Our organisation

The holding company BT Group plc includes four separately managed businesses: BT Retail, BT Wholesale, BT Global Services, and Openreach. Each is supported by BT’s R&D, IT and network operations arms – BT Design and BT Operate.

Under the overall banner of BT Group, each of these businesses operates within a core market, as follows:

BT Retail provides telephones, mobiles, internet access and web-based services to residential and business customers. BT Retail has around 18,000 employees and 20 million customers.

BT Wholesale manages the UK’s core communications network, and provides network services and solutions to more than 600 UK communications providers, mobile operators and Internet service providers.

BT Global Services is a leading supplier of networked IT services operating globally and delivering locally to help our customers succeed.

Openreach ensures that all service providers have transparent and equal access to the nationwide local BT network – the "first mile" of wire that connects homes and businesses to BT exchanges across the UK.
