Our bespoke solutions respect the borough's rich architectural heritage while providing outstanding thermal and acoustic performance.

    Frequently Asked

    Secondary Glazing in Islington — Your Questions Answered

    Do I need planning permission for secondary glazing in Islington?+
    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 Islington properties in conservation areas or Grade II listed buildings. Historic England actively recommends it as a sympathetic upgrade for heritage homes across N1, N5, N7.
    How much noise reduction can I expect in Islington?+
    Our standard secondary glazing systems reduce external noise by 50–70%. For Islington 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 pristine georgian townhouses in barnsbury and canonbury in Islington?+
    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 pristine georgian townhouses in barnsbury and canonbury, elegant victorian terraces with ornate original features, industrial loft conversions with contemporary glazing and other typical Islington property styles, preserving sightlines and heritage character.
    How much does secondary glazing cost in Islington?+
    Standard configurations for Islington 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 Islington property?+
    After a free survey, manufacturing takes approximately 4–6 weeks. Installation itself is fast and clean — most Islington 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 N1, N5, N7.
