What is the best share structure for a UK limited company?
For many small UK limited companies, the best share structure is 100 ordinary shares with a nominal value of £1 each. This structure is simple to understand and makes it easy to divide ownership using percentages.
However, the right structure depends on the number of shareholders, their ownership percentages, voting rights, dividend arrangements and future investment plans.
A company’s share structure sets out:
A UK company limited by shares must have at least one shareholder. The shareholder may also be a director, and there is no statutory maximum number of shareholders. GOV.UK shareholder guidance
Issuing 100 ordinary shares is often a practical choice because each share represents 1% of the company.
For example:
This structure makes ownership percentages easy to calculate and allows smaller portions of the company to be transferred or sold later.
The company could use a nominal value of £1, £0.10 or £0.01 per share. Nominal share capital does not represent the market value of the business.
A sole owner can establish a company with:
In both cases, the shareholder owns 100% of the company.
One share is the simplest option. However, 100 shares may offer greater flexibility if the owner plans to introduce a business partner, investor or employee shareholder later.
For example, transferring 20 out of 100 shares would give the new shareholder 20% ownership. With only one issued share, the company would first need to issue or subdivide shares to create the desired percentage.
Two shareholders should choose a structure that reflects their agreed ownership and responsibilities.
Common arrangements include:
A 50/50 structure may appear fair, but it can create a deadlock if the shareholders disagree. Neither shareholder has enough voting power to make a majority decision alone.
If equal ownership is selected, the company should consider having a shareholders’ agreement that explains how disputes and deadlocks will be resolved.
Where a company has several founders, issuing 100, 1,000 or 10,000 ordinary shares can provide flexibility.
For example, a company with three founders might issue 1,000 shares:
The agreed allocation should consider each founder’s:
The founders should also agree what happens to a person’s shares if they leave the company.
A family company may use one class of ordinary shares if every shareholder is intended to have the same rights.
Some family companies use alphabet shares, such as A, B and C ordinary shares, to provide different dividend or voting rights. However, these arrangements must be properly drafted and may have tax implications.
Different share classes should not be created solely as an informal way to distribute profits differently. Professional legal and tax advice is advisable before using alphabet shares.
A company planning to attract investors may need a more flexible structure.
The founders might own ordinary shares, while investors receive a separate class carrying specific rights. These could include:
Investor share structures can become complex. The articles of association, investment agreement and shareholders’ agreement should clearly explain the rights attached to each class.
Most small UK companies begin with one class of ordinary shares. According to GOV.UK, ordinary shares will usually provide one vote per share and entitlement to dividends, although the exact rights depend on the company’s articles. GOV.UK shareholder guidance
A single class is generally suitable when:
Different classes may be appropriate when:
The rights attached to each class must be clearly recorded in the company’s constitutional documents and statement of capital.
The nominal value of a share can be set at a low amount, such as £1, £0.10 or £0.01.
For example:
The nominal value is not the commercial value of the share or the company. It is the minimum capital attributed to that share.
A shareholder may be responsible for paying any unpaid nominal value if the company closes. For this reason, companies should avoid creating unnecessarily high nominal share capital.
Shares may be fully paid, partly paid or unpaid, depending on the arrangement.
For most straightforward small-company formations, issuing a modest number of fully paid ordinary shares is easier to administer. Any unpaid amount must be recorded and may remain payable by the shareholder.
Before deciding on a share structure, consider:
Decide the exact percentage each shareholder should own.
Ownership and voting power are often connected, but different share classes can separate them.
Decide whether shareholders should receive dividends in proportion to their ownership or whether different rights are required.
Consider whether the company may issue shares to investors in the future.
Decide whether shares or share options may eventually be offered to employees.
Establish what happens if a shareholder resigns, dies, becomes incapacitated or wants to sell.
Consider which decisions require a simple majority, a special resolution or unanimous consent.
Issuing, transferring or changing shares can create tax consequences for the company and its shareholders.
Certain ownership percentages can affect control of a UK company.
Common thresholds include:
These thresholds can materially affect company decisions. Share allocations should therefore be chosen carefully rather than treated as a purely administrative detail.
Yes. A company may be able to:
The company must follow the Companies Act 2006, its articles of association and any shareholders’ agreement. Resolutions and Companies House filings may also be required.
Companies House must normally be notified within one month when the company issues additional shares. Other changes to the share structure may need to be reported within 21 days. GOV.UK guidance
A shareholders’ agreement is strongly worth considering when a company has two or more shareholders.
It can cover:
The agreement should work alongside the company’s articles of association.
Businesses should avoid:
Yes. A company limited by shares may be incorporated with one shareholder holding one share. However, issuing more shares can make future ownership changes easier.
One share is simpler for a sole owner with no plans to introduce other shareholders. One hundred shares provide greater flexibility because each share can represent 1% of the company.
No, but they create nominal share capital of £100. If the shares are not fully paid, the shareholders may remain liable for the unpaid amount.
Yes. However, they should plan how deadlocks will be resolved if they disagree.
Yes. Directors do not have to own equal percentages, and a director does not necessarily have to be a shareholder.
Yes, provided it follows the required authorisation, pre-emption, documentation and filing procedures. Issuing new shares may dilute existing shareholders.
For many small UK limited companies, a simple structure of 100 ordinary shares is a practical starting point. It makes ownership percentages easy to calculate and offers flexibility if shares are transferred or new shareholders join later.
A sole-owner business may need only one ordinary share. Companies with several founders, investors, employees or family shareholders may require a more carefully designed arrangement.
The best structure is the one that accurately reflects the agreed ownership, voting control, dividend rights and long-term plans of the business. Legal and tax advice should be obtained before using multiple share classes or introducing complex shareholder rights.
