[Topic/Question] When does the formal pre-application stage start? [Answer] 
Advice Note 8.1 explains that the process begins when the Planning Inspectorate is informed by a developer that they intend to submit an application in the future. The project is then added to the Programme of Projects along with the expected date of submission. Formally the pre-application stage starts when the developer notifies the Planning Inspectorate under section 46 of the Planning Act 2008 before starting their consultation under section 42.
