Share capital in a UK limited company: what it is, how to structure it, and when it matters

When a UK limited company is incorporated, it issues shares. The people who hold those shares are the company's members, or shareholders. In a typical small Arab-owned UK company, there is one director who is also the sole shareholder — they own 100% of the company's shares and make all decisions. The share capital in this case is usually 100 shares with a nominal value of £1 each, giving a total share capital of £100. This minimal structure is entirely legal and entirely normal for small UK companies. The nominal value of shares has nothing to do with what the company is worth — it is a legal formality, not a market valuation.

The authorised share capital is the maximum number of shares a company can issue (this concept was abolished for companies incorporated after October 2009 — modern UK companies can issue as many shares as the directors and shareholders agree, without a pre-set maximum). The issued share capital is the number of shares actually in existence and allocated to shareholders. Paid-up share capital is the amount shareholders have actually paid the company for their shares. In most small companies, these amounts are the same: 100 shares issued, 100 shares paid, £100 total share capital. The distinction matters mainly in larger or investment-context companies where shares are issued but not fully paid.

Shares can be ordinary shares (the standard, voting, dividend-receiving type), preference shares (which may have fixed dividends and priority on liquidation but usually no voting rights), or other classes defined in the company's Articles of Association. Most small Arab-owned UK companies have only ordinary shares, and only one class. This is the simplest and most common structure. If you want to bring in a business partner at some point, the cleanest mechanism is either transferring some of your existing shares to them (a share transfer) or issuing new shares from the company's unissued pool (a new share allotment). The paperwork differs: new allotments are notified to Companies House on form SH01, while an ordinary share transfer uses a stock transfer form (J30) held in the company's own records — no immediate Companies House filing, the new ownership simply appears on the next confirmation statement. (Form SH03 is something else entirely: it notifies Companies House when a company buys back its own shares.)

Share transfers between individuals have Stamp Duty implications in the UK. Stamp Duty is charged at 0.5% of the consideration paid for the shares, rounded up to the nearest £5. It is payable to HMRC on transfers where the consideration exceeds £1,000, and the company cannot register the transfer in its own statutory records until the stock transfer form has been stamped. For small companies where shares are transferred at nominal value (£1 per share), Stamp Duty may be negligible. For companies that have grown in value since incorporation, the consideration paid on transfer may be significantly above nominal value, creating a larger Stamp Duty obligation and, for the seller, a potential Capital Gains Tax liability on the gain.

A point that matters for Arab directors thinking about long-term ownership: the structure you choose at incorporation is not locked in permanently, but changing it later involves more administrative steps than getting it right from the start. If you anticipate bringing in a partner, taking on investors, or operating as a joint venture, it is worth discussing the share structure and any voting or dividend preference arrangements at the outset. A simple one-class ordinary share structure is flexible and sufficient for most small companies. For more complex arrangements — multiple shareholders, different voting rights, dividend preferences — a solicitor or corporate accountant should advise on the Articles of Association before shares are issued.
