Registering and maintaining an accurate People with Significant Control (PSC) position is a core corporate governance obligation for UK companies. As scrutiny from Companies House and HMRC increases, errors or omissions in UK company PSC filings can lead to compliance failures, financial penalties, and reputational risk. This guide provides practical insights for finance teams and company secretaries on correct PSC registration, the evidence required, and how to avoid common mistakes in filings and updates.
Understanding PSC Obligations in the UK
The PSC regime was introduced to enhance transparency over who ultimately controls UK companies. Under the Companies Act 2006 (as amended by the Small Business, Enterprise and Employment Act 2015), all UK companies (except certain listed entities) must identify, verify, and register individuals or legal entities with significant control. This includes anyone who holds more than 25% of shares or voting rights, has the right to appoint or remove a majority of the directors, or otherwise exercises significant influence or control over the company.
Companies are legally required to:
- Take reasonable steps to identify PSCs
- Record PSC details in the company register
- File accurate PSC information with Companies House
- Keep information up to date and file changes within 14 days
What Evidence is Required for PSC Filings?
Accurately evidencing a PSC position is more than a formality. Companies are expected to maintain robust records demonstrating their efforts to identify PSCs and the basis on which they conclude an individual or entity meets the criteria. This documentation is critical for demonstrating compliance during a Companies House or HMRC review, and forms a key part of effective UK company PSC filings.
Evidence typically includes:
- Share registers and transfer records
- Shareholder agreements or articles of association
- Board minutes documenting control rights or appointments
- Correspondence with shareholders regarding PSC status
- Identification documents for individual PSCs
- Due diligence records for relevant legal entities
Finance and secretarial teams should store this evidence securely, and review it before each filing to ensure ongoing accuracy. In practice, a lack of clear documentary evidence is a frequent reason for queries or delays by Companies House. For example, in a recent case, a technology SME was unable to demonstrate its steps to identify an overseas PSC, resulting in a compliance investigation and a warning notice. Maintaining a clear audit trail is essential.
Registering a PSC: Process, Timing, and Best Practice
PSC information must be entered into your company’s statutory register as soon as the company has identified a PSC or registrable relevant legal entity (RLE). You must then file this information with Companies House within 14 days using form PSC01 (for individuals), PSC02 (for RLEs), or PSC03 (for changes to PSC details). Failure to file on time is a criminal offence for both the company and its officers, with enforcement actions ranging from financial penalties to prosecution.
- Verify the PSC’s identity and the nature of their control
- Notify the individual or entity of their status
- Update the company’s internal register and statutory records
- Submit the appropriate form to Companies House in a timely manner
It is essential to check that all data matches supporting evidence, and that forms are filled in precisely as required. Common pitfalls include mismatched names, outdated addresses, and unclear descriptions of the nature of control. Using a checklist and assigning responsibility within your team can help avoid oversights. In one real-world example, a manufacturing business faced penalties after a clerical error led to a PSC’s name being misspelt across two filings, highlighting the importance of verifying every detail.
Updating PSC Information: Common Scenarios and Mistakes
Changes in shareholdings, restructuring, or new shareholder agreements may trigger a change in PSC details. Companies must track such changes and update both their internal register and Companies House records within 14 days. UK company PSC filings are often queried due to:
- Delaying updates until the next confirmation statement
- Failing to recognise indirect control via other legal entities
- Inaccurate recording of the nature of control
- Omitting to notify PSCs of their status or changes
- Incomplete supporting evidence for new or departing PSCs
For example, if a PSC sells part of their holding and falls below a 25% threshold, a PSC07 form must be filed to reflect cessation of that PSC status. In a recent case, a services company failed to notify Companies House after a restructuring moved control to a parent entity abroad. This oversight led to an official investigation and required the company to submit additional evidence and explanations. Any subsequent changes that might reinstate PSC status must also be promptly filed.
Real-World Challenges for SMEs and Growth Companies
Smaller and fast-growing companies often encounter complexities such as dormant shareholders, nominee arrangements, or overseas structures. The obligation to “take reasonable steps” means you must make and evidence genuine efforts to trace beneficial owners, even when information is hard to obtain. If, after due diligence, no PSC can be identified, a statement to that effect must be filed with Companies House.
Some practical steps for SMEs include:
- Regularly reviewing shareholder and director changes after each transaction round
- Documenting all attempts to contact potential PSCs or their representatives
- Seeking professional advice for complex or cross-border shareholdings
Recent real-world examples highlight the risks: a growing fintech company delayed updating its PSC register after a funding round, resulting in a compliance review and the need to file a late change notice. More complex cases—such as trusts, joint holdings, or indirect control—often require specialist input. In such scenarios, leveraging legal and compliance guidance can help ensure your approach is robust and defensible.
Compliance Checks and Enforcement: What to Expect
Companies House, and in some cases HMRC, may conduct spot checks on UK company PSC filings. Inaccurate or missing filings are treated seriously. Enforcement action can include:
- Financial penalties for the company and responsible officers
- Criminal prosecution in cases of wilful non-compliance
- Public record notations of breaches, affecting company reputation
Appeals against penalties or enforcement actions are possible, but require clear evidence that reasonable steps were taken and that any errors were inadvertent. For example, a retail company successfully appealed a penalty by producing correspondence proving timely efforts to clarify a PSC’s status. To prepare for possible audit, companies should ensure their PSC register is always up to date, that supporting evidence is readily accessible, and that all filings are consistent with the company’s statutory records. Routine internal reviews and periodic training for finance and secretarial staff are strongly recommended.
Companies that rely on digital solutions should ensure their Systems and Technology infrastructure supports timely updates and secure record-keeping for PSC data.
Integrating PSC Compliance with Broader Governance
Effective PSC compliance is best viewed as part of a wider governance and risk management framework. Companies should align PSC procedures with broader corporate record-keeping, shareholder management, and regulatory reporting processes. Outsourcing to a specialist provider of corporate company secretarial services can streamline compliance, especially for complex or multi-entity structures.
Conclusion
Registering and maintaining accurate UK company PSC filings is a statutory obligation that requires careful attention to evidence, ongoing updates, and a proactive compliance culture. By embedding robust internal processes, learning from real-world pitfalls, and seeking specialist guidance when needed, UK companies can avoid common errors, reduce risk, and demonstrate sound financial governance.
