Regulation 4 of the Town and Country Planning (Brownfield Land Register) Regulations 2017 requires local Planning Authorities to publish brownfield land registers identifying land suitable for residential and mixed-use developments.
The Mayor is working with the London Planning Authorities to collate their individual registers as part of his commitment to using data and technology to make London an even better place to live, work and visit. They are not required to provide their registers for this map, so if you are unable to find the data for a particular planning authority, please check their website.
Please note that the GLA is not responsible for any of the data on the map or register. All sites have been identified by the local planning authorities (not the GLA). Sites included on the register which have not received planning permission have not been endorsed by the GLA or the Mayor. Where Part 1 sites do not have planning permission, planning applications will still be required, which will need to be judged against Development Plan Policies. The presence of a site on a brownfield register does not alter any current planning designation or pre-empt the plan-making process.
Further information on the Brownfield registers can be found on MHCLG guidance pages.
