A message from our Chief Executive

Sharpening our focus

I’ve spent the last few months meeting as many of our customers, stakeholders and colleagues as possible. This has deepened my appreciation of the fantastic assets that make BT unique.


We provide the digital backbone for the nation. Without us, life as we know it stops. It’s why everything we do has to be focused on supporting the customers who rely on us, and living up to our purpose.
