The Oscar Research Public Sector Intelligence Hub brings together research on UK Government and Public Services, including NHS structural change, Local Government reorganisation, public sector structure, practical market guides and Oscar's historical change archive. It connects current organisations and decision-makers with the structural history that explains how responsibilities, relationships and public sector markets have evolved.
Public Sector Intelligence built from research over time
Oscar Research has researched UK Government and Public Services since 1984. Alongside maintaining current organisational and postholder data, we retain structural and historical context that helps explain what changed, what replaced it and where responsibility moved.
Use the Hub for recent intelligence and living resources, practical guides to the public sector market, or to move backwards through the historical archive.
Hub reviewed: September 2026 · Historical resources retain their original publication context.
