What Is a Share Certificate and Does Every UK Company Need One?

A share certificate is a document issued by a company to a shareholder as evidence of the shares registered in that person's name. It normally identifies the shareholder, the number and class of shares held, and other details about those shares. For UK company owners, however, one important distinction is often missed: A share certificate is evidence of share ownership, but the certificate itself is not what creates the shareholder's legal ownership.

The company's register of members is central to determining who is a member of the company. HMRC explains that a person must be entered in the register of members to be a member under UK company law, while possession of a share certificate is only prima facie evidence of ownership.

So, does every UK company need a share certificate? For a company limited by shares, shareholders will generally need certificates under the company's articles and the Companies Act framework. The model articles for private companies limited by shares expressly require the company to issue each shareholder, free of charge, with one or more certificates for their shares. But there are important exceptions and practical details to understand.

A share certificate is a formal document issued by a company confirming the shares registered in a shareholder's name. A typical certificate may state:

The company's name
The shareholder's name
The number of shares held
The class of shares
The nominal value of the shares
Whether the shares are fully paid
Any identifying numbers assigned to the shares
Details required by the company's constitution or applicable law

Under the model articles for a private company limited by shares, a certificate must specify the number and class of shares, their nominal value, whether they are fully paid and any distinguishing numbers assigned to them. A certificate cannot cover shares belonging to more than one class. For example, if Jane owns 1,000 A Ordinary Shares and 500 B Ordinary Shares, the company may issue separate certificates for the two classes rather than combining them into a single certificate.

Yes, but with an important qualification. A share certificate is strong evidence of the shares recorded in the shareholder's name. However, it is not the ultimate source of membership. HMRC explains that possession of a share certificate is prima facie evidence of ownership but does not, by itself, confirm ownership. To be a member of the company, the person must be entered in the company's register of members. This distinction matters when dealing with:

New share issues
Transfers of shares
Lost certificates
Company acquisitions
Shareholder disputes
Estate administration
Due diligence by investors

A company should therefore keep its register of members and share certificates consistent.

No. These documents serve completely different purposes.

Certificate of incorporation

The certificate of incorporation confirms that the company itself legally exists. Companies House states that it is conclusive evidence that the company has been registered under the Companies Act 2006. It normally includes information such as:

Company name
Company number
Date of incorporation
Whether the company is private or public
Whether it is limited by shares, limited by guarantee or unlimited
The jurisdiction of its registered office

A share certificate relates to shares in the company, not the existence of the company. A useful way to remember the distinction is: Certificate of incorporation = proof the company exists. Share certificate = evidence relating to a shareholder's registered shares. A company can therefore have one certificate of incorporation but multiple share certificates issued to different shareholders.

The answer depends partly on the type of company and its constitutional arrangements. A company limited by shares has shareholders and share capital. GOV.UK confirms that such a company must have at least one shareholder and can issue different classes of shares.

For a private company using the model articles, Article 24 requires the company to issue each shareholder, free of charge, with one or more certificates in respect of the shares that shareholder holds. Therefore, for the typical UK private limited company limited by shares, share certificates are an important part of the company's corporate records.

However, not every company has shares at all. For example, a company limited by guarantee has guarantors rather than shareholders and shares. Consequently, there is no ordinary share certificate to issue in the same way. The first question should therefore be:

Is this a company limited by shares?

If yes, share certificates are normally relevant. If it is a company limited by guarantee, the position is different.

Share certificates commonly arise when shares are:

Issued or allotted to a shareholder
Transferred from one shareholder to another
Replaced because a certificate is lost, stolen or damaged
Otherwise required under the company's articles or applicable company law

The Companies Act framework generally requires companies to complete and have ready for delivery certificates following an allotment or a properly registered transfer within the applicable statutory period, subject to the relevant exceptions and constitutional provisions.

The model articles also require certificates to be issued to shareholders and provide a mechanism for replacement certificates. This means that issuing a certificate should be part of the company's normal share administration rather than something founders remember only when an investor asks for one.

What Happens When a Company Issues New Shares?

Suppose a UK startup has one founder holding 1,000 ordinary shares, The company later issues another 1,000 shares to an investor. After the allotment:

The founder holds 1,000 shares
The investor holds 1,000 shares
Total issued shares become 2,000

The company should update its statutory records and issue the investor an appropriate share certificate. It must also deal with the Companies House filing requirements. GOV.UK states that a company must tell Companies House within one month when it issues more shares.

The filing includes a statement of capital showing information such as the total number and value of shares and the rights attached to each share class. This illustrates an important point: a share certificate is only one part of the company's share records.

What Happens When Shares Are Transferred?

A share transfer is different from issuing new shares. Suppose Founder A owns 1,000 shares and transfers 200 to Founder B. The company's total issued share capital does not automatically increase. Instead, ownership of the relevant shares changes. The company should update its register of members and deal with the existing share certificate appropriately, depending on the company's procedures and the terms of the transfer.

The transfer may also have tax implications. For example, Stamp Duty can apply to certain purchases of shares. HMRC provides specific rules for completing stock transfer forms, including circumstances involving consideration of £1,000 or less and transfers for which no consideration is given. For founders, the lesson is straightforward: do not treat a share transfer as simply changing a name on a certificate. The underlying company records must also be updated.

The exact format can vary, but a properly prepared certificate should contain the information necessary to identify the shares and the holder. Under the model articles, this includes:

The number of shares covered
The class of shares
The nominal value of the shares
Confirmation that the shares are fully paid
Any distinguishing numbers assigned to the shares

The certificate must also be properly executed in accordance with the applicable company requirements.

What about alphabet shares?

If a company has multiple classes, the class needs to be clearly identified. For example:

1,000 A Ordinary Shares
500 B Ordinary Shares
200 Preference Shares

The certificate should clearly identify which class the shareholder owns. This is particularly important because different classes can carry different voting, dividend and capital rights. Companies House requires companies to provide information about the rights attached to different share classes when relevant changes are filed.

Can a Shareholder Have More Than One Certificate?

Yes. The model articles allow a company to issue one or more certificates in respect of a shareholder's shares. Separate certificates can be useful where a shareholder owns different classes of shares. For example:

Certificate 1: 5,000 A Ordinary Shares

Certificate 2: 2,000 B Ordinary Shares

This can make the company's records easier to understand, particularly where the rights attached to the classes differ.

Losing a share certificate does not normally mean the shareholder loses the shares. The model articles specifically provide for replacement certificates where an existing certificate is damaged, defaced, lost, stolen or destroyed. The company can require evidence, an indemnity and, where appropriate, payment of a reasonable fee for the replacement. A sensible company should therefore keep a record of:

Certificate numbers
Dates of issue
Shareholder names
Number and class of shares
Cancellations
Replacements
Transfers

The exact record-keeping system can vary, but the company's records should make it possible to reconstruct the ownership history.

A missing certificate does not necessarily mean that a transfer is impossible. The company must establish the shareholder's entitlement and follow the applicable transfer procedure. The register of members remains central to membership and ownership records.

However, a missing certificate can create practical complications, especially where a buyer, solicitor, investor or purchaser expects documentary evidence of title. The company may therefore require a lost-certificate declaration, indemnity or other evidence before issuing a replacement or registering a transfer. The company's articles and any shareholder agreement should be checked before proceeding.

Generally, no. A share certificate is normally an internal company document issued to the shareholder. It is not the same thing as information displayed on the Companies House public register.

Companies House does hold public information about a company's share capital and shareholders in various filings and records. However, Companies House confirms that certificates ordered from its service do not provide shareholder, shareholding or statement-of-capital information in the same way as a company-issued share certificate. This distinction can matter for overseas founders who may assume that Companies House automatically stores a digital copy of every shareholder's certificate. It does not.

These documents and records have different functions.

Record	Main purpose
Certificate of incorporation	Confirms the company legally exists
Share certificate	Evidence of shares registered in a shareholder's name
Register of members	Company's formal record of its members
Statement of capital	Records company share capital and class information
Confirmation statement	Periodic Companies House filing confirming key company information
Stock transfer form	Documents a transfer of shares between parties

A well-run company should keep these records consistent. For example, if the register of members says a shareholder owns 5,000 shares but an old certificate says 3,000, the company should investigate the discrepancy rather than simply relying on whichever document is more convenient.

What Should New Founders Do?

For a newly incorporated UK company limited by shares, founders should create a simple corporate records process from day one. At minimum, keep track of:

The original shareholders
Number and class of shares issued
Nominal value
Amount paid or unpaid
Share certificates
Certificate numbers
The register of members
Share allotments
Share transfers
Changes to share classes
Relevant Companies House filings

This becomes increasingly important as the company grows. An early-stage founder may have only one shareholder and 100 ordinary shares. Five years later, the company might have founders, angel investors, employees and institutional investors holding several classes of shares. If the records were poorly maintained from the beginning, reconstructing the company's ownership history can become unnecessarily difficult.

Share certificates often become particularly important during due diligence. Imagine a company is being acquired for £2 million. The buyer's legal advisers will want to establish:

Who actually owns the shares?
How many shares exist?
What classes exist?
Are the shares fully paid?
Are there restrictions on transfers?
Are there options or other rights affecting the shares?
Are the company's statutory records consistent?

Share certificates can form part of the documentary evidence supporting the company's ownership records. For this reason, a company that has ignored its share documentation for years can create avoidable problems when it eventually seeks investment or sells the business.

The practical treatment of electronic records depends on the company's constitution, the applicable legal requirements and how the certificate is executed. The key issue is not whether a certificate looks traditional or modern. It is whether it has been validly issued and executed in accordance with the company's legal and constitutional requirements.

Companies should therefore avoid assuming that simply creating a PDF with the words "share certificate" automatically satisfies every requirement. Where a company uses digital corporate records, it is sensible to ensure the process has been reviewed against its articles and applicable company law.

Frequently Asked Questions

For a typical private company limited by shares using the model articles, the articles require the company to issue shareholders with certificates for their shares. The precise position can depend on the company's articles and applicable statutory provisions.

It is evidence of ownership, but it is not the sole determinant of membership. The company's register of members is central to establishing who is a member of the company.

Does every UK company have shareholders?

No. Companies limited by guarantee have guarantors rather than shareholders. A company limited by shares, on the other hand, must have at least one shareholder.

No. Share certificates are generally issued by the company to its shareholders. Companies House maintains the company's public record and provides certain official certificates relating to the company itself, such as the certificate of incorporation.

A company can maintain modern digital corporate records, but whether a particular electronic certificate is valid depends on the company's articles, execution requirements and applicable law. It should not simply be assumed that any PDF automatically qualifies.

Losing the document does not normally mean losing the shares. The company's records can establish the shareholder's position, and the model articles provide for replacement certificates subject to conditions the directors may impose.

Not necessarily, but a missing certificate can complicate the transfer process. The company will need to establish the relevant entitlement and comply with its articles and share-transfer procedures.

It normally shows the nominal value of the shares, not necessarily their current market value. A £1 nominal-value share could be worth substantially more, or less in the real market.

Yes, if it is a company limited by shares, the shareholder should ensure the company's share records and certificate are properly maintained. A single shareholder does not make corporate records unnecessary.

Conclusion

A share certificate is a straightforward document with an important role in UK company administration. It provides evidence of the shares registered in a shareholder's name and can become particularly valuable during share transfers, investment rounds, due diligence and business sales. But it is equally important not to misunderstand what the certificate does. The certificate is evidence; the company's register of members is fundamental to membership.

For a typical private limited company using the model articles, shareholders should receive share certificates, while the company should also maintain accurate records of its members, share capital, allotments and transfers. For founders, the best approach is to treat share certificates as part of a wider corporate record-keeping system rather than as a standalone piece of paperwork. This becomes even more important when a company has multiple shareholders or different share classes.

Whether you are forming a company in the UK for a local business or managing one remotely as a global founder, keeping the ownership records accurate from the beginning can save significant time and legal expense later. A UK company formation and management platform such as IncorpUK can form part of that wider administrative infrastructure, while more complex ownership arrangements may require professional legal or accounting advice.
