The following information has been provided by the Planning Inspectorate (PINS) about the time limit for submitting an appeal where prior approval is refused under Part 1 Class A of the GPDO:
"Following amendment to the Town and Country Planning (General Permitted Development) Order 1995 as introduced in The Town and Country Planning (General Permitted Development)(Amendment) (England) Order 2013 (SI 2013 No, 1101), the Planning Inspectorate has received a number of calls from Local Planning Authorities seeking confirmation of associated appeals procedures in the event of refusal of approval.
Applications which require action in accordance with paragraph A.4 of Part 1 of Schedule 2, Class A of the General Permitted Development Order (as amended), are considered to fall within the description (b) of 'householder application' as detailed at Article 2 of the Town and Country Planning (Development Management Procedure)(England) Order 2010 and Regulation 2 of the Town and Country Planning (Appeals)(Written Representations Procedure)(England) Regulations 2009.
Appeals following refusal of approval will therefore be subject to the normal procedures for Householder Appeals as detailed within SI 2009 No. 452, with the time limit for submission being 12 weeks from the date of the notice of the decision or determination giving rise to the appeal, as detailed in Article 33 of the DMPO.
It is understood that a 'neighbours' consultation scheme notification form' will be made available on the Planning Portal in due course."
