If your home sits under a Heathrow flight path, you may be entitled to substantial funding toward acoustic glazing — potentially up to 100% of eligible insulation costs — through Heathrow's current noise insulation programme. The scheme is called the Quieter Neighbourhoods Support — Residential Insulation Scheme, and runs from 2025-2028 with around 20,000 homes eligible under phase one. Here's how it works in 2026, who delivers it, and where S&K Glazing fits in.
Who's eligible?
Eligibility is based on a composite noise boundary covering parts of TW (Hounslow, Twickenham, Feltham, Bedfont), UB (Hayes, Hillingdon, Harmondsworth, Sipson), SL (Slough, Datchet, Colnbrook) and KT (Kingston-area) postcodes nearest the airport. The exact boundary changes annually as flight patterns and aircraft mix evolve. The official portal is at heathrow.com — Local community — Noise — Quieter Neighbourhood Support.
What does the scheme cover?
The current scheme covers up to 100% of eligible insulation costs identified by Heathrow's independent acoustic surveyor — including replacement primary windows or secondary glazing, external doors, acoustically rated ventilation units in eligible rooms, loft insulation upgrades, and ceiling overboarding where required. Costs can exceed £20,000 per home depending on the property and the works specified. Homes that received earlier (pre-2024) basic measures are still eligible to apply.
Who installs the works?
Kier Places is Heathrow's appointed contractor for the 2025-2028 rollout. They handle the independent survey and installation directly through their approved network — Heathrow pays Kier directly, so the funded works are at no cost to eligible households. S&K Glazing is not part of Heathrow's appointed-installer network. We're an independent specialist offering eligibility checks, application guidance, and private acoustic installations for properties the scheme doesn't fund.
The application process
Step 1: register your interest with Heathrow via heathrow.com — phase one rolls out area-by-area through 2025-2028, so timing depends on your postcode. Step 2: Kier Places will contact you when your area opens. Step 3: a free independent acoustic survey of your property is arranged. Step 4: insulation works are installed by Kier's approved network and paid for directly by Heathrow.
Where private acoustic glazing fits in
The funded scheme covers a specific standard specification, and the boundary is finite. Three groups of Heathrow-area homeowners typically come to us privately: (1) properties just outside the noise contour boundary that still suffer aircraft noise; (2) eligible homeowners who want to upgrade beyond the scheme spec — premium acoustic triple glazing (Rw 48-52dB), thicker laminated acoustic interlayers, acoustic-rated trickle ventilation; (3) commercial premises and non-habitable rooms the scheme excludes.
Next steps
If you're inside the scheme boundary and want fully-funded works, the route is Heathrow's own portal — start at heathrow.com to register interest and wait for Kier Places to contact you. If you're outside the boundary, or you want better than the standard scheme specification, we can help. Call 0800 088 6341 for a free eligibility check and quote — we'll confirm whether your postcode is in the current Heathrow boundary, and explain what private acoustic options make sense for your property.
