Certificate of lawful development
You can apply for a certificate when you wish to clarify that an existing or proposed use or development is lawful under the relevant planning acts.
Householders often use this certificate to clarify that proposed alterations and extensions fall within permitted development rights, and/or are immune from enforcement action because the work took place more than 4 years ago.
The quickest and easiest way to submit a planning application is online via the Planning Portal.
