    Secondary Glazing in Streatham — Your Questions Answered

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

For Streatham 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.
