How do I find out if a neighbour has complained about my application?

All correspondence relating to an application should be copied to the applicant (or their agent) by the responding local planning authority.

If you want to view the comments made on an application by neighbours you can do so by contacting your local planning authority or visiting in person.

You can find contact details for your local planning authority on the Planning Portal¹.
