Data Auditing Services

We provide data auditing services for regulated industries across the UK, delivering assurance for financial services, insurance, telecoms, and energy clients. Our senior consultants are qualified Lead Quality Auditors to ISO 9001 and conduct comprehensive Information Governance Audits. These go beyond a basic compliance check and assess data quality, ownership, retention, access controls, and reporting processes to identify weaknesses before they escalate into regulatory penalties or operational risks.

With over 20 years' expertise in GDPR, UK regulatory frameworks, and industry best practice, we deliver clear, actionable findings and practical remediation roadmaps. The outcome is not just regulatory protection, but also greater trust in your data, stronger decision-making, and a foundation for long-term business value.

Identifying Problems and Delivering Full-Scope Solutions

In today's strict regulatory climate, failing to maintain accurate, documented, and GDPR-compliant data processes can result in severe fines and reputational damage. Many organisations struggle with uncontrolled data flows, incomplete lineage, poor retention practices, and outdated documentation — all of which compromise audit readiness and business agility.

Our team provide full-scope Data Audit Services designed to uncover and address these challenges. Our consultants combine technical rigour with commercial insight to evaluate data quality, ownership, lineage, access controls, and reporting processes. This ensures weaknesses are identified and remediated before regulators can act.

The result is more than compliance: we deliver clarity, control, and confidence in your data assets, strengthening governance frameworks and enabling organisations to operate with resilience in a fast-changing environment.

What ABCA Delivers in Data Compliance Auditing

Pre-Audit Checks for Regulatory Readiness

We carry out rigorous pre-audit checks to make sure your organisation is fully prepared for scrutiny under regulations such as GDPR and BCBS239. Our team reviews your existing controls, governance documentation, and operational processes, enabling you to identify and resolve compliance gaps before regulators even begin their review.

Data Lineage and Documentation Reviews

Understanding exactly where your data originates, how it flows through your organisation, and where it is stored is crucial for compliance. We conduct in-depth data lineage reviews and thorough documentation assessments, bringing transparency and accountability to your data management. This approach supports GDPR-compliance and strengthens your ability to demonstrate information governance to auditors.

Quality Auditing to ISO 9001 Standards

At AB Consultants and Analytics, we apply recognised ISO 9001 standards when auditing your data processes. Our quality audits focus on finding any process or control weaknesses that could expose your organisation to risk. This detailed approach not only supports compliance but helps improve efficiency and reduces the chance of costly operational errors.

Data Quality Standards Frameworks (ISO 8000)

High data quality is fundamental to reliable decision-making and compliance. We use ISO 8000 frameworks to assess the accuracy, completeness, and reliability of your data, ensuring that your organisation can trust its information. Our approach to data quality auditing builds lasting confidence among stakeholders and demonstrates your commitment to best practice management.
