The purpose of this Historic England Good Practice Advice note is to provide information to assist local authorities, planning and other consultants, owners, applicants and other interested parties in implementing historic environment policy in the National Planning Policy Framework (NPPF) and the related guidance given in the National Planning Practice Guide (PPG).

While it supports the implementation of national policy it does not constitute a statement of Government policy itself, nor does it seek to prescribe a single methodology or particular data sources. Alternative approaches may be equally acceptable, provided they are demonstrably compliant with legislation, national policies and objectives.
