In early 2021, there were just under 9,800 unique Conservation Areas in England (excluding sub-sections managed by secondary Local Planning Authorities), providing heritage protection for around 2.3% of England's land area and over 10% of properties.
This article was originally intended to provide a comprehensive list, arranged by ceremonial county and district / unitary authority, but the listing has remained incomplete (currently around 10% including external links) and has only been sporadically added to or maintained.
In mid-2017, the first comprehensive listing was published, accompanied by a range of supporting analysis, and made available as a PDF download or in spreadsheet format by the author.
This has subsequently been improved on by a new national spatial dataset, containing not only the names and key attributes of all English conservation areas, but also a full boundary dataset suitable for use in spatial analysis.
An official national spatial dataset for English conservation areas is maintained by Historic England, which makes copies available on request, although 4% of Local Planning Authorities are omitted and a further 20% have not currently granted permission to publish their data.
