Case Study: IT Governance, Controls & Assurance
Strengthening IT controls and operational assurance for a UK energy supplier
Turning complex regulatory, IT and operational requirements into practical controls that can be understood, evidenced and sustained.
A long-term assurance partnership built for resilience
Pragmatic supports a UK energy supplier through an ongoing programme of IT controls, income assurance and operational governance. The work combines detailed process walkthroughs and operating-effectiveness testing with practical remediation, helping teams strengthen ownership, improve evidence and embed controls into business as usual. Beyond identifying gaps, we help translate regulatory and governance expectations into proportionate actions that support billing accuracy, revenue assurance, audit readiness, resilient operations and informed management decision-making.
Building a robust IT income controls framework
End-to-end revenue control
We examine billing and revenue processes from transaction initiation through invoicing, reporting, reconciliation and General Ledger recording, confirming that controls work in practice as well as on paper.
Connected systems, clear accountability
We assess interfaces between operational, billing and finance systems, alongside reconciliations, manual adjustments and exception management, to improve accuracy, traceability and timely resolution.
Evidence that stands up to scrutiny
We strengthen segregation of duties, evidence retention and control ownership, creating clear records that support management assurance, audit activity and continuous improvement.
Operational assurance support
Turning control insight into practical improvement
Control Gap Identification
Identify missing, inconsistent or ineffective controls across IT, operational and revenue processes before they become wider assurance issues.
Exception Assessment
Review control exceptions, assess their potential impact and distinguish isolated incidents from recurring operational risks.
Root Cause Analysis
Investigate why issues occur, examining process design, system behaviour, ownership and cross-functional hand-offs.
Remediation Planning
Create proportionate improvement plans with practical actions, evidence requirements and realistic milestones for delivery.
Ownership & Prioritisation
Assign accountable owners and prioritise actions according to risk, customer impact, regulatory expectations and operational urgency.
Action Tracking & Reporting
Track remediation through to closure, maintaining clear status reporting that gives management meaningful assurance and visibility.
Stronger IT governance. Greater operational resilience.
Effective IT governance depends on more than policies and technical controls. It requires clear decision-making between IT and Operations, consistent escalation routes and a shared understanding of the systems and suppliers that support critical services.
Pragmatic helps strengthen these foundations by reviewing recurring incidents, clarifying accountabilities and improving how operational risks and technology decisions are identified, discussed and resolved. We support teams in managing third-party dependencies, ensuring vendor arrangements, resilience expectations and recovery requirements are visible and understood.
Through practical application governance, we help establish an authoritative view of the application estate, including ownership, criticality, security posture, resilience and key dependencies. The result is a more joined-up approach to governance that supports better decisions, stronger oversight and a more resilient service for customers and stakeholders.
Information Security Assurance Programme
A practical security workstream that builds governance, evidence and resilience into day-to-day technology and operational management.
Security Framework and Certification Readiness
The programme develops an Information Security Management System (ISMS) that gives leaders a structured way to identify security risks, assign accountability, maintain policies and demonstrate that controls are operating. It connects recognised security expectations with the systems, suppliers and operational processes that matter most.
ISMS Development
Establishes the policies, risk assessment approach, control ownership, governance routines and evidence needed to operate an effective security management system.
Cyber Essentials to ISO 27001
Aligns current practices to Cyber Essentials, prepares the organisation for Cyber Essentials Plus validation and sets out a proportionate roadmap towards ISO 27001 readiness.
Implementation Guide
The security programme begins by defining the scope of the ISMS, including critical applications, information assets, operational teams, third-party services and key dependencies. Security risks are assessed against business impact, ownership is assigned and policies are reviewed against recognised standards such as ISO 27001 and NIST2. The resulting framework documents required controls, expected evidence, review cycles and escalation routes so that security governance can be maintained as part of business as usual.
Evidence That Supports Assurance
Cyber Essentials alignment focuses on core technical safeguards, including secure configuration, access control, malware protection, patch management and supported software. Preparation for Cyber Essentials Plus adds validation of how those safeguards work in practice. The ISO 27001 roadmap then prioritises the further governance, risk, supplier, incident-management and continual-improvement activities required to build a mature, auditable ISMS without creating unnecessary administrative overhead.
