Where the site is
The registered site centre point, the local planning authority that published the entry and its local reference, so the record can be traced back to source.
Brownfield land register
England's brownfield land register, searchable site by site
Local planning authorities in England must publish a register of previously developed land they consider appropriate for residential development. We hold those registers in one searchable database so each site can be found, filtered and appraised alongside the rest of your evidence.
What each register record holds
What the authority recorded
Site area in hectares, recorded minimum and maximum dwelling capacity, deliverability and ownership status, exactly as published — never inferred.
Planning status
Whether permission is recorded, the permission type and the register dates held against the entry. Where a field is not published we say so rather than assume it.
The official source
Every record links to the MHCLG Planning Data service entry it came from, published under the Open Government Licence v3.0.
How the register is used
Find previously developed land
Screen an area for sites an authority has already accepted as previously developed, before spending time on greenfield promotion.
Test a site against the register
Check whether a site you are already assessing appears on its authority's register, and what capacity was recorded for it.
Take it into a full appraisal
Carry a register entry straight into the site analysis, policy evidence and residual appraisal tools rather than starting again.
Before you rely on a register entry
What this dataset covers
- The register covers previously developed land the authority considers suitable, available and achievable for housing.
- It is not a list of every vacant, derelict, contaminated or previously developed site.
- Smaller sites may not be included.
- Data may contain missing fields or outdated entries.
- A centre point is not a surveyed ownership or planning boundary.
Brownfield register information is provided for initial site screening. Inclusion in Part 1 does not grant planning permission. Part 2 and permission-in-principle status must be verified with the relevant local planning authority. The local authority register and planning register remain the authoritative sources.
