Lawful development certificate

For peace of mind that an existing or proposed use of a building is lawful or that the proposal doesn’t require planning permission, you can apply for a lawful development certificate (LDC).

This is a legal document stating the lawfulness of past, present or future building use. If granted, it means that enforcement action cannot be carried out to the development referred to in the certificate.

However, the certificate will not protect from enforcement action if the specified use is then changed 'materially' without a planning application for it.

Examples of when an application for an LDC should be made include:

  • when planning enforcement action is taken and the owner believes it is immune from action because the time limit for taking enforcement action has passed.
  • when an owner discovers, in the course of a sale of the land, that planning permission has never been granted, and needs to show a prospective purchaser that no enforcement action can be taken by the local planning authority.

Before you apply, please read the guidance on GOV.UK or refer to the Planning Portal.

How to apply

You can 

A fee will be payable - please refer to our planning fees and how to pay.

We will notify you of our decision within 8 weeks (6 weeks for a listed building).

Appeal a decision about a lawful development certificate

You can appeal to the Planning Inspectorate if:

  • you disagree with our decision
  • the decision wasn’t made within 8 weeks (6 weeks for work to a listed building)
Don’t appeal if you’ve already been given an enforcement notice. 

The Planning Inspectorate will not be considering the planning merits of your proposal, just whether the evidence that you have provided is sufficient to prove the lawfulness of the development or not.
