Every council is different. We know the differences.
Every planning application is a matter of public record. Search any of these councils' registers for our lead architect as agent and you will find the applications, the drawings and the decisions — going back more than a decade in Sutton, Croydon and Kingston.
Counts from each council's online planning register, September 2026. Some registers only hold recent applications or cannot be searched by agent.
