Source-based general information, not professional advice. How we research and review

A company name change normally needs a special resolution or authority provided by its articles, followed by registration at Companies House. The legal change takes effect when registered, not when the board chooses the new brand. The company number and legal identity remain the same.
Decide whether the legal name needs to change
A trading name can be different from the company’s registered name. Rebranding a product or website does not always require a legal name change, provided the correct legal disclosures remain clear. If the registered name is misleading, unsuitable for expansion or tied to a departed founder, a formal change may be appropriate. Write down whether the project concerns the legal entity, a product brand or both.
Changing a name does not create a new company, cancel liabilities or reset filing dates. Contracts still involve the same entity. Keep the company number as the stable identifier during the transition, particularly when customers and suppliers update their systems. A change of ownership is also a separate event, not something achieved by renaming.
| Action | What changes | What stays the same |
|---|---|---|
| Adopt a trading name | Customer-facing brand | Registered legal name and identity |
| Register a company name change | Legal name on the register | Company number and existing obligations |
| Create a new company | A new legal entity | Old company’s liabilities remain with it |
| Transfer shares | Owners of the company | Company’s identity and contracts, subject to terms |
Check naming rules and brand risk
Search Companies House for the proposed name and assess “same as” restrictions, sensitive words and permission requirements. Acceptance by Companies House does not prove that a name is safe from trade mark or passing-off disputes. Search the Intellectual Property Office register and consider professional clearance if the brand is commercially important.
Check domains, social handles and customer confusion, but do not treat a free domain as legal permission. Obtain any required approval for sensitive words before filing. If the new name suggests a regulated profession or public-body connection, take particular care. Keep a shortlist in case the preferred name cannot be registered or conflicts with existing rights.
- Search existing registered company names and relevant trade marks.
- Check sensitive or restricted words and any approval evidence.
- Assess whether the brand implies a regulated status you do not have.
- Reserve domains only after a proportionate risk check.
- Do not announce a legal name change before it is registered.
Use the correct approval route
The usual route is a special resolution of shareholders. A special resolution normally requires at least 75% support under the applicable voting procedure. The articles may provide a different permitted mechanism for changing the name. Directors should not assume their ordinary management powers alone authorise the change; check the constitution and any shareholder agreement.
Document the decision, date, proposed name and voting result. For a written resolution, follow the statutory rules and retain evidence of agreement. If the company has several share classes or investor consent rights, check those as well. A unanimous informal conversation is poor evidence if a later dispute arises.
- 1
Review the articles and any investor consent provisions.
- 2
Check the proposed name and obtain required permissions.
- 3
Pass the appropriate resolution or follow the articles-based mechanism.
- 4
Keep the approved documents and complete the required filing.
- 5
Wait for confirmation that Companies House has registered the change.
- 6
Update trading disclosures and notify counterparties using the company number.
File and confirm the effective date
Use the current official service or an authorised filing agent and select the route that matches the approval. Companies House provides separate forms for a change by resolution and a change under the articles. Current filing fees and expedited options should be checked on the official service; a formation provider’s rebrand service may add its own fee.
After acceptance, obtain the change-of-name certificate and check the public register. Rejection can occur if the name or documents are unsuitable, so allow contingency time before printing stationery or launching a campaign. Continue using the existing legal name until registration makes the change effective. Retain the certificate with the original incorporation documents.
| Record | What to verify | Why keep it |
|---|---|---|
| Resolution or approval | Correct name and procedure | Evidence the change was authorised |
| Companies House submission | Approval route and supporting documents | Explains what was filed |
| Acceptance and certificate | Registered name and effective date | Evidence for banks and counterparties |
| Public register | Name matches the intended spelling | Catches filing mistakes promptly |
Coordinate the practical changeover
Update the company’s legal details on invoices, purchase orders, websites, email footers, signage and business letters as applicable. Notify the bank, financial providers, insurers, landlord, major customers and suppliers. Check HMRC services and registrations separately rather than assuming every tax record immediately follows the Companies House update.
Contracts do not normally need replacement merely because the same company changes its name, but notice obligations or system changes may apply. A short notice identifying the old name, new name, effective date and unchanged company number is usually clearer than a vague rebrand announcement. Bank-detail changes deserve separate fraud controls: customers should verify any new account through a trusted contact channel.
Worth knowing: A name-change notice should make continuity clear. It is not an opportunity to obscure debts, ownership or who supplies the customer.
Worked scenario: a consultancy expands its services
Illustrative scenario: Greenbridge Design Limited adds engineering services and wants to become Greenbridge Projects Limited. Its shareholders approve a special resolution after checking naming and brand risks. The team files the change and waits for the certificate rather than issuing invoices in the proposed name on the vote date.
After registration, the finance lead updates invoice templates, the bank and relevant tax accounts. Existing customers receive a notice quoting the same company number and explaining that contracts remain with the same entity. The website retains the old trading brand for one product but displays the new legal name. The company’s accounts deadline does not move.
| Before approval | Between approval and registration | After registration |
|---|---|---|
| Check availability and rights | Use the existing legal name | Use the new legal name |
| Review constitution and consents | Prepare customer-system changes | Notify banks and counterparties |
| Budget filing and rebrand costs | Wait for certificate before legal switch | Retain certificate and confirmation records |
Coordinate the legal name change with the rebrand
A company rebranding from a founder’s name to a broader trading brand should first search the proposed legal name and review restricted or sensitive words. Availability at Companies House does not establish trade mark clearance or domain ownership. It checks the articles for the permitted decision route and confirms any member resolution requirements. The directors retain the actual approval and submit the correct change filing. They use the official fee schedule at the time of filing rather than a quoted historic charge. A logo redesign does not change the registered legal name.
The company continues to use its current legal name until the change has been properly registered and evidenced. The company number remains the key identifier for the same legal entity, so existing liabilities and contracts are not erased. The company reviews agreements for notification obligations and informs banks, insurers, payment providers, accountants and major customers through their official change processes. It preserves the name-change certificate alongside the original incorporation certificate. Where finance or licensing records need formal updates, it obtains confirmation rather than assuming a public-register update propagates everywhere.
The practical rebrand plan includes invoices, quotations, purchase orders, email signatures, websites, signage and employment documents. It distinguishes a legal-name change from continuing to use a trading name, and keeps the required company disclosures visible. Customer payment instructions are handled securely: an announcement about a new name should not look like a fraudulent request to send funds to an unfamiliar account. The company verifies any banking changes through trusted channels and explains that the legal entity is unchanged where that is the case. Old invoices remain identifiable and are not simply deleted.
The directors also plan redirects and record continuity. The old website and email may need to remain accessible during the transition, subject to a secure arrangement. Historical accounts and contracts can retain the name that applied when they were created, with the company number linking the record. Staff know which name to use on new documents and who answers customer questions. The compliance calendar remains in place; a name change does not restart the accounts or confirmation-statement timetable. A final review checks the register, provider records and public disclosures for consistency.
| Review point | Practical action | Evidence or decision |
|---|---|---|
| Approval | Follow articles and member process | Resolution and filing receipt |
| Registration | Wait for legal effectiveness | Change-of-name certificate |
| Operational updates | Notify relevant providers | Acknowledged record changes |
| Continuity | Preserve historical identity | Company number and old-document trail |
Avoid stale documents and confusing ownership changes
A frequent operational problem is a mixture of old and new names on quotes, accounts and customer portals. Appoint a change owner and keep an inventory of documents rather than assuming the website is the whole business. Old invoices remain evidence of transactions made under the previous name; do not erase or rewrite records merely to make everything look uniform.
If the rebrand coincides with a sale, asset transfer or new entity, separate those steps. Customers need to know whether their contracting party has genuinely changed. Professional advice is particularly useful where licences, regulated permissions, cross-border registrations or large long-term contracts are involved.

Common questions
Does my company number change?+
No. A registered name change does not change the company’s number or create a new entity.
Can directors change the name without shareholders?+
Only if a valid mechanism in the articles permits the relevant route. Otherwise use the appropriate shareholder resolution.
Do I need to rewrite every contract?+
Not normally just for a name change, but check notice clauses, licences and counterparty systems.
