The Department for Work and Pensions (DWP) Secretary of State has principal responsibility for ONR governance, finance and performance in relation to conventional health and safety. A framework agreement signed by both organisations sets out the broad framework within which ONR will operate.
A number of other Secretaries of State are answerable in Parliament for aspects of ONR's activity, such as Secretary of State for Energy and Climate Change (as nuclear policy lead in the UK) and Secretary of State for Defence (in respect of ONR's work with MoD sites).
ONR has in place several Agency Agreements and MoUs. Agency Agreements are used to transfer statutory responsibilities whilst MoUs govern relationships with other bodies.
