Dixon v Wakefield: High Court dismisses solar farm challenge on Yorkshire green belt land

The High Court has dismissed a judicial review challenge to the grant of planning permission for a solar farm on green belt land in West Yorkshire, in a judgement that touches on the newly introduced grey belt concept and the limits of procedural fairness obligations in the planning process.

Sir Tim Kerr, sitting as a judge of the High Court, handed down his judgement on 29 May 2026 in R (Dixon) v Wakefield Metropolitan District Council [2026] EWHC 1272 (Admin), rejecting all three grounds of challenge brought by local resident Richard Dixon against the council's decision to permit Boom Developments Limited to construct a solar array and associated infrastructure east of the M1 motorway.

The site sits in green belt land with a direct visual relationship to the Grade II listed Bretton Hall Registered Park and Garden (RPG), a designed landscape of national significance located to the west of the motorway. The case therefore engaged both renewable energy policy and the sensitive framework governing harm to registered historic parks and gardens.

Heritage officer overruled

At the centre of the first two grounds was the council's decision to grant permission despite the sustained objections of its own Design and Conservation Officer (DCO), Emma Sharpe, who had consistently argued that the westward-facing solar panels on the northern portion of the "western parcel" would cause unjustified harm to the setting and significance of the RPG. The DCO considered that planting alone would be insufficient mitigation and maintained that a reduction in panel numbers was necessary.

The claimant argued that the planning officer's report failed to provide adequate reasoning for departing from that specialist advice, and that the report contained material errors, including a misplaced reference to section 66 of the Planning (Listed Buildings and Conservation Areas) Act 1990 -- a provision applicable to listed buildings rather than registered gardens -- and the use of the phrase "neutral impact on heritage" in circumstances where harm had been conceded.

Sir Tim Kerr declined to find these errors legally significant. The section 66 reference was "a minor error without consequence." The phrase "neutral impact on heritage" was "a wrong use of language that misled no one." Officers had not been required to agree with the DCO, whose views had been fairly presented to the planning committee. The Yorkshire Gardens Trust, as statutory consultee, had itself moved toward accepting additional planting as adequate mitigation by November 2024, and officers were entitled to adopt that position.

On the second ground, concerning whether the LPA had properly engaged with the possibility of reducing panel numbers, the court found the issue had been addressed in the report. The developer had refused to reduce the scheme for economic viability reasons, and the LPA was not obliged to consider a diluted version of the application.

Grey belt and procedural fairness

The third ground raised the question of whether the council should have reopened public consultation following the developer's February 2025 amendments and its revised green belt assessment in April 2025, which sought to reclassify the site as grey belt under the new December 2024 NPPF framework.

Sir Tim Kerr rejected that argument. The proposal for additional planting was not new; it had been suggested by the Yorkshire Gardens Trust in 2024. The claimant had been aware throughout of all material submissions and had responded to them. The introduction of the grey belt concept, while lowering the threshold for the developer, did not alter the nature or scope of the application and did not, in itself, generate a common law duty to consult afresh.

Applying the principles from R (Holborn Studios Ltd) v London Borough of Hackney [2017] EWHC 2823 (Admin), the court found no material prejudice to the claimant. His submissions in May and July 2025 demonstrated full awareness of the changed policy landscape.

The claim was dismissed and the claimant ordered to pay the council's costs, capped at £5,000 including VAT.
