How to Check if a Company Is Registered in the UK
Search the company by its registered legal name or company number. A matching Companies House record lets you confirm that the legal entity is recorded on the UK company register and review the identifying details attached to that record.
If several similar names appear, use the company number, registered office, incorporation date and current status to identify the correct entity. If you need to find the company first, use our UK company search.

What you can verify
Key UK Company Registration Details to Check
A registration check is most useful when you review several identifiers together rather than relying on the company name alone.
Company Number
The Companies House registration number is a key identifier for a registered company and helps distinguish businesses with similar names.
Company Status
Review the current status shown on the company record, such as active, dissolved or another statutory status returned by Companies House.
Incorporation Date
Check when the company was incorporated to help confirm that you are viewing the expected legal entity.
Registered Office
Compare the public registered office address with the business information you already have.
Company Type
See the legal company type recorded for the entity, providing additional context about the registered organisation.
Registered Business Activities
Review SIC codes where available to understand the nature of business activities recorded for the company.
What Is a UK Company Registration Number?
The company number is assigned when a company is incorporated and is used to identify that legal entity on the Companies House register. It is more reliable than a company name when you need to distinguish between similarly named businesses.
When you already have the number, enter it directly into the search tool. For a dedicated explanation of formats and number-based searches, see our company number search page when it becomes available.

What a Companies House Registration Does — and Does Not — Tell You
The legal entity is recorded on the company register
A matching record helps confirm the registered company name, company number and other public corporate details attached to that entity.
Registration alone is not proof that a business is trustworthy
A company appearing on the register should not be treated as a guarantee of financial strength, trading conduct or the accuracy of every item filed. Review the wider public record and use additional checks where appropriate.
Registration Information from Companies House
Check Company UK is an independent service that uses public Companies House data to make company information easier to search and review. We are not Companies House and we are not operated by the UK Government.
Companies House makes public company information available through its register and API, including basic company information, registered office details, company status and other public filing data.
Companies House states that it does not check the accuracy of information filed on the register. Registration data should therefore be used as one part of a broader company check.Common questions
UK Company Registration Check FAQs
How do I check company registration in the UK?
Search by registered company name or Companies House number. Open the matching record and confirm the company number, status, incorporation date and registered office details.
How can I tell if I have found the correct company?
Do not rely on the name alone. Compare the unique company number, registered office, incorporation date and current company status.
Does every UK business have a Companies House number?
No. A Companies House number applies to entities registered with Companies House. Some businesses, including many sole traders, are not incorporated companies and will not have a company registration number.
Does an active company status mean the business is safe to deal with?
No. An active registration status is not a guarantee of creditworthiness, reliability or trading conduct. Consider the wider company record and any other checks relevant to your decision.
Can I check registration using only a company number?
Yes. Using the company number is one of the most precise ways to locate a specific registered company because the number identifies the legal entity.
