Sensitive and Complex Case Review Service

Independent reviews enhancing efficiency, reduce organisational risk, and protect operational integrity.

Independent case reviews that provide clarity, assurance and strategic insight IGS offers a structured and confidential review service for complex and sensitive matters across law enforcement, public and private sector bodies. Our reviews are specifically designed to meet the expectations of internal leadership teams, oversight bodies, regulators, and legal stakeholders. Each engagement is tailored to the client’s terms of reference and delivered by experienced professionals with subject matter expertise across a wide range of operational and governance areas.

Delivering tailored, impartial reviews across the private and public sectors.

In a climate of increasing financial constraint and public scrutiny, public bodies face growing pressure to demonstrate value, transparency, and accountability.

Our structured review methodology helps senior leaders meet these demands by providing clear, evidence-based findings and practical, forward-focused recommendations. Each review is designed to support informed decision making, protect institutional reputation, and strengthen public confidence.

IGS delivers tailored, impartial reviews of high-risk, sensitive and complex matters across the public and private sectors. Our service is designed to support organisations in addressing operational challenges, managing reputational risk, and embedding learning that leads to improved outcomes. We specialise in sensitive, complex, and serious and organised crime (SOC) reviews, post-incident assurance, insider threat evaluations, and investigations into conduct, governance, or procedural concerns.

IGS brings together senior practitioners with extensive experience in policing, national law enforcement, and complex investigations. This combination of operational  credibility and structured independence ensures that our reviews deliver both depth and objectivity, with outcomes that support lasting improvement.

  • Protecting core services and frontline delivery

    Through the identification of inefficiencies, duplication, and procedural gaps, our reviews enable better alignment of resources and allow organisations to redirect capacity where it is most needed. This ensures continued delivery of essential services, particularly in environments constrained by financial or operational pressures.

  • A proactive approach to risk management & organisational resilience

    Engaging IGS delivers tangible benefits that extend far beyond the review period. Our work is structured to support improved decision-making, reduced financial exposure, and enhanced operational performance. In doing so, we enable senior leaders to meet both their strategic objectives and their statutory responsibilities.

  • Reducing the likelihood of litigation and associated costs

    Sensitive investigations, particularly those involving serious crime or professional conduct, often carry legal and reputational risks. Our independent reviews provide organisations with well-evidenced findings that strengthen internal governance and significantly reduce the likelihood of legal claims or regulatory challenge.

  • Preventing unnecessary escalation of risk and expenditure

    Unresolved issues can develop into large-scale incidents with complex, costly consequences. Our review methodology is designed to identify emerging risks and recommend timely interventions that prevent escalation, safeguarding both public trust and financial sustainability.

  • Providing assurance to executive leaders and oversight bodies

    IGS provides support to the investigation leads and assurance to senior and accountable officers. With clear, independent findings that enhance assurance across executive leadership, scrutiny panels and external regulators, supporting transparency and building institutional credibility.
