Wrotham Parish Council v Secretary of State for Housing, Communities and Local Government & Ors [2026] EWHC 165 (Admin)
Wrotham grey belt is one of the first High Court judgments to interpret the grey belt definition introduced into the NPPF in December 2024.
Mrs Justice Lieven held that, when deciding a planning application, the footnote 7 part of the grey belt definition is tested against the actual development proposed. The decision-maker does not have to imagine every other development which might theoretically be built on the land.

What the Wrotham grey belt case concerned
Moto Hospitality proposed a secure 24-hour truck stop near junction 2A of the M26 at Wrotham in Kent, with parking for up to 197 HGVs, an amenity building, fuel station, access and landscaping.
The site was undeveloped Green Belt land near the Kent Downs National Landscape. Tonbridge and Malling Borough Council refused permission, but an Inspector allowed the appeal in February 2025 after the December 2024 NPPF had introduced the new grey belt policy.
Wrotham Parish Council challenged that decision. Both remaining grounds were dismissed.
The actual proposal matters when applying footnote 7
The grey belt definition excluded land where policies protecting areas or assets in footnote 7 would provide a strong reason for refusing or restricting development.
The Parish Council argued that the Inspector should have asked whether those policies would strongly restrict development generally on the site, not merely the truck stop actually proposed.
The court rejected that interpretation for decision-taking. A planning decision-maker is dealing with a specific application. Whether a National Landscape, heritage, habitats or other footnote 7 policy gives a strong reason for refusal will normally depend on the effects of that particular development.
Plan-making and decision-taking use the same definition in different contexts
Mrs Justice Lieven accepted that the same grey belt definition applies in both plan-making and development management, but the exercise is necessarily different.
When preparing a plan, an authority may have to consider whether development should be restricted on the land in broader terms. When determining an application, it asks whether the protected policy provides a strong reason to refuse the proposal actually before it.
The purpose of grey belt supported the Inspector’s interpretation
The judgment treated grey belt as a deliberately permissive change to Green Belt policy. Its purpose was to allow development on land which did not strongly contribute to specified Green Belt purposes where the other policy safeguards did not provide a strong reason for refusal.
An interpretation which required an Inspector to reject a proposal because some hypothetical, more harmful development might be unacceptable would work against that purpose.
The truck-stop need test did not require every component to be justified separately
The second ground concerned whether the fuel station was truly needed. The Inspector had found compelling need for HGV parking and driver welfare facilities in Kent.
The court held that the NPPF required demonstrable unmet need for the type of development proposed, not a separate proof of need for every component. In any event, the Inspector had rationally found the fuel station essential to the operation of the facility and consistent with the relevant strategic-road guidance.
Wrotham interpreted the December 2024 NPPF
The judgment is important because it establishes the approach to the grey belt definition, but the policy text quoted in the case was the December 2024 NPPF. A new NPPF was published in August 2026, so current applications should be checked against the current wording rather than relying only on the paragraph numbers in this judgment.
