PSC Meaning: What Is a Person with Significant Control in UK Company Law?

If you’re thinking about setting up a company in the UK - or maybe you’re already running one - you’ve probably come across the term “PSC” in forms or guidance from Companies House. But what exactly is a PSC, and why does it matter for your business?

Don’t worry if you’re a bit unsure. Understanding PSC meaning is a crucial step in staying compliant with UK company law. Whether you’re just starting your venture or looking to make changes to your company’s ownership, knowing what a Person with Significant Control (PSC) actually is will help you get your legal foundations right - and avoid trouble down the line.

In this guide, we’ll break down the concept of a PSC, explain why it matters, who qualifies, and what you need to do as a business owner to comply. Let’s demystify PSC meaning and help you feel confident about your obligations.

What Does PSC Mean in UK Company Law?

PSC stands for Person with Significant Control. In simple terms, this is someone who owns or controls your UK company. The PSC regime was introduced through the Small Business, Enterprise and Employment Act 2015 to increase transparency over who really holds power within UK companies.

The law requires UK companies and LLPs (Limited Liability Partnerships) to:

• Identify any people with significant control over the company
• Maintain a PSC register (an up-to-date list of PSCs)
• Disclose this information to Companies House

This means PSCs are a major part of your company’s official public record. If you’re running a business, understanding PSC meaning isn’t just admin - it’s a legal requirement.

Why Does Identifying PSCs Matter for My Business?

You might be wondering why PSCs are so important. Here’s why the rules exist - and why you need to care as a company director or owner:

• Transparency: These laws help ensure it’s clear who really owns and controls companies operating in the UK. This is designed to prevent things like money laundering, tax evasion, or using “shell companies” for shady business.
• Legal Compliance: You are required by law to keep an accurate PSC register and notify Companies House when changes occur. Failure to do so can lead to criminal penalties and fines.
• Building Trust: Investors, banks, and stakeholders may review your company’s PSC records to understand who’s involved and how control is exercised.

Running a UK business comes with a few non-negotiables - maintaining your PSC records is one of them. Just as you wouldn’t skip getting the right contracts or following GDPR, you shouldn’t neglect this step, either.

What Counts as ‘Significant Control’? When Is Someone a PSC?

The law defines a PSC quite precisely. A PSC is anyone who meets one or more of these conditions:

• Directly or indirectly holds more than 25% of the shares in the company
• Directly or indirectly holds more than 25% of the voting rights in the company
• Has the right to appoint or remove the majority of the board of directors
• Otherwise has the right to exercise, or actually exercises, significant influence or control over the company
• Has significant influence or control over a trust or firm that meets any of the above conditions

Often, your company’s shareholders and directors will be obvious PSCs. But sometimes, the situation can be more complicated - for example, if ownership is split across groups, held in trusts, or you have overseas owners.

Common PSC Scenarios

• A founder owns 60% of shares - they are a PSC
• Two co-founders each hold 30% - both must be listed as PSCs
• 20 people hold 5% each - if no one has over 25%, then you may not have a PSC under the shareholding test (but other influence criteria might still apply)
• A corporate entity (e.g. holding company) owns 30% - the controlling persons in that company may be PSCs via indirect ownership

Not sure who your PSCs are? This is where it’s wise to talk to a legal expert or accountant - getting it wrong can lead to compliance headaches and fines. Our dedicated guide to PSCs in UK companies can help you dig deeper into indirect ownership and complex group structures.

What Does the PSC Register Include?

Your company’s PSC register must be kept up-to-date and available for inspection at your registered office. So, what information are you required to record?

• Name
• Date of birth
• Nationality
• Service address and usual residential address
• Date they became a PSC
• Which of the significant control criteria they meet (and a description of the relevant control/ownership)
• Date you entered them into the register

This information must be submitted to Companies House when you incorporate and updated whenever a change occurs (for example, if someone sells shares and drops below the 25% threshold).

How Do I Identify and Record Our PSCs?

Companies have a duty to take reasonable steps to identify PSCs. So, what does that actually mean in practice?

• Review shareholdings and voting rights: Check the company’s register of members.
• Examine constitutional documents: See who has the power to appoint or remove directors.
• Ask questions: If it’s not clear, ask shareholders or related companies if they meet the PSC criteria.
• Get professional help if things are complex: If you have overseas shareholders, trusts, multiple holding companies or special arrangements, it’s smart to seek advice. You may need to “look through” several layers to find the real PSCs.

Once you know who your PSCs are, you must:

• Enter accurate records in your PSC register
• File PSC details with Companies House
• Update both your register and Companies House whenever something changes

What Happens If I Don’t Comply with PSC Rules?

The consequences of ignoring the PSC regime aren’t something you want to risk. Under UK law, company officers can face:

• Fines and criminal prosecution for failing to keep a PSC register
• Penalties for not providing up-to-date or accurate information to Companies House
• Reputational damage - your company's public record may show as “non-compliant”

Remember - as a director, you’re legally responsible for making sure your company follows the PSC regime. Ignorance isn’t a defence. If you’re having trouble tracking down the right information (for instance, if a shareholder won’t respond), you do have “warning and restrictions” powers - another reason getting legal help early can really pay off.

How Does PSC Fit into the Bigger Picture of Starting a UK Company?

Getting your PSC register right is part of a wider set of compliance duties when setting up a UK company. It sits alongside key legal steps such as:

• Choosing the best company structure
• Registering your business with Companies House
• Drafting Articles of Association and Shareholders’ Agreements
• Complying with UK company law, tax, and reporting requirements
• Following data protection and privacy regulations

All of these steps are crucial to being protected from day one. For a comprehensive walkthrough, see our step-by-step guide to incorporating your UK business.

FAQs About PSCs and UK Company Law

Do All Companies Need a PSC Register?

Yes, almost all UK companies and LLPs must maintain a PSC register. The only exceptions are some publicly listed companies, which are subject to different (but equivalent) transparency requirements.

What if My Company Doesn’t Have a PSC?

You must still keep a PSC register, even if you state that there are currently no people with significant control. This is still a legal requirement and the register can’t be left blank.

Can a Company Be a PSC?

Usually, a PSC has to be an individual. However, if your company is wholly owned or controlled by another legal entity that is itself transparent (for example, another company on the UK public register), you may list that entity as a “Relevant Legal Entity” (RLE). Don’t worry - this can get tricky, so it’s best to get advice in this scenario.

How Do I Update My PSC Register?

Whenever there’s a change (for example, someone’s shareholding moves from 30% to below 25%), you must update both your internal PSC register and notify Companies House within 14 days. Keep this up to date - it’s one thing that’s easy to slip through the cracks.
