Registering a new company at Companies House in the UK involves creating a legally recognised business entity by submitting company details, appointing directors, choosing ownership arrangements, preparing formation documents and completing the registration process.
Once approved, your company receives a Certificate of Incorporation and becomes legally separate from the people who own it.
For most first-time founders, the process is more straightforward than expected when completed in the correct order. Understanding what information is required before applying can help you avoid delays, corrections and unnecessary costs later.
Key takeaways:
- A limited company is legally separate from its owners
- You must register before starting business activities
- Most UK businesses register as companies limited by shares
- Directors remain legally responsible for compliance and records
- Corporation Tax responsibilities begin when business activity starts
This guide explains exactly how to register a new company at Companies House in the UK, what documents you need, how much it costs and what happens after approval.
What Does It Mean to Register a New Company at Companies House?
Registering a new company at Companies House means creating a legally recognised business entity in the UK. Once registered, your company becomes separate from you personally, allowing it to own assets, enter contracts and operate under its own legal identity.
For most founders, registration means forming a private limited company (Ltd). This structure limits personal liability to the amount invested into the company rather than making owners personally responsible for unlimited business debts.
A company director manages the business and remains legally responsible for filings, records and compliance. Although accountants or advisers can help with administration, responsibility stays with directors.
Not every business must register with Companies House. Sole traders and some partnership structures follow different rules. Registration also creates public company records, while certain personal information remains protected under UK company law.
Is a Private Limited Company the Right Business Structure for You?
Before you register, it is worth deciding whether a private limited company matches how you plan to operate. A limited company offers legal separation, stronger credibility and potential funding opportunities. However, it also creates additional reporting and compliance duties.
If your aim is long-term growth, investment and structured ownership, incorporation may make sense. If simplicity matters more, another structure may suit you.
| Structure | Ownership | Liability | Tax Position | Administration |
| Limited Company | Separate legal entity | Limited | Corporation Tax | Higher |
| Sole Trader | Individual | Unlimited | Income Tax | Lower |
| Partnership | Shared | Shared | Personal taxation | Moderate |
A limited company may suit you if:
- You want personal liability protection
- You expect business growth
- You want to attract investors
- You plan to retain profits inside the company
It may not suit you if:
- You want minimal administration
- You prefer simpler annual reporting
- You are testing a short-term business idea
Many founders begin as sole traders and later incorporate, while others register immediately to establish credibility from day one.
Which Type of Limited Company Should You Choose Before Registration?
Before starting registration, decide which limited company model supports your goals.
What Is a Company Limited by Shares?
A company limited by shares is the most common UK company structure. Ownership is divided into shares and shareholders receive rights connected to those shares. Profits are commonly distributed through dividends.
This structure usually suits businesses aiming to generate profit.
Typical characteristics include:
- Ownership through shareholders
- Ability to issue shares
- Potential dividend payments
- Voting rights linked to ownership
A single person can:
- Own 100% of shares
- Act as sole director
- Operate the company independently
One formation guide explained:
“Registering with Companies House is a relatively simple process in theory, but registrations are often rejected or delayed for minor oversights or errors in the application.”
That practical reminder reflects why planning your ownership structure early matters. A shareholder holding more than 25% of ownership or voting rights may qualify as a Person with Significant Control (PSC).
What Is a Company Limited by Guarantee?
Companies limited by guarantee usually operate for non-profit purposes. Instead of shareholders, guarantors agree to contribute a fixed amount if the company cannot meet debts.
This structure commonly appears in:
- Community organisations
- Membership bodies
- Some charitable activities
Typical features include:
- No traditional share ownership
- Profits generally reinvested
- Liability capped to guaranteed amount
Many organisations set guarantee values at a low level, such as £1. Choosing the correct structure early reduces amendments later and makes registration more straightforward.
How Do You Choose a Company Name That Meets Companies House Rules?
Your company name creates the first impression, but it must also satisfy legal requirements. The name cannot duplicate an existing registered company and cannot be misleadingly similar to another business or trade mark. Most private limited companies must include Limited or Ltd.
Your name must not:
- Be offensive
- Suggest government approval without permission
- Include restricted expressions without approval
- Closely imitate another registered company
Companies House may challenge names considered “too like” existing businesses. You may also trade under a separate business name, but additional restrictions apply.
A competitor guide summarised the practical risk:
“If you don’t check that your business name follows these rules and go ahead with the name, you may breach a trademark and be required to change your business name.”
Good naming decisions reduce delays and protect future branding.
What Information and Documents Do You Need Before Registering?
Preparation reduces registration mistakes. Before beginning the application, gather all required company details.
You generally need:
- Registered office address
- Registered company email address
- Director details
- Service addresses
- Shareholder or guarantor information
- Company ownership structure
- SIC code
- Identity verification details where required
Your registered office must:
- Be a physical UK address
- Match the company’s registration jurisdiction
- Receive official correspondence reliably
The email address supplied is not publicly displayed but must remain monitored.
You should also prepare constitutional documents including:
- Memorandum of Association
- Articles of Association
- Statement of Capital or Guarantee
If registering online, some documents are created automatically during submission. Preparing everything before starting reduces interruption during the application process.
Who Can Be a Director, Shareholder, Company Secretary or PSC?
Before you register your company, you need to understand who can legally hold each role and what responsibilities come with it. These positions can overlap in many private limited companies, especially where one person starts and runs the business alone.
A common first-time founder question is whether one person can do everything. In many cases, yes, one person may act as director, shareholder and PSC at the same time.
What Are a Director’s Legal Responsibilities?
Every private limited company must have at least one director. A director must be at least 16 years old and must not be disqualified from acting as a company director. Directors are legally responsible for running the company and ensuring reporting obligations are completed correctly.
Key responsibilities include:
- Maintaining company records
- Filing annual accounts
- Submitting tax returns
- Confirming Companies House information remains accurate
- Acting according to company rules
- Keeping financial records
Even if accountants or advisers assist, legal responsibility remains with directors.
One industry guide explained:
“You can hire other people to manage your accounts, but you’ll still be legally responsible for all company records and accounts.”
That principle often surprises new founders and is one of the most important obligations to understand before incorporation.
Do You Need a Company Secretary?
For a private limited company, appointing a company secretary is optional. Some businesses still appoint one to support administration and compliance.
A company secretary may help with:
- Maintaining statutory records
- Coordinating filings
- Organising company meetings
- Supporting governance processes
However:
- They cannot replace director responsibility
- Certain individuals may face eligibility restrictions
- Directors remain accountable regardless of delegation
Many small companies operate successfully without appointing one.
Who Counts as a Shareholder or Person With Significant Control?
A company limited by shares must have at least one shareholder.
Shareholders may:
- Own part or all of the company
- Vote on company decisions
- Receive profits through dividends
A Person with Significant Control (PSC) is generally someone who:
- Holds more than 25% of shares
- Controls more than 25% of voting rights
- Has significant influence over the company
In a one-person company, you may simultaneously be:
- Sole director
- Sole shareholder
- Sole PSC
Understanding ownership and control early makes registration smoother and helps avoid corrections later.
How Do You Prepare the Required Company Formation Documents?
Company registration requires a small set of legal formation documents that define how your company exists and operates. The two most important documents are the Memorandum of Association and the Articles of Association. The memorandum confirms that founding members agree to form the company.
You generally need:
- Memorandum of Association
- Articles of Association
- Share information or guarantee details
- Ownership information
- Subscriber details
If registering online:
- The memorandum is normally generated automatically
- You can adopt standard model articles
If registering by post:
- Documents may need preparing manually
For companies limited by shares, details form part of the statement of capital. For companies limited by guarantee, details form part of the statement of guarantee.
These documents create the operational framework that governs how your company functions after incorporation.
How Do You Register a New Company at Companies House Step by Step?
Once you have chosen your company structure, prepared your documents and gathered the required information, the next stage is completing the official registration process with Companies House.
Although company formation may seem technical at first, the application follows a clear sequence and can usually be completed smoothly when each requirement is prepared in advance.
The process involves verifying identities where required, providing company and ownership details, confirming legal documents and submitting your application for approval. Following the steps in order can help reduce delays and avoid common registration mistakes.
Follow this step-by-step process to register your new company at Companies House in the UK:
Step 1: Verify Your Identity (If Required)
Before starting your company registration, you may need to complete identity verification through the relevant Companies House process. Once verified, you’ll receive a personal code that may be required during registration.
If your company has multiple directors, each director may need their own verified identity details.
Step 2: Create Your Government Gateway Account
You’ll need to create a Government Gateway user ID and password for your business if you do not already have one. This account allows you to access company and tax-related services after registration.
Step 3: Start Your Companies House Application
Begin the online company registration process and select the appropriate company structure based on how your business will operate.
Step 4: Enter Your Company Details
Provide the essential information needed to create your company record, including:
- Company name
- Registered office address
- Registered email address
- Standard Industrial Classification (SIC) code to describe business activities
Step 5: Add Directors and People with Significant Control (PSC)
Enter details for company directors and confirm ownership and control information.
This typically includes:
- Director details
- Service addresses
- PSC declarations
- Ownership or voting rights information
Step 6: Add Shareholders or Guarantors
Depending on your company type, provide details of the people who own or support the business.
Include:
- Shareholder information and ownership percentages (for companies limited by shares)
- Guarantor information and guarantee amounts (for companies limited by guarantee)
Step 7: Confirm Your Company Formation Documents
Review and approve the documents that define how your company operates.
This may include:
- Memorandum of Association
- Articles of Association
- Statement of Capital or Guarantee
You can usually use standard model articles or upload customised versions if required.
Step 8: Submit Payment and Complete Registration
Pay the registration fee and submit your application to Companies House for review.
Once approved, you’ll receive:
- Certificate of Incorporation
- Official company number
- Company formation date
After your Certificate of Incorporation is issued, your company officially exists as a separate legal entity in the UK.
How Much Does It Cost to Register a Company at Companies House in 2026?
Registration costs vary depending on how you apply. For most founders, online registration is the fastest route.
| Registration Method | Fee | Typical Processing |
| Online Registration | £100 | Usually within 24 hours |
| Postal Registration | £124 | Around 8–10 working days |
| Formation Agent | Varies | Depends on package |
| Third-Party Software | Varies | Depends on provider |
Professional services may include:
- Address services
- Compliance support
- Formation documents
- Tax setup assistance
Price should not be the only deciding factor. If your structure is straightforward, direct registration can work well. If ownership, tax or governance is more complex, professional support may reduce corrections and delays.
What Happens After Your Company Is Registered?
Receiving incorporation approval is the beginning of your obligations, not the end. Your next actions depend on whether the company starts trading immediately.
When Do You Need to Set Up Corporation Tax?
If your company begins doing business activities, Corporation Tax administration becomes important.
Business activity may include:
- Buying goods
- Selling services
- Advertising
- Employing people
- Renting property
You may need:
- Business Tax Account access
- Company UTR
- Corporation Tax activation
Even loss-making companies generally still have filing obligations.
When Do VAT and PAYE Rules Apply?
Not every company registers immediately. VAT registration becomes relevant when legal thresholds apply or where voluntary registration benefits the business.
PAYE becomes relevant if:
- You employ staff
- You pay yourself as director through payroll
Additional responsibilities may include:
- Payroll operation
- National Insurance
- Workplace pensions
What Records Must You Keep After Incorporation?
Record keeping remains a core director responsibility.
Maintain:
- Accounting records
- Company decisions
- Share information
- Tax records
- Loan records
- Transaction documentation
One guide highlighted the importance clearly:
“All records need to be kept for a minimum of six years.”
Good records reduce compliance risks and make future growth easier.
What Legal and Tax Responsibilities Continue After Registration?
Once your company is incorporated, ongoing compliance becomes part of running the business. Registration creates legal obligations that continue whether the business is actively trading or temporarily dormant.
As a director, you remain responsible for ensuring deadlines are met and records stay accurate.
Your continuing responsibilities may include:
- Filing annual accounts
- Submitting Corporation Tax returns
- Sending confirmation statements
- Keeping company information updated
- Maintaining accounting records
- Reporting changes to directors or shareholders
If your company becomes dormant, filing duties may still apply. Tax responsibilities can also expand depending on how the company operates.
You may need to consider:
- Corporation Tax
- VAT registration
- PAYE obligations
- Dividend administration
Failing to meet requirements can lead to penalties, late filing charges and, in serious cases, company removal from the register. Treat compliance as an ongoing business process rather than a yearly task.
What Common Mistakes Delay or Reject a Companies House Application?
Many registration delays happen because of small avoidable errors rather than complex legal problems. Submitting complete and accurate information the first time improves approval speed.
Common mistakes include:
- Choosing a company name that conflicts with existing registrations
- Entering an unsuitable registered office address
- Providing incorrect director information
- Missing ownership details
- Selecting the wrong company structure
- Uploading incomplete formation documents
- Using incorrect share allocations
- Failing identity verification requirements
Applications can also be delayed if:
- Information is inconsistent across forms
- Articles of association contain errors
- Shareholder details do not align
A practical approach is to review every section before submission. You can present the final checklist in a cleaner, more scannable table format like this:
Final Pre-Submission Checklist
Before submitting your Companies House application, review each item below to reduce the risk of delays, corrections or rejection.
| Checklist Item | What to Confirm |
| Company name verified | Confirm the name follows Companies House rules and is not already registered or too similar to an existing company |
| Registered address confirmed | Check that your registered office is a valid UK physical address and meets official requirements |
| Director details checked | Review director information, service addresses and identity requirements where applicable |
| Share structure reviewed | Confirm share ownership, share allocation and PSC details are accurate |
| Documents complete | Ensure all formation documents and supporting information are prepared before submission |
Completing this checklist before applying can help make your company registration process smoother and reduce avoidable delays. Preventing errors is usually faster than correcting them after filing.
Can You Register a Company Yourself or Should You Use an Agent?
There is no single correct approach. Your decision depends on complexity, confidence and the level of support you want. Many founders register directly, while others prefer professional guidance.
| Option | Best For | Advantages | Considerations |
| Register Yourself | Simple company setup | Lower cost, full control | Requires preparation |
| Formation Agent | First-time founders | Guided process | Additional fees |
| Accountant Support | Tax planning | Broader advice | Higher overall cost |
| Software Services | Digital setup | Convenience | Features vary |
Registering yourself may suit you if:
- Ownership is straightforward
- You understand company responsibilities
- You want lower startup costs
Using an agent may suit you if:
- Multiple owners are involved
- You want support with compliance
- You prefer faster administration
Professional help does not remove legal responsibility, but it can reduce avoidable mistakes.
What Should You Remember Before You Register Your New Company?
Before submitting your application, focus on getting the foundations right. Companies House registration is not simply an administrative step, it establishes the legal framework for how your business operates.
Remember to confirm:
- Your business structure suits your goals
- Your company name follows the rules
- Directors understand their responsibilities
- Ownership details are correct
- Your registered office is appropriate
- Your documents are prepared
- Tax and compliance responsibilities are understood
You do not need to begin trading immediately after incorporation. Some companies remain dormant until they are ready to operate. If this is your first company, aim for clarity rather than speed. Taking extra time before registration is usually easier than changing details later.
Conclusion
Registering a new company at Companies House in the UK is a structured process that becomes much easier when completed in the right order. Start by choosing the correct business structure, prepare your legal and ownership details, select a compliant company name and complete registration carefully.
For most founders, a company limited by shares offers the most practical route, but every business should be evaluated based on ownership, risk and future plans.
Once incorporated, remember that registration is only the beginning. Your responsibilities continue through record keeping, tax management and ongoing filings.
If you approach company formation with preparation and accurate information, you can create a strong foundation for sustainable growth and long-term business confidence.
