Oxford Investigation Service (OIS) is an award-winning counter-fraud service operating within Oxford City Council and supporting more than 40 local authorities, housing providers and public sector organisations across the UK.
Recognised nationally for excellence counter-fraud, innovation and partnership working, OIS combines decades of investigative experience with cutting-edge data analytics, intelligence development and fraud prevention techniques. Our team brings together over 150 years of specialist counter-fraud expertise, helping organisations identify, prevent and investigate fraud risks across a wide range of service areas.
In an era of increasing financial pressures, every pound lost to fraud is a pound unavailable for frontline services. OIS helps public sector organisations protect vital resources, strengthen governance and maximise value for money. In 2025, our work delivered financial outcomes measured in millions of pounds through fraud prevention, investigation, recovery and wider deterrence activity.
Whether you’re looking to enhance an existing counter-fraud function, access specialist investigative expertise, or commission a fully managed service, OIS offers a flexible and scalable solution tailored to your organisation’s needs.
