Inhabitants of any land or building within Great Britain will need both a land or building title of ownership and also a planning title or planning permission. Planning permission, or planning consent, is the necessary permission in Great Britain needed to build on land or change the function of land or buildings. The Town and County Planning Act 1947 allow all pre-existing uses and buildings. Development is only confined to building, engineering, mining operation or the change of function of any land or building. Thus, planning permission applications exempt certain types of operation, such as the routine maintenance of an existing building. The local planning authorities (LPAs) administer and enforce rules and policies in the planning permission application.
It is required by law that the policies of a development plan are the basis for deciding with planning permissions, making it evident that the planning application is rather policy-led than influence-led. It is essential that planning permission applicants comply with relevant local development plans before pursuing an application. There are different types of applications when planning permission, including full planning permission, outline planning permission, approval of reserved matters and removal or alteration.
Planning permissions are customarily subject to planning conditions after being granted. Planning conditions may include the start date of development, the building design in reference to the drawings and any other conditions related to the implementation of works within the actual site.
