We’ve been with Britain from the Industrial Revolution, through to the smartphone revolution. These archives tell our story. Our story begins in 1846 with the world’s first telegraph company and continues with BT today.
Answering the call of the past
Our archives don’t just tell the story of the world’s oldest communications company, they provide a fascinating insight into social changes over the past 175 years.
Through our extensive collection of advertising and marketing materials, you’ll catch glimpses of how all our lives have changed. You’ll marvel at our unparalleled library of phone directories. And you may (occasionally) gasp at our trove of documents showing how communication technology has moved from the novel to the ubiquitous.
We will be re-opening for visits from 6 July 2022
We will be open to pre-booked visits on Wednesdays and Thursdays. Please contact us to reserve your place. Note that we sometimes need to schedule closures on certain dates.
Our digital archive and catalogue
Can’t visit in person? Go digital.
The BT Digital Archives is our online research resource, the result of a £1 million collaboration between BT Heritage, Coventry University and The National Archives to digitise a core part of BT’s archive collection from 1846, almost half a million photographs, reports and items of correspondence preserved by BT over the past 167 years. Not everything has been digitised, but the entire collection can be searched. If what you want to see hasn’t been scanned, you can note the finding number and make an appointment to visit us.
