R (Richard Dixon) v Wakefield Metropolitan District Council & Boom Developments Limited [2026] EWHC 1272 (Admin)

Dixon heritage reconsultation is a useful Planning Court judgment on three recurring issues: when planning officers can disagree with heritage specialists, how less-than-substantial heritage harm may be assessed, and when amendments or a change in national policy require fresh consultation.

The High Court upheld Wakefield’s permission for a solar farm in the Green Belt near the Grade II Bretton Hall Registered Park and Garden. Sir Tim Kerr rejected all three grounds of challenge.

What Dixon decided

Boom Developments applied for a renewable-led energy generating station comprising solar arrays and associated infrastructure on Green Belt land east of the M1. To the west of the motorway lies Bretton Hall Registered Park and Garden.

The council’s Design and Conservation Officer had raised heritage concerns and favoured refusal unless part of the array was reduced. The final officer report nevertheless recommended approval, relying on mitigation planting and the public benefits of renewable energy.

The planning committee granted permission in August 2025. A local resident challenged the decision, arguing that the council had no lawful basis for departing from the conservation advice, had failed properly to justify the heritage harm and should have reconsulted after revised planting and the December 2024 introduction of grey-belt policy.

The claim was dismissed.

Planning officers can disagree with specialist heritage advice

A conservation officer or statutory consultee provides important professional advice, but that advice does not itself determine the planning application.

Sir Tim Kerr held that the planning officers were entitled to form their own planning judgment provided they understood the heritage issue and gave an adequate basis for their conclusion. Different professional views emerging during an application are not evidence of illegality; they are a normal part of the planning process.

The court read the committee report fairly and as a whole rather than subjecting individual sentences to excessive forensic criticism.

Imprecise wording did not invalidate the report

The report found less-than-substantial harm to the registered park and garden, said the harm would not be fully mitigated, but later described the heritage impact as neutral. It also referred to section 66 of the Planning (Listed Buildings and Conservation Areas) Act 1990 even though that statutory duty does not apply to a registered park and garden merely because it is registered.

The court regarded those points as errors or infelicities rather than evidence that the committee had been materially misled. Read as a whole, the report identified the heritage harm, the mitigation and the public benefits and carried out the required balancing exercise.

Less-than-substantial harm did not need artificial precision

The claimant argued that the report should have calibrated more precisely where the harm sat within the broad category of less than substantial.

The court did not accept that national policy imposed a rigid requirement to assign a finer numerical or verbal sub-category in every case. What mattered was that the decision-maker understood the nature and degree of harm sufficiently to give it the weight required by policy.

The council did not have to redesign the application

The conservation advice had suggested removing or relocating some solar panels. The developer did not adopt that reduction and instead advanced additional planting as mitigation.

The council’s task was to decide the application before it. It was entitled to ask whether the mitigation proposed made the scheme acceptable rather than insist on designing a different scheme for the applicant.

Reconsultation was not automatically required

The additional planting responded to earlier heritage concerns but did not change the nature or scope of the solar-farm proposal. The court held that fairness did not require a new round of consultation merely because this mitigation had been added.

The same was true of the national policy change introducing grey belt. A policy change can alter the planning balance without altering the application itself. On the facts the claimant knew about the new material and policy position and had been able to make representations, so there was no material prejudice.

Planning Geek’s planning application reconsultation guide explains the wider fairness test.

Use Dixon carefully with later Green Belt policy

Dixon concerned the policy framework operating when Wakefield made its 2025 decision, including the grey-belt provisions introduced in December 2024. National Green Belt policy has changed again since then.

The lasting value of the judgment is therefore less about the precise policy wording and more about planning judgment, heritage advice, committee reports and procedural fairness.
