State-owned enterprises of the United Kingdom
State-owned enterprises of the United Kingdom are organisations owned or controlled by the public sector that trade as market producers. In UK statistics, the Office for National Statistics (ONS) classifies market-producing entities under public control as public corporations, using control indicators and a "50% market test". Other publicly owned entities that are non-market are classified to central or local government. The statistical classification is distinct from legal form, which may be a Companies Act company, a statutory corporation or a body created by royal charter.
State ownership exists at central, devolved and local levels in the United Kingdom. Centrally owned examples include broadcasters, investment vehicles and infrastructure bodies; devolved holdings include rail, water and transport undertakings in Scotland, Wales and Northern Ireland. Channel 4 remained publicly owned following a 2023 government review and reforms.
As of October 2025, the Department for Transport’s holding group, DfT Operator Limited (DFTO), manages seven train operating companies in England under operator of last resort arrangements in the Railways Act 1993. Recent transfers saw South Western Railway (25 May 2025), c2c (20 July 2025) and Greater Anglia (12 October 2025) join London North Eastern Railway (2018), Northern Trains (2020), Southeastern (2021) and TransPennine Express (2023). DFTO replaced the former DfT OLR Holdings name in December 2024 and runs services under time-limited Service Agreements rather than franchises.
Recent changes include energy-system and nuclear-decommissioning reforms and the creation of new central investment bodies. The National Energy System Operator, a public corporation, took on system-operation functions on 1 October 2024; the Great British Energy Act 2025 established Great British Energy; the UK Infrastructure Bank was renamed National Wealth Fund Limited on 14 October 2024; and Magnox Ltd, a subsidiary of the Nuclear Decommissioning Authority, adopted the corporate name Nuclear Restoration Services in April 2024.
