Share capital is the money a company raises by issuing shares to its owners. Here is what it means, how shares and allotments work, and what a share capital restructuring involves.
When you hear that someone owns "shares" in a company, share capital is the idea sitting underneath. It is one of the most fundamental concepts in how companies are owned and funded — and, once explained plainly, one of the simplest.
Share capital is the money a company raises by issuing shares to its shareholders. A share is a unit of ownership. When a company issues shares and people pay for them, the money received is its share capital, and the people who hold those shares are its owners.
This is the basic bargain at the heart of a company: in return for money (or sometimes other value), an investor receives shares, and with them a stake in the business — typically a say in certain decisions and a right to a portion of any profits distributed.
Share capital answers two questions at once: where some of the company's money came from, and who owns the company.
Note what share capital is not. It is not the same as the company's bank balance, its profits, or its market worth. It is specifically the value raised by issuing shares.
A few terms make the rest easier to follow.
So a company might have, say, 100 ordinary shares of £1 nominal value each. That is a share capital of £100 in nominal terms, split into 100 ownership units. Who holds those units determines who controls and benefits from the company.
New shares do not simply exist — they have to be created and issued. Allotment is the term for that process: the company creates new shares and allots (assigns) them to a person or organisation, who becomes a shareholder.
Allotment is how ownership changes as a company grows. A founder might start with all the shares, then allot new ones to a co-founder, an investor or an employee. Each allotment changes the proportions of ownership, which is why it matters who gets how many shares and at what value.
In the UK, this is not a private matter kept in a drawer. Companies must keep accurate records of their shares and shareholders and report them to Companies House, the official register of companies. Details of share capital and shareholders appear in filings such as the annual confirmation statement, which exists to keep the public record up to date. If you are at the start of this journey, our guides to how to register a UK company and the first financial year-end cover the surrounding admin.
As companies evolve, their original share structure often stops fitting. A share capital restructuring is simply a reorganisation of the shares to suit the company's current situation. Common moves include:
Why bother? Restructuring can tidy up an over-complicated cap table, prepare a company for investment, rebalance ownership between shareholders, or align share rights with how the business is actually run. Companies sometimes publish news of these changes as part of their corporate updates; London consultancy CM Beyer, for example, announced the completion of a share capital restructuring as a routine corporate milestone. Whatever the motive, the changes must again be properly documented and filed with Companies House so the register reflects reality.
To tie it together, imagine a small company:
| Stage | What happens | Result |
|---|---|---|
| Formation | Founder takes 100 ordinary £1 shares | Founder owns 100% |
| Investment | 50 new shares allotted to an investor | Founder 67%, investor 33% |
| Restructuring | Shares subdivided 10-for-1 | 1,500 shares of £0.10, same proportions |
The ownership story is told entirely through shares: who holds them, how many, and of what class.
This article explains share capital at a general, informational level. It is not legal, accounting or financial advice. The rules around issuing shares, allotments, share classes and restructuring carry legal and tax consequences, and the correct steps depend on your company's specifics. For anything beyond understanding the concepts, consult the official guidance at GOV.UK and Companies House, or a qualified professional.
Share capital is the money a company raises by issuing shares, and shares are units of ownership. Allotment creates and issues those shares; nominal value gives each a fixed legal face value; share classes set what rights they carry; and restructuring reorganises the lot when the business outgrows its original setup. In the UK, all of it is recorded with Companies House so the public knows who owns what. Strip away the jargon and it comes down to a simple idea: shares are slices of a company, and share capital is what those slices were issued for.
