NPPF Paragraph 200 , Full Text and Practical Application
Paragraph 200 of the December 2024 NPPF places an applicant duty: 'In determining applications, local planning authorities should require an applicant to describe the significance of any heritage assets affected, including any contribution made by their setting. The level of detail should be proportionate to the assets' importance and no more than is sufficient to understand the potential impact of the proposal on their significance.' This is the source of the significance-and-proportionality test that governs every UK HIA.
Three sub-tests inside paragraph 200
- Significance test. Describe what makes the asset important.
- Setting test. Include any contribution made by setting.
- Proportionality test. Detail commensurate with importance , no more, no less.
How consultants demonstrate compliance
Structure the HIA around the GPA 2 sequence: significance assessment first, setting analysis (per GPA 3) second, impact evaluation third, mitigation fourth. Cite the listing description verbatim, then go beyond it. The LPA officer's first compliance check is whether all of significance, setting and proposal are addressed in the same document.
The 'proportionate' trap
The most common reason an LPA returns an HIA is 'disproportionate' , typically too short for the importance of the asset. A four-paragraph statement for a Grade I scheduled monument is not proportionate; nor is a 25-page report for a single internal alteration to a Grade II house. Match length and depth to the asset.
Cases that have tested paragraph 200
Bedford BC v SoSCLG [2013] EWHC 2847 (Admin) is the leading case on the substantial-harm threshold. Forge Field Society [2014] EWCA Civ 137 confirms the special-regard duty operates on top of the paragraph 200 test. Pugh v SoSCLG [2015] EWHC 3 (Admin) confirms that the proportionality test is for the LPA, not the applicant, to apply on the merits.
