Section 100ZA of the Town and Country Planning Act 1990 (the 1990 Act), which was inserted by section 14 of the Neighbourhood Planning Act 2017, provides that planning permission for the development of land may not be granted subject to a pre-commencement condition (as defined in section 100ZA(8) of the 1990 Act) without the written agreement of the applicant to the terms of the condition. This requirement is subject to such exclusions as may be prescribed by the Secretary of State (see section 100ZA(6)).
