Local planning authorities must publish information at least annually that shows progress with Local Plan preparation, reports any activity relating to the duty to cooperate and shows how the implementation of policies in the Local Plan is progressing and are encouraged to report as frequently as possible on planning matters to communities.
This is important to enable communities and interested parties to be aware of progress. Local planning authorities can also use the Authority Monitoring Report to provide up-to-date information on the implementation of any neighbourhood plans that have been brought into force, and to determine whether there is a need to undertake a partial of full review of the Local Plan.
The National Planning Policy Framework requires local planning authorities to identify and update annually a supply of specific deliverable sites sufficient to provide 5 years’ worth of housing.
Once published, such assessments should normally not need to be updated for a full 12 months unless significant new evidence comes to light, or the local authority wishes to update its assessment earlier.
