Advantages and Disadvantages of a Public Limited Company (PLC)

A public limited company (PLC) is a type of UK company that is legally permitted to offer its shares to the general public and, if it meets the requirements, apply for a listing on a recognised stock exchange such as the London Stock Exchange or AIM. For a full comparison of a PLC with a private limited company, see our guide to PLC vs Ltd differences. This article focuses specifically on the advantages and disadvantages of the PLC structure - and answers the common question of whether a PLC has limited liability.

Advantages of a public limited company

Raising capital from the public

The most significant advantage of a public limited company is its ability to raise capital by offering shares to the general public. A private limited company (Ltd) is prohibited from doing this. A PLC can run a public share offer or an initial public offering (IPO), opening the door to a far larger pool of investors than a private company can access through private placements alone.

Share liquidity and ability to list on a stock exchange

A PLC can list its shares on a recognised stock exchange, allowing them to be bought and sold freely in a secondary market. This liquidity benefits shareholders and makes shares more attractive as investments. Institutional investors such as pension funds often have mandates requiring them to invest only in publicly traded securities, so a listing widens the potential shareholder base considerably.

Prestige and credibility

PLC status signals that the company has met demanding capital and governance requirements and is accountable to public shareholders. In sectors where trust and scale matter - financial services, infrastructure, or large-scale professional services - this designation can strengthen relationships with corporate clients, regulators, and strategic partners.

Limited liability for shareholders

Like a private limited company, a PLC provides shareholders with limited liability. Shareholders are not personally responsible for the company's debts beyond any amount that remains unpaid on their shares. This protection is a feature of the limited company structure under the Companies Act 2006, not of whether the company is public or private.

Easier access to finance and institutional investment

A listed PLC often finds it easier to access debt finance as well as equity. Banks and bond markets tend to view large, publicly scrutinised businesses as lower credit risks - the transparency of regular public reporting reduces the information gap and can translate into better borrowing terms.

Disadvantages of a public limited company

Minimum share capital of GBP 50,000

Under the Companies Act 2006, a PLC must have an allotted share capital of at least GBP 50,000 in nominal value, with at least 25 per cent of that amount paid up before the company can trade or borrow. Companies House will not issue a trading certificate until this requirement is satisfied. This is a material barrier compared with a private limited company, which has no minimum share capital requirement and can begin trading immediately after incorporation.

Heavier regulation and reporting obligations

A PLC is subject to significantly more demanding legal and regulatory requirements than a Ltd company. It cannot use the simplified accounting exemptions available to small and micro private companies. It must prepare full statutory accounts, comply with the requirements of the Financial Conduct Authority if it is listed, and - for companies on a premium segment of a regulated market - adhere to the UK Corporate Governance Code. Directors of a PLC face more onerous duties and are subject to greater scrutiny from regulators, shareholders, and proxy advisers.

Greater public disclosure

A PLC must disclose substantially more information about its affairs than a Ltd company. Accounts, directors' remuneration, major shareholdings, and a range of other corporate matters are all in the public domain. While all limited companies must file some information at Companies House, the depth of disclosure required of a PLC - particularly a listed one - is considerably greater. This loss of confidentiality can be a competitive disadvantage in some industries.

Vulnerability to hostile takeover

Because a PLC's shares are freely tradeable on a public market, it is exposed to the risk of a hostile takeover bid. A buyer who accumulates a sufficient stake in the open market can mount a takeover offer without the board's agreement, subject to the City Code on Takeovers and Mergers. Private limited companies, whose shares cannot be sold to the public, are far better protected from this kind of unwanted approach.

Higher cost and administration

Running a PLC is materially more expensive than running a Ltd company. The requirements for a qualified company secretary, at least two directors, full statutory accounts, potential audit requirements, and - for listed companies - ongoing investor relations, regulatory filings, and compliance functions all add cost. These overheads are proportionate for a large business with access to public capital, but they make the PLC structure impractical for most smaller enterprises.

Does a PLC have limited liability?

Yes. A public limited company does have limited liability. Shareholders in a PLC are liable only for any amount that remains unpaid on their shares. If a shareholder has fully paid for their shares, they have no further personal liability for the company's debts or obligations, regardless of how large those debts may be.

The question "do public limited companies have limited liability" sometimes arises because the word "public" implies openness or exposure. But "limited" in the company name refers specifically to the liability of the shareholders - not to whether the company is publicly traded. Both PLCs and private limited companies carry this protection. It is the reason the Companies Act 2006 requires companies of both types to include "limited" within their registered name - whether as "limited", "ltd", "public limited company" or "plc": it signals to third parties dealing with the company that shareholder liability is capped.

Is a PLC right for a new business?

In almost all cases, no. The PLC structure is not suited to a newly formed business. The GBP 50,000 minimum share capital, the requirement for at least two directors and a qualified company secretary, the trading certificate process, and the heavy ongoing regulatory burden all make it an impractical starting point for most founders.

The scale of the gap in practice is striking. Of the more than 6 million companies on the Companies House register, fewer than 5,000 are public limited companies - less than 0.1 per cent. The vast majority of newly incorporated UK companies are private limited companies (Ltd). As our PLC vs Ltd guide explains, businesses typically reach PLC status by re-registering from a Ltd structure when they are preparing for a stock market listing or have grown to the point where access to public capital markets justifies the additional cost and compliance burden.

If you are a business development professional, recruiter, lender, or professional services provider looking to connect with newly formed UK companies, the newly incorporated Ltd is the market. New PLC registrations are rare and tend to accompany major corporate events rather than representing new business formation in the ordinary sense.

Does a PLC need to be listed on the stock market?

No. A PLC is simply a company that has the legal right to offer shares to the public and meets the minimum capital requirements (£50,000 paid-up share capital). It does not need to actually list on any stock exchange. Many PLCs are privately-held with shares owned by a small group of institutional investors. Listing is a separate decision and process that follows incorporation as a PLC.

Are there any UK PLCs that are newly incorporated each year?

Very few. The vast majority of new UK company registrations are private limited companies. Of the approximately 780,000 new companies registered in the UK each year, only a small fraction incorporate as PLCs. Most companies that become PLCs do so by converting from a private limited company as they grow and seek access to public markets.
