Existing validation checklists and definitions

Checklist for all types of applications and the definitions of each requirement.

The government has introduced a standardised set of national planning application forms, known as 1APP. All applications submitted since 6 April 2008 need to use the 1APP forms.

As part of 1APP, the government has defined national requirements for the information required to be submitted in support of a planning application. These national requirements are to be supplemented by mandatory local requirements, which will be decided on by individual Local Planning Authorities. The intention is to have one set of local requirements for all of Hillingdon.
