Statutory Auditors London

In the complex financial landscape of London, businesses often find themselves navigating between different types of audits to ensure financial transparency and compliance. Two significant audit types that play crucial roles in this regard are statutory audits and internal audits.

In this blog post, we will dive into the key differences between statutory auditors in London and internal auditors and explore the unique benefits each offers to businesses operating in the city of London.

Understanding Statutory Audit

A statutory audit is a mandatory examination of a company’s financial statements and accounts to ensure accuracy, compliance with regulatory requirements, and adherence to accounting standards. In the United Kingdom, companies meeting specific criteria are legally obligated to undergo a statutory audit. These criteria include turnover, assets, and the number of employees.

Key Characteristics of Statutory Audits:

  • Mandatory Requirement: Companies meeting certain thresholds are legally required to conduct a statutory audit. This ensures transparency, accountability, and the protection of stakeholders’ interests.
  • External Independence: Statutory audits are typically performed by external auditors who are independent of the company. This independence ensures an unbiased and objective evaluation of financial statements.
  • Compliance Focus: The primary goal of a statutory audit is to verify the company’s compliance with accounting standards, legal regulations, and corporate governance principles.
  • Issuance of Audit Report: After a statutory audit, the external auditors provide an audit report expressing their opinion on the fairness and accuracy of the financial statements.

Understanding Internal Audit

On the other hand, internal audits are conducted by an organization’s internal audit department or outsourced to external professionals. Internal audits serve a broader purpose beyond regulatory compliance, focusing on evaluating and improving the effectiveness of risk management, control processes, and operational efficiency within the organization.

Key Characteristics of Internal Audits:

  • Voluntary Nature: Internal audits are not legally mandated, and businesses can choose to conduct them at their discretion. Many companies opt for internal audits voluntarily to enhance internal controls and operational efficiency.
  • Performed by Internal or External Auditors: Internal audits can be conducted by the organization’s internal audit team or outsourced to external audit firms. The choice depends on the organization’s size, resources, and specific needs.
  • Operational Focus: Internal audits delve into various aspects of an organization’s operations, including risk management, internal controls, compliance with policies and procedures, and the efficiency of business processes.
  • Continuous Monitoring and Improvement: Internal audits are not one-time events; they are often part of an ongoing process aimed at continuous monitoring, identification of areas for improvement, and proactive risk management.

Key Differences between Statutory and Internal Audits

Mandatory vs. Voluntary:

  • Statutory Audit: It is a mandatory requirement for eligible companies.
  • Internal Audit: Conducted voluntarily by businesses to enhance internal controls and operational efficiency.

External vs. Internal Auditors:

  • Statutory Auditors in London: Performed by external auditors who are independent of the organization.
  • Internal Auditors in London: Conducted by an internal audit team or external auditors, depending on the organization’s preferences.

Focus of Examination:

  • Internal Audit: Focuses on operational efficiency, internal controls, risk management, and compliance with internal policies.


  • Statutory Audit: Results in the issuance of an audit report expressing the external auditors’ opinion on the financial statements.
  • Internal Audit: Typically results in a detailed internal audit report with recommendations for improvement but does not provide an opinion on financial statements.
