What is the purpose of a retrospective certificate of compliance in planning enforcement?

• A. To permit new development without notice
• B. To exempt the breach from penalties
• C. To suspend enforcement actions
• D. To certify compliance after a breach

Answer: (D)

The idea behind a retrospective certificate of compliance is post-event validation: it formally confirms that a breach of planning control now complies with the relevant permission or conditions attached to that permission. This is why it’s the best choice—the purpose is to certify that, after the works have occurred, they are in line with what was permitted, or have satisfied the planning requirements, so the development can be treated as compliant rather than as an ongoing breach.

This can help limit or avoid further enforcement because the breach is recognized as compliant with the planning regime. It does not, on its own, grant new development, suspend enforcement, or automatically exempt penalties without the proper assessment. It’s about retroactively affirming compliance after the event.
