How does our company name checker work?

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

We ensure your company name hasn’t been used in the past, and compare it against sensitive words that Companies House doesn’t allow.

What to consider when choosing a business name

To get registered quickly, your company name needs to follow Companies House rules. Our free company name check tool will let you know if your name complies in a matter of seconds.

It must be unique

Your company name can’t be the same as another company’s, nor can it be similar. Consumers must be able to tell you apart from other businesses. 

It needs to end in “Limited” or “Ltd”

Whether you use “limited” or “ltd” is entirely up to you, but it is mandatory for all limited companies. In Wales, “Cyfyngedig” or “Cyf” is accepted.

It can’t include sensitive words

To avoid delays in company registration, omitting sensitive words from your business name is wise. While in some cases it’s possible to include them, they will need to be government-reviewed. 

It can’t be offensive

Be wary of offensive connotations when choosing your company name, especially if you plan to trade internationally. Although this may seem like common sense, other cultures may perceive certain terms as offensive, that you do not.
