What Is Companies House and Why Does It Matter?
Companies House is the UK government agency responsible for incorporating and dissolving limited companies, as well as registering company information. It operates under the Department for Business and Trade and plays a critical role in maintaining the official register of companies in England, Wales, Scotland, and Northern Ireland.
Every limited company and limited liability partnership (LLP) must register with Companies House when they start trading. Once registered, companies must submit certain information regularly, which becomes public record. This transparency helps protect consumers, creditors, and other businesses by providing access to vital company data.
Company Registration and Filing Requirements
When you set up a limited company or LLP, you need to register your business with Companies House. Registration involves providing details such as your company name, registered office address, director(s), and share structure (for limited companies). This process can be completed online, usually within 24 hours, for a fee of £12.
After registration, businesses must meet ongoing filing requirements to stay compliant. Failure to file on time can lead to penalties, prosecution, or even compulsory strike-off.
Key Filing Obligations
- Annual Confirmation Statement: Must be filed at least once every 12 months to confirm or update company information. The fee for filing is £13 online or £40 by post.
- Annual Accounts: Financial statements must be filed within nine months of the company’s financial year-end. These accounts provide transparency about your company’s financial performance and position.
- Event-Driven Filings: Any changes such as appointment or resignation of directors, change of registered office, or allotment of shares must be notified promptly.
You can submit most filings online through the Companies House WebFiling service or by using third-party software.

What Information Does Companies House Hold?
Companies House holds a wide range of information about registered companies, all of which is accessible to the public. This allows potential customers, suppliers, investors, and other stakeholders to check company details before making decisions.
The information publicly available includes:
- Company name, number, and registered office address
- Details of company directors and secretaries
- Shareholders and share capital structure (for limited companies)
- Annual accounts and financial reports
- Filing history, including confirmation statements and event-driven filings
- Company status (active, dissolved, dormant, etc.)
All these details can be searched and viewed free of charge on the Companies House Service website, which is an invaluable tool for due diligence and competitor research.
How to Use the Companies House Search Tool
The Companies House Service provides an easy-to-use online search tool that allows you to find detailed information about any registered company in the UK. Access it via GOV.UK’s Companies House page.
To use the search tool effectively, you can look up companies by their name or registration number. The search results provide a summary of the company’s key details, filing history, and downloadable documents such as annual accounts and confirmation statements.
This tool is particularly useful for:
- Checking the legitimacy of a potential supplier or customer
- Verifying director appointments and company status
- Researching competitors or potential business partners
- Monitoring your own company’s filings and status
The Importance of Compliance and Penalties for Late or Incorrect Filings
Staying compliant with Companies House filing requirements is not just a legal obligation but also vital for maintaining your company’s reputation and good standing. Late or incorrect filings can attract penalties, which increase the longer you delay.
For the 2026/26 period, the penalties are as follows:
- £150 if your accounts are up to 1 month late
- £375 if 1 to 3 months late
- £750 if 3 to 6 months late
- £1,500 if more than 6 months late
These fines apply each time accounts are late and can be compounded if multiple years are missed. In severe cases, persistent non-compliance can lead to criminal prosecution against directors and compulsory strike-off of the company.
To avoid penalties, use reminders to track filing deadlines and consider using accounting software or professional advice to prepare and file documents accurately and on time.
