What this site is

Company Name Checker is a free information service. It is independent and not affiliated with Companies House or any part of the UK government.

Name check results are a guide

The name checker applies the published Companies House "same as" rules to Companies House data. Our data is updated monthly and checked against Companies House live where possible, but it can be out of date, and Companies House can also object to names that are "too like" another or that use sensitive words. Only Companies House can accept a name, and it does so when you file. Don't buy branding, domains or stationery based only on our result.

Not professional advice

Our guides explain official rules in plain English. They are not legal, tax or financial advice. Check the linked official sources, or speak to a professional, before making decisions.

Fair use

Please don't use automated tools to send large numbers of name checks. We may limit or block traffic that affects the service for others.

Links to other sites

We link to other sites, including registration and business account providers. We're not responsible for their content or services. See how we're funded for whether any link earns us money.
