We’re BT’s internal service unit, and we’re responsible for delivering and operating BT’s networks, platforms and IT systems.
We work closely with each of BT’s customer-facing lines of business to create new products and make sure that existing services evolve to meet the needs of their customers.
And we’re always looking towards the future – we manage most of BT’s research and development, and are responsible for BT’s worldwide patent portfolio of more than 4,500 patents and applications.
We’re continuing BT’s long history of innovation. In 1926 we held the world’s first two-way, trans-Atlantic conversation by radio telephone from our wireless station near Rugby. And in 1943, Tommy Flowers, working in the telecommunications division of the General Post Office (as we were at the time), developed the world’s first programmable electronic computer, Colossus.
In 1968, we installed the world’s first digital telephone exchange. We laid the world’s first, purpose-designed optical fibre submarine cable in Loch Fyne, Scotland in 1980.
We’re building on this great legacy to keep developing and delivering the technology that will allow BT’s customers to thrive in a fast-changing world.
This year we upgraded our core IP network to handle record volumes of data traffic in the UK. Our IT reliability has improved for the fourth consecutive year and the operational reliability of our core voice and broadband network platforms has hit a five-year high.
We’re also responsible for managing the group’s energy consumption and for putting strategies in place to cut the group’s carbon footprint. We’ve reduced energy usage for six consecutive years*.
*We’ve restated our worldwide energy consumption and GHG emission figures for previous years following improvements to our data. Previous estimates of energy usage have been updated with measured figures.
