian townhouses on garden squares, distinguished mansion block apartments, period properties on marylebone high street and other typical Marylebone property styles, preserving sightlines and heritage character.
    How much does secondary glazing cost in Marylebone?+
    Standard configurations for Marylebone 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 Marylebone property?+
    After a free survey, manufacturing takes approximately 4–6 weeks. Installation itself is fast and clean — most Marylebone rooms are completed within a single day, with dust sheets, full site protection, and all waste removed.
