What Is a Person with Significant Control (PSC)? A Complete Guide for UK Company Owners

If you're setting up a UK limited company, you'll almost certainly come across the term Person with Significant Control (PSC). It appears during the incorporation process, on Companies House records, and in your ongoing compliance obligations.

For many first-time founders, the concept can be confusing. Does every shareholder count as a PSC? Is a company director automatically a PSC? What happens if ownership changes? And why does Companies House require this information in the first place?

The answers are important because identifying PSCs correctly is a legal requirement for most UK companies. Failing to do so can result in compliance issues, financial penalties, and difficulties when opening business bank accounts or working with regulated service providers. This guide explains what a Person with Significant Control is, who qualifies, how PSCs are identified, when you must report changes, and what every UK company owner should know.

What Is a Person with Significant Control (PSC)?

A Person with Significant Control (PSC) is an individual or legal entity that owns or controls a UK company. The UK introduced the PSC register to improve corporate transparency and make it easier to identify the people who ultimately control companies. Every eligible company must identify its PSCs, maintain accurate records, and submit the required information to Companies House. Importantly, not every shareholder or director is a PSC. A person only qualifies if they meet specific legal conditions.

The Short Answer

A Person with Significant Control (PSC) is someone who has substantial ownership or influence over a UK company. In most cases, a person is considered a PSC if they:

• Own more than 25% of the company's shares
• Hold more than 25% of the voting rights
• Have the right to appoint or remove most of the directors
• Exercise significant influence or control over the company
• Control a trust or firm that meets one of these conditions

Companies must identify and report PSCs to Companies House as part of their legal compliance obligations.

Why Does the PSC Register Exist?

The PSC regime was introduced to increase transparency in corporate ownership. Before its introduction, it could be difficult to determine who ultimately controlled some companies, especially where ownership passed through multiple entities or nominee arrangements.

The PSC register helps:

• Improve corporate transparency
• Combat financial crime
• Reduce money laundering risks
• Strengthen trust in UK businesses
• Help regulators identify company controllers

For legitimate businesses, maintaining accurate PSC information demonstrates good corporate governance.

Who Qualifies as a PSC?

A person qualifies as a PSC if they satisfy at least one of five legal conditions. Let's examine each one.

Condition 1: Owning More Than 25% of the Shares

This is the most common route to becoming a PSC. For example, a company has 100 shares:

• Sarah owns 60 shares.
• James owns 40 shares.

Both own more than 25%. Both are PSCs. By contrast:

• Emma owns 20 shares.

She would not qualify under this condition.

Condition 2: Holding More Than 25% of Voting Rights

Sometimes ownership and voting rights differ. A shareholder may own a smaller percentage of shares but have enhanced voting rights under the company's Articles of Association. If someone controls more than 25% of voting rights, they are generally considered a PSC.

Condition 3: The Right to Appoint or Remove the Majority of Directors

Control is not always based on share ownership. If someone has the legal right to appoint or remove most of the company's board of directors, they may qualify as a PSC. This often arises through:

• Shareholder agreements
• Investment agreements
• Special constitutional rights

Condition 4: Significant Influence or Control

This is one of the broader PSC tests. A person may qualify even without owning shares if they exercise significant influence over how the company operates. Examples may include someone who:

• Directs major business decisions behind the scenes
• Exercises dominant influence over directors
• Controls strategic decision-making despite not being formally appointed

Whether someone satisfies this condition depends on the specific facts and circumstances.

Condition 5: Control Through a Trust or Firm

Ownership is not always direct. Sometimes shares are held through:

• Trusts
• Partnerships
• Other legal arrangements

If an individual ultimately controls these structures and they satisfy one of the PSC conditions, that individual may also be regarded as a PSC.

Are Directors Automatically PSCs?

No. Being a director does not automatically make someone a PSC. Consider these examples:

• Example 1: Lisa owns 100% of the company and serves as the sole director. She is both a Director and a PSC.
• Example 2: Michael is hired as Managing Director but owns no shares. He manages daily operations but has no ownership or controlling rights. He is not a PSC.
• Example 3: An investor owns 70% of the shares but has no operational role. They are not a director, but they are clearly a PSC.

Ownership and management are separate legal concepts.

Are All Shareholders PSCs?

No. Only shareholders meeting one or more PSC conditions qualify.

Although all three are shareholders, only the first two meet the ownership threshold.

What Information Must Be Reported?

Companies must record certain details about each PSC. This typically includes:

• Full name
• Date of birth
• Nationality
• Country or state of residence
• Service address
• Nature of control
• Date the individual became a PSC

While some information is published on the Companies House register, sensitive personal information such as the full residential address, is generally protected from public disclosure.

When Must PSC Information Be Updated?

PSC information should be kept accurate throughout the life of the company. Updates are required whenever:

• Ownership changes
• Shares are transferred
• New investors join
• Voting rights change
• A PSC leaves the company
• Control arrangements change

Keeping records current is an ongoing legal responsibility.

What Is the PSC Register?

Most UK companies must maintain their own PSC register. This internal register records:

• Current PSCs
• Nature of their control
• Relevant dates
• Required legal statements

The company must also provide the required PSC information to Companies House through its filing obligations.

Companies Without PSCs

Not every company has a PSC. For example, four founders each own:

• 25%
• 25%
• 25%
• 25%

No one owns more than 25%. If none of the other PSC conditions apply, the company may legitimately have no PSC. In this situation, the company must still make the appropriate legal statement confirming that no registrable PSC has been identified.

Can a Company Be a PSC?

Sometimes. A legal entity such as another company may qualify as a Relevant Legal Entity (RLE) instead of an individual PSC. This commonly occurs within corporate group structures. For example: Holding Company Ltd owns 100% of Trading Company Ltd.

Depending on the ownership structure and legal requirements, the holding company may be recorded as the relevant legal entity while the individuals controlling the holding company may also need to be identified.

Why Accurate PSC Records Matter

Maintaining accurate PSC information is about more than legal compliance. It also supports:

• Faster Banking Processes: Banks often verify PSC information as part of Know Your Customer (KYC) and anti-money laundering checks.
• Investor Confidence: Investors expect ownership and control records to be clear and well maintained.
• Regulatory Compliance: Incorrect PSC information may lead to unnecessary delays, regulatory enquiries, or compliance issues.
• Better Corporate Governance: Clear ownership records reduce misunderstandings among founders and shareholders.

Common PSC Mistakes

• Assuming Every Director Is a PSC: Many directors are employees with no ownership or controlling rights. Directorship alone does not create PSC status.
• Forgetting to Report Ownership Changes: Bringing in investors or transferring shares often changes PSC status. These changes should be reflected promptly in company records.
• Confusing Shareholders with PSCs: A shareholder owning 5% of the company is usually not a PSC. Ownership percentage matters.
• Ignoring Indirect Control: Someone may qualify through voting agreements, trusts, or legal rights even without directly owning shares.

PSCs and International Founders

Many overseas entrepreneurs establish UK limited companies. The PSC rules apply regardless of nationality or country of residence. If a non-UK resident satisfies one of the PSC conditions, they must generally be recorded in the same way as a UK-based owner. This consistency helps make the UK's corporate system transparent while remaining accessible to global founders.
