What Is a Public limited Company?

A PLC or public limited company in the UK is a type of limited company that is legally distinct from its owners. It can offer its shares to the public and trade them on a stock exchange. This structure enables PLCs to raise capital from a broader base of investors, distinguishing them from private limited companies. The focus on public investment and the ability to issue shares to the general public are central features of a PLC.

Examples of Public Limited Companies

PLCs vary in size and operate across different sectors, demonstrating the versatility and appeal of this business structure.

Here are some prominent examples:

Key Features of Public Limited Company

PLCs are characterized by defining features that set them apart from other business entities. These features dictate their operational framework and shape their interactions with investors and the market. Here are some key characteristics:

  • Public Share Trading: PLCs are unique in that they can sell shares to the general public on the stock exchange. This ability to raise capital from public investors is a cornerstone of their structure.

  • Legal Requirements: A PLC must adhere to strict legal requirements, including having a minimum issued share capital of £50,000 with at least 25% paid before they start trading.

  • Corporate Governance: PLCs are subject to strict governance standards, ensuring transparency and accountability in their operations. This includes detailed financial reporting and regular disclosures to shareholders.

  • Shareholder Rights and Board Structure: Shareholders in a PLC have the right to vote on important company decisions. PLCs are also required to have a board of directors and, in many cases, a company secretary.

  • Board of Directors: Typically, the shareholders elect a board of directors to manage them. The board is responsible for the company’s overall management and strategic direction.

  • Limited Liability: Shareholders in a PLC are subject to limited liability. This means their personal assets are protected, and their financial responsibility is limited to the amount they have invested in shares.

Public Limited Company Advantages and Disadvantages

Before starting or choosing a business structure, it’s essential to understand the benefits and drawbacks of every business structure. This is also true when you want to learn about a UK public limited company (PLC).

The unique attributes of PLCs offer significant benefits but also have certain drawbacks. Let’s delve into the pros and cons of PLC:

Advantages of PLC

  • Access to Capital: PLCs can raise substantial funds by selling shares to the public on the stock exchange, providing a significant financial boost for growth and expansion.

  • Limited Liability: Shareholders enjoy limited liability, which means their personal assets are protected; their financial risk is limited to their investment in the company.

  • Market Prestige: Being listed on a stock exchange enhances a company’s prestige and credibility, benefiting business relationships and public perception.

  • Transferability of Shares: Shares of a PLC can be easily bought and sold, providing liquidity for shareholders and facilitating investment and divestment.

  • Growth and Expansion Opportunities: The capital raised can fuel research, development, and expansion strategies, driving the company’s growth.

While all of these things may make becoming a PLC seem like a good idea, it does come with some problems. Here are some of the drawbacks that PLCs have:

Disadvantages of PLC

  • Complex Regulation and Compliance: PLCs face stringent regulatory requirements, including detailed financial reporting and disclosure, which can be complex and costly.

  • Vulnerability to Market Fluctuations: PLCs are subject to market conditions and investor sentiment, which can lead to volatility in share prices and corporate stability.

  • Loss of Control: Original owners may lose a degree of control over the company as shareholders have voting rights on significant company matters.

  • Number of Directors: To run a public limited company in the UK, you will need a minimum of two directors. This is one of the critical disadvantages business owners may face.

  • Increased Public Attention: Being a PLC means being under constant scrutiny by shareholders, analysts, and the public, which can pressure the company’s performance and strategy.

  • Risk of Takeover: Public listing can increase the risk of hostile takeovers if majority control is lost.

  • Accounting Complication: A public limited company cannot qualify as a small or medium-sized company for accounting purposes. So this type of limited company cannot benefit from the exemptions, such as audit exemptions, that such a classification would grant.

    Understanding these advantages and disadvantages is crucial for any business considering transitioning to a public limited company in the UK or investors contemplating involvement in such entities.

When Should Businesses Become Public Limited Companies?

A crucial question arises after examining the advantages and disadvantages of public limited companies in the UK: When is the right time for a business to transition into a PLC?

A thorough assessment of the company’s position, goals, and readiness to embrace public entity challenges and opportunities should inform this crucial decision. Here are vital considerations that signal when a business might be ready to become a public limited company:

  • Maturity and Stability: Companies must have a track record of profitability and stability. A strong foundation and consistent performance are crucial to attracting investors.

  • Need for Capital: Going public can be effective if a business requires significant capital for expansion or large-scale projects that cannot be funded through private investments or loans.

  • Desire for Liquidity: Owners looking to convert their ownership into liquid assets might find going public beneficial, as it provides a market for selling their shares.

  • Growth Ambitions: Companies aiming for rapid growth or expansion, including entering new markets or developing new products, may benefit from the financial injection that a public offering can provide.

  • Market Conditions: Favourable market conditions, such as a strong economy or a bullish stock market, can make it an opportune time to go public.

  • Increased Credibility: Businesses seeking to enhance their credibility and public profile might choose to become PLCs to leverage the prestige of being a publicly listed company.

  • Ready for Scrutiny and Regulation: The decision should come –
    when the business is prepared to comply with the stringent regulatory requirements
    handle the increased scrutiny from shareholders and the public.

    The transition to a public limited company is a significant strategic move. Timely and careful planning, business assessment, and goal assessment are needed here.

Ownership and Management of a Public Limited Company in the UK

The ownership and management structure of a public limited company (PLC) in the UK is a critical aspect that defines its operational dynamics and accountability. Let’s start with the first question in your mind that may be arising now :

Who Owns Public Limited Company?

Unlike private limited companies, there is typically no single ‘owner’ of a PLC. Even the largest shareholder rarely owns a majority of the shares. This dispersed ownership structure differentiates PLCs and influences their governance and operations.

  • The owners of a public limited company are its shareholders. Since PLCs can sell their shares on the stock exchange, they may have a wide range of shareholders, including members of the general public. Individuals, institutional investors, or other businesses can purchase shares when a PLC issues them.

  • The ownership of a PLC can frequently change as shares are bought and sold on the stock market. The extent of ownership is proportional to the number of shares held in a public limited company.

  • The nature of PLCs means that no single entity typically controls the entire company. Major shareholders may have significant influence, but the dispersed nature of ownership ensures a level of democracy in how the company is run.

  • Shareholders exercise their ownership rights through voting on key company matters, typically at the annual general meeting (AGM) or extraordinary general meetings (EGMs). This includes electing the board of directors, approving major decisions like mergers or acquisitions, and influencing company policy.

Who Manages the Public Limited Company?

While shareholders own the company, a board of directors typically handles day-to-day management and operational decisions. These directors are responsible for the company’s strategic direction and day-to-day management, making decisions in its and its shareholders’ best interests.

  • In addition to the board, a PLC must have a company secretary responsible for overseeing regulatory compliance and corporate governance matters. The company secretary ensures that the company adheres to legal requirements and best practices in corporate governance.

  • The shareholders elect this board, which oversees the company’s strategy and governance. This separation of ownership and management is a crucial feature of PLCs, allowing professional company management while providing owners with a mechanism to influence significant decisions through their voting rights.

Understanding who owns a PLC provides insight into how these companies operate and are controlled. UK PLC ownership and management must balance shareholder interests, regulatory compliance, and corporate governance to maintain investor confidence and long-term success.

Accounting Requirements and Responsibilities in a Public Limited Company

Following our exploration of the ownership and management of a public limited company in the UK, it is equally important to learn about the accounting requirements and responsibilities these entities must adhere to.

Here’s an overview of the key accounting requirements and responsibilities for PLCs:

  • Financial Reporting Standards: PLCs must prepare financial statements that comply with the UK Generally Accepted Accounting Practise (UK GAAP) or International Financial Reporting Standards (IFRS). This ensures consistency, transparency, and comparability of financial information.

  • Annual Accounts and Reports: PLCs must produce annual accounts and reports, including a balance sheet, a profit and loss account, a cash flow statement, and a director’s report. These documents provide a complete overview of the company’s financial performance and position.

  • Statutory Audit: Public limited companies are subject to mandatory audits. An independent auditor must review the annual accounts to verify their accuracy and compliance with the relevant accounting standards and legal requirements.

  • Public Disclosure: Once audited, the financial statements must be filed with Companies House and made available to shareholders and the public. This ensures transparency and allows stakeholders to assess the company’s financial health and performance.

  • Regular Financial Reporting: Besides annual reports, PLCs may be required to produce interim financial statements, updating their financial status throughout the year. This is especially important for companies listed on the stock exchange.

  • Tax Compliance: A Public Limited Company in the UK must adhere to tax laws, including calculating and paying corporation tax. They are also responsible for submitting accurate tax returns on time.

  • Corporate Governance in Reporting: The company’s board ensures the financial reporting process is robust and transparent. This includes overseeing the auditor’s work and ensuring that the financial reports provide an accurate and fair view of the company’s finances.

  • Shareholder Communication: PLCs must keep their shareholders informed about their financial status. This is typically done through the annual general meeting (AGM), where the annual accounts are presented and discussed.

    UK public limited companies must have strict financial discipline, transparency, and accountability in their accounting. The company’s long-term success, compliance, and investor confidence depend on these requirements.


Q1: Can a public limited company change its structure to that of a private limited company?
