The Planning DataHub is a collaborative project between all of the Planning Authorities in London to build a single open data set of development proposals in the planning process to enable monitoring of how our City is changing and develop a shared understanding of the data.

The dataset is owned and contributed to by everyone in the planning and development industry and would not be possible to produce unless all parties contribute towards it.

Whilst the DataHub itself is purely a dataset, we have enabled access to the data in a number of ways to make it useful and usable to everyone. This is an evolving area of work at present so please watch for changes as they happen.

Data on the datahub is data that is supplied by applicants and Planning Authorities. Due to the nature of how it is collected and assimilated, it is not checked for quality as it is received, and as such may require to be amended as data quality reviews are completed and specific analysis highlights deficiencies. Boroughs supply starts and completions data on an annual basis.

We are currently running a data improvement program, increasing the availability and quality of the data. If you are looking to use this data for analysis please review the core data for any error before relying on it.
