UK business name checker – See if your company name is available
Choosing the right company name is one of the first and most important steps when setting up your UK limited company. But before you get too attached to an idea, you’ll need to check if your preferred name is available and meets the rules set by Companies House.
Use our free UK company name checker tool below to instantly find out if your desired name is available — and avoid delays during registration.
How it works
Our business name checker connects directly to the Companies House database to search all existing company names registered in the UK.
Just type your preferred name into the box below and click “Check Availability.” You’ll get an instant result showing whether it’s available to register or if you need to try a different variation.
What makes a name acceptable?
Companies House has strict rules about what names can be registered. To be accepted, your company name must:
- Be unique – It must not be identical or too similar to an existing company.
- End in “Limited” or “Ltd” if forming a private limited company.
- Not contain sensitive or restricted words or expressions without approval (e.g., “Bank”, “British”, “Authority”).
- Avoid names that could mislead the public or imply a connection with the government.
Need help navigating these rules? Our team at Mint Formations is happy to guide you.
