There are a number of different types of application and it is important that you find the right type of application for your development. The council has produced a validation checklist for most of the application types. You should read this document carefully to ensure that you include all the information required in order to avoid delay in registering your application.
If your application has recently been determined that may not mean the end of the process. You may wish to appeal against a decision, apply for non-material minor amendments, apply for removal or variation of conditions.
