Security dog training at a former poultry farm near Royston has won permission on appeal after an Inspector rejected concerns that the operation needed a Stage 1 Road Safety Audit for its access from the A505. The retrospective change of use affects part of Bridgefoot Poultry Farm at Flint Cross, Cambridgeshire.
Inspector H Whitfield allowed appeal 6010543 on 16th October 2026 against South Cambridgeshire District Council’s refusal of application 25/03217/FUL. The approval is for keeping and training dogs for security purposes, not for altering the existing highway access or authorising any alleged unauthorised development elsewhere on the holding.
The decision matters because it distinguishes an application changing how land is used from a highway engineering scheme. The Inspector found that the national road-audit guidance relied on by the highway authority did not require a Stage 1 audit for this change of use, and that the low volume of vehicle movements had not been shown to create an unacceptable highway risk.
Why security dog training was refused in the first place
The appeal site comprises existing buildings and roughly 0.4 hectares of land on the southern side of the A505. The proposal sought retrospective consent to keep and train a maximum of eight security dogs at premises previously associated with poultry farming.
The A505 is a single-carriageway trunk road, with traffic travelling in both directions at the national speed limit. Access is via an existing gated opening. South Cambridgeshire District Council and the highway authority considered that daily journeys linked to the proposed dog use might exceed former agricultural movements and present additional safety risks.
The evidence described two members of staff and an occasional volunteer, with about four or five daily vehicle movements. There were no proposed dedicated delivery trips because staff undertook those functions. This relatively modest activity was central to the Inspector’s assessment.
One point of disagreement was the origin and lawfulness of the access. The appellant said it had been used since 2015, serving the former poultry operation. Some council evidence described it as informal or unauthorised. Crucially, the Inspector did not rule on that disputed legal status.
A road safety audit is not automatically required
The highway authority sought a Stage 1 Road Safety Audit under GG 119 of the Design Manual for Roads and Bridges, referring to traffic flows along the A505 and the potential impact of using an access onto that road.
The Inspector examined what the audit guidance actually covered. She noted that a highway scheme involves constructing a new highway or making a permanent change to an existing highway layout or features. The security dog training application involved no highway engineering works and proposed no new or altered access.
In the decision she stated that a change of use without such works would not constitute a highway scheme and would not necessitate a Stage 1 audit. That is the key distinction, not a general rule that a planning authority may never seek transport evidence for a change of use.
This point is especially useful for applicants converting existing rural buildings. A transport statement may still be appropriate where traffic effects warrant one, and any operational works could change the position. But a technical requirement intended for highway engineering cannot simply be asserted without explaining why it applies to the development before the decision-maker.
The evidence on traffic movements was too weak
South Cambridgeshire and the highway authority accepted that the access had existed for some time and had carried vehicles, but said former agricultural use would probably have generated relatively infrequent journeys. The appellant said the wider poultry operation had previously used farm vehicles and articulated lorries, potentially generating more traffic than the proposed dog use.
Neither side supplied empirical trip-generation evidence comparing the old and new operations. The Inspector therefore considered the actual material before her rather than treating either version as proved. Both sides accepted that at least some agricultural traffic could have used the access, while the proposed dog operation generated relatively few journeys.
She also examined the physical situation. The access was unmade, but the A505 was relatively straight in that location and there was reasonable visibility along the carriageway. The council had identified no specific geometric deficiency that would make the existing access unsuitable for the traffic associated with the appeal scheme.
Vehicles might need to wait before joining the main road, as they might with agricultural traffic, but that did not itself prove a greater accident risk. The Inspector concluded that there was no substantive evidence of a significant or unacceptable safety risk from security dog training on the site.
The finding accords with the August 2026 NPPF policy TR6, which addresses unacceptable highway safety impacts and severe effects on the transport network. It was not a blanket endorsement of new accesses onto trunk roads.
The appeal did not decide whether the access was lawful
This is a critical limitation on the decision. The Inspector expressly said a section 78 appeal about this change of use was not the forum for deciding the planning lawfulness of the existing vehicular access. That question would require separate determination under section 191 of the Town and Country Planning Act 1990.
Accordingly, the allowed security dog training appeal does not itself grant planning permission for the access, establish its lawful use or approve new highway works. It approves the identified change of use on the submitted plans, subject to conditions. Applicants considering similar sites should not mistake the appeal outcome for a certificate of lawfulness.
The Inspector also recorded that the emerging Greater Cambridge Local Plan remained at an early consultation stage and was not relied upon in the council’s refusal reasons. The adopted development plan and relevant national policy informed the decision.
Why noise, ecology and animal welfare did not defeat the appeal
Neighbours raised concerns about barking, disturbance, the condition of the premises, animal welfare and alleged activity elsewhere on the land. The closest home was described as roughly 100 metres to the east. The council accepted that the separation distance, road noise and limited proposed operation would not create unacceptable residential disturbance, and the Inspector agreed.
No substantive evidence showed that the buildings were unsuitable for keeping the animals or that staff were incapable of handling them safely. The Inspector also explained that animal welfare concerns fell beyond the planning issue she had to decide. Allegations about different uses or development on the wider property were similarly outside this appeal.
The Inspector recorded that biodiversity net gain did not apply to this retrospective permission under section 73A. That accords with the Government’s biodiversity net gain guidance. It should not be misunderstood as a general exemption for new dog facilities or all agricultural-to-commercial changes of use.
A suggested B8 storage condition was rejected because the application did not include a B8 use. An additional ecology enhancement condition was also rejected because its necessity had not been demonstrated for the change of use without operational development.
Eight dogs and flood works are enforceable limits
The allowed permission includes a clear numerical limit: no more than eight dogs may be housed or trained on the land at any one time. This directly addresses the traffic assumptions behind the appeal. The Inspector considered the modest scale of activity essential to the finding that the proposed use was acceptable.
A second condition requires the flood mitigation measures in section 5 of the January 2025 Flood Risk Assessment and SuDS Report, reference 4497 FRA-Bridgefoot Poultry Farm Revision B, to be completed within three months of the decision and retained. That makes the relevant deadline 16th January 2027, subject to the normal interpretation of the condition and any subsequent variation.
Other suggested restrictions did not make it into the permission. The Inspector declined a business-hours condition because the council had not justified its proposed hours and the separation from housing reduced the anticipated noise effects. She also refused a detailed access-scheme condition because the access itself was not part of the application and no material defects had been identified.
The security dog training approval is therefore narrow but practically significant. It permits the identified activity with measurable controls; it does not create a wider open-ended licence for a boarding operation of any size or for unrelated site uses.
What landowners can learn from the Bridgefoot decision
For rural conversions, the most persuasive evidence may be the actual number and nature of vehicle trips, the condition and visibility of an existing access, and whether a particular technical audit is genuinely relevant. Unsupported assertions about agricultural trip numbers are vulnerable in either direction.
I would also separate three questions at the outset: whether the existing access is lawful, whether the proposed new use is acceptable in highway terms, and whether any physical alteration to the access needs its own consent. They are connected issues, but one decision does not necessarily answer all three.
The security dog training outcome should interest operators of small rural animal-related businesses as well as planning practitioners, but it remains a fact-specific Inspector decision rather than a binding court precedent. It concerned limited vehicle movements, existing land and buildings and an unaltered access onto the A505.
Appeal 6010543 was decided on 16th October 2026 by Inspector H Whitfield. The application was 25/03217/FUL, and permission is subject to the eight-dog ceiling and flood mitigation condition. Those details, rather than the mere fact that a dog-training business succeeded, explain the significance of the decision.
