    Frequently Asked

    Secondary Glazing in Merton — Your Questions Answered

    Do I need planning permission for secondary glazing in Merton?+
    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 Merton properties in conservation areas or Grade II listed buildings.

    How much noise reduction can I expect in Merton?+
    Our standard secondary glazing systems reduce external noise by 50–70%. For Merton 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.

Every quote is prepared after a free on-site survey, so pricing reflects your exact window sizes and specification.
