This dataset contains micro-level planning application records for local planning authorities (LPAs) in England covering the period 2001–2024. The data have been compiled to support the evaluation of inter-municipal cooperation (IMC) in local planning services and its effects on planning performance.
The dataset includes all planning applications submitted to LPAs that adopted shared planning services, as well as applications from neighbouring LPAs that did not participate in IMC arrangements, allowing for comparative and quasi-experimental analysis. For each planning application, the dataset records key administrative and procedural information, including application category, development scale, submission date, validation date, decision date, statutory target decision date, and indicators of delay, refusal, and appeal.
In addition, the dataset contains detailed information on institutional treatment status, identifying whether and when each local planning authority entered an inter-municipal cooperation arrangement.
