AuditOne

What AuditOne does

AuditOne is a values-based, not-for-profit NHS consortium established in 2016 through the merger of four regional NHS audit consortiums, with predecessor organisations dating back to the 1980s. The company provides risk-based internal audit, counter fraud, digital risk assurance and workforce advisory services to over 60 organisations, primarily across the UK NHS and broader public sector including charities, private healthcare providers and national regulators. Service delivery is organised around three core lines — Internal Audit, Counter Fraud, and Internal Audit (Digital) — supplemented by two wholly-owned sub-brands: WorkforceOne, which delivers HR, conflict resolution and investigation services, and ConsultOne, which provides board-level consultancy such as NHS Well Led reviews.

The firm employs approximately 100 staff across five North East England and Cumbria offices (Stanley HQ, Durham, Newcastle, Stockton and Carlisle) and delivers an average of 9,000 days of assurance and advisory services each year. Its counter fraud and criminal investigation teams carry over 250 years of combined experience and produce more than 1,000 counter fraud recommendations annually, with criminal investigation services provided to over 25 NHS organisations. The Digital Internal Audit practice is positioned as the largest public sector IT audit provider in the North of England, offering cyber security, network penetration testing, cloud security and data analytics under a Digital and Data Strategy programme.

AuditOne operates on a professional services model as a consortium, generating revenue through quote-based contracts with NHS and public sector clients and reinvesting surplus under its not-for-profit status. Go-to-market is direct and relationship-led, with services distributed through established NHS consortium relationships rather than channel partners. Marketing activity is modest, relying on a corporate website, LinkedIn, YouTube fraud-awareness content and a twice-yearly Fraud Insight newsletter. The company holds no patents or trademarks and discloses no funding rounds; ownership is implicitly held by member NHS organisations.
