Parliamentary Archives

The Parliamentary Archives of the United Kingdom preserves and makes available to the public the records of the House of Lords and House of Commons back to 1497, as well as some 200 other collections of parliamentary interest. The present title was officially adopted in November 2006, as a change from the previous title, the House of Lords Record Office.

The over three million records are stored at The National Archives in Kew. Some of the most important constitutional records of the United Kingdom are in the collection, including the Petition of Right (1628), the Death Warrant of Charles I (1649), the Habeas Corpus Act 1679, the draft and final Bill of Rights (1689), the Slave Trade Act (1807 and 1833), the Great Reform Act (1832), and successive Representation of the People Acts. The archive was previously housed in the Victoria Tower at the Palace of Westminster, but was moved to its current location in 2025.

The archives also oversees records management for Parliament, has an active outreach programme and frequently appears on radio and TV programmes.
