A Certificate of Lawfulness (often called a Lawful Development Certificate) is a formal council document confirming that a specific piece of development — an existing extension, or a proposed one — is lawful, either because it qualified as permitted development or because it has existed unchallenged for a long enough period (commonly four or ten years, depending on circumstances) that enforcement action is no longer possible.
For a proposed extension, applying for this certificate before building confirms your permitted development position formally and in writing, rather than relying on your own (or your builder's) interpretation of the rules.
For an existing, older extension without clear paperwork, obtaining a certificate retrospectively resolves any ambiguity before you sell the property — this is one of the most common gaps we see flagged by a buyer's solicitor during a house sale, and it's far easier to resolve before marketing the property than during a live transaction.
