Do I need planning permission?
Generally, any development will require planning permission. Under planning law "development" is defined as: "the carrying out of building, engineering, mining or other operations in, on, over or under land, or the making of any material change in the use of any buildings or other land".
Some extension works to a property may not require permission due to permitted development rights. For further information visit the permitted development rights page of the Planning Portal website.
If you are unsure whether your proposal constitutes development or whether it is permitted development, you can apply for a Lawful Development Certificate and we will then advise as to whether or not planning permission is required.
You can also make an enquiry at our customer service centres.
Please contact us before you start any works. Unauthorised development could lead to enforcement action.
Interactive guides on the Do I need planning permission page of the Planning Portal help you explore how to progress common householder development projects.
Under the Planning Acts, there are over 15 different types of application. If you are unsure which application you need to submit please contact planning services for advice.
