BT Archives preserves the historical information of British Telecommunications plc and its predecessors from the early part of the nineteenth century up to the present day, effectively the history of telecommunications services in the United Kingdom and from the UK to overseas.

Records produced before the date of privatisation are classed as public records under the Public Records Acts, 1958 and 1967. BT Archives undertakes the company's statutory responsibilities under these acts to preserve and make available public records to members of the public after 30 years, and for purpose has been appointed an "official place of deposit for public records" by the Lord Chancellor. BT Archives is also approved by The National Archives National Advisory Services as meeting their standard for archives repositories.

BT Archives also acts 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 providers of telecommunications services.
