How does our company name check work?

When you run a limited company name check, our search tool will cross reference your business name against the Companies House register. This includes every company in the UK - both active and dissolved.

We will also check your name to make sure it hasn’t already been used or contains any of the sensitive words not permitted by Companies House.

Sensitive words are terms and expressions that cannot be used in company names because they could potentially mislead the public.

Company Name Check FAQs

How do I check if a business name is available?

How will I know if my company name contains any sensitive words?

Our company name check won’t just tell you if your business name is available, it will also check it against the list of sensitive words to ensure it meets Companies House rules too.

How do I know if my business name is unique?

Our company name search tool will check your business name against over 4 million registered companies in the Companies House database. It will confirm whether your name is unique and available to be registered.
