Can You Actually Change Your Company Name?
Yes, Irish companies can change their registered names at any time after incorporation through a straightforward legal process.
Section 27 of the Companies Act 2014 provides the statutory framework for name changes and sets out the requirements.
The company remains the same legal entity with the same registration number - only the name changes on public records.
This flexibility allows businesses to rebrand, correct mistakes, or adapt their names as business direction evolves.
Why Do Companies Change Names?
Several business situations make name changes sensible or necessary:
Rebranding initiatives: Modernizing outdated names or reflecting strategic shifts in business focus.
Market expansion: Removing geographic limitations like "Dublin Web Design Ltd" when expanding nationally.
Merger situations: Combining names after acquisitions or creating unified brands for group structures.
Correcting mistakes: Fixing spelling errors or awkward wording from hasty incorporation decisions.
Avoiding confusion: Distinguishing from competitors with similar names causing market confusion.
Trademark alignment: Matching company names to registered trademarks after securing intellectual property rights.
The process costs just €30 and takes a few weeks, making it accessible for most situations.
What Are the Naming Restrictions?
The new name must comply with CRO naming rules that prevent confusion and protect the public.
Key restrictions include:
Availability: The name cannot be identical or too similar to existing company names on the CRO register.
Prohibited words: Certain words require authorization, including "bank," "insurance," "university," "chartered," and government-related terms.
Misleading names: Names suggesting activities the company doesn't undertake or implying government connection are prohibited.
Offensive names: The CRO refuses names considered offensive or contrary to public policy.
Proper endings: The name must end with "Limited," "Teoranta," "Ltd," or appropriate abbreviations for your company type.
The CRO's online search tool lets you check availability before starting the change process.
Step 1 - Check Name Availability
Before initiating a name change, verify the desired name is available through the CRO's public search. The checking process involves:
- Visit cro.ie and select "Search Company"
- Enter your proposed new name exactly as intended
- Review results for identical or very similar names
- Consider variations if your first choice is too similar
- Check trademark databases at ipoi.gov.ie to avoid IP conflicts
Names are assessed on the "too similar" test, which is somewhat subjective and considers phonetic similarity and overall impression.
If in doubt, contact the CRO directly at info@cro.ie to query whether a proposed name would be acceptable.
Step 2 - Special Resolution Process
Name changes require a special resolution passed by at least 75% of shareholder votes under Section 191. The resolution process involves:
For meetings:
- Give shareholders at least 14 days' notice of the meeting
- Clearly state the proposed new name in the notice
- Hold the meeting and vote on the resolution
- Record the vote in minutes showing 75%+ approval
For written resolutions:
- Circulate the resolution to all shareholders
- Include the exact new name and reason for change
- Collect signed approvals from 75%+ of voting shares
- Record which shareholders approved and when
Most small companies use written resolutions because they're faster and avoid meeting coordination hassles.
Step 3 – File the Necessary Documents
After passing the special resolution, file Form B10 with the CRO along with supporting documentation. Required documents include:
Form B10: The standard form for notifying changes to company details, indicating this is a name change.
Special resolution: Copy of the meeting minutes or signed written resolution showing 75% approval.
Amended constitution: If your constitution states the company name, file the amended version reflecting the new name.
Filing fee: €30 payment processed through the CORE system.
All documents must be filed within 28 days of passing the resolution to comply with statutory deadlines.
How Do You Complete Form B10?
Form B10 is filed electronically through the CRO's CORE system at core.cro.ie. The filing steps are:
- Log into CORE using your company credentials
- Select "File a Form" and choose Form B10
- Indicate name change as the reason for filing
- Enter old name currently on the register
- Enter new name exactly as it should appear
- Upload resolution showing shareholder approval
- Pay €30 fee electronically
- Submit and save confirmation
The system validates the new name against existing names and flags potential issues before accepting the filing.
How Long Does the Process Take?
The complete name change process typically takes 2-3 weeks from resolution to new certificate.
Timeline breakdown:
Week 1: Prepare and pass special resolution (faster with written resolutions than meetings).
Week 2: File Form B10 and await CRO processing (standard processing is 5-10 working days).
Week 3: Receive new certificate of incorporation showing the updated name.
Urgent processing isn't available for name changes - the standard timeline applies to all applications. Plan accordingly if the name change must complete by a specific date for commercial reasons.
What Certificate Do You Receive?
The CRO issues a new certificate of incorporation showing the company's new name once the change is approved.
This certificate states:
- The company's new name
- The company registration number (unchanged)
- The date the name change took effect
- Confirmation it's issued under Section 27
The original certificate remains valid for historical purposes, but the new certificate supersedes it for current identification. Keep both certificates in your company records - the original proves incorporation date while the new one shows current name.
When Does the Change Take Effect?
The name change takes legal effect from the date shown on the new certificate of incorporation issued by the CRO. Until that date, the company must continue using its old name on all official documents and correspondence.
Contracts signed, invoices issued, or obligations incurred before the change date remain valid under the old name. After the change date, the company must use its new name on all new documents, though existing contracts don't need amending.
What About Bank Accounts?
Bank accounts must be updated to reflect the new company name through the bank's standard procedures. The update process typically involves:
- Written notification to the bank about the name change
- Certificate copy providing the new certificate of incorporation
- Form completion using the bank's account amendment forms
- New cards/cheques issued with the updated name
- Processing time usually 1-2 weeks
The account number remains unchanged - only the account name updates to match the new company name. Coordinate timing carefully to avoid payment issues during the transition period.
Should You Keep Trading Names?
Many companies maintain trading names (business names) different from their legal registered name. The relationship works as follows:
- Registered name: The legal name filed with the CRO, used on official documents
- Trading name: The brand name used in marketing and customer-facing materials
Trading names must be registered separately with the CRO under Section 32 if different from the registered name. This flexibility lets companies maintain brand continuity while updating legal structures.
What About Company Numbers?
The company registration number never changes regardless of name changes, ensuring continuity in official records. The registration number:
- Appears on the certificate of incorporation
- Must be shown on business letters and order forms
- Provides unique identification in CRO databases
- Links all historical filings and records
This permanent identifier means anyone researching the company can trace its complete history despite name changes.
Can Creditors Object to Name Changes?
Creditors cannot formally object to name changes, but Section 27 protects them by ensuring obligations continue under the new name. The company remains fully liable for all debts and obligations incurred under the old name.
Legal proceedings commenced against the old name continue validly despite the change. Companies cannot use name changes to avoid debts or confuse creditors about their identity.
