A pig farm enforcement appeal in Norfolk has overturned a council notice over seven agricultural buildings, with the Inspector awarding full appeal costs against Breckland Council. The decisions, issued on 10 November 2026, turn on a distinction that can completely change the outcome of an enforcement case: was the development a breach of a planning condition, or something built outside the permission altogether?
Wayland Farms Ltd challenged the July 2025 notice concerning Cherry Tree Farm in Stow Bedon, where the farm had previously secured permission to expand pig production to 6,990 animals. Inspector A Walker allowed the enforcement appeal after an inquiry held in September and October 2026 and issued a certificate of lawfulness for the seven pig sheds, manure store and silos.
There is a twist. The separate appeal seeking retrospective permission to vary the approved plans condition was dismissed, even though the enforcement notice was quashed. The pig farm enforcement decision therefore has lessons about planning permissions, the applicable enforcement time limits, section 73A applications and the consequences of maintaining an unsustainable case.
Why the pig farm enforcement notice failed
The original permission, granted on 13 August 2019 under reference 3PL/2017/0878/F, authorised demolition of ten existing structures, seven new pig sheds with roof ventilation, and a new roof over an existing manure store. A condition required the approved plans to be followed. Breckland’s enforcement notice, issued on 9 July 2025, alleged that the new sheds did not comply with the approved elevations and required their construction with solid walls.
At the inquiry, however, the dispute reached well beyond the sheds’ walls. The Inspector accepted that demolition of the old buildings had been undertaken to implement the permission before it expired. But implementation of a permission does not establish that everything subsequently constructed was authorised by it. The key question was whether the completed works could fairly be described as the scheme that had received consent.
In considering the pig farm enforcement arguments, the Inspector examined comparison plans, site photographs and oral evidence. All seven sheds had been moved eastwards, by approximately 1 to 3.5 metres. The silos’ locations and configuration had changed, while further structures included a feed mixing shed, welfare unit, plant room and weighing platform.
The turning area extended approximately 443 square metres beyond the original application boundary. More importantly, the completed manure store was not simply an existing structure with a newly fitted roof: the Inspector found that it was a relocated and materially different building. The combined departures affected the layout, composition and physical form of the project.
A planning condition breach or unauthorised development?
That classification mattered. A failure to comply with the approved-plans condition would not necessarily be treated in the same way as operational development carried out without planning permission. Applying the law and the evidence, the Inspector found that the works fell materially outside the permission, rather than amounting merely to non-compliance with its second condition.
The decision draws on several existing Planning Geek Case Law authorities. Handoll and Suddick v Warner Goodman & Streat concerned the reach of conditions on a materially different building, while Commercial Land Ltd/Imperial Resources SA addressed the relationship between commencement works and development authorised by a permission.
For interpreting the permission, the Inspector also considered Trump International Golf Club Scotland Ltd v Scottish Ministers and Test Valley Borough Council v Chala Fiske. The important distinction was between implementation of an existing permission and determining whether later works still fell within that permission’s operative description.
Why the four-year immunity period was decisive
On the evidence, the development covered by the notice was substantially completed by mid-May 2021. The enforcement notice was issued more than four years later, on 9 July 2025. For these works, the Inspector applied the four-year limitation period and concluded that enforcement action had already become time-barred when the notice was issued.
The pig farm enforcement appeal therefore succeeded under section 174(2)(d) of the Town and Country Planning Act 1990. The Inspector considered that ground (b) would also have succeeded on the alternative approach, because the notice alleged breach of a condition where the development was materially outside the permission.
The notice was corrected and varied in its wording, then quashed. The Inspector also issued a certificate under section 191 confirming the lawful status on 14 November 2025 of the seven sheds, the manure store building and the silos. The certificate did not cover every additional item on the site, and its scope must not be read as a blanket approval of the whole farm.
Those dates are particularly important. The applicable four-year period in this decision reflects the planning and enforcement history of this development. It should not be treated as a general statement that every newly constructed building now becomes immune from enforcement after four years. Our lawful development certificate guidance explains why the precise works, evidence and relevant dates matter.
Why the section 73A appeal still failed
The farm had also appealed against refusal of application 3PL/2021/0932/VAR, which sought retrospective permission under section 73A to substitute revised plans for condition 2 of the 2019 consent. It was heard alongside the enforcement matter as appeal APP/F2605/W/25/3375849.
The Inspector dismissed that separate appeal. The original permission had been implemented, but the scheme as built was too different from the development authorised by the operative grant. Changing an approved-plans condition could not resolve a conflict with the very description of what had been permitted, notably the replacement rather than roofing of the existing manure store.
This reflects the Court of Appeal’s approach in Finney v Welsh Ministers, which limits the use of section 73 to change a permission’s operative description. In the separate costs decision, the Inspector also referred to Lambeth and Hillside Parks among the established authorities on interpreting planning permissions that the farm had put to the Council in August 2025.
There is no contradiction between the two results. A development can be lawful because enforcement time limits have expired, without a new permission being available through the particular variation route an applicant chose. Lawfulness arising through time and a fresh retrospective planning permission are distinct routes with different legal tests.
Full costs awarded against Breckland Council
The costs decision gives the case significance beyond the specific sheds. Inspector Walker made a full award against Breckland Council in connection with the enforcement and planning appeals. The Inspector found a sustained pattern of unreasonable conduct that caused Wayland Farms unnecessary expense and concluded that a full award of costs is warranted
. Not every individual complaint against the Council succeeded.
The farm had provided detailed submissions in August 2025 challenging the legal foundation of the notice. The Inspector concluded that the Council did not adequately reconsider its case in the light of those submissions and the relevant court authorities. By March 2026, the Council had also said it would not resist permission for the development as built, subject to conditions, yet continued to defend the notice.
Another serious issue was an allegation of positive deception, capable of affecting statutory immunity. The Council withdrew that allegation on the first day of the inquiry, after the farm had incurred expense preparing its response. The Inspector also criticised uncertainty in the demand for “solid walls”, which had evolved into “predominantly solid walls” without a clear measure of compliance.
The pig farm enforcement costs decision is a reminder that success or failure on a planning appeal does not, by itself, determine whether costs should be awarded. An authority must investigate and keep under review the actual legal foundation of its enforcement allegations. The Council was ordered to pay the farm’s appeal costs, to be assessed if the parties cannot agree the amount. No figure was specified in the decision.
The separate alternative costs application against a Rule 6 participant, Mrs Ann Cuthbert, was refused because the successful full award against the Council made it unnecessary to consider that alternative. Readers dealing with disputed appeal expenditure can find more on awards of costs in planning appeals and recovering a costs award.
What others can learn from the decision
The practical lesson from this pig farm enforcement case is to identify the alleged breach accurately before deciding how to defend it or regularise the works. The approved plans, the operative development description, the commencement evidence, the completion dates and the precise wording of an enforcement notice all matter.
It also shows why separate appeals must not be reported as a single win or loss. Here the enforcement notice failed, a limited lawful development certificate was issued, the section 73A planning appeal was dismissed, and the developer nevertheless secured a full costs award against the Council.
The inquiry decisions are dated 10 November 2026. The main enforcement appeal reference is APP/F2605/C/25/3375850; the accompanying planning appeal is APP/F2605/W/25/3375849. The official Planning Inspectorate records are available for the enforcement appeal and the planning appeal. The appeal decision is also available on AppealBase.
