How many shares should a UK company issue when it is formed?
There is no fixed number of shares that every UK limited company must issue when it is formed. A private company limited by shares must have at least one shareholder, but the appropriate number of shares depends on its ownership arrangements and future plans.
A company with one owner may issue just one ordinary share. However, many companies issue 100 ordinary shares because this makes ownership percentages and future share transfers easier to calculate.
A company limited by shares can usually be formed with one shareholder holding one ordinary share.
For example:
The shareholder may also be the company’s sole director. GOV.UK guidance
Both structures can give one person complete ownership, but they offer different levels of flexibility.
One ordinary share may be suitable when:
If the owner later wants to give someone 20% of the company, the company would need to issue more shares or subdivide the existing share.
One hundred ordinary shares may be more practical when:
With 100 identical shares, each share represents 1% of the company.
For example, a person holding 60 shares owns 60%, while someone holding 40 shares owns 40%.
A sole owner could issue either one ordinary share or 100 ordinary shares.
One share is sufficient if the owner wants a very simple structure. One hundred shares may provide more flexibility if the owner expects to sell part of the company or introduce a business partner later.
For example, an owner with 100 shares could transfer 30 shares to a new partner. The original owner would retain 70%, and the new partner would own 30%.
Two founders could issue 100 shares and divide them according to their agreed ownership percentages.
Common arrangements include:
The division should reflect the founders’ agreement rather than automatically being equal.
A 50/50 structure can create a deadlock if the shareholders disagree. A shareholders’ agreement can explain how important decisions and disputes will be handled.
A startup expecting several founders, investors or employee shareholders may issue 1,000, 10,000 or another convenient number of shares.
A larger number allows ownership to be divided into smaller percentages.
For example, a startup could issue 10,000 shares as follows:
Issuing more shares does not automatically make a company more valuable. What matters is the ownership percentage and the rights attached to each share.
Each share must have a nominal value. Common choices include:
For example, 100 shares with a nominal value of £1 create total nominal share capital of £100.
Alternatively, 100 shares with a nominal value of £0.01 create total nominal share capital of £1.
The nominal value is not the market value of the company. A company with nominal share capital of £1 or £100 could eventually be worth significantly more.
Shareholders may be required to pay any unpaid nominal value if the company is wound up. Companies should therefore avoid creating unnecessarily high nominal share capital.
For a straightforward small company, shares are often issued as fully paid. This means the shareholder pays the entire nominal value.
If 100 shares are issued at £1 each and fully paid, the shareholder pays £100 to the company.
Shares can also be partly paid or unpaid, but the outstanding amount remains payable and must be recorded. A modest number of fully paid shares is usually easier to administer.
Yes. A UK company can issue additional shares after incorporation, subject to its articles of association, existing shareholder rights and company-law requirements.
Issuing new shares may dilute the ownership percentages of existing shareholders.
For example, if one shareholder owns all 100 existing shares and the company issues another 100 shares to an investor, the original shareholder’s ownership falls from 100% to 50%.

No. The number of shares determines how ownership is divided, but it does not establish the market value of the company.
One share, 100 shares or 10,000 shares could all represent complete ownership of the same business.
A company’s value depends on factors such as:
When a company limited by shares is formed, its incorporation documents must include a statement of capital and initial shareholdings.

The rights attached to each class should explain voting, dividend, capital and redemption rights. GOV.UK incorporation guidance
Before choosing the number of shares, consider:
For most small companies, one class of ordinary shares is sufficient. More complex arrangements may require tailored articles of association and professional advice.
Common share-structure mistakes include:
Yes. A sole shareholder can hold one ordinary share representing 100% of the company.
There is no legally required standard. However, 100 shares is a common and convenient choice because each identical share can represent 1% of the company.
Yes. A company may issue 1,000 or more shares if that structure suits its ownership and investment plans.
Yes. A company can issue shares with a nominal value of £0.01.
No. A company can create different share classes, but the rights attached to each class must be clearly defined.
Yes. Subject to the required procedures, a company may issue, subdivide, consolidate, repurchase or cancel shares.
A UK limited company can be formed with one shareholder holding one ordinary share. For many small businesses, however, issuing 100 ordinary shares provides a convenient and flexible structure because ownership percentages are easy to calculate.
Companies expecting several founders, investors or employee shareholders may prefer 1,000 or 10,000 shares with a low nominal value.
The best number of shares is the one that accurately reflects the intended ownership, provides suitable flexibility and avoids unnecessarily high nominal share capital.
