Selecting a company name is one of the first and most important steps in setting up a business in Ireland — and understanding the rules around company name registration ensures CRO approval first time. Not every name will be accepted by the Companies Registration Office (CRO), and certain rules apply to ensure clarity, uniqueness, and compliance with the law.
This guide outlines the key considerations, restrictions, and procedures to help you avoid delays and ensure your company name passes CRO approval.
Don’t Commit Before Approval
The CRO strongly advises against spending money on branding, signage, or domain names until your chosen company name has been officially approved and the Certificate of Incorporation has been issued.
When Can a Name Be Refused?
The CRO may reject a proposed company name if it:
- Is identical or too similar to an existing company name on the register
- Contains offensive language
- Implies state sponsorship or misleading authority
Words Requiring Special Permission
Certain terms require prior approval from relevant authorities before being used in a company name:
- “Bank”, “Banking”, “Banc” – Only with permission from the Central Bank of Ireland
- “Society”, “Co-op”, “Co-operative” – Must be approved by the Registrar of Friendly Societies
- “University”, “Institute of Technology”, “Regional Technical College” – Require approval from the Department of Education
- “Architect” – Use restricted to those authorised by the Royal Institute of the Architects of Ireland (RIAI)
- Exemptions: Terms such as “landscape architect”, “architectural technologist”, or “interior design architect”
Additionally:
- The word “Standard” is prohibited
- “Credit Union” is restricted under the Credit Union Act 1997
- “Charity” or similar may trigger further documentation requirements from the CRO
General Naming Rules & CRO Guidelines
To avoid rejection or objection, keep the following in mind:
- Include Distinctive Words: Generic words such as “company”, “co”, “limited”, “services”, or punctuation (like “&”) do not make a name sufficiently unique.
- Place Names Aren’t Enough: Words like “Ireland”, “Dublin”, or regional locations are not adequate to differentiate names.
- Avoid Similar Descriptions: Terms like “group”, “international”, “systems”, or weak qualifiers won’t help distinguish your name from others.
- Made-Up Words: If you’re using a unique, non-dictionary word, ensure it’s not phonetically or visually similar to existing names.
- Avoid Phonetic Similarity: Names that sound the same or are minor spelling variations of existing ones will be refused.
- Numbers & Years: Using a number or a year (e.g., “2024”) does not make a name sufficiently different unless the companies are part of the same group.
Objections After Incorporation
Under Section 30 of the Companies Act 2014, even if a name is approved, it may still be challenged within six months of incorporation if deemed too similar to an existing registered name.
In such cases, the Registrar of Companies can issue a direction to change the company name. If this happens:
- The company must comply within six weeks of the Registrar’s order
- Failure to comply may result in prosecution
