Applying for a lawful development certificate

You may want to apply for a lawful development certificate if you need reassurance that:

• what you want to do does not require planning permission (called 'permitted development')
• works done in the past were lawful

Lawful development certificates are not compulsory.

Before you apply, you should check to see if you need planning permission.

To complete your application you'll need:

• supporting plans and drawings in PDF, JPG or PNG format
• a credit or debit card to pay any planning fees

You can apply for a lawful development certificate using the Planning Portal.
