Permitted Development Rights
Permitted development rights under the GPDO means automatic planning permission rights granted for certain types of development, subject to conditions and limitations provided for in Article 3, Schedule 2 of the GPDO 1995. Permitted development rights operate by granting automatic planning permission to proposals that amount to development because it is a physical operation, or a material change of use, or both.
All information on permitted development can be found on the Planning Portal website. The Statutory Instrument for this can be found at: The Town and Country Planning (General Permitted Development) (Amendment) (England) Order 2015 .
In some areas, permitted development rights may have been removed or restricted. You should always check that a proposed scheme is permitted development before starting any works.
