Provision of Planning Pipeline Data

MHCLG is looking to appoint a supplier of high-quality local planning data. From a functional perspective, the supplier is required to deliver an end-to-end data service covering the collection, enhancement, management, and provision of planning application and development pipeline data across England.

This includes gathering site-level data from Local Planning Authorities or third-party sources, enriching it with additional intelligence on development progress, and maintaining accurate records throughout the lifecycle of each site-from application through to construction and completion. A key requirement is the provision of multiple data outputs, including an initial full dataset, monthly updates capturing changes and new entries, quarterly analytical reports, and historical datasets extending as far back as possible.

Additionally, the supplier must support ad hoc analytical queries to meet urgent policy or ministerial needs. Suppliers must ensure that all data provided is accurate, validated, and fit for purpose, with clearly documented methodologies and consistent application of definitions.

Data completeness and quality are emphasised as central to the contract, with obligations to notify and resolve any quality issues within agreed timeframes. It is critical that the supplier must meet delivery schedules, such as providing monthly datasets and reports on agreed dates and ensuring that outputs remain current and reflective of real-world data.

The supplier must also demonstrate robust data management practices, including secure storage, GDPR compliance, and appropriate use of IT systems. The outputs / deliverables for this proposed contract are as follows: Planning pipeline dataset covering current residential and mixed-use sites in the planning system.

Monthly dataset updates showing site progressions, new entries, and re-permissions. Monthly change report summarising updates to the dataset.

Quarterly planning figures/reports on residential permissions, by region and site size. Historical planning/development dataset going back as far as available.

Polygonised site data/boundary files to support accurate site mapping. Local Planning Authority 5-year land supply views, including historical series.

Data glossary / documentation covering variables, definitions, codes, and metadata. Structured data access via API (including setup support and rate-limit details). Responses to ad hoc analysis queries from the Authority.
