Openreach, a privately owned UK-based company founded in 2006, is a subsidiary of BT Group. Employing approximately 35,000 people, it designs, builds, and maintains the United Kingdom's broadband network infrastructure. In 2023, the company reported revenues exceeding $1 billion, primarily from its enterprise connectivity services.
In the first half of 2025, data usage on the full-fibre network increased by over 35 percent year-on-year, while overall network traffic increased by 5 percent. Peak usage occurs between 8 pm and 10 pm. A Fortnite game update recently fuelled a surge in UK broadband demand, breaking nationwide usage records. This follows a warning from BT nearly two years prior about the need to coordinate broadcast and game downloads to manage infrastructure strain. In October 2024, a new telecare migration service launched, following a successful pilot program. This service will help service providers safely transfer vulnerable customers reliant on telecare devices to new full-fibre digital phone services before the Public Switched Telephone Network (PSTN) switch-off in January 2027.
