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. The table has been retained at the foot of this article, as it provides a holding structure for a number of useful local links, but its usefulness has been largely superseded by other sources.
