Changing your company name

A company can change its registered name without becoming a new legal entity. The process requires the appropriate authority and Companies House registration. A new logo, website or trading name is not itself a registered company name change. ^[1]

Check the proposed name before committing

Search the company register and consider the naming rules, including similarity, sensitive wording and required permissions. Companies House acceptance does not settle every trade mark or branding issue. Review the proposed name before paying for extensive materials or announcing a firm launch date. ^[2]

Keep a fallback option where availability or permission is uncertain. A customer-facing rebrand can be expensive to reverse if the legal name cannot be registered as expected.

Identify the approval route

A company may change its name by special resolution or through permission contained in its articles. Review the actual constitution and obtain the required decision. The filing route depends on how the change was authorised. ^[1]

Record the precise new name, including the ending required for the company type. Small differences between the resolution and application can delay the process or create uncertainty about what was approved.

Register the change and retain the evidence

Use the current Companies House process and check the applicable fee. The company name does not officially change until Companies House registers it. Keep the resolution or other authority, submission evidence and resulting certificate together. ^[1]

Avoid presenting the change as completed while the application is still pending. If documents must be signed during the transition, use a clear and accurate description of the existing legal entity.

Coordinate the business handover

• Update invoices, website disclosures and business correspondence.
• Notify banks, insurers, lenders and relevant professional bodies.
• Check tax and licensing records for separate notification processes.
• Review notice requirements in material contracts.
• Inform customers through trusted communication channels.
• Retain the former name and company number in the historical file.

Keep identity clear for counterparties

The company number remains a useful link between old and new names. Explain the change to customers who reconcile invoices or purchase orders under the former name. Do not combine a name change with an unexplained request for new bank details.

For example, a consultancy rebranding before an investment round should ensure that the investment papers, bank records and updated articles all identify the same company. The change is easier to follow when the completion record shows the old name, new name, registration date and unchanged company number.

Plan the legal change and the brand launch separately

A registered name change can sit within a wider rebrand, but the two timetables should not be confused. Decide when the legal name must change, when customers will see the new brand and when old materials will be withdrawn. Allow for registration queries without promising that a marketing launch proves the company name has already changed.

Keep a name-change record showing the old name, exact new name, company number, approval and registration evidence. This helps suppliers connect historic purchase orders with later invoices. It also makes due diligence easier: a counterparty can follow the same legal entity through the change rather than incorrectly treating it as a replacement business.

Test the proposed name against practical uses

Check the spelling in email addresses, payment references, domain names and accounting systems. A long legal name may need a separate trading style, but disclosures should still identify the correct entity. Ask whether existing licences or professional registrations impose their own name requirements. Companies House acceptance is only one part of this review.

A company that changes its name to match a product brand should also check the brand's ownership and permissions. If the founder personally owns the trade mark, renaming the company does not transfer that right. Resolve the ownership or licence question through the appropriate documents before presenting the brand as an unrestricted company asset.

Control customer communications

Send the announcement through established channels and keep payment instructions clear. If bank details are unchanged, say so in the customer notice. If a separate bank change is genuinely necessary, use the customer's agreed verification process. Combining several unexplained changes in one urgent email can make a legitimate rebrand difficult for customers to distinguish from payment fraud.

Update recurring invoice templates and automated messages, not only the homepage. Check procurement portals, insurance schedules and major contract notices. Keep a transition list with the person responsible for each change so that the finance team does not continue issuing new invoices under the former legal name indefinitely.

Preserve the transaction history

Existing contracts should be reviewed for notification requirements, but a name change does not itself create a new contracting entity. Avoid signing replacement agreements merely to change the heading without considering whether their terms also change. Where an amendment or notice is needed, identify the company by its stable number and explain the registered change accurately.

For the trade mark distinction, read Trade marks and company names compared. Companies House filing review is relevant to the company filing work; describe whether the name change is standalone or part of a wider investment or rebrand requiring additional coordination.

If the project also involves moving contracts to another company, treat that as a separate transaction requiring its own analysis.
