As a business owner in the UK, it is crucial to understand the concept of paid-up capital and its legal implications. Paid-up capital, also known as paid-in capital or contributed capital, refers to the amount of money or assets a company has received from shareholders in exchange for shares. This article will explain the key legal requirements and considerations surrounding paid-up capital for UK businesses, including how it is created, reported, and regulated. It will cover the relevant provisions of the Companies Act 2006 and other applicable regulations to help you ensure compliance and make informed decisions about your company’s share capital structure.

What is Paid-Up Capital?

Paid-up capital is the total amount of money shareholders have paid to a company in exchange for shares. It consists of two main components.

The nominal value of the shares is the first component of paid-up capital. The second component is any premium paid above the nominal value, which is referred to as the share premium.

For example, if a company issues 100 shares with a nominal value of £1 each at a total price of £10 per share, the total paid-up capital would be £1,000 (£100 nominal value + £900 share premium).

Paid-up capital is an essential metric for assessing a company’s financial strength and the level of shareholder investment. 

The Companies Act 2006 sets out several key requirements related to share capital:

Minimum Share Capital Requirements

There is no minimum share capital requirement for private limited companies in the UK. However, public companies must have a minimum allotted share capital of £50,000 before they can commence business or borrow money.

Nominal Value

All shares must have a fixed nominal value, such as £1 per share. It is important to note that shares cannot be issued at an amount lower than their nominal value; however, a Company could undertake a share split, resulting in a new nominal value.

Payment for Shares

Shares, such as property or services, can be paid for in cash or non-cash consideration. Private companies can issue partly paid shares, and the unpaid amount becomes a debt owed to the company.

What Happens When Shares Are Partly Paid?

When a company issues partly paid shares, the unpaid amount is a legal debt owed to the company. The company can call in that debt at any time, unless the share terms set a specific date. If a shareholder fails to pay when called upon, the company can enforce payment through the courts.

Directors should keep clear records of any unpaid amounts in the share register. This helps avoid disputes and keeps your Companies House filings accurate. For example, if a shareholder pays £5 for a £10 share, the remaining £5 stays as a liability on the company’s books until paid.

This is particularly relevant for early-stage companies that issue shares before receiving full payment from founders or investors.

Reporting Requirements

Companies must maintain a register of members showing details of shares held and paid-up amounts—this is known as a share register or, sometimes, a members register.

Share Premium Account

When shares are issued at a premium (above their nominal value), the excess must be credited to a separate share premium account. 

This account is treated as part of the company’s capital and cannot generally be distributed as dividends. However, it can be used for specific purposes, such as paying for bonus shares or writing off preliminary expenses.

Maintenance of Capital

The capital maintenance principle is fundamental to UK company law and aims to protect creditors. Key aspects include restrictions on returning capital to shareholders except through prescribed methods, such as dividends, share buybacks, or capital reductions. 

Private companies in the UK are generally exempt from the prohibition on financial assistance for purchasing their own shares or shares of their private holding company. 

However, company directors still need to be careful and ensure it will not cause financial problems. It is a good idea to ask shareholders if they agree with the decision.

Alterations to Share Capital

Companies can alter their share capital in various ways, subject to legal requirements. One such alteration is the allotment of new shares, which requires proper authorisation. 

Companies can also consolidate or subdivide shares. Capital reduction is another option, but special procedures are required to protect creditors. Subject to specific rules, redemption or repurchase of shares is also possible.

Consequences of Non-Compliance

Failure to comply with legal requirements related to paid-up capital can have serious consequences. Transactions that breach capital maintenance rules may be void, and directors could be held liable. 

It is also important to note that failure to file accurate information with Companies House could be deemed a criminal offence.

  1. 92%: UK private companies maintain minimal paid-up capital (typically £1 or £100), reflecting standard practice for limited liability entities.
  2. 4.8 million: Active companies on the UK register with paid-up share capital, highlighting its fundamental role in corporate structures.
