How to Incorporate a Company in UK : A Simple Step-by-Step Guide (2025)

Table of Contents

You can set up a company in the UK in just 24 hours. The UK stands as one of the world’s most business-friendly countries. Its $3 trillion GDP makes it the 6th largest economy worldwide.

Local entrepreneurs and international business owners will find that UK company incorporation brings most important benefits. You need just one share to start – there’s no minimum capital requirement. The best part? You don’t even need UK residency to become a director.

Businesses find the UK’s 25% corporate tax rate and double tax treaties very attractive. The incorporation process through Companies House needs proper documentation and attention to detail.

This piece guides you through every step to incorporate your UK company. We cover everything from picking your company structure to finishing your after-setup tasks. Let’s begin with what you need to know.

Step 1: Decide if Incorporation Is Right for You

Starting a business in the UK comes with a crucial choice: should you set up a limited company? Let’s get into what incorporation means and see if it’s right for your business before you file any paperwork with Companies House.

What is incorporation of a company?

Registering a business as a limited company with Companies House is what we call incorporation ^[1]. This process turns your business into its own legal entity – making it a separate “person” under the law ^[1].

Your incorporated company stands on its own, unlike sole traders or partnerships. A legal wall exists between your personal life and business operations ^[1]. Your company can now:

Sign contracts under its own name
Have its own property and assets
Take legal action and be sued as a separate entity
Keep running whatever happens to ownership

This change affects how your business runs and your role as an owner or director. Most UK companies are limited liability companies, and members can limit their liability through shares or guarantee ^[1].

Benefits of incorporating a company in the UK

UK entrepreneurs choose to incorporate their businesses because it offers several valuable advantages:

Limited liability protection is the biggest reason people incorporate. Your personal finances stay separate from your business debts ^[2]. If your company runs into money problems or legal issues, your personal assets are safe up to your shares’ nominal value ^[3]. Your home, savings, and personal property remain protected if the business fails.

Tax efficiency makes incorporation attractive. UK limited companies pay corporation tax rates between 19% and 25% on profits ^[3]. Sole traders pay higher rates – 20-45% income tax (19-48% in Scotland) ^[3]. You can also be smart about taking money from the business as both director and shareholder by mixing salary and dividends ^[4].

Professional credibility comes with incorporation. Bigger organizations often prefer doing business with limited companies ^[2]. Having a company number and “Ltd” or “Limited” in your name opens new business doors ^[5]. Some industries, like IT, finance, and construction, require their suppliers to be incorporated ^[3].

Better funding options become possible. Limited companies can sell shares to raise money – something sole traders can’t do ^[2]. This lets you bring in investment without taking loans. Banks also look more favorably at limited companies for business loans ^[6].

Brand protection is automatic with incorporation. Your company name becomes yours legally. No other business can use your exact name or anything too close, especially in your industry ^[6].

When incorporation may not be the best option

Incorporation isn’t always the right choice for every business:

Administrative work is a big deal as it means that limited companies have stricter reporting rules than sole traders ^[2]. You’ll need to submit:

Annual accounts to Companies House
Company tax return to HMRC
Confirmation statements about company details
Required forms for any changes

This means spending lots of time or paying professionals to help ^[5].

Business information becomes public with incorporation. Anyone can see your company’s financial results, director details, and other business information through Companies House ^[3]. This openness builds trust but might not work if you want privacy.

Costs run higher than operating as a sole trader. You’ll pay £50 for standard online registration ^[1], plus higher accountancy fees because reporting is more complex ^[3].

Legal duties increase for company directors. You must act in the company’s interests, keep good records, and follow all rules ^[1]. Breaking these rules can lead to fines or losing your director status.

Small businesses with low profits and few assets might find incorporation creates extra work and costs without enough benefits ^[5]. Take time to look at your situation and future plans before you incorporate.

Step 2: Choose the Right Company Structure

Choosing the right company structure is a vital decision at the time of incorporating in the UK. Your choice sets your legal obligations, tax liabilities, and the way you’ll manage business assets. Here are the main options to help you make an informed decision.

Private limited vs public limited vs LLP

Private Limited Company (Ltd) stands as the UK’s most common business structure. Shareholders own it while directors manage it, and these can be the same people. The main advantage is limited liability—shareholders are only responsible for business debts up to the amount they’ve invested ^[7]. This structure gives you tax efficiency, and companies pay corporation tax at rates between 19-25% on profits ^[8].

A private limited company requires:

At least one director
At least one shareholder
A unique company name
A registered office address
Articles of association

Public Limited Company (PLC) needs a minimum share capital of £50,000 and at least two directors ^[9]. PLCs can sell shares to the public and list on stock exchanges, which makes them ideal for larger businesses looking for major investment. The trade-off is stricter reporting requirements and higher risk of hostile takeovers ^[9].

Limited Liability Partnerships (LLPs) blend partnership and limited company elements. An LLP is a separate legal entity from its members, giving limited liability protection while keeping the tax flexibility of a partnership ^[10].

In fact, LLPs are different from companies in taxation—members pay tax directly on their profit share as self-employed individuals, while the LLP pays no tax ^[11]. This structure needs:

At least two designated members
A partnership agreement
Registration with Companies House
A registered office address ^[2]

We used LLPs mostly for professional service firms like accountants and solicitors ^[8], though they work well for any business wanting partnership advantages with limited liability.

Limited by shares vs limited by guarantee

The choice between “limited by shares” or “limited by guarantee” shapes your company’s ownership, profit distribution, and business operations.

Limited by Shares remains the standard pick for commercial businesses. Under this structure:

Shareholders who buy shares own the company ^[1]
Shareholders can receive profits as dividends ^[1]
Liability stays limited to the amount paid (or unpaid) on shares ^[1]
Profit-making ventures where owners want personal income find this ideal ^[1]

A company limited by shares can have one shareholder (who can also be the director) owning the entire company, with no cap on shareholders ^[1]. Share value can be any amount—many companies pick £1 per share to keep potential liability reasonable.

Limited by Guarantee works differently with no shareholders or share capital. Instead:

Guarantors (members) control the company ^[1]
Members guarantee a fixed sum (usually £1) to contribute during insolvency ^[1]
The company keeps all profits rather than distributing them ^[1]
Non-profits, charities, and social enterprises prefer this structure ^[1]

This setup gives membership flexibility since it doesn’t tie to shares, so members can join or leave easily ^[1]. The setup process matches companies limited by shares, except you submit a statement of guarantee instead of capital ^[1].

Companies House guidelines state you can’t switch from a company limited by shares to one limited by guarantee (or vice versa) ^[1]. You’ll need to create a new company and close the existing one to change structure—a process that needs careful planning.

Your business goals should guide your choice: profit-generating businesses typically choose limited by shares, while non-profit organizations go for limited by guarantee ^[1].

Step 3: Pick a Unique and Compliant Company Name

Your company’s name is a vital part of incorporating your business in the UK. The name you pick shapes your business identity and needs to meet specific legal requirements. Let’s get into what makes a company name valid and how yours can meet all regulatory standards.

Companies House name rules and restrictions

Companies House has several basic rules every UK company name must follow. Note that your company name must be unique. It can’t be similar to any existing registered company name. This helps customers avoid confusion and protects businesses that are already running.

Private limited companies must end with “Limited” or “Ltd” (or Welsh equivalents “Cyfyngedig” or “Cyf” if registering in Wales) ^[6]. This suffix shows your business is a limited liability entity.

Your company name must follow these formatting rules:

No offensive language or content
Can’t begin with ‘www’
Must stay under 180 characters
No special characters, symbols, or punctuation in the first three characters
No suggestion of government or public authority links without permission

Companies House might reject names that break these rules. The number of rejections for potentially offensive names jumped from 351 in 2022 to 560 in 2024 ^[12], showing tighter enforcement of naming standards.

Sensitive words and expressions to avoid

Special approval is needed for sensitive words because they might mislead people or hint at business superiority, special status, or specific functions. These words fit into different categories:

The original list includes terms that suggest business superiority or official status like “British,” “Institute,” or “Association.” Words that hint at government connections such as “Parliament” or “Council” need approval too. Terms for regulated activities like “Banking” or “Insurance” also make the list ^[13].

You’ll need written permission from the right regulatory body or government department to use any sensitive word. This usually comes as a letter or email of non-objection that goes with your company registration application ^[14]. Your application won’t go through without this documentation.

UK law regulates more than 130 sensitive words and expressions. After law changes in 2015, some previously restricted words—like “Group,” “Holding,” “United Kingdom,” “European,” and “International”—no longer need special approval ^[14].

How to check name availability

You should check if your desired name is available before submitting incorporation papers. Companies House offers a free online name checker that searches their database of over 4 million registered companies ^[15].

This tool checks if your chosen name is free and spots possible conflicts with similar names. It also flags sensitive words that need approval. Results show up right away, so you’ll know quickly if your name works.

Companies House might still reject names that are “too like” existing companies, even if the exact name isn’t taken. They look at whether people might mix up the two businesses ^[16].

You can use a “trading name” if you want to operate under a different name than your registered one. Notwithstanding that, official documents and your website must clearly state it’s a trading name with something like “[Trading Name] is the trading name of [Official Company Name]” ^[16].

These guidelines will give a smooth incorporation process and help avoid delays or rejections because of name issues.

Step 4: Prepare the Required Documents

Your UK company’s incorporation starts with getting the right paperwork ready. The right documentation will give a smooth registration process with Companies House and build your company’s legal framework. Let’s get into the documents you need to incorporate your company.

Memorandum and articles of association

The memorandum of association is your company’s basic contract. This document shows that subscribers want to form the company and become its original members. Companies limited by shares use this document to prove members agree to take at least one share each ^[4].

You cannot change the memorandum’s prescribed format. Companies House will not accept applications with different wording ^[4]. The online registration system creates this document automatically when your application gets approved ^[17]. Paper registrations require you to use the official memorandum template that matches your company type ^[18].

Your company’s internal rulebook is the articles of association. This legally binding document explains how members and directors make decisions and handles share-related matters ^[4]. You can choose from three options:

Adopt model articles in their entirety
Use model articles with amendments
Create bespoke articles tailored to your company’s needs

The Companies Act 2006 provides model articles that most companies use ^[19]. You just need to check a box on your application if you’re using standard model articles ^[18]. Modified or bespoke articles need review during registration.

Form IN01 and statement of capital

Form IN01 has the most important details about your business. This vital document needs ^[4]:

Proposed company name
Registered office location (England/Wales, Wales, Scotland, or Northern Ireland)
Company type (private/public, limited by shares/guarantee, etc.)
Registered email address
Standard Industrial Classification (SIC) code describing business activities
Choice of articles of association

Online applications cost £50, while postal applications cost £71 through check payment to Companies House. Postal applications take 8-10 days ^[2]. Registration requires at least three personal details from you and other shareholders or guarantors – like town of birth, mother’s maiden name, or national insurance number ^[2].

Companies limited by shares must complete a statement of capital that shows the company’s issued share capital ^[5]. This statement needs:

Total number of issued shares
Share class(es)
Total number of issued shares in each class
Nominal value of each share class
Currency of share value
Rights attached to each share class

Details of directors, shareholders, and PSCs

The core team’s detailed information must be part of your application. Directors need to provide ^[4]:

Full names
Service addresses (business correspondence addresses)
Residential addresses (not publicly disclosed)
Date of birth (only month and year publicly visible)
Nationality
Occupation

Your application must identify persons with significant control (PSCs) – people who have substantial influence over your company. PSCs usually hold more than 25% of shares or voting rights, or can appoint/remove most directors ^[3].

Each PSC’s record must show:

Name and date of birth
Nationality and country of residence
Service address and residential address
Date they became a PSC
Nature of control, categorized by percentage brackets (over 25% up to 50%, more than 50% and less than 75%, or 75% or more) ^[3]

This information becomes public record, except residential addresses and full birth dates ^[20]. You can’t leave the PSC register empty – if PSC information isn’t available, you must explain why ^[3].

Step 5: Register with Companies House

The time has come to register your company with Companies House after preparing all your documents. This step is a vital part of starting a company in the UK, and you have two ways to submit your application.

Online vs paper registration methods

Digital registration gives you better advantages than paper submissions. The numbers tell the story – 99% of new companies now choose to register online ^[21]. The digital system’s built-in validation features make this a big deal as it means that only 8% of online applications get rejected, compared to 53% of paper submissions ^[21].

You can complete your application through the Gov.UK website if you choose the online route. Their digital platform lets you submit everything electronically and gives you instant confirmation with application tracking.

Paper registration still exists as an option through form IN01 by mail. This old-school method works but takes longer, costs more, and isn’t as convenient.

Companies House incorporation fees

Starting May 2024, UK company incorporation comes with specific costs ^[22]. Standard online registration costs £50 ^[10][22]. Paper registration runs higher at £71 ^[10][22].

Companies House charges extra for additional services beyond the simple registration. To cite an instance, an online confirmation statement costs £34, while paper submission jumps to £62 ^[10]. Electronic filing saves you money on almost every Companies House service.

How long the process takes

UK company incorporation speed depends on how you submit your application. Online applications usually wrap up within 24 hours ^[8][23], and many finish in just 8 hours ^[23].

Paper applications are nowhere near as quick – they typically need 8 to 10 days ^[24][2]. Applications that arrive late Friday afternoon might sit until Monday ^[23][9].

Your certificate of incorporation arrives once everything checks out. This document proves your company’s legal existence and shows your company number and formation date ^[2]. Most companies get automatic registration for Corporation Tax, unless they’re ‘dormant’ ^[2].

Step 6: What to Do After Incorporation

Your business owner’s trip starts right after you complete your company incorporation. You need to handle several significant administrative tasks that will build the foundation for your company’s operations.

Register for Corporation Tax and VAT

You must add Corporation Tax services to your business tax account as soon as you begin operations. This applies to activities like buying, selling, advertising, renting property, or employing staff ^[11]. The registration deadline is three months from when you start your business activities ^[25].

To register, you’ll need your:

Company registration number
Date you started doing business
Date your first accounts are made up to
10-digit Unique Taxpayer Reference (UTR) ^[11]

HMRC will send your Corporation Tax activation code within 10 days (21 days if abroad) along with instructions to activate the service ^[11].

Your business must register for VAT if your taxable turnover goes beyond £90,000 in one year or you expect to cross this threshold in the next 30 days ^[26].

Open a business bank account

A dedicated business bank account isn’t legally required, but it’s a smart move to keep your personal and business finances separate ^[27]. This makes your audit trail clear and helps you manage your finances better.

You’ll need these items to apply for a business account:

Your Companies House registration number
Personal details of all directors/partners (with 3-year address history)
Proof of identity and address ^[28]

UK’s major banks offer special accounts for new businesses. These accounts come with perks like free banking periods, accounting software integration, and business support services ^[28].

Set up accounting and reporting systems

UK law requires companies to maintain accurate financial records. You must keep all your financial documents, including invoices, receipts, wages, and other records for at least six years ^[1].

QuickBooks, Xero, FreshBooks, or FreeAgent are great accounting software options ^[1]. These tools automate your accounting tasks from invoicing to expense tracking and give you immediate insights into your financial status.

Good accounting systems help you meet your reporting requirements. These requirements include submitting annual accounts to Companies House, filing company tax returns with HMRC, and providing confirmation statements about your company information ^[1].

Conclusion

The UK’s business-friendly environment and straightforward incorporation process make starting a limited company an excellent choice for entrepreneurs and business owners. The advantages are significant.

A smooth transition into business ownership depends on how carefully you follow each step – from selecting your company structure to finishing post-incorporation tasks. You need to pay extra attention to detail, especially when you have to prepare documentation and register with Companies House.

On top of that, it helps to understand your ongoing responsibilities to stay compliant and build a strong foundation. Your business needs proper financial management, timely tax registrations, and regular updates to authorities.

Note that incorporation is just the beginning of your experience. Your success relies on keeping accurate records, meeting regulatory requirements, and adapting to changing business regulations.

Proper planning and execution of each step will help you establish your company the right way from day one. The time you invest in proper incorporation will give you protected personal assets, tax benefits, and improved business credibility.
