Heritage Performance Guide
London properties present unique challenges for secondary glazing. From the strict requirements of Kensington & Chelsea's conservation officers to the delicate frames of Hampstead's Georgian sashes, one size never fits all.
In these high-value areas, we don't just 'install windows'; we engineer acoustic barriers that preserve history. In Central London, noise levels from arterial roads like the A40 or the flight paths over Richmond often exceed 75dB. Our specialised 6.8mm Acoustic Laminate is designed to drop these levels by up to 54dB, while our slimline frames remain virtually invisible from the street, satisfying both aesthetic and regulatory demands.

Why London Pricing Is Different
Listed Building Complexity
- • Conservation officer pre-approval required in RBKC, Westminster, and Camden
- • Grade I & II* listings demand reversible, zero-damage installations
- • Slimline aluminium profiles matched to existing joinery profiles
- • Specialist survey required for properties on Grosvenor & Cadogan Estates
London Market Factors
- • London labour costs 20–35% higher than national average
- • Congestion Zone surcharges apply to Central London deliveries
- • Premium glass specs (6.8mm–10.8mm acoustic) standard in noise hotspots
- • Parking permits and access logistics factored into quotes
