How to become a financial auditor: role, routes, skills and salary

The quick route to becoming a financial auditor

The typical path has five stages: choose a relevant degree or an apprenticeship after your A-levels; reach degree level in accounting, finance, business or a related subject; train towards a professional qualification (ACA, ACCA or CA) under a training contract; gain supervised audit experience; and start as a trainee or associate auditor, most often in an accountancy firm.

What to know before you start: degree level is the norm, although school-leaver apprenticeships now offer a route without university first. A trainee in a large firm earns around £30,000 to £35,000 in London. The qualities that matter most are accuracy, professional scepticism, and the discipline to work to tight deadlines.

What does a financial auditor do?

A financial auditor is the professional who examines a company's financial statements to confirm they are reliable and free from material error. Their opinion gives lenders, investors and regulators confidence in the figures a company publishes.

Statutory audit and other assurance work

Financial audit takes two main forms. A statutory audit is required by law for certain companies: the auditor forms an independent opinion on the annual accounts and signs the audit report. Other assurance and advisory engagements are carried out at a client's request, for example during an acquisition or a fundraising round.

Where financial auditors work

Most auditors start in an accountancy firm, from the Big Four networks to mid-tier and regional practices. Others work in-house, in companies, banks or the public sector. The firm route remains the classic way in, because it trains you quickly and exposes you to many sectors.

Why audit matters

Without audit, no independent party would vouch for the figures a company reports. The auditor protects confidence in the market, helps prevent fraud and error, and tests the quality of internal controls. That usefulness explains the steady demand for these profiles.

A financial auditor's day-to-day work

The work is organised around audit engagements, with a peak in workload around clients' financial year-end and reporting deadlines.

• Plan the engagement: understand the client's business, identify the areas of risk and set out the work.
• Test transactions and controls, checking supporting evidence and the strength of internal control.
• Analyse large volumes of data to spot anomalies, errors and inconsistencies.
• Document the work, draw conclusions and report findings to the client.
• Work alongside finance and accounting teams, the auditor's main contacts throughout the engagement.

External audit or internal audit: what is the difference?

Audit covers two related but distinct jobs, depending on whether you work for an outside client or for your own employer.

The external auditor, in a firm

The external auditor works for an accountancy firm, serving several client companies. They bring an independent view and, in a statutory audit, sign the audit report. This is the most common way to start a career.

The internal auditor, in an organisation

The internal auditor is employed by the organisation they review. They assess risk, the effectiveness of processes and compliance with procedures on an ongoing basis, and report to senior management and the audit committee. The role is closer to advice than to certification.

What skills do you need to become a financial auditor?

The job calls for a solid technical base and genuine personal qualities.

Technical and data skills

Accounting and financial analysis are the heart of the work: you need to read a balance sheet and a profit and loss account and judge whether they hold together. Knowledge of UK GAAP (FRS 102) and IFRS is expected, along with audit methodology. Comfort with technology counts more every year: advanced Excel, accounting systems and ERPs, and data-analytics and audit software. Good written and spoken English is essential, and a second language helps in international firms.

Personal qualities

Accuracy and professional scepticism are decisive, because the auditor has to spot what is wrong without letting anything slip. Organisation keeps you on top of tight reporting deadlines, and the ability to explain findings clearly matters when you report to people who are not auditors.

What qualifications do you need to become a financial auditor in the UK?

This is the central question. The profession is reached at degree level, and several routes lead to it.

The graduate route

The most common path is a degree, often in any discipline, though accounting, finance and business help, followed by a professional qualification taken with an employer. An international business degree taught in English is a strong foundation here. A bachelor's such as the Global BBA at SKEMA, a four-year programme with finance specialisations, builds the grounding in accounting and management that audit work draws on, while the Master in Management offers an Accounting Expertise and Audit track for students who want to focus early. For a specialisation aimed squarely at the profession, the MSc Auditing, Management Accounting & Information Systems, taught in English, covers external and internal audit and counts the Big Four among its recruiters.

The professional qualifications

In the UK, the degree is only the start: you then qualify through a professional body. The main qualifications are the ACA (ICAEW), the ACCA, the CA (ICAS) and, for management accounting, the CIMA. You sit professional exams and complete supervised work experience under a training contract with an employer, usually over about three years. The ACCA is a global qualification, which suits students who study or work internationally.

The apprenticeship and school-leaver route

You do not always need to go to university first. A Level 7 accountancy apprenticeship, the degree-equivalent route, runs for around five years towards the ACA or CA while you work and earn, and the Big Four and many firms run school-leaver schemes such as BrightStart. Entry typically asks for GCSE maths and English at grade 4 or above, plus A-levels or equivalent UCAS points. The AAT qualification is a common first step at a lower level.

Becoming a registered (statutory) auditor

Signing statutory audit reports is regulated. A registered auditor is a firm registered with a Recognised Supervisory Body, namely ICAEW, ACCA, ICAS or Chartered Accountants Ireland. Anyone who signs audit reports must be a responsible individual holding a practising certificate and the audit qualification, earned through exams and supervised audit experience. The profession is overseen by the Financial Reporting Council (FRC); a replacement regulator, the Audit, Reporting and Governance Authority, has been proposed, but as of 2026 the reform remains on hold.

How much do financial auditors earn in the UK?

Pay is one of the profession's strong points, and it rises quickly with experience. It depends on the type of firm, its size and the region.

According to recruitment salary guides and ICAEW data for 2025, a trainee earns roughly £30,000 to £35,000 in London during ACA training, with UK trainee accountants ranging from about £22,500 to £37,000. A newly qualified auditor earns around £55,000 on average, and £51,000 to £56,000 in London public practice. An audit manager earns £60,000 to £80,000, rising to £70,000 to £95,000 in the Big Four in London.

Several factors move these figures. The Big Four tend to pay more than regional firms, and salaries are higher in London than in the regions. Many auditors also see a rise of 15 to 30 per cent when they move from practice into a company after qualifying.

Career progression and where audit can take you

Audit is recognised as a career accelerator: after a few years in a firm, auditors move easily into other areas of finance.

Progression in a firm

The path in a firm is well marked: you start as an associate, become a senior, then a manager, and on to director or partner for those who stay. Each step adds responsibility for clients and for the people you manage.

Moving into a company

After a few years in audit, many move into a company in financial control, financial planning, risk or advisory roles. The cross-cutting view of accounts and risk that audit gives you is highly valued. A degree such as the MSc Corporate Financial Management prepares for these corporate finance roles, where auditing is one of the listed career outcomes.

Specialisations

You can also specialise by sector or by field, in internal audit, IT and data audit, or sustainability assurance. A markets-focused path, such as SKEMA's MSc Financial Markets & Investments, ranked second worldwide in the 2026 Financial Times Finance ranking, leads instead towards financial analysis and investment banking.

Auditor, accountant, internal auditor: what is the difference?

These finance roles sit close together but are not the same.

The external auditor checks the accounts that a company has produced and forms an independent opinion on them. The accountant prepares and keeps those accounts: they produce the information that the auditor then reviews. The internal auditor, employed by the organisation, looks beyond the accounts at risks and processes across the business, all year round rather than at year-end.
