Brownfield land register

In April 2017 the Town and Country Planning (Brownfield Land Register) Regulations came into force. These regulations place a requirement upon the Council, as Planning Authority, to publish a Register of ‘Brownfield’ (previously developed) sites and review the entries in the register at least once within each register year.

Latest data

Information is held on the Brownfield land register is available on DataShare, our home for open data.

What is this data?

Our Brownfield land registers provides an annual update of information on sites that we consider to be appropriate for residential development having considered the criteria laid out in Town and Country Planning Regulations 2017. The register includes brownfield sites that have full planning permission, outline planning permission and sites without planning permission that are considered suitable for residential development.

Government guidance suggests integrating this process with the existing Housing and Economic Availability Assessment (HELAA) work already carried out regularly. Sites must go through the same assessment of being suitable, available and achievable. The Council’s latest HELAA was published in September 2017 as part of the evidence base to support the Local Plan. The first iteration of Wycombe’s Register comprises of brownfield sites already assessed in the latest HELAA.


The dataset includes the following fields:

  • SiteNameAddress: the name and address of a site.
  • SiteplanURL: a URL to a web page (My Wycombe) giving a site plan for the site.
  • Hectares: the size of the land in hectares.
  • Deliverable: whether the site is considered to be ‘deliverable’.
  • PlanningStatus: the site’s planning status; for example does it have a planning permission.
  • MinNetDwellings: the minimum net number of dwellings that it is estimated the site should support.
