What Is the Difference Between a Private and Public Limited Company?
The main difference is that a private limited company cannot offer its shares to the general public, while a public limited company can offer shares to public investors and may apply to list them on a stock exchange.
Private limited companies are identified by “Limited” or “Ltd,” while public limited companies use “public limited company” or “PLC.”
Both structures provide limited liability and exist as legal entities separate from their shareholders. However, public limited companies face higher capital requirements, stricter governance rules and more demanding reporting obligations.
A private limited company is a company incorporated at Companies House whose shares are held privately.
Its shareholders may include:
A private company cannot offer its shares to the public. Shares are instead issued or transferred privately, subject to company law, the articles of association and any shareholders’ agreement.
Most small and medium-sized UK companies use the private limited company structure.
A public limited company is an incorporated company that may offer shares to the public.
A PLC can potentially raise substantial amounts of capital from public investors. It may also apply to have its shares admitted to trading on a recognised stock exchange.
However, becoming a PLC does not automatically mean that the company is listed on a stock exchange. A public company can remain unlisted and have a relatively small group of shareholders.
A private limited company normally ends its registered name with:
A public limited company normally ends its name with:
The company name indicates its legal status. A business cannot simply add “PLC” to its name without satisfying the requirements for registration or re-registration as a public company.
Yes. Both private and public limited companies are separate legal entities.
Shareholders’ liability is generally limited to the amount unpaid on their shares. If their shares are fully paid, they are not normally required to contribute additional money solely because the company cannot pay its debts.
However, limited liability does not protect a shareholder or director from every risk. Personal liability may still arise from:
A private company can issue and transfer shares privately. It may raise investment from selected individuals, companies, venture-capital firms or other private investors.
However, it cannot offer its shares to the general public.
The issue or transfer of private-company shares may also be restricted by:
A private company can therefore raise equity investment without becoming a PLC, provided that it does not make an unlawful public offer.
A public limited company can offer shares to public investors, subject to applicable company, securities and financial-services rules.
Depending on the type and size of the offer, the company may need:
The ability to offer shares publicly is one of the main reasons a growing company may become a PLC.
No. A company’s status as a PLC and its stock-exchange listing are separate matters.
A company can be:
A PLC must separately satisfy the eligibility, admission and ongoing requirements of the relevant market before its shares can be publicly traded there.
A private limited company does not have the same statutory minimum share-capital requirement as a PLC. A private company may commonly be incorporated with a small amount of share capital, such as one ordinary share.
A public limited company must meet the authorised minimum. The nominal value of its allotted share capital must generally be at least:
The company cannot combine sterling and euro shares to meet the requirement. The required proportion of the allotted capital must also be paid up.
A newly incorporated PLC cannot conduct business or exercise borrowing powers until Companies House issues it with a trading certificate.
The company must apply using the required form and demonstrate that it satisfies the minimum share-capital requirements.
Trading or borrowing without the certificate is an offence and may expose the directors to penalties.
A private limited company does not need this type of trading certificate before beginning ordinary business activities.
A private limited company must have at least one director.
A public limited company must have at least two directors.
Every company must have at least one director who is a natural person, and directors must meet the applicable eligibility and identity-verification requirements.
Larger public companies will often have a more extensive board containing executive and independent non-executive directors.
A private limited company does not normally need to appoint a company secretary, although it can choose to have one.
A public limited company must have a company secretary. The secretary must have the necessary knowledge and experience, and applicable legal qualification requirements must be satisfied.
The company secretary may help manage:
Even when a company secretary is appointed, directors remain responsible for ensuring that the company complies with its legal obligations.
Both private and public companies must prepare accounts and file them with Companies House.
A private company normally has nine months after the end of its accounting reference period to file annual accounts.
A public company normally has six months.
Public companies are also subject to more demanding financial-reporting and audit requirements. They cannot generally use reporting exemptions reserved for qualifying small private companies.
A private limited company may qualify for an audit exemption if it meets the relevant legal conditions. Some private companies must still have an audit because of their size, activities, group structure or shareholder requests.
A public limited company is generally required to have its annual accounts audited.
Listed companies may face additional financial-reporting, audit and corporate-governance requirements imposed by securities regulators and the relevant market.
A public company is generally required to hold an annual general meeting.
Private companies are not normally required by the Companies Act to hold an AGM unless their articles or another binding agreement requires one.
A private company can often make shareholder decisions through written resolutions. Public companies face stricter meeting and resolution procedures.
Public companies are generally subject to greater disclosure and transparency requirements.
Depending on whether the company is listed, disclosures may include:
Private companies must also provide information to Companies House, but their reporting obligations are generally less extensive.
A private company may have one or many shareholders, but ownership remains privately held.
A PLC can also have a small number of shareholders, but it is legally capable of offering shares to the public. A listed PLC may have thousands or millions of shareholders.
In both structures, ownership percentages and rights depend on:
Directors manage the company, while shareholders exercise ownership rights through their shares.
In a small private company, the same person may be the sole director and shareholder, creating concentrated control.
In a large PLC, ownership may be spread among many investors. The board manages the company, while shareholders vote on matters such as electing directors and approving certain major decisions.
Shareholders with sufficient ownership or influence may also need to be disclosed under PSC or market-specific significant-shareholding rules.
PLC status may create an impression of scale, financial strength or maturity. However, it does not guarantee that the company is profitable, listed or financially secure.
The structure should be selected because it supports the company’s funding and ownership plans—not simply for the appearance associated with “PLC.”
Operating a public company can involve substantial legal, accounting, audit, regulatory and governance costs.
The main advantages include:
Potential disadvantages include:

Potential disadvantages include:
Yes. A private company can apply to re-register as a public limited company if it meets the legal requirements.
The process may involve:
Re-registering as a PLC does not automatically place the company’s shares on a stock exchange.
A public company may also be able to re-register as a private company.
This normally requires a special resolution and compliance with the relevant statutory process. Shareholders or creditors may have rights to object in certain circumstances.
Professional legal and accounting advice is recommended before changing company status.
A private limited company is normally more suitable for a small or medium-sized UK business.
It provides limited liability and a separate legal identity without the additional capital and governance requirements of a PLC.
A public limited company is more likely to suit an established business that:
A private limited company keeps its shares in private ownership and cannot offer them to the general public. It normally has lower capital requirements, simpler governance and fewer reporting obligations.
A public limited company can offer shares to public investors and may apply for a stock-exchange listing. It must satisfy minimum share-capital rules, have at least two directors, appoint a qualified company secretary and meet stricter reporting and governance standards.
For most owner-managed and growing UK businesses, a private limited company is usually sufficient. PLC status is generally more appropriate when a larger company needs access to public investment and can support the additional compliance costs.
