What does Companies House do?

Companies House is responsible for incorporating and dissolving limited companies, maintaining the official register of companies, and making company information available to the public.

It collects information from companies as required by law (around 5 million UK companies), including details about directors, shareholders, accounts, and company activities.

Publicly accesible data includes:

Company status (active, dissolved, liquidation)
Registered office address
Directors and officers
Filing history and documents
Financial accounts
Persons with Significant Control (PSC)
Charges and mortgages
Insolvency information

The lowdown: Companies House is a quick and reliable way to identify registered UK companies, their directors, and key filings but because the information is largely self-reported by companies, results should be verified with additional sources before being treated as fully accurate/complete.

How to Use:

Go to the Companies House search page and enter a company name or company number.

Select the relevant company from the results list to view its company overview page.

Review company information including filing history, people, accounts, registered address, and incorporation details. Note: documents can often be downloaded as PDF filings.

It’s frequently used alongside OSINT tools such as corporate registries, financial databases, and sanctions lists.
