Openreach Limited is a company wholly owned by BT Group plc, that maintains the telephone cables, ducts, cabinets and exchanges that connect nearly all homes and businesses in the United Kingdom to the national broadband and telephone network. It was established in 2006 following an agreement between BT and the UK's telecoms regulator, Ofcom, to implement certain undertakings, pursuant to the Enterprise Act 2002, to ensure that rival telecom operators have equality of access to BT's local network.
Openreach manages BT's local access network which connects customers to their local telephone exchange, starting at the main distribution frame (MDF) in the exchange and ending at the network termination point (NTP) at the end user's premises. Openreach also manages the connections between the MDF and the BT Wholesale/local-loop unbundling (LLU) termination points located in the exchange, often referred to as jumper connections.
In March 2017, after various negotiations with, and demands from, Ofcom, BT plc agreed to divest Openreach's staff and non-network assets into a legally separate company, Openreach Limited. However, the network assets would still be owned by BT plc to ensure the longevity of leases and covenants, and Openreach Limited would still be wholly owned by BT plc's parent holding company, BT Group plc.
