Registering a company with Companies House is the official process of incorporating a limited company in the UK. In 2026, the process is primarily completed online through GOV.UK, typically costs £100, and can often be approved within 24 hours if all information is submitted correctly.
Before applying, you must choose a company name, appoint directors, provide a registered office address, select SIC codes, and complete identity verification requirements.
Key points:
- Companies House registration creates a separate legal entity.
- Identity verification is now a critical part of the process.
- You need at least one director and one shareholder.
- Most applications are submitted online through GOV.UK.
- Successful registration results in a Certificate of Incorporation.
What Does It Mean to Register with Companies House?
Registering with Companies House means legally incorporating your business as a limited company in the United Kingdom. Once registered, your company becomes a separate legal entity from its owners, allowing it to enter contracts, own assets, and incur liabilities independently.
Unlike sole traders, limited companies must appear on the public Companies House register. Details such as the company name, registered office address, directors, and filing history become publicly accessible.
The registration process is managed by Companies House, while tax obligations are handled separately through HMRC. Although incorporation and taxation are connected, they are not the same process.
“Accurate company information at the point of incorporation significantly reduces registration delays and compliance issues later.” — Companies House Compliance Guidance
For many entrepreneurs, incorporation provides greater credibility, improved growth opportunities, and enhanced protection of personal assets.
Do You Need to Register with Companies House or Can You Operate as a Sole Trader?
Many new business owners wonder whether they should remain a sole trader or form a limited company. The answer depends on your goals, income level, risk exposure, and future plans.
Sole Trader vs Limited Company: Key Differences
Understanding the distinctions between these business structures can help you make an informed decision.
| Factor | Sole Trader | Limited Company |
| Legal Status | Individual | Separate legal entity |
| Liability | Personal liability | Limited liability |
| Taxation | Income Tax | Corporation Tax |
| Public Records | Private | Publicly available |
| Administrative Requirements | Lower | Higher |
As a sole trader, you retain complete control but also carry full responsibility for debts and obligations. A limited company separates personal and business finances, which can offer greater protection.
When Registering a Limited Company Makes Sense
While every business is different, there are several situations where incorporating with Companies House may offer clear advantages.
A limited company may be suitable if:
- Your business revenue is growing steadily.
- You plan to hire employees.
- You want to attract investors.
- You wish to establish greater credibility with clients.
- You want legal separation between personal and business assets.
For example, a freelance consultant earning modest income may initially operate as a sole trader, while a technology startup seeking investment will often benefit from incorporation at an earlier stage.
Ultimately, the right structure depends on both current circumstances and long-term objectives.
What Information and Documents Do You Need Before Registering a Company?
Preparation is one of the most important stages of company formation. Gathering accurate information before starting your application helps avoid delays and rejection.
Company Details You Must Prepare
Before submitting your application, you’ll need several key pieces of company information.
Required details include:
- A unique company name
- Registered office address
- Business activity SIC code(s)
- Share allocation details
- Memorandum of Association
- Articles of Association
People Involved in the Registration
Companies House requires information about the individuals who own or control the company.
These typically include:
- Company directors
- Shareholders (also known as subscribers)
- Persons with Significant Control (PSCs)
All names, dates of birth, addresses, and nationalities must be entered accurately and consistently throughout the application.
Identity Verification Requirements in 2026
Recent regulatory reforms have strengthened identity verification requirements. Directors and PSCs are generally expected to verify their identity through approved GOV.UK systems. This measure helps improve transparency and reduce fraudulent company registrations.
Essential Registration Information:
| Requirement | Purpose |
| Company Name | Identifies the business |
| Registered Office | Official correspondence address |
| SIC Code | Describes business activities |
| Directors | Manage company operations |
| Shareholders | Own company shares |
| PSC Information | Identifies significant control |
| Identity Verification | Confirms legitimacy |
Having these details prepared in advance can make the registration process significantly smoother.
How Do You Register with Companies House Online Step by Step?
Registering a company with Companies House online is generally a straightforward process when you prepare your details in advance.
Before starting, make sure you have information about your company structure, directors, shareholders, registered office address, and business activities ready.
Step 1: Create or Sign in to Your GOV.UK One Login Account
The first step is creating a GOV.UK One Login account or signing in to an existing account. This account gives you access to the Companies House online incorporation service and allows you to complete and manage your application securely.
Estimated time: 5–10 minutes
Step 2: Check Your Company Name Availability
Search for your preferred company name to confirm it is available and follows Companies House naming guidelines. Choosing a unique and compliant name helps avoid delays or rejected applications later in the process.
Estimated time: Around 5 minutes
Step 3: Enter Your Company Information
You will now need to provide important details about your business. Make sure all information is accurate, as errors can delay the registration process.
Include details such as:
- Company type
- Registered office address
- Company name
- Business contact details
- Trading information (if applicable)
Estimated time: 15–20 minutes
Step 4: Add Directors, Shareholders, and PSC Information
Next, provide details for everyone involved in owning or managing the company. Companies House requires information about directors, shareholders, and People with Significant Control (PSCs) for transparency and compliance purposes.
This usually includes:
- Director information
- Shareholder details
- PSC information
- Service addresses
Estimated time: 10–15 minutes
Step 5: Choose SIC Codes and Confirm Share Structure
Select the SIC codes that best describe your business activities. You will also need to confirm how ownership is divided and how company shares will be allocated among shareholders.
This section typically includes:
- SIC code selection
- Share allocations
- Ownership percentages
- Share classes (if applicable)
Step 6: Complete Identity Verification Checks
Some applications may require identity verification or additional checks before submission. Completing this step correctly helps Companies House verify that the information provided is accurate.
Estimated time: Varies depending on verification requirements
Step 7: Review, Submit, and Pay the Registration Fee
Before submitting your application, carefully review every section to ensure all details are correct. Once satisfied, pay the registration fee and submit your application for processing.
Estimated time: Around 5 minutes
What Happens After You Submit?
Once approved, Companies House will issue your Certificate of Incorporation, which confirms your company has been legally formed. Most online applications are processed within 24 hours, although additional checks may increase processing times in some cases.
How Much Does It Cost to Register with Companies House in 2026?
Registration costs can vary depending on how you choose to incorporate. Direct online registration through GOV.UK currently costs approximately £100, while third-party formation agents may charge additional fees depending on the services included.
Many formation providers offer packages that include registered office services, compliance support, digital documents, and business banking assistance.
Typical Company Formation Costs:
| Service | Estimated Cost |
| GOV.UK Online Registration | £100 |
| Registered Office Service | £30–£150 annually |
| Company Formation Package | £20–£100+ |
| Business Address Service | £40–£200 annually |
Although budget is important, entrepreneurs should focus on accuracy and compliance rather than selecting the cheapest option available.
What Are the Most Common Reasons Companies House Rejects Applications?
Application rejections are more common than many first-time business owners realise. Fortunately, most errors are preventable.
Company Name and Documentation Errors
Companies House frequently rejects applications due to naming issues or incomplete documentation.
Common examples include:
- Company names already in use
- Names containing restricted or sensitive words
- Inconsistent naming across documents
- Missing signatures
- Incorrect incorporation forms
Director, Shareholder, and PSC Issues
Personal information errors can also cause delays.
Typical problems include:
- Incorrect dates of birth
- Misspelled names
- Identity verification failures
- Inaccurate PSC information
- Ineligible directors
“The majority of rejected applications involve simple data-entry mistakes that applicants could avoid through careful review before submission.” — Companies House Registration Team
Reviewing every section thoroughly before submission significantly increases the likelihood of approval.
What Happens After Your Company Registration Is Approved?
Receiving approval is only the beginning of your company’s compliance journey. Once incorporated, Companies House issues your Certificate of Incorporation. This document serves as official proof that the company legally exists.
Most businesses then proceed with opening a business bank account, organising bookkeeping systems, and setting up accounting processes.
You will also receive an authentication code that enables access to Companies House online services, including WebFiling. Many new directors mistakenly believe registration completes all legal obligations. In reality, several ongoing filing responsibilities begin shortly after incorporation.
Proper organisation during the first few months helps establish strong compliance practices and prevents future administrative problems.
What Ongoing Responsibilities Do Limited Companies Have After Registration?
Registering your company is only the beginning. Once incorporated, limited companies must meet ongoing legal, financial, and reporting obligations to remain compliant and avoid penalties.
Annual Filing and Reporting Requirements
Every limited company must complete regular filings and maintain accurate records throughout the year. Missing deadlines can result in financial penalties or, in serious cases, company dissolution.
Common filing responsibilities include:
- Confirmation Statement: Confirm company details and ownership information remain accurate.
- Annual Accounts: Submit financial statements to Companies House each year.
- Corporation Tax Obligations: Register for Corporation Tax and file tax returns with HMRC.
- Statutory Record Maintenance: Keep records relating to directors, shareholders, and company decisions.
Staying organised and monitoring filing deadlines can help prevent compliance issues and unnecessary costs.
Maintaining Accurate Company Information
Company directors are responsible for ensuring Companies House records remain accurate and updated whenever changes occur.
You usually need to notify Companies House when there are changes to:
- Director appointments or resignations
- Registered office address
- Shareholder information
- People with Significant Control (PSCs)
- Company name changes
- Share allocations or ownership structure
Accurate record keeping helps maintain transparency and ensures your company remains legally compliant.
“Good corporate governance starts with maintaining accurate records and meeting filing deadlines consistently.” — UK Corporate Governance Adviser
Remaining compliant protects your company’s reputation, reduces regulatory risks, and supports long-term business growth.
How Can You Register with Companies House Successfully and Avoid Future Compliance Problems?
Registering with Companies House successfully requires careful preparation and ongoing compliance. Before submitting your application, ensure your company name is available, personal details are accurate, and the correct SIC codes are selected.
Completing identity verification promptly can also help prevent delays. After incorporation, maintain accurate company records and create a compliance calendar to track important filing deadlines, such as annual accounts and confirmation statements.
While many businesses register directly through GOV.UK, professional advisers or formation agents can provide valuable support. Staying organised and compliant helps protect your company and supports long-term business growth.
Conclusion
Understanding how to register with Companies House is an essential step for anyone starting a limited company in the UK. By preparing the required information, completing identity verification, and following the registration process carefully, you can avoid common mistakes and secure approval quickly.
Once incorporated, staying on top of filing obligations and compliance requirements will help keep your business in good standing and support its long-term success.
