Issued share capital is the total nominal value of the shares a company has actually issued to its shareholders. For example, if a UK limited company issues 1,000 ordinary shares with a nominal value of £1 each, its issued share capital is £1,000. If the same company issues 1,000 shares with a nominal value of 1p each, its issued share capital is only £10.

This distinction matters because issued share capital is not the same thing as the company's market value, the amount of money in its bank account, or the amount investors have paid for its shares. For founders setting up a UK limited company, understanding issued share capital helps make sense of Companies House records, ownership percentages, share allotments, investment rounds and the company's statement of capital.

What Does Issued Share Capital Mean?

Issued share capital is the nominal value of the shares that a company has issued and allotted to shareholders. The important word is issued. A company may have the ability to issue additional shares in the future, but those shares do not form part of its issued share capital until they have actually been allotted.

Companies House describes issued capital as the value of shares issued to shareholders, measured by their nominal value rather than their actual or market value. A company can increase its issued capital by allotting additional shares, provided the allotment is properly authorised.

A simple example

Imagine that you incorporate a company with:

• 100 ordinary shares
• £1 nominal value per share
• One shareholder owning all 100 shares

The calculation is: 100 shares × £1 nominal value = £100 issued share capital, The shareholder owns 100% of the company. Now suppose the company later issues another 900 ordinary shares to an investor. It would then have:

• 1,000 shares in issue
• £1 nominal value per share
• £1,000 issued share capital

The original shareholder now owns 10%, while the new investor owns 90%, assuming all shares carry identical rights. The company's issued share capital has therefore increased from £100 to £1,000.

How Is Issued Share Capital Calculated?

The basic formula is straightforward:

Issued share capital = number of issued shares × nominal value per share

Consider these examples:

UK company law requires shares in a limited company with share capital to have a fixed nominal value. The Companies Act 2006 permits shares to be denominated in different currencies, subject to the applicable rules.

This is why the number of shares alone does not tell you the amount of issued share capital. 1,000 shares at £1 each and 1,000 shares at 1p each represent the same number of shares but very different nominal share capital.

Issued Share Capital vs Share Capital

The terms can be confusing because "share capital" is often used as a general expression. In practical company administration, issued share capital refers to the nominal value of shares that have actually been issued. For example, if a company has issued 500 shares at £1 each: Issued share capital = £500

Companies House uses a statement of capital to show a snapshot of a company's share capital at a particular point in time. It includes information such as the total number of shares, aggregate nominal value and amounts paid or unpaid. The distinction becomes particularly important when a company creates or issues additional shares.

Issued Share Capital vs Authorised Share Capital

This is one of the most common areas of confusion. Historically, UK companies could have something called authorised share capital, which placed a ceiling on the amount of shares a company could issue. That system changed under the Companies Act 2006.

The Act abolished the old authorised share capital regime, so a modern UK private limited company does not generally have an authorised share capital limit that it must stay below. Therefore, founders should be cautious when reading older articles that say something like:

"A company has £100 issued share capital but £1,000 authorised share capital."

That terminology generally reflects the old company-law framework rather than how a newly incorporated UK company operates today. For a modern company, the more useful questions are:

• How many shares have actually been issued?
• What is their nominal value?
• Who owns them?
• What rights attach to each class?
• How much has been paid or remains unpaid?
• Will additional shares be issued later?

Issued Share Capital vs Paid-Up Share Capital

Issued share capital and paid-up share capital are related, but they are not necessarily identical. A share can be issued with an amount that remains unpaid. For example, suppose a company issues: 1,000 shares at £1 each, Its issued share capital is: £1,000. If the shareholders have paid the full £1 per share, the shares are fully paid and there is no amount outstanding. But if only 60p per share has been paid, then:

• Issued share capital: £1,000
• Amount paid: £600
• Amount unpaid: £400

Companies House requires statements of capital to show the aggregate amount unpaid on shares where applicable. This matters because an unpaid amount can represent a continuing obligation associated with the shares. For most straightforward founder-owned companies, shares are commonly issued fully paid, making the distinction relatively simple. More complex structures may use partly paid shares for specific commercial or investment reasons.

Issued Share Capital vs Market Value

Perhaps the most important distinction is this: Issued share capital does not tell you what a company is worth. Suppose a technology startup has:

• 1,000 ordinary shares
• £1 nominal value per share
• £1,000 issued share capital

The company could potentially be valued at:

• £10,000
• £100,000
• £1 million
• £10 million

The £1,000 issued share capital does not determine the company's valuation. The nominal value is essentially the fixed face value attached to the shares. The economic or market value can be completely different. For example, an investor might subscribe for 100 new £1 shares for £50 per share.

The company receives £5,000. But the nominal value of those shares is only: 100 × £1 = £100, The remaining £4,900 represents the amount paid above nominal value — commonly referred to as a share premium. This is why a company's issued share capital can remain relatively small even when significant investment has been made.

Does Issued Share Capital Determine Ownership?

Not by itself. Ownership percentages are normally determined by the number and rights of shares held relative to the total issued shares. Consider a company with:

• Founder: 800 ordinary shares
• Investor: 200 ordinary shares
• Total: 1,000 ordinary shares

The founder owns: 800 ÷ 1,000 = 80%, The investor owns: 200 ÷ 1,000 = 20%, If each share has a £1 nominal value, the company's issued share capital is £1,000. But the £1,000 does not mean the founder owns £800 worth of the company and the investor owns £200 worth.

The numbers represent the nominal value of the shares, while the ownership percentages come from the shareholding structure and the rights attached to those shares. This distinction becomes especially important when discussing startup investment.

Why Does Issued Share Capital Matter for Startups?

Issued share capital becomes increasingly important as a business grows. A founder may initially issue 100 or 1,000 ordinary shares simply to establish a straightforward ownership structure. Later, the company may:

• Bring in an investor
• Give shares to a co-founder
• Create an employee share arrangement
• Issue shares to raise funding
• Create a new class of shares
• Reorganise its existing share structure
• Dilute existing shareholders

Every new issue can affect the company's ownership structure.

Example: bringing in an investor

Suppose Sarah owns all 1,000 shares in a startup. She therefore owns 100%. An investor agrees to invest in exchange for 250 newly issued ordinary shares. After the allotment:

• Sarah: 1,000 shares
• Investor: 250 shares
• Total: 1,250 shares

Sarah now owns: 1,000 ÷ 1,250 = 80%, The investor owns: 250 ÷ 1,250 = 20%, The investor's 250 shares increase the company's issued share capital and reduce Sarah's percentage ownership. This is called dilution. The important point is that dilution happens because new shares are issued, not because the nominal value of existing shares suddenly changes.

What Does Companies House Show About Issued Share Capital?

Companies House records share capital through the company's statement of capital. The statement provides a snapshot of the company's share capital at a particular time. Depending on the circumstances, it can show:

• Total number of shares
• Aggregate nominal value
• Share classes
• Number of shares in each class
• Rights attached to each class
• Amount paid
• Amount unpaid

Companies House guidance explains that the statement of capital forms part of various filings involving share capital, including incorporation and certain changes to the company's shares. This makes the statement of capital particularly useful when checking the ownership and capital structure of a UK company.

What Happens When a Company Issues More Shares?

Issuing additional shares changes the company's capital structure. For example: Before issue

• 1,000 ordinary shares
• £1 nominal value
• £1,000 issued share capital

The company then allots another 500 ordinary shares. After issue

• 1,500 ordinary shares
• £1 nominal value
• £1,500 issued share capital

A UK company generally needs to notify Companies House when it issues additional shares. GOV.UK states that new shares must generally be reported within one month of being issued. The filing normally includes the relevant statement of capital. For an allotment of new shares, form SH01 is used to notify Companies House. Companies House guidance explains that the form records the new shares allotted and the resulting share capital information.

This is an important compliance point for founders. Issuing shares is not simply an internal agreement between a founder and investor; the company's statutory records and Companies House filings need to reflect the change.

Does Issued Share Capital Mean Money in the Company's Bank Account?

No. This is another common misunderstanding. If a company has £1,000 issued share capital, it does not necessarily mean there is £1,000 sitting in its bank account. The shares may have been issued for different amounts, depending on the circumstances. For example, 1,000 shares with a nominal value of £1 could be issued for:

• £1 each
• £5 each
• £20 each

If they were issued for £20 each, the company could receive £20,000, while the nominal share capital is still £1,000. The difference between nominal value and the amount paid above nominal value is important when understanding the company's accounts and share premium.

How Much Issued Share Capital Should a UK Company Have?

There is no universal "correct" amount for every company. A founder should think about the company's circumstances rather than choosing a large number simply because it sounds more substantial. For a simple startup, a structure such as: 100 ordinary shares at £1 each creates £100 of issued share capital. Another founder might prefer: 1,000 ordinary shares at £1 each, creating £1,000 of issued share capital. Or: 10,000 ordinary shares at 1p each, also creates £100 of issued share capital.

The better structure depends on how the founders intend to divide ownership and whether they expect to issue additional shares later. The number of shares can be particularly useful for expressing ownership percentages. For example, 1,000 shares make it easy to allocate 70/20/10 ownership between three founders. But there is no requirement to create an artificially large share capital simply to make the business appear larger.

Issued Share Capital and Different Share Classes

Not every company has just one type of share. A company can have different share classes with different rights. For example:

• Ordinary shares
• Preference shares
• Alphabet shares
• Shares with different voting rights
• Shares with different dividend rights

Companies House requires the statement of capital to provide information about the rights attached to each class. This becomes particularly relevant when a startup raises external investment.

An investor may negotiate rights that differ from those of ordinary founder shares. The commercial value of the arrangement therefore cannot be understood simply by looking at the total number of shares. For more sophisticated structures, founders should consider professional legal and accounting advice before changing share rights or creating new classes.

Issued Share Capital and Confirmation Statements

A company's share capital information is also relevant to its annual confirmation statement. Companies House requires companies to review and confirm that their registered information is correct at least every 12 months. Where applicable, this includes the company's statement of capital and shareholder information.

If the company's share structure has changed, founders should make sure the Companies House record accurately reflects the current position. However, not every share-related change should simply be left until the next confirmation statement. Certain changes, including new share allotments, have separate filing requirements and deadlines. That distinction is important: A confirmation statement is not a substitute for making an event-driven share filing when one is required.

Common Mistakes About Issued Share Capital

1. Thinking issued capital equals company value

It does not. Nominal share capital and market valuation are separate concepts.

2. Confusing issued shares with authorised shares

The old authorised share capital concept is no longer the normal framework for new UK companies.

3. Assuming the nominal value is the selling price

A £1 nominal-value share can be issued for significantly more than £1.

4. Ignoring dilution

Issuing new shares can reduce existing shareholders' percentage ownership.

5. Forgetting unpaid amounts

Where shares are not fully paid, the unpaid amount needs to be properly recorded.

6. Issuing shares without considering the company's existing structure

Before issuing shares, founders should consider existing shareholders, voting rights, share classes, pre-emption considerations and the company's constitutional documents.

A Practical Checklist for Founders

Before issuing shares, ask:

1. How many shares are currently issued?
2. What is the nominal value of each share?
3. Who currently owns the shares?
4. Are the existing shares fully paid?
5. What percentage will each shareholder own after the new issue?
6. Will the new shares have the same rights as existing shares?
7. Does the company have the necessary authority to allot the shares?
8. Will the transaction create dilution?
9. What price will the new investor actually pay?
10. What Companies House filing is required?

For global founders managing a UK company remotely, keeping these details organised is especially important. Platforms such as IncorpUK can be useful as part of the wider administrative infrastructure around UK company formation and management, while legal, tax and accounting decisions may require appropriately qualified professional advice.

Frequently Asked Questions About Issued Share Capital

What is an example of issued share capital?

If a company issues 1,000 ordinary shares with a nominal value of £1 each, its issued share capital is £1,000.

Is issued share capital the same as share capital?

The terms are often used broadly, but issued share capital specifically refers to the nominal value of shares that have actually been issued. Companies House records this through statements of capital.

Is issued share capital the same as company valuation?

No. Issued share capital is based on the nominal value of issued shares. Company valuation reflects the economic or market value of the business and can be many times higher.

Does issued share capital have to be £1?

No. A UK company can issue shares with different nominal values, subject to the applicable company-law requirements. Shares in a limited company with share capital must have a fixed nominal value.

Can a company increase its issued share capital?

Yes. A company can generally increase its issued share capital by allotting additional shares, provided the necessary authority and legal requirements are satisfied. New share issues generally need to be notified to Companies House within one month.

Does issuing more shares dilute existing shareholders?

Usually, yes, if new shares are issued to someone else and existing shareholders do not receive a corresponding number of shares. Their percentage ownership can decrease even though the number of shares they personally hold remains unchanged.

Can shares be issued for more than their nominal value?

Yes. A share with a £1 nominal value can be issued for more than £1. The amount paid above nominal value is treated separately from the nominal share capital.

What happens if shares are partly paid?

The unpaid amount remains outstanding in accordance with the terms of the shares. Companies House's statement of capital records aggregate amounts unpaid where applicable.

Where can I see a company's issued share capital?

The company's Companies House record and relevant statement of capital provide information about its issued shares, nominal values, classes and related capital information.

Conclusion: Understand the Number Behind the Shares

Issued share capital is one of the simplest concepts in UK company law once the terminology is separated from company valuation and investment. At its core:

Issued share capital is the total nominal value of the shares a company has actually issued.

The calculation is straightforward: Number of issued shares × nominal value per share = issued share capital, But the implications go further. Issued share capital helps establish the company's formal share structure, records the nominal value of ownership interests, affects how new shares are reflected at Companies House and provides the foundation for understanding changes in ownership when additional shares are issued.

For a founder, the most important distinction is between nominal value, ownership percentage, investment price and company valuation. They are connected, but they are not interchangeable. Once you understand that difference, Companies House share records, statements of capital, share allotments and startup investment structures become much easier to interpret and much harder to get wrong.
