Hilltop Experiences v Norfolk County Council: alternative sites, officer reports and the limits of error of fact

The Court of Appeal has dismissed a challenge to Norfolk County Council's grant of planning permission for a replacement Household Waste Recycling Centre ("HWRC") near Cromer, confirming that an officer's report is not rendered unlawful merely because it failed to identify a specific alternative site, provided the report expressly acknowledges that suitable alternatives outside the designation may exist.

The judgement, handed down on 6 May 2026 ([2026] EWCA Civ 541), concerned a permission granted in June 2024 for a 0.45-hectare HWRC on land within the Norfolk Coast National Landscape. The appellant, Hilltop Experiences Limited, operates an outdoor education centre for some 10,000 children annually — around 1,000 of whom have special educational needs — and objected on the basis that the planning officer had failed to consider East Beckham Quarry, a site approximately 600 metres from the application site and situated outside the National Landscape designation.

The quarry came to light after the first judicial review hearing, when the landowner contacted the appellant having read about the proceedings in the local press. Email correspondence then emerged showing that the interested party's consultants had made repeated attempts in 2019 to arrange a site visit with the landowner, who had initially expressed interest but had not responded to meeting requests. The case officer, Mr Zieja, had misidentified the quarry referenced in the planning statement as the Beeston Regis Quarry rather than East Beckham Quarry.

Lord Justice Dove, with whom Lords Justice Miles and Zacaroli agreed, identified two potential errors of fact. The first — whether the landowner had genuinely failed to engage — was found not to meet the threshold for established fact under the principles in E v Secretary of State for the Home Department [2004] QB 1044. Given that no meeting had been arranged despite repeated offers of dates, and that site selection had concluded during 2020, it was reasonable to characterise the position as one of non-engagement at the material time.

The second error — the failure to identify East Beckham Quarry as a potential alternative outside the National Landscape — was found to be immaterial for a more fundamental reason. The officer's report had itself acknowledged that the site selection exercise was insufficiently robust and that suitable sites outside the National Landscape designation might exist. The recommendation to grant permission was therefore made explicitly on the basis that such alternatives could not be ruled out. That acknowledged uncertainty was treated as a negative factor in the planning balance; the other material advantages of the scheme were found to outweigh it regardless.

Applying Mansell v Tonbridge and Malling Borough Council [2017] EWCA Civ 1314, the court held that the report was not significantly or seriously misleading. The absence of a reference to East Beckham Quarry did not distort the members' decision-making because the report had not proceeded on the false premise that all potential alternatives lay within the National Landscape.

The judgement reaffirms that the adequacy of an alternatives assessment is primarily a matter of planning judgement, reviewable only on Wednesbury irrationality grounds. It further illustrates that where an officer's report openly concedes the deficiency of an alternatives exercise and factors that uncertainty into the planning balance, the subsequent emergence of a specific unexamined site is unlikely to disturb the permission. The decision will be of practical relevance wherever planning committees grant permission for departures from development plan policy in sensitive landscape designations, on the express basis that the case for refusal on alternatives grounds cannot be made with certainty.
