When people picture British business, they often imagine large, recognisable companies. The reality is rather different: the overwhelming majority of UK businesses are very small indeed — micro-businesses, typically run by one person or a handful. They are the trades, shops, agencies, consultancies and service firms that, taken together, make up the bulk of the country’s business population and a substantial share of its employment. This is commentary on the scale and importance of micro-business Britain, and a practical look at how legal structure — sole trader versus limited company — shapes a business’s options, including for finance.
The scale of the small
It is hard to overstate how dominant small businesses are by number. The great majority of UK private-sector businesses have no employees beyond the owner, or only a few. Government statistics on the business population, published via gov.uk, consistently show that micro and small businesses account for the vast bulk of all firms. We will not put a precise figure on it here — the numbers move year to year, and we would rather you consult the official source than a stale statistic — but the qualitative picture is unambiguous: most British businesses are very small.
That matters because policy, banking and commentary often default to the needs of larger firms, while the typical business is nothing like them. The micro-business — under-capitalised, time-poor, run by people wearing every hat at once — is the norm, not the exception. Understanding its realities is understanding most of the economy.
Why micro-businesses matter
Their importance is not just about headcount. Micro-businesses provide local services, employ people in their communities, and offer a route to independence and livelihood for millions. They are also disproportionately exposed to the pressures we have written about elsewhere — late payment, cash-flow gaps, and difficulty accessing mainstream finance — precisely because they are small. The health of micro-business Britain is, in a real sense, the health of the everyday economy.
Sole trader vs limited company
One of the most consequential decisions a micro-business makes is its legal structure, and it directly affects how it can borrow. The two most common forms could hardly be more different in law.
Sole trader
A sole trader is not legally separate from the person running the business. In law, the individual and the business are one and the same. That brings simplicity — fewer formalities, easier setup — but also means the owner is personally responsible for the business’s debts. Borrowing by a sole trader is, legally, borrowing by an individual.
Limited company (and LLP)
A limited company, or a limited liability partnership, is a separate legal person — a body corporate — distinct from its owners. It can own assets, enter contracts and borrow in its own name, and its debts are, as a starting point, the company’s rather than the directors’ personally. This separation is the foundation of limited liability, and it changes the lending picture significantly.
What the structure means for finance
The distinction is not academic when it comes to borrowing. Because we lend to a body corporate rather than an individual, who you are in law determines whether you can borrow from us at all. We lend to UK limited companies and LLPs, for business purposes, to the company rather than to its director personally — and we take no personal guarantee. A sole trader, being an individual in law, falls outside that model. We set out who is eligible in our eligibility article, and the options for sole traders considering incorporation in moving from sole trader to limited company before seeking finance.
The structure also affects the regulatory position. Lending to a company for business purposes sits outside FCA consumer-credit regulation under Article 60B FSMA RAO 2001 — one reason our product is built around bodies corporate. You can see what we currently offer on our business loans page.
The takeaway
Micro-businesses are not a niche; they are the substance of the UK economy, and their realities deserve to sit at the centre of how finance is designed rather than the periphery. For any micro-business owner, the legal structure you choose is one of the most far-reaching decisions you will make — shaping your liability, your tax, and your access to credit. It is worth getting right, and worth understanding before you borrow. The official business-population data is the place to grasp the scale; the structure question is the place to start when thinking about finance.
