EC2 FAQs
How much noise reduction can I expect in EC2?
Homes in City / Liverpool St typically see 42–48 dB reduction across mainline rail spectrum, depending on window size, façade condition and glass specification. We measure before and after with a calibrated sound-level meter as part of every install.
What glass specification is best for City / Liverpool St?
For the dominant noise here (Liverpool Street mainline noise), we recommend 12.8mm asymmetric acoustic laminate with 200mm cavity. In listed buildings or conservation areas we use the same acoustic performance in a discreet slimline frame that satisfies planners.
Do I need planning permission in City of London?
Secondary glazing is internal work and is almost never controlled by planning permission — even in conservation areas. Grade II listed buildings need Listed Building Consent, which we handle with drawings and a heritage statement as part of the quote.
How much does a typical EC2 install cost?
London prices in 2026 start at £450 per window for a small sash and rise to £1,600 for large Georgian sashes with premium acoustic glass. A three-bed City / Liverpool St flat is usually £3,200–£6,500 fully installed.
