Grey Belt – Wrotham Parish Council v SSHCLG (High Court)

On the 30 January 2026 the judgement for the case of Wrotham Parish Council was handed down. This case provided a High Court ruling on how the government’s Grey Belt planning policy should be interpreted.

What is 'the grey belt'?

Grey Belt was introduced in the December 2024 NPPF and is defined as land in the Green Belt comprising previously developed land and/or any other land that, in either case, does not strongly contribute to any of the Green Belt purposes (a), (b), or (d) in paragraph 143 of the NPPF to check the unrestricted sprawl of large built up areas, prevent neighbouring towns merging into one another and to preserve the setting and special character of historic towns respectively.

Grey Belt excludes land where the application of the policies relating to the areas or assets in footnote 7 (other than Green Belt) would provide a strong reason for refusing or restricting development.

Footnote 7 attaches to paragraph 11 of the NPPF and defines the specific policies for protected areas and assets that restrict the presumption in favour of sustainable development (the "tilted balance"). It lists areas of particular importance where development may be restricted, including habitats sites, Sites of Special Scientific Interest, Green Belt, Local Green Space, National Landscapes, National Parks, heritage assets, and flood risk areas etc. 

Case background

• In March 2023, Moto Hospitality Ltd applied for outline planning permission for the “construction of a secure 24-hour truck stop facility for up to 197 HGVs incorporating fuel station; amenity building of up to 1100 sqm; creation of a new access to A20 via roundabout; landscaping and other associated works”.

• Tonbridge and Malling Borough Council refused the application in February 2024 citing reasons relating to (1) inappropriate development in the Green Belt and (2) impact on the character and appearance of the area, and harm to the Kent Downs National Landscape through the introduction of built form and lighting.

• Moto appealed the refusal and the appeal was allowed by the Inspector on the 13 February 2025. In granting permission, the inspector had decided that the site constituted Grey Belt land and concluded that the Footnote 7 national landscape policies did not provide a strong reason for refusing the development. 

• The Parish Council challenged the Inspector’s decision to the High Court.

• Ground 1 of that challenge was that the Inspector misinterpreted the definition of Grey Belt by treating it as requiring consideration of whether footnote 7 policies provided a strong reason for refusing or restricting “the” specific development, and not development “generally” on the Site.

• To put it another way, the NPPF’s glossary says that grey belt “excludes land where the application of the policies relating to the areas or assets in footnote seven (other than green belt) would provide a strong reason for refusing or restricting development”. The Parish Council essentially argued that, if the Inspector was correct, this should read “restricting the development”. 

Judgement

The Court rejected the Parish Council’s argument that the definition required consideration of whether Footnote 7 policies would provide a strong reason for refusing development generally on the site.

The Court commented that “the claimant takes a highly linguistic analysis, which essentially turns on the fact that the word ‘the’ is not included at the end of the grey belt definition” but a “strong reason for refusing… development” would “naturally be expected to depend on what development was being applied for, rather than making a hypothetical assessment of the impact of any or all developments that could possibly come forward”.

Effectively, the Court confirmed that decision-makers should consider whether the particular project conflicts with key protective policies, not whether the land should be shielded from all possible development.

The Court also found the Inspector's interpretation aligned with the policy purpose of introducing Grey Belt to allow release of Green Belt land where it did not strongly contribute to green belt purposes and where there was no strong reason for refusal under footnote 7 policies - Grey Belt policy should not be interpreted too narrowly.

Key takeaways

This case confirms that when considering Footnote 7 of the NPPF, one should consider whether the particular project conflicts with key protective policies, not whether the land should be shielded from all possible development.

However, the long-term significance of the ruling may be limited because the Government launched a consultation in December 2025 on revising the NPPF in which it proposed dropping Footnote 7 protected land exclusions from the Framework’s Grey Belt definition all together. And if enacted, the ruling would then become academic only or at least only relevant to decisions made under the current version of the NPPF.
