We preserve and provide access to BT's heritage from 1846 to today. The story of how the World's oldest communications company has used the power of communications to make a better world.
Records produced before the date of privatisation are public records under the Public Records Acts, 1958 and 1967. We undertake the company's statutory responsibilities under these acts to preserve and make available BT’s archives to members of the public after 20 years. BT Archives has been appointed an "official place of deposit for public records" for this purpose by the Lord Chancellor. BT Archives is also approved by The National Archives National Advisory Services as meeting their standard for archives repositories.
We also act as the corporate memory for the BT group of companies; vital historical information is preserved and made available where appropriate to aid BT's performance, raise the company profile and support BT as one of the world's leading communications services providers.
BT Archives has been located in its purpose built repository in Holborn Telephone Exchange since July 1997. This facility reflects BT's commitment to preserving and giving access to its unique and priceless archival collections.
