The Oscar Research database is a continuously maintained database of UK public sector organisations and named postholders. It is researched by people rather than populated through automated scraping, and can be selected by sector, organisation type, seniority, job function, responsibility, geography and other criteria. Continuous research since 1984 also gives Oscar historical knowledge of public sector organisations and, where available, postholder career journeys.

Oscar Research owns and maintains its own UK public sector database. Since 1984, we have researched, built and continuously maintained our own database of UK public sector organisations, named postholders, structures, responsibilities and contact information.
The data we supply comes from Oscar Research's own continuously maintained research database. It is built, structured and maintained by our team, giving us direct control over the quality, organisation and context of the data we provide.
Our researchers track changes across Government and Public Services, including organisational structures, responsibilities, senior roles and named postholders. That means we understand the context behind the records, not just the contact fields.
Buying directly from Oscar gives you access to the people who research, structure and maintain the data. If you have an unusual targeting requirement, a question about a record or need help defining an audience, you are speaking directly to the source.
