Frequently Asked Questions

Is Companies House search free?

Yes. Basic company information on the UK register is public and free to look up, and this tool lets you search over 5.7 million UK companies at no cost. You can view a company's status, registered address, directors, SIC codes and filing history without paying.

What information can I find about a UK company?

You can see a company's registration number, incorporation date, status (active, dormant or dissolved), registered office address, SIC codes, directors and officers, and its filing history. This is drawn from the public Companies House register.

Can I search by company number as well as name?

Yes. You can search by company name or by the 8-character company registration number. Searching by number is the most precise way to find a specific company when several businesses share a similar name.

Can I look up a dissolved company?

Yes. Dissolved and dormant companies remain on the public register and can be searched. Their records show the historical details filed while the company was active, which is useful for due diligence and research.

How up to date is the company data?

Company records reflect what has been filed at Companies House. Most changes appear shortly after they are registered, but there can be a short delay between a company filing an update and it showing on the public register.
