Not every UK limited company needs a statutory audit. Many smaller companies qualify for audit exemption, but it is important to understand the rules, as an audit may still be required in certain situations.

For financial years starting on or after 6 April 2025, a company is generally audit exempt if it qualifies as a small company and meets at least two of the following conditions:

• Annual turnover of no more than £15 million
• Balance sheet total (gross assets) of no more than £7.5 million
• Average number of employees of no more than 50

If a company exceeds these limits, it will not usually lose audit exemption straight away. In most cases, the company must exceed the thresholds for two consecutive financial years before the exemption is lost.

However, some companies must have an audit regardless of size. This includes public companies and certain regulated businesses, such as banks, insurance companies, and some investment firms.

An audit may also be required if the company’s shareholders request one. Shareholders holding at least 10% of any class of shares, or 10% of voting rights, or 10% in number of members, can demand an audit. This request must be made in writing and received at least one month before the end of the financial year.

Charitable companies are subject to different rules and often face lower thresholds for mandatory audits. For example, a charity may require an audit once its gross income exceeds £1 million, depending on its circumstances.
