Frequently asked questions
Do I need Listed Building Consent for sash windows in Norwich? If your property is listed, yes — any window change requires consent from Norwich City Council, even a like-for-like timber replacement. The historic core also has an Article 4 direction restricting permitted development, so a planning check is worthwhile even on unlisted properties.
Can I fit double glazing in a Georgian box sash? Slim double-glazed units can be retrofitted into most existing sashes if the sash box has enough depth. In conservation areas, planners typically insist on units under 14mm overall with matching glazing bar detail. Secondary glazing is often preferred on listed frontages.
How much does draught-proofing cost versus full replacement? Draught-proofing a working sash usually costs £250 to £450 per window and can cut infiltration by 60 to 80 percent. A full replacement in painted softwood normally starts around £900. Many Norwich owners phase the work over several years.
