Local and national requirements

Planning application requirements are specific requirements attached to certain types of planning applications. There are requirements at both a national and a local level.

The requirements you need to follow depend on the type of application being made.

National requirements

Full national requirements are set out in the Town and Country Planning Act (Development Management Procedure) (England) Order 2015 (DMPO) and the National Planning Policy Framework.
