How we’re organised

BT Group operates as a single business, made up of different organisational units. Our business is built around our customers – serving their needs and delivering value to them. We do this by rapidly developing and delivering innovative solutions; selling products and services that are an essential part of modern life.

We have three customer-facing lines of business: Consumer, Business and Openreach. They are supported by our internal service units, Digital and Networks.

We empower organisations large and small with secure and resilient connectivity. We unlock their potential to thrive and innovate anywhere in the world – connecting everyone to a brighter digital future.

In October 2018, Openreach became a legally separate company from BT, with our own board and strategy. The company is a wholly owned subsidiary of BT Group.

Even though Openreach is a separate company, it’s still part of our BT Group. And it’s job is to keep the UK’s fixed connectivity network in tip-top condition. Openreach connect our homes, mobile phone masts, schools, hospitals, broadcasters, and businesses of all shapes and sizes. It helps to create the best possible network with the highest quality service, for everybody.
