Medium and large-sized companies are generally required to have a statutory audit. Recent legislation has increased the thresholds, meaning fewer businesses now need an audit.
As of April 2025, a company may be exempt if it meets at least two of these three criteria in a financial year:
- An annual turnover of £15 million or less
- Total assets of £7.5 million or less
- 50 or fewer employees
Companies exceeding two of these thresholds are classed as medium or large and must have an audit.
However, many audit-exempt companies still choose to get one done, finding benefits in having a review of their systems and controls.
