Key Changes in Companies House Rules for 2025

Under the Economic Crime and Corporate Transparency Act 2023, effective from March 2024, Companies House has new powers to challenge inappropriate company names. These changes strengthen protections against fraud and misrepresentation.

• Fraudulent Names Rejected: Names suspected of facilitating fraud can now be refused.
• No Misleading Associations: Names suggesting false connections to governments or international bodies are prohibited.
• Computer Code in Names Banned: You can no longer register names containing programming code.
• Sensitive and Offensive Names Scrutinised: Names deemed potentially offensive or harmful will face stricter evaluation.

These reforms help safeguard the integrity of the business landscape, making it more difficult for bad actors to exploit the system. You can read more about these changes on the Companies House Blog.

How to Choose a Compliant Business Name

To avoid rejection, follow these guidelines when picking a company name:

• Check for Existing Names: Use the Companies House register to ensure your desired name isn’t already taken.
• Avoid Restricted Terms: Words like “government” or “bank” require special approval.
• Steer Clear of Offensive Language: Even subtle or evolving slang could lead to rejection.
• Think Long-Term: Choose a name that aligns with your brand vision and is unlikely to become controversial.

It’s a good idea to brainstorm several name options and test them with your team or potential customers. A little extra effort upfront can save you significant headaches down the line.

Practical Tips for Naming Your Company

• Use a Business Name Generator: Tools like Namechk or Namelix can spark creative ideas.
• Get Feedback: Share your name ideas with trusted partners or clients.
• Secure Your Domain: Ensure the corresponding web domain is available to maintain brand consistency.
• Check Trademark Availability: Search the UK Intellectual Property Office database to avoid legal issues.
• Think About SEO: Choose a name that aligns with relevant keywords to improve your online discoverability.

Common Naming Mistakes to Avoid

• Overly Complicated Names: Names that are too long or difficult to spell can confuse customers.
• Ignoring Global Considerations: If you plan to expand internationally, check for unintended meanings in other languages.
• Neglecting Social Media Handles: Make sure your business name is available on key social platforms.
• Skipping Legal Checks: Even if a name seems available, failing to check trademarks could lead to legal battles.

By steering clear of these pitfalls, you’ll increase the chances of your name being accepted and build a stronger brand foundation.
