Internal Audit Careers: Roles, Qualifications and Salaries in 2026
What internal audit involves as a career, how it differs from external audit, and how ACCA and CIA qualification fit.
What Is Internal Audit?
Internal audit is an independent assurance and advisory function within an organisation that helps it achieve its objectives by evaluating and improving the effectiveness of risk management, control, and governance processes. Unlike external audit (which focuses on the accuracy of financial statements for shareholders), internal audit serves the board and management — with a broader remit covering operational risks, IT risks, compliance, fraud prevention, and strategic risks.
Internal vs External Audit
External auditors (typically Big 4 or mid-tier firms) are appointed by and report to shareholders, focusing on financial statement accuracy. Internal auditors are employees or co-sourced providers reporting to the audit committee and management. Internal audit has broader scope, greater flexibility to focus on emerging risks, and a more advisory culture — though the independence imperative is equally important.
Career Path in Internal Audit
Graduate/Internal Auditor → Senior Internal Auditor → Audit Manager → Head of Internal Audit → Chief Audit Executive (CAE). In large organisations, the CAE is a senior leadership role reporting directly to the Audit Committee Chair and attending board meetings. Salary for CAE at a FTSE 100: £150,000-£250,000.
Qualifications for Internal Audit
ACCA and ACA are common qualifications among internal auditors, particularly those who have moved from external audit. The CIA (Certified Internal Auditor) from the IIA (Institute of Internal Auditors) is the globally recognised specialist internal audit qualification — highly valued at senior internal audit levels. CISA (Certified Information Systems Auditor) from ISACA is valuable for IT audit specialists. Many internal audit functions fund both ACCA and CIA.
