Where the data comes from

Every report names its sources beside each finding, with the date it was read. This page lists them in one place, with the licence, so you can read the same records yourself.

Postcodes

postcodes.io, an open service built on Office for National Statistics and Ordnance Survey open data. Gives the coordinates, the council and the country for a postcode. Open Government Licence v3.0. https://postcodes.io

Planning

planning.data.gov.uk, the national planning data platform run by the Ministry of Housing, Communities and Local Government. Article 4 direction areas and conservation areas. The platform says itself that it is not yet complete for all of England, which is why a report says not checked when a council has published nothing. Open Government Licence v3.0. https://www.planning.data.gov.uk/dataset/

Law

Statutes are cited from legislation.gov.uk: the Greater London Council (General Powers) Act 1973, the Deregulation Act 2015, the Levelling-up and Regeneration Act 2023, the Town and Country Planning Act 1990 and the Welsh use class and visitor accommodation law.
