It is registered at Companies House and must comply with certain regulations, including filing annual accounts and confirmation statements. The term “limited” refers to limited liability, meaning the owners’ personal financial risk is limited to the amount they have invested in the company.
Limited companies can be either private (Ltd) or public (PLC), but most small businesses in the UK operate as private limited companies. This structure provides credibility and can make it easier to raise finance, enter contracts, and take on employees.
Limited Liability Explained
One of the key benefits of forming a limited company is limited liability. This means that as a shareholder or director, you are not personally responsible for the company’s debts beyond the value of any shares you own or any personal guarantees you have given.
For example, if your limited company faces financial difficulties or goes into debt, creditors can only pursue the company’s assets—not your personal possessions like your home or savings. This contrasts sharply with sole traders and traditional partnerships, where owners have unlimited liability.
How Limited Liability Works in Practice
When you set up a limited company, you must issue at least one share. Your liability is limited to the value of those shares. If you own 100 shares at £1 each, your maximum personal loss is £100 if the company fails.
However, limited liability does not protect against wrongful or fraudulent trading. Directors must comply with company law and act responsibly, or they could be held personally liable.

Limited Company vs Sole Trader and Partnership
Many new business owners wonder whether to register as a limited company or operate as a sole trader or partnership. Each structure has pros and cons depending on your circumstances, business goals, and appetite for risk.
Here are some key differences:
- Taxation: Limited companies pay corporation tax (19% for profits up to £50,000 in 2026/26). Sole traders and partners pay income tax on their profits at rates of 20% to 45%, plus National Insurance Contributions (NICs).
- Liability: Sole traders and partners have unlimited liability, meaning personal assets are at risk if the business fails. Limited companies offer limited liability protection.
- Administration: Limited companies face more paperwork and compliance, including annual accounts, confirmation statements, and corporation tax returns.
- Perception: Limited companies are often seen as more professional and trustworthy by clients, suppliers, and lenders.

How to Set Up a Limited Company
Setting up a limited company in the UK is a straightforward process that can be completed online through Companies House. You will need to provide:
- A company name that is unique and complies with naming rules.
- The company’s registered office address in the UK.
- Details of at least one director (must be a natural person aged 16 or over).
- Details of shareholders and share capital.
- The company’s articles of association (standard templates are available).
Once registered, you will receive a certificate of incorporation confirming your company’s legal existence. You must then register for corporation tax with HMRC within three months of starting to trade.
For more detailed guidance, visit the GOV.UK company formation page.
Running a Limited Company: What You Need to Know
After forming your limited company, there are ongoing responsibilities to keep it compliant and operating smoothly:
- Annual Accounts: You must prepare and file annual accounts with Companies House.
- Confirmation Statement: Submit a confirmation statement (previously annual return) each year confirming company details.
- Corporation Tax: File corporation tax returns with HMRC and pay any tax due.
- Record Keeping: Maintain accurate financial and company records.
- Directors’ Duties: Directors must act in the company’s best interests and comply with company law.
You can find detailed checklists and deadlines on the GOV.UK running a limited company page.
Who Suits a Limited Company?
Limited companies are well suited to business owners who:
- Want to limit personal financial risk.
- Plan to grow their business, employ staff, or raise investment.
- Are prepared to handle more administration and compliance.
- Wish to benefit from potential tax efficiencies, especially if profits are reinvested or paid as dividends.
Conversely, if you prefer simplicity, minimal administration, and keep business activity small-scale, a sole trader or partnership might be better.
Key Takeaways

What is the difference between a limited company and a sole trader?
A limited company is a separate legal entity offering limited liability protection, whereas a sole trader is personally responsible for all business debts. Limited companies pay corporation tax, while sole traders pay income tax on profits.
How much does it cost to register a limited company in the UK?
Registering a limited company online with Companies House costs £12 and usually takes 24 hours. Postal applications cost £40 and take 8 to 10 days. Additional costs may apply if you use an accountant or formation agent.
