Local Planning Authorities are required to prepare and maintain registers of previously developed (or brownfield) land.
The sites on the register are considered to be suitable, available and achievable for residential development in line with the criteria set out in The Town and Country Planning (Brownfield Land Register) Regulations 2017.
The definition of previously developed land is set out in the National Planning Policy Framework.
The data is provided under the Open Government Licence.
The sites listed in the register are those eligible sites which had planning permission at 31 March 2020 or were allocated for development in the Adopted Local Plan.
Brownfield Land Registers are required to be reviewed every year. The register was last reviewed in December 2020.
Having a site listed in the register does not mean it has been granted planning permission.
