Approved applications in your area are public. Looking at what has actually been permitted nearby — not what has merely been installed — tells you a great deal about how your authority treats window replacement locally, and a specific approved case is a far stronger reference point than a neighbour's windows.

• Respect the original proportions and glazing pattern, which is usually what an officer looks at first.
• Choose a profile designed for heritage contexts rather than a standard modern one.
• Consider treating the principal elevation sympathetically and being more contemporary at the rear.
• Use a pre-application enquiry to establish the authority's view before spending money on a specification.
• Document what is currently installed — particularly if it is already an unsympathetic modern replacement.
