The UK’s Economic Crime and Corporate Transparency Act (ECCTA) has entered its final stage of implementation, shifting the landscape of corporate criminal liability and audit oversight.
How does the new corporate criminal liability regime affect audit cycles?
The ECCTA, described by Pinsent Masons as the most significant reform to corporate criminal law since the 2010 Bribery Act, forces a change in how boards interact with their auditors. The legislation, which began its three-stage rollout on 1 September 2025, makes “failure to prevent fraud” a corporate criminal offense. For companies, this means they must proactively demonstrate the existence of robust fraud prevention frameworks.
David Lister notes that this shift fundamentally alters the auditor-client dynamic. “When issues arise the outcry is often ‘where were the auditors, how did they not spot this?'” Lister said. “But now with ECCTA audit firms can place the onus and burden of fraud back on their clients.” Auditors are expected to “shadow” any ongoing fraud investigations within a client firm, meaning that businesses under active investigation will face significantly higher levels of scrutiny during autumn audit cycles and year-end reporting.
Why is Companies House scrutiny increasing for businesses?
Beyond the internal fraud offense, the ECCTA grants Companies House expanded powers to verify, query, and reject corporate filings. Historically, the registrar accepted filings largely at face value, but the new regime allows for active intervention when inconsistencies appear. Hinesh Shah, a forensic accountant at Pinsent Masons, warns that this change will create a new layer of transparency that auditors will inevitably monitor.
“As Companies House undertakes greater scrutiny of filings, inconsistencies between information submitted to the registrar and information contained within audited financial statements, annual reports or governance disclosures may become more visible,” Shah said. Consequently, auditors are likely to focus on the controls and verification processes that support any public disclosure, as discrepancies could signal broader governance failures to regulators.
What are the risks for public companies?
For publicly traded organizations, the stakes of the ECCTA extend beyond potential criminal liability to include market valuation and litigation risks. David Lister warns that fraud-related investigations can directly impact share prices and lead to shareholder litigation. Boards must now ensure that their internal “reasonable procedures” are not just documents, but active, embedded governance processes.
The quality of investigation work is under heightened scrutiny. Auditors are now expected to probe deep into how a board manages its fraud risk, especially in environments where regulatory queries or anomalies have already emerged. Organizations that fail to align their public filings with their internal financial reporting may find themselves facing challenging, protracted conversations with their audit committees.
Frequently Asked Questions
Does the ECCTA apply to all companies?
The legislation applies to organizations that must demonstrate “reasonable procedures” to prevent fraud by associated persons, including employees, agents, and subsidiaries. It is designed to drive behavioral change across all firms, with specific implications for those undergoing audits.

What happens if a company’s filings are inconsistent?
Under the new powers granted by the ECCTA, the registrar at Companies House can now query information, demand supporting evidence, and reject filings. According to Hinesh Shah, this makes the consistency between regulatory filings and audited financial statements a priority for directors and auditors alike.
How should boards prepare for the next audit cycle?
Boards should re-examine their fraud prevention processes and ensure they have adequate legal and accounting advice. David Lister emphasizes that auditors will be paying close attention to fraud risk management programs, particularly where there are ongoing financial crime investigations.
