London Development Database: Monthly Planning Permissions Submitted by Borough

London's monthly planning permissions data from the London Development Database (LDD), submitted by the city's boroughs. The dataset counts permissions involving residential unit changes or large non-residential schemes, serving as an indicator of planning system activity. It is maintained by the Greater London Authority and was last updated on 2026-07-08, with the CSV file automatically refreshed on the first day of each month.

Use Cases

• Track monthly construction activity trends based on the count of planning permissions.
• Analyze borough-level variations in development submissions based on the data source.
• Model the pipeline for residential housing supply based on permissions involving a gain or loss of units.
• Monitor the approval lifecycle for large non-residential projects based on the 1,000m2 floorspace or 7+ bedroom thresholds.

Strengths

• Data is updated automatically on a monthly schedule, as stated in the description.
• Focuses on significant developments via defined thresholds for residential changes and large non-residential schemes.
• Includes an interactive map for spatial visualization of all LDD permissions.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• Borough data submissions are not always timely, and totals are subject to change as data is checked and missing permissions are added.
• Permissions may represent revisions or renewals of existing projects, not exclusively new schemes.
