The decision to grant planning permission from a retrospective planning application falls with your local planning authority.

Understand Your Options Before Taking the Next Step

Whether you have discovered that permission was needed or have already heard from the council, the right response depends on the development and any action taken so far.

What Is Retrospective Planning Permission?

A retrospective planning application seeks permission for development that has already taken place. The council considers the planning merits of the proposal; completing the work does not guarantee that permission will be granted.

Start by establishing what was built or changed, when it happened and what permissions already exist. Our planning consultants can assess whether a retrospective application is appropriate and identify the drawings and supporting evidence needed.

Received a Planning Enforcement Notice?

Seek advice promptly and send us the complete notice, accompanying plans and council correspondence. An investigation letter and a formal enforcement notice are different documents, so the first step is to establish exactly what you have received.

Check the effective date, required steps and compliance period. In England, an enforcement appeal must be received before the notice takes effect. Ask for advice on the appropriate response and any appeal rights before deciding whether to submit a retrospective application.

Retrospective Planning Application FAQs

How much does a retrospective planning application cost?

The cost depends on the size and scale of the development and the supporting documentation required. Contact our planning consultants to discuss your project. In England, the statutory planning application fee depends on the relevant development category; there is no single fee for every retrospective application.

What is the 10-year rule for retrospective planning permission?

The 10-year rule concerns time limits for planning enforcement, rather than an automatic grant of retrospective planning permission. In England, a 10-year period generally applies to building operations substantially completed, or a change of use to a single dwellinghouse made, on or after 25 April 2024. The previous four-year limits can still apply to those categories before that date; most other breaches have a 10-year period. Exceptions apply, including cases involving deliberate concealment or earlier enforcement action. The dates, evidence and location of the development need to be assessed.

What happens if retrospective planning permission is refused?

If your retrospective planning application is refused, then you may be subject to any Enforcement Action that the local planning authority has outlined to you. The local planning authority may require you to stop any further work or even revert the property to its original state or use. They can also require you to rebuild any demolitions.
