Business Ownership & Limited Liability
Why Legal Structure Matters
Before a business trades, its owners have to decide what kind of organisation it will be. The legal structure chosen affects how much control the owners keep, how profits are shared, where the business can raise money, and crucially, what happens if things go wrong. A self-employed dog walker and Tesco PLC are both businesses, but they operate under very different rules. Choosing the wrong structure can cripple a good idea — so this decision is one of the first serious tests for any entrepreneur.
Sole Traders
A sole trader is a business with one owner. Think of a local plumber, a market-stall holder or a personal trainer. Setting up is simple: register with HMRC and start trading. The owner keeps all the profit and makes every decision. The downside is the same detail that makes it attractive — the owner is the business in the eyes of the law. They face unlimited liability, meaning if the business owes money it cannot repay, creditors can come after the owner’s house, car and savings.
Sole traders keep all the profit and have full control, but they have unlimited liability and limited ways to raise finance. Most UK businesses are sole traders — simple to set up, but risky if the business fails.
Partnerships
A partnership has two or more owners (the old 20-partner limit was removed in 2002) who share the workload, combine their skills and pool capital. A high-street solicitor, a local accountancy firm and most GP surgeries run as partnerships. Decisions are shared, profits are split according to a partnership agreement, and more finance can be raised than by one individual. The drawback is that partners still have unlimited liability — and one partner’s mistake can land the others with the bill. Disagreements between partners also slow decisions.
Private Limited Companies (Ltd)
A private limited company (Ltd) is a separate legal entity owned by shareholders. Shares can be sold to family, friends or invited investors but not to the general public. Most UK companies with ‘Ltd’ at the end — Greggs was one before it floated, Dyson still is — fall into this category. The crucial advantage is limited liability. If the company goes bust, shareholders can only lose the money they put in; their personal assets are safe. In return, Ltds must register at Companies House and publish annual accounts.
Public Limited Companies (Plc)
A public limited company (Plc) can sell shares to the general public through the stock exchange. Tesco PLC, BT Group PLC and JD Sports Fashion PLC are household examples. Going public opens up huge sources of finance — millions of pounds can be raised in a single share issue — and raises brand profile. The catch: ownership is diluted, takeovers become possible, and every result is scrutinised by shareholders and the press. Plcs also face strict reporting and must publish detailed annual reports.
Both Ltds and Plcs have limited liability and are separate legal entities. The key difference is how they raise money. An Ltd can only sell shares to people it invites; a Plc can sell to anyone through the London Stock Exchange. That changes the scale of finance available — and the amount of outside control the owners must accept. When Aston Martin floated as a Plc in 2018, the owners accepted public scrutiny of every quarterly result in return for the cash to expand globally.
The decision to move from Ltd to Plc is called a flotation or Initial Public Offering (IPO). Many UK family businesses stay as Ltds precisely because they want to keep control inside the family. Going public is almost impossible to undo cheaply.
Not-for-Profit Organisations
Some organisations exist to serve a social or charitable purpose rather than to make profit for owners. Charities like Oxfam and the British Heart Foundation are not-for-profit organisations. They still have to cover costs, pay staff and manage cash — but any surplus is reinvested into the cause rather than paid out to shareholders. Social enterprises like The Big Issue operate the same way: they sell a product to fund a mission.
Limited liability protects the owners’ personal assets — it does not protect the business itself. A company can still go bust; limited liability simply caps how much each shareholder can personally lose at the amount they invested.
A lone builder just starting out will usually begin as a sole trader — cheap, simple, no reporting. Two dental graduates opening a practice together are suited to a partnership — shared skills, shared finance. A growing family catering business taking on larger contracts will often become a private limited company to protect the owners’ homes from supplier claims. A national retailer needing hundreds of millions to open stores will eventually list as a Plc. The right structure depends on the size of the business, the risk it faces, and how much outside finance it needs.
