Statutory Audit: definition, exemptions and benefits

When a business reaches a certain point, a statutory audit is required. The Audit needs to be conducted by an independent and qualified auditor and is a legal obligation.

The statutory Audit must be carried out for every year that a company is not exempt. It aims to provide an opinion on whether the financial statements issued by the organisation are free from errors (or material misstatement).

Who needs a statutory audit?

The audit eligibility criteria are set out in the UK government's Companies Act 2006. 

• Your company generates a turnover greater than £15 million
• The value of your company's gross assets exceeds £7.5 million
• Your company employs more than 50 people

If a business's financial year starts before 6th April 2025, and you're a non-group company, it must conduct an annual Audit if it meets any two of the criteria in that year:

• Your company generates turnover greater than £10.2 million
• The value of your company’s total assets exceeds £5.1 million
• Your company employs more than 50 people

Are UK subsidiaries expected to complete audits? 

While some companies in the UK are exempt as a result of not breaching the above thresholds, some companies may still require an Audit, such as some UK subsidiaries of foreign parent companies.

This is because the parent company may require an Audit for consolidation purposes, or due to legal or regulatory requirements in their own country. It's important for companies in these situations to seek professional assistance to ensure they comply with all necessary Audit and reporting requirements

The Audit report must be accessible to the company's shareholders and available at the company's annual general meetings. The report must also be filed with Companies House.

Statutory Audit exemptions

Not every company requires a statutory audit. The following are exempt:

• Dormant companies (that have not traded during the financial year)
• Small companies, if their financial years begin on or after 6th April 2025 and at least two of the following apply:
  
  • an annual turnover of no more than £15 million
  • assets worth no more than £7.5 million
  • 50 or fewer employees on average
• Small companies, if their financial years begin between 1 January 2016 and 5 April 2025 and at least two of the following apply:
  • an annual turnover of no more than £10.2 million
  • assets worth no more than £5.1 million
  • 50 or fewer employees on average

Companies still need to prepare financial statements, even if they are exempt from the Audit. A qualified accountant can help ensure your financial statements are done properly.

What is the difference between an internal Audit and a statutory Audit?

While sounding similar, an internal audit and a statutory audit have some key differences.

An internal audit is carried out by a company's own employees (hence "internal"), while an independent auditor does the statutory audit.

How to choose an auditor for your statutory Audit

An auditor must be a member of a recognised supervisory body, such as:

• Institute of Chartered Accountants in England and Wales (ICAEW)
• Association of Chartered Certified Accountants (ACCA)

An auditor with experience working with companies of the same size, complexity and industry as the company that they are auditing is also beneficial.
