If you disagree with a planning decision made on your planning application, you can appeal against our decision. You can’t make an appeal against a decision made on someone else’s planning application.
Find out about making an appeal against a planning decision at GOV.UK.
You can appeal if your application is:
not decided within a set period
refused by the local authority
granted on conditions you disagree with
There’s a different process to appeal a householder planning decision for a smaller project like an extension, conservatory or loft conversion.
