Local information requirements: Town centre use sequential assessments and impact assessments

Types of application that require this information

Sequential assessment

A sequential assessment is required for planning applications for all main town centre uses (new build, extensions and changes of use) which are neither in an existing centre nor in accordance with an up to date plan.

Impact assessment

An impact assessment is required for planning applications for retail and leisure development over 2500m2 of gross floorspace outside town centres which are not in accordance with an up to date plan.

Details of what should be included

Sequential assessment:

• Should be proportionate and appropriate for the proposed development
• Identification and details of the catchment area for the proposed development
• Consideration of sequentially preferable sites/premises within the catchment area having regard to the suitability, viability and availability
• Scope for flexibility in the format and scale of the proposed development

Impact assessment:

• Identification of scope of assessment
• Impact of all town centres that may be affected - which are not necessarily just those closest to the proposal and may be in neighbouring authority areas
• Impact should be assessed on a like-for-like basis in respect of that particular sector

Please refer to the GOV.UK website on ensuring the viability of town centres.

Applicants are advised to seek pre-application advice from the local planning authority in order to agree the scope, key impacts for assessment, and level of detail required in advance of applications being submitted.
