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

Ensure your name meets Companies House rules in seconds using our free company name check tool.

It must be unique

Your name can’t be identical or similar to an existing business; consumers must easily tell you apart.

It needs to end in “Limited” or “Ltd”

This suffix is mandatory for limited companies (or "Cyfyngedig" / "Cyf" in Wales).

It can’t include sensitive words

Skip restricted words to prevent registration delays, as these require government review.

It can’t be offensive

Ensure your name carries no offensive connotations, keeping international cultural differences in mind.

Company Name Check FAQs

Our search tool will check if your company name is available against over 4 million registered companies in the Companies House database.

No. Companies House rules state that every company must have its own unique name. Our business name checker will make sure your chosen name is available before you try to register your limited company.

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.

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.

A business or trading name is a name you trade with, but is not the same as your registered company name. Our guide on company names vs trading names explains the difference and when you may wish to use a trading name.

You can register a limited company and leave it dormant until you’re ready to start trading, to stop anybody else registering your chosen name with Companies House. Additionally, you may wish to register your company name as a trade mark, which will legally prohibit others from using it.

It’s not possible to reserve a company name without forming a limited company under that name. 

All private limited companies must include “Limited” or “Ltd” unless they are exempt through certain criteria. For example, your private company must be limited by guarantee.

When a company is dissolved, it is removed from the Companies House register. This means it no longer exists legally and you can reuse the name.
