The statutory determination period for validatedย planning applications, which localย planningย authoritiesย shouldย not exceed, is 8 weeks for straight-forwardย planning applications, 13 weeks for unusually large or complexย applications, and 16 weeks if theย applicationย is subject to an Environmental Impact Assessment (EIA).
Failure to determine the application within these deadlines means that the applicant can choose to appeal to the Planning Inspectorate on the grounds of non-determination. ย Local planning authorities have to inform applicants of these rights.
See “Determining a planning application” on the government website which sets out the process and expectations on planning performance and decision making.
