Milton Keynes reports faster planning validation with Valon

AI system

System: Valon AI planning platform
Model: Not assessed
Release: Not assessed
Application developer: Valon
Role: Not assessed
Configuration: Not assessed
Inputs and outputs: Not assessed
Autonomy: Not assessed
Workflow: A group of council officers used Valon on live planning applications from October to December 2025. The system retrieved documents from the public planning register. Officers received training and gave feedback to the developer. [1] [2]
Human oversight: Not assessed
Relation to AI: The council used Valon to read and check planning documents and present information for officer review. The council and developer describe shorter processing times, but provide no reproducible analysis that isolates AI from case mix, staffing, or other workflow changes. Planning decisions remain officers’ responsibility. [1] [2]
AI contribution: Valon read planning documents, checked them, and presented information to officers. The council and developer report faster processing but do not isolate AI from differences in applications, staffing, or workflow. Officers retained responsibility for decisions. [1] [2]

Outcome identifiers: Not assessed
Benefit: Milton Keynes reports faster validation and decisions during its Valon pilot, with receipt-to-validation time falling from 15.8 to 7.6 days. [1] [2]
Category: Improved Organizational Efficiency
Status: Reported benefit
Beneficiary groups: Organizations. People. [1] [2]

Costs and harms: Not assessed

Conditions for replication: Officers must review the information that the system supplies and retain responsibility for planning decisions. The system must reflect the authority’s validation requirements and have access to the necessary application documents. Comparable timings and case characteristics are needed to determine whether similar savings recur. [1] [2]
Replication attempts: Not assessed
Later findings: 8 May 2026. The council reports that it purchased a one-year license after the pilot and that officers continue using Valon. Integration with Arcus is being scoped, and rollout to all planning officers remains an ambition. [1]

Access and versions: The original council and developer accounts are available, along with subsequent reporting. None links the underlying timesheets or statistical analysis. The developer’s page gives no publication date. [1] [2]
