Quick Answer

In everyday UK use, yes: most companies ending in “Ltd” are private companies limited by shares. Strictly, the terms overlap rather than match. A public limited company (plc) is limited but not private, and a private unlimited company is private but not limited. Your company’s type is recorded at Companies House.

You are about to set up a business, or you have just read “Ltd” on an invoice, and the wording starts to blur. Is a private and limited company one thing or two? The phrases appear side by side so often that most people assume they are interchangeable, yet UK company law treats “private” and “limited” as answers to two different questions.

This guide untangles them using Companies House definitions and the Companies Act 2006. It compares all four UK company types, decodes the name endings, explains how a limited company is taxed for 2026/27, and helps you see which structure fits your situation.

Key takeaways

“Private” describes who can buy the shares; “limited” describes how far the owners’ liability goes.
Most small UK businesses that incorporate become private companies limited by shares.
A plc is limited but public, and needs at least £50,000 of allotted share capital.
A private company’s name must end in “Limited” or “Ltd” (or the Welsh equivalent).
A limited company pays Corporation Tax; a sole trader pays Income Tax through Self Assessment.

Private and Limited Company: Do They Mean the Same Thing?

Think of the two words as separate switches. The first switch asks whether the company may sell its shares to the general public. The second asks whether the members are protected from the company’s debts. A typical small business has both switches set the same way: it is private, and it is limited. That combination is why “private and limited company” and “private limited company” are used as if they were one phrase.

The two switches can also be set differently. Companies House guidance on incorporation and names lists a private unlimited company, which is private but gives its members no cap on liability, and a public limited company, which is limited but may offer shares to anyone. So every private limited co is both private and limited, but not every limited company is private.

What is a private limited company?

Definition: A private limited company is a business registered at Companies House that is legally separate from its owners. Its shareholders’ liability is capped at any amount unpaid on their shares, it cannot offer shares to the general public, and its name must end in “Limited” or “Ltd”.

In plain terms, the company owns its assets, signs its own contracts and owes its own debts. You may also see it called a private limited firm or, in some countries, a “pvt ltd” business. Those labels describe the same idea, but in the UK the legal form is set out in the Companies Act 2006, not in the wording people use.

What is meant by limited company?

“Limited” refers to limited liability. GOV.UK’s business structures guidance explains that the owners of a limited company are responsible for its debts only up to the value of their investment. A sole trader, by contrast, has unlimited liability and is personally responsible for every business debt.

That protection is the main reason a private and limited company structure appeals to small business owners. It is not absolute, though. If you personally guarantee a bank loan or a lease, the lender can still come after you for that amount, whatever the company’s status.

The Four Types of UK Company Compared

Companies House recognises four company types. Seeing them side by side is the quickest way to understand where a private and limited company sits, and why the two words do not always travel together.

Company type	Private?	Limited?	Members’ liability	Typical use
Private company limited by shares (Ltd)	Yes	Yes	Capped at any amount unpaid on their shares	Most small and family businesses
Private company limited by guarantee	Yes	Yes	Capped at the sum each guarantor agreed to contribute on winding up; no share capital	Clubs, charities and not-for-profits
Private unlimited company	Yes	No	No limit	Specialist situations; rare for small firms
Public limited company (plc)	No	Yes	Capped at any amount unpaid on their shares	Larger businesses raising money from the public

Source: Companies House, Incorporation and names, section 1.3, checked October 2026. The “typical use” column is our general guide, not a legal rule.

Read the first row and you have the classic private and limited company. When someone says they “set up a limited company”, this is almost always what they mean. GOV.UK’s company formation guide notes that a company limited by shares needs at least one shareholder, while one limited by guarantee needs at least one guarantor, and in both cases that person can also be a director.

Private limited company vs public limited company (plc)

So what is a public limited company? It is a limited company that is allowed to offer its shares to the general public, and those shares may be quoted on a stock exchange. A private company cannot do that. The difference is not just about size; it changes the legal hurdles before trading starts.

Minimum capital: a plc must have allotted share capital of at least £50,000, under section 763 of the Companies Act 2006. A private company has no such minimum.
Paid-up shares: each plc share must be paid up to at least a quarter of its nominal value, plus any premium, under section 586.
Trading certificate: Companies House says a plc must obtain a trading certificate (form SH50) before it can do business or borrow.

For almost every sole trader thinking about incorporating, the plc route is irrelevant. The realistic choice is between staying a sole trader and becoming a private and limited company.

Ltd, Limited, plc: What the Name Ending Tells You

A company’s name ending is a legal signal, not branding. Companies House sets out what each type must use, so “Ltd” after a name tells you straight away that you are dealing with a private and limited company.

Name ending	What it tells you
Limited / Ltd	A private company limited by shares or by guarantee
Cyfyngedig / Cyf	The Welsh equivalent, available if the registered office is in Wales
Public limited company / plc	A public company, with or without full stops
Cwmni cyfyngedig cyhoeddus / ccc	The Welsh equivalent of plc

Source: Companies House, Incorporation and names, section 6.1, checked October 2026.

Ltd meaning: is “Ltd” different from “Limited”?

No. “Ltd” is simply the short form of “Limited”, and Companies House accepts either as the ending for a private company. A business called “Example Bakery Ltd” and one called “Example Bakery Limited” have the same legal form. What matters is the company type registered at Companies House, which you can check for free on the public register.

How a Private Limited Company Is Taxed

Because a private and limited company is a separate legal person, it is taxed separately from you. The company pays Corporation Tax on its profits. You then pay personal tax only on what you take out, usually as salary or dividends. A sole trader has no such split: all the business profit is taxed as their own income through Self Assessment.

Tax	Rate or allowance	Applies to
Corporation Tax, small profits rate	19%	Company profits of £50,000 or less
Corporation Tax, main rate	25%	Profits over £250,000, with marginal relief in between
Dividend allowance (2026/27)	£500	Dividends you receive personally
Dividend tax (2026/27)	10.75% / 35.75% / 39.35%	Basic / higher / additional rate

Sources: GOV.UK, Corporation Tax rates and GOV.UK, Tax on dividends, checked October 2026.

The paperwork is heavier too. GOV.UK’s guidance on running a limited company lists annual accounts, a Company Tax Return and company records among a director’s duties. Directors stay legally responsible even if an accountant does the work, and failures can lead to fines, prosecution or disqualification. Our guide to accounts and tax returns for private limited companies covers those filings in more detail.

Which Company Type Fits You? A Quick Checklist

Not every business needs to become a private and limited company. Use these five questions to narrow down the right structure.

Answer yes or no

Do you want your personal assets kept separate from business debts?
Are you comfortable filing annual accounts and a Company Tax Return?
Will you bring in co-owners or investors through shares?
Is your organisation a club, charity or not-for-profit with no shareholders?
Do you plan to sell shares to the general public?

Yes to 1–3: a private company limited by shares is the usual fit. Yes to 4: look at a company limited by guarantee. Yes to 5: only a plc can do this. No to 1 and 2: staying a sole trader may suit you better for now.

Example Scenario (illustrative)

Priya runs a small bakery in England with a profit of £40,000 and no other income. She compares staying a sole trader with becoming a private and limited company that pays out everything left after Corporation Tax as dividends in 2026/27.

Step	Sole trader	Private limited company
Business tax	None at business level	Corporation Tax: £40,000 × 19% = £7,600
Personal tax	Income Tax: £27,430 × 20% = £5,486.00 Class 4 NI: £27,430 × 6% = £1,645.80	Dividends of £32,400. After £12,570 Personal Allowance and £500 dividend allowance: £19,330 × 10.75% = £2,077.98
Total tax	£7,131.80	£9,677.98

Illustrative only, using 2026/27 GOV.UK rates. It ignores director salary, employer National Insurance, pension contributions, accountancy costs and payments on account.

In this simplified case, the company route costs Priya more tax. Real outcomes depend on how profit is drawn out, whether some is left in the company and other income, which is exactly why the decision deserves proper advice rather than a rule of thumb.

Reviewer’s View (Shamayun Chowdhury)

From a reviewer’s perspective, the most common misunderstanding is treating a private and limited company as a tax trick. Its real advantages are legal separation and a structure that suits growth or co-ownership. Whether it saves tax depends on profit levels and how money is taken out, so run the numbers for your own figures before you incorporate.

Common Mistakes

Mistake	Why it happens	Possible consequence	How to avoid it
Adding “Ltd” to a name without registering	It looks more professional	Misleading customers and no liability protection at all	Only use “Ltd” once Companies House has registered the company
Assuming limited liability covers everything	Not reading loan or lease terms	Personal liability under a personal guarantee	Check what you sign personally
Treating company money as your own	Habits carried over from sole trading	Tax and record-keeping problems	Take money only as salary, dividends or a recorded director’s loan
Thinking “private” means hidden	Confusing share ownership with secrecy	Surprise that details appear on the public register	Expect your company and director details to be public

Private Limited Company FAQs

Is a private limited company the same as a limited company?

Not always. Most limited companies in the UK are private companies limited by shares, so the terms are often used interchangeably. But a public limited company (plc) is also limited, and a private company can be unlimited. The company type registered at Companies House is what counts.

What is a private liability company?

“Private liability company” is usually a mix-up of private limited company. It means a company that cannot sell shares to the general public and whose members’ liability is limited, typically to any amount unpaid on their shares. The UK has no separate legal form called a private liability company.

Can one person run a private limited company?

Yes. A company limited by shares needs at least one shareholder, and that person can also be the director. Many small UK companies are run by a single shareholder-director who owns all the shares and makes all the decisions.

Can a private limited company sell shares to the public?

No. A private company cannot offer its shares for sale to the general public. It can still issue shares privately, for example to co-founders, family or chosen investors. Only a public limited company may offer shares to the public.

What does Ltd mean after a company name?

Ltd is the short form of Limited. It shows the business is a private company whose members have limited liability. Companies House accepts either Limited or Ltd as the ending, and companies with a registered office in Wales may use Cyfyngedig or Cyf instead.

Is a private limited company better than being a sole trader?

It depends on your circumstances. A company keeps business debts separate from your personal assets and suits growth or co-ownership, but it brings extra filings and does not always cost less tax. Compare both routes on your own figures and take professional advice before deciding.

Are private limited company details public?

Yes. Private refers to who can buy the shares, not secrecy. A company’s registered details, including its directors and filed accounts, appear on the public Companies House register, which anyone can search free of charge.

Private and Limited Company: Choosing the Right Label for Your Business

If you register a company limited by shares, the correct description is “private limited company”. On your website or letterhead, the registered name ending in “Ltd” or “Limited” already tells readers what they need to know. Describing yourself as a private and limited company is accurate, but you should never use either word if the business is not registered that way.

If you are still a sole trader, use your own name or a trading name with no “Ltd”. Should you later incorporate, update invoices, contracts and bank details so they show the new company name and number.

Final Verdict: Private and Limited Company

A private and limited company is usually one and the same thing: a private company limited by shares, ending in “Ltd”. The words still mean different things. “Private” stops shares being sold to the public; “limited” caps the owners’ liability. Check the tax and paperwork before choosing it over sole trading.
