Common PSC Register Mistakes and How to Avoid Them

Failing to maintain an accurate PSC Register can expose your company to penalties and legal complications. Most errors happen because business owners misunderstand what information must be recorded or how often it should be updated.

A Person with Significant Control (PSC) plays a key role in ensuring transparency and accountability within a limited company. The UK Companies Act 2006 requires all companies to maintain a proper PSC Register, making it a vital part of statutory compliance. Yet, many businesses still struggle with errors that could have been easily avoided. This guide explores the most common PSC Register mistakes, their consequences, and how to fix them so your company stays compliant and efficient.

Understanding the PSC Register

The PSC Register, or Register of People with Significant Control, identifies individuals (or entities) who hold decisive influence over a company. Typically, this means anyone who:

• Holds more than 25% of shares or voting rights.
• Has the power to appoint or remove directors.
• Exercises significant control or influence, directly or indirectly, over company decisions.

The register is a statutory document that must be completed, maintained, and filed with Companies House. It ensures transparency about company ownership and helps prevent misuse such as money laundering or tax evasion.

For an in-depth overview of who must appear on the register, refer to our related guide on who must be listed in the PSC Register of a company (informational, topic-focused).

Why PSC Compliance Matters

Proper PSC compliance isn’t just a formality it’s a legal obligation. Failing to keep an accurate register can lead to:

• Civil or criminal penalties for the company and its officers.
• Filing rejections or administrative delays at Companies House.
• Reputational damage, especially for businesses under due diligence scrutiny.

The PSC Register forms part of the corporate governance structure that reassures customers, investors, and regulators of a company’s legitimacy and accountability.

The Most Common PSC Register Mistakes

Leaving the PSC Register Blank

One of the most frequent mistakes is leaving the PSC Register empty when a company is first incorporated. Some directors assume the register will remain “blank” until fully operational, but in reality, it must always contain a statement either confirming identified PSCs or noting that investigations are ongoing.

Even if your company has yet to identify any PSCs, you must include a statement such as “the company has not yet identified any registrable person.” Leaving it entirely blank is considered non-compliant.

Listing Incomplete or Incorrect Details

Each PSC entry must include precise personal information as required by law:

• Full name (matching official identification).
• Nationality.
• Service address.
• Date of birth.
• Nature of control.

Common errors include using abbreviated names, omitting addresses, or failing to describe the type of control clearly. For instance, stating “owns shares” is too vague; it should define the percentage bracket of ownership (“owns more than 25% but not more than 50% of shares”).

Accuracy ensures that the company’s register aligns with public data at Companies House.

Not Updating the Register Promptly

Another widespread issue is failing to record changes, such as a new shareholder crossing the 25% ownership threshold or resigning as a director.

The PSC register must be updated within 14 days of any qualifying change. Additionally, Companies House must be notified within another 14 days. Many businesses neglect these deadlines, assuming annual confirmation statements suffice. They do not. Each change triggers its own reporting requirement.

Confusing PSCs with Shareholders or Directors

While most PSCs are shareholders or directors, not all shareholders or directors qualify as PSCs. Some owners hold less than 25% of shares and therefore don’t meet the criteria.

Conversely, a person may not own shares but still exert significant influence, for example, through a shareholder agreement or loan condition granting decision-making power.

Understanding this distinction helps companies maintain accurate records and demonstrate compliance during audits or due diligence checks.

Failing to Record Registrable Relevant Legal Entities (RLEs)

A Relevant Legal Entity (RLE) is a corporate body that meets the PSC criteria and is itself required to maintain a PSC register. Businesses often forget to record these RLEs, assuming only natural persons qualify.

For example, if another limited company owns over 25% of your shares and is subject to PSC disclosure rules, that entity must appear in your register with the right identifying details.

This oversight is especially common in group structures or holding companies, where RLE identification can be complex but essential for full transparency.

Forgetting to Maintain Central Access for Inspection

The PSC Register must be available for inspection at your registered office or alternative inspection location. Many companies fail to keep it accessible or updated, violating statutory obligations under the Companies Act.

Even if your PSC information is publicly filed through Companies House, your internal register remains a separate legal requirement. Both must be accurate and consistent.

Relying on Outdated Templates or Systems

Some companies use legacy templates or digital systems created before legislative updates. Since PSC regulations have evolved, those older formats may miss mandatory fields or provide outdated terminology.

Form My Company often identifies such issues when assisting clients with PSC Register service support. Using professionally updated templates ensures every required field and statement aligns with current Companies House standards.

How to Avoid PSC Register Mistakes

Keep Clear Identification Processes

Before starting the register, establish a framework for identifying potential PSCs. Use objective criteria—such as share percentage, voting rights, and board control and verify these through official records and agreements.

Use Consistent and Verified Data

Ensure each PSC’s personal details match official documents. Verification prevents mismatched entries between your internal register and public filings. Maintain scanned copies of identification documents securely for compliance evidence.

Update Immediately After Changes

Integrate a PSCs monitoring checklist into routine corporate governance. Whenever a new director joins, shares are transferred, or rights change, review the PSC implications immediately rather than waiting for the year-end review.

Record Statements, Not Gaps

Even when identification is incomplete, always record the investigation status. Statements like “no registrable persons identified after reasonable steps” legitimize your compliance efforts and show that ongoing diligence is taking place.

Conduct Periodic Compliance Reviews

A quarterly or biannual review of your PSC Register alongside your statutory books helps identify discrepancies early. This is particularly valuable for companies under restructuring or those handling multiple shareholders.

What Happens If You Get It Wrong?

Non-compliance penalties can escalate quickly. Companies and officers who fail to maintain a compliant PSC register may face:

• Fines or prosecution under Sections 790F–790ZG of the Companies Act 2006.
• Difficulty with financial institutions during background checks.
• Administrative rejection of filings or delays in company transactions.

Even simple mistakes, like omitting a statement or misreporting a PSC’s nature of control can trigger enforcement actions. By implementing diligent recordkeeping and expert assistance, companies can avoid unnecessary regulatory complications.
