BT Archives

We're in it together' Post Office Public Relations poster

We conserve and make accessible BT's heritage, going all the way back to 1846. We document and preserve the story of the world's oldest communications company.

All the records we produced before privatisation in 1984 are public records. BT Archives has been appointed an "official place of deposit for public records" by the Lord Chancellor and approved by The National Archives National Advisory Services as meeting their standards for archives repositories.

We also act as the corporate memory for the BT Group, retaining vital historical information to benefit the company. 

Visiting us

BT Archives has been in a purpose-built repository in Holborn Telephone Exchange since July 1997.
