London Development Database Automation Project


The London Development Database Automation Project will streamline how planning application data travels from applicants, through London’s 35 local planning authorities (LPAs), to City Hall, and out to the public:

Our ambition is to create a ‘live hub’ of planning and development information, accessible to all Londoners by reforming the information we collect and the way we collect it. We will request the data we need for monitoring up front, on the initial planning application. This data will pass seamlessly into authorities’ improved back-office systems, where planners will verify it, and then automatically out of those systems to City Hall and onto a public website.

This automation should reduce borough workloads, allowing data to travel easily between systems rather than requiring officers to manually populate the London Development Database (LDD) by locating information that’s buried in supporting documents, as often occurs now. The Ministry of Housing, Communities and Local Government’s Local Digital Fund is supporting the project. You can read more about next steps and timelines here.

Planning Data Standard

Currently, planning applications do contain the vast majority of data required by City Hall to monitor the planning process and coming development, as well as for public use. However, this information is held in supplementary documents and text fields that make it difficult to locate. Instead, the information required for monitoring purposes will now be collected on planning applications in machine-readable fields to allow for automation.

City Hall provided London’s 35 Local Planning Authorities an opportunity to comment on our Draft Planning Data Standard, available here for reference. The consultation closed on 14 February 2019. We have reviewed every comment sent by London's planning authorities and provided a response to each, which you can read here. We have also answered the five cross-cutting questions that appeared in multiple responses. The link to these is forthcoming.

Following consultation, we have produced an Combined Planning Standard that takes the consultation responses into account, you can download this using the button below.

We have also produced a Technical Planning Data Standard with further information on schema, fields, and other relevant details.
