Secondary glazing for Norwich’s listed and conservation homes
With one of the highest concentrations of listed buildings in England outside London, Norwich is exactly where secondary glazing earns its keep. It fits inside the original window reveal, keeps the historic frontage untouched, and rarely needs Listed Building Consent — a rare combination in the city-centre conservation area.
Why locals in Norwich choose Legacy Windows
- Typical quotes fall between £320 and £860 per window, depending on frame system and glass thickness.
- Installers specify slimline aluminium or timber-look frames that sit discreetly behind the original sash or casement.
- Acoustic glass options cut street noise by up to 45 dB, useful on Bethel Street or near Prince of Wales Road.
- Removable panels allow the original window to open in summer without dismantling.
- No structural work and no changes to the external elevation — usually consent-free even on Grade II listed homes.

Frequently asked questions
Does secondary glazing need Listed Building Consent in Norwich? Usually no, because it is a reversible internal alteration that does not affect the original fabric. That said, Norwich City Council conservation officers can require consent on Grade I or Grade II* buildings, so a quick check before ordering is worthwhile.
How much does secondary glazing improve heat loss? A well-fitted secondary panel typically halves U-value on a single-glazed sash, taking it from around 5.4 to 2.5 W/m²K. It also cuts draughts, which often matters more day-to-day than the U-value figure alone.
Will it stop condensation on my sash windows? Secondary glazing usually shifts condensation onto the outer pane rather than eliminating it, because the room-side air is now separated from the cold surface. Trickle ventilation on the outer window helps keep the cavity dry.
