The Legislation.gov.uk API, maintained by The National Archives, provides open access to the full text of UK legislation from 1267 to the present day. The database covers over 100,000 items including Acts of Parliament, Statutory Instruments, Scottish and Welsh legislation, and Northern Ireland statutes. All data is available as structured XML with Dublin Core metadata, Atom feeds, and HTML. The API supports point-in-time versions showing how legislation read at any given date, plus amendment tracking.
No authentication or API key is required. The API is fully open. Respect rate limits by adding reasonable delays between bulk requests.
