A limited company is one of the most popular business types in the UK, giving owners legal separation and personal protection from the liabilities of the company. No matter what type of business you are planning to start in the UK, forming a limited company offers important legal and financial advantages, as we will explore in this article.
- Shareholders are only liable for the amount they invest, meaning personal assets like your home remain protected even if the company faces debt or litigation.
- Directors can draw a modest salary and top up income with dividends, often resulting in a lower overall tax liability compared to sole traders.
- Every director and person with significant control must now verify their identity with Companies House before a company can be registered, under recent legislation.
- A limited company offers perpetual succession, meaning it continues to exist even if the original owners or directors leave or pass away.
What is a UK limited company?
A limited company is a legal business structure that separates the business from its owners and directors while giving them the benefit of personal limited liability. As a separate legal person, a limited company can:
- Own assets (e.g. property and machinery)
- Enter into contracts with customers and suppliers
- Employ staff
- Pay taxes in its own right
Limited liability means that any financial risk to shareholders is restricted to the amount they invest in the company. Personal assets such as your home or car are protected if the company gets into debt or litigation, provided there is no wrongdoing by the directors involved. For many business owners, this legal separation is the single most important reason to form a limited company in the UK.
What are the types of limited company in the UK?
There are several types of limited company in the UK, including private company limited by shares, limited by guarantee and public limited company. The differences between each are as follows:
| Type of UK limited company | Description |
|---|---|
|
Private company limited by shares |
This is the most common type of limited company in the UK. Shares held by this type of company are owned privately and cannot be sold publicly. |
|
Limited by guarantee |
A company limited by guarantee is typically used by charities or non-profit organisations. With this type of business, there is no share capital because members act as guarantors. |
|
Public limited company (PLC) |
PLCs can offer shares to the public via the stock exchange. Requires a minimum share capital of £50,000. |
It is important to note that private limited companies (LTDs) are not just for large businesses; they can be used by single-owner operators, small and medium-sized businesses, national entities and multi-nationals. According to our company formations review, private companies limited by shares make up over 92.6 % of all UK corporate bodies, while companies limited by guarantee represent only a small fraction of the register — illustrating how dominant the private-share model remains in the UK corporate landscape.
Public limited companies tend to be complex to manage and are mainly used by large corporations looking to raise capital from public investors.
How does a limited company work?
To form a limited company in the UK, you first need to register your new business with Companies House, also referred to as the process of ‘incorporation’ (please see below). Once your limited company has been successfully registered with Companies House, your company is assigned a unique company number and becomes a legal entity in its own right.
Limited companies have shareholders and directors.
- A shareholder is someone who owns a share in a limited company and can invest capital and receive dividends if the company makes a profit.
- Directors are people responsible for running the company and ensuring legal compliance with the Companies Act 2006 and the rules defined by Companies House and HMRC. A director can also be a shareholder.
Limited companies are legally required to file annual accounts, maintain company records, and pay corporation tax on profits.
Any profit that remains after corporation tax has been paid can then either be distributed to shareholders or reinvested into the business (e.g. to buy new equipment).
What are the advantages of a UK limited company?
Forming a limited company in the UK offers several distinct advantages:
- Limited liability – limited liability protects the personal finances of shareholders because they are only liable for the amount they have invested.
- Tax efficiency – limited companies typically benefit from more tax-efficient arrangements compared to sole traders. Corporation tax is paid on profits, which is generally lower than the rates of income tax paid by sole traders. Company directors also have the option to draw a modest salary and add to their income with dividends, which can result in a lower overall tax liability.
- Can project a more professional image – simply having the letters ‘LTD’ after your business name can add credibility and build trust with your customers, suppliers and investors.
- Easier to raise funds – a limited company can issue shares and may attract external investors.
- Perpetual succession – a limited company continues to exist even if the original owners or directors leave or pass away.
What are the disadvantages of a UK limited company?
There are some disadvantages of limited companies to be aware of, as follows:
- More administration – to comply with the law, you will have to file annual accounts, confirmation statements, and maintain statutory registers, among other important tasks
- Public disclosure – company information, including directors’ names and financial accounts, is available to the public via Companies House
- More costs – there are setup and ongoing costs, including filing fees and accountant fees.
- Greater overall complexity – as a company director, you need to comply with the Companies Act 2006 and HMRC requirements, which can be time-consuming and increase the risk of non-compliance if you lack experience.
What are the main differences between a limited company and a sole trader?
The main differences between the two most popular business types are as follows:
| Feature | Limited company | Sole trader |
|---|---|---|
|
Legal status |
Separate legal entity |
Not separate from the owner |
|
Liability |
Limited to the value of investment |
Unlimited personal liability |
|
Taxation |
Corporation tax and dividends |
Income tax is payable on all profits |
|
Personal privacy |
Public disclosure is required |
No public disclosure required |
|
Ongoing costs |
Higher |
Lower |
In essence, while a sole trader setup is simpler and cheaper to run, it offers no personal liability protection for the shareholders. Limited companies, on the other hand, are more complex but offer greater protection and long-term flexibility. With that said, a trusted accountant will handle most of your financial accounting and filing requirements, allowing you to focus on your business.
How can I set up a limited company?
When it comes to setting up a limited company, there are two main methods: ‘Do it yourself’ (DIY) or through a formation agent such as Uniwide Formations. Regardless of the method you choose, the general process of incorporating a company remains the same; you will need to:
- Choose your company name – it must not be too similar or the same as another registered company. To make this process easier, we offer a company name check service on our website.
- Appoint at least one director – they will be responsible for managing the company and ensuring its legal compliance.
- Decide on your company shareholders – you must have at least one shareholder who can be the same person as the director.
- Allocate shares – decide how many shares to issue to shareholders and their value.
- Prepare your Memorandum of Association and Articles of Association – these foundational documents define how your company will be run. We can draft these for you based on your needs.
- File your company registration application online or through a company formation agent
- Pay the application fee
- Register for Corporation Tax with HMRC.
Every director and person with significant control must now verify their identity with Companies House before a company can be registered, a requirement introduced under the Economic Crime and Corporate Transparency Act. Most companies can be formed within 24 hours when registered online; however, we provide a same-day service if your application is placed by 1.30 pm Monday to Friday and you have passed our identity verification checks.
Directors and shareholders play different roles, and their responsibilities are clearly defined under UK company law.
Directors must:
- Act in the company’s best interests at all times
- Keep proper financial records
- File annual accounts and confirmation statements
- Ensure the company pays taxes on time
- Report changes in company structure or officers
Shareholders (who can also be directors):
- Own part of the company
- Vote on important company decisions
- Can appoint and remove directors
- Receive dividends
In small businesses, directors and shareholders are often the same individuals.
Ongoing compliance and reporting
Once your company is formed, you must meet ongoing reporting and compliance duties:
- Annual accounts – your limited company annual accounts must be filed with Companies House within nine months of the end of your financial year.
- Confirmation statement – this document confirms key company details held by Companies House and must be submitted at least once a year.
- Corporation Tax return – Must be filed with HMRC, along with full company accounts.
- Maintain statutory registers, including the:
- Register of members (shareholders)
- Register of directors
- PSC register (People with Significant Control)
- Report changes – you must notify Companies House of any changes to directors, registered address, or share structure.
Is a limited company the right choice for my new business?
Incorporating as a limited company may be the right choice for your needs if:
- You want to protect your personal assets from business risks
- You may need to raise investment or attract partners
- You expect to earn above the Income Tax threshold
- You want a professional business image for your customers, suppliers, and investors
- You want a clear separation between personal and business finances
Consider that the business you have now may grow and expand considerably in the coming years. While a sole trader structure may meet your immediate needs, it may be advantageous to start as a limited company from the outset.
UK Limited Companies: Frequently Asked Questions
Is a limited company the same as a limited liability partnership (LLP)?
No. An LLP is a different structure that combines limited liability with the flexibility of a partnership. Its owners are called members rather than shareholders, and it has no share capital. An LLP is also taxed differently: it is transparent for tax, so members pay tax on their share of the profits, whereas a limited company pays corporation tax in its own name.
How much corporation tax does a limited company pay?
A limited company currently pays corporation tax at 19% on taxable profits up to £50,000 and 25% on profits above £250,000. Profits between these figures are taxed at an effective rate in between, through marginal relief. Corporation tax is charged on the company’s profit, not on money the owners take out, and it is separate from the personal tax shareholders pay on dividends.
Can a non-UK resident set up a UK limited company?
Yes. There is no requirement for directors or shareholders to live in the UK or to be British. The company does need a UK registered office address. Every director and person with significant control must also complete Companies House identity verification, which people based overseas can do with a biometric passport through GOV.UK One Login, or through an authorised UK agent.
Do I need an accountant to run a limited company?
There is no legal requirement to use an accountant, and directors are allowed to prepare and file the company’s accounts themselves. In practice, most companies use one. Statutory accounts must follow set accounting standards, and corporation tax calculations can be involved, so mistakes can lead to penalties or rejected filings. An accountant also helps directors meet deadlines with confidence.
What is a limited company’s registered office address?
It is the company’s official address on the public register, where Companies House and HMRC send statutory mail. It must be a real address in the part of the UK where the company is registered. Since recent reforms, it must also be an appropriate address where post reaches someone acting for the company, so a PO box on its own is no longer acceptable.
Does a limited company have to register for VAT?
Not automatically. A company must register for VAT once its VAT-taxable turnover passes the registration threshold, currently £90,000 in any rolling 12-month period, or when it expects to pass it within the next 30 days. Below that level, registration is optional. VAT is separate from corporation tax and applies to turnover, regardless of whether the company makes a profit.
Can I use my home address for a limited company?
Yes, you can, but any address you give as the registered office or a director’s service address appears on the public register and can be seen by anyone. Many owners prefer not to publish their home address. To keep it private, you can use a separate service address and registered office address, which receive official mail on the company’s behalf while keeping your home details off the record.
Can I switch from being a sole trader to a limited company?
Yes. Many people start as a sole trader and later form a limited company as the business grows. You cannot simply convert one into the other, though. Instead, you register a new company and move the business activity across to it, then decide whether to keep the sole trade running or close it. It is worth planning the timing so contracts, bank accounts, and tax responsibilities transfer cleanly.
Deciding on a Limited Company
By registering a limited company in the UK, you gain valuable legal protection, potential tax advantages, and a structure that helps you build trust with clients, suppliers, and investors. In return, directors take on statutory duties, including keeping proper records and filing on time. For most founders, the choice comes down to how much personal protection and room to grow the business needs from the start, set against the extra administration that a company involves.
