Changing a company name: update the business bank account without confusing payers

Changing a limited company's name does not create a new company. The legal entity continues, but banks, customers and payment systems still need the new name reflected accurately. The safest transition updates the legal record first, then the bank, invoices and payment platforms in a controlled sequence.

The new company name takes effect when Companies House issues the new certificate

Companies House says the company name changes when it is registered and a new certificate is issued showing the name and registration date. The Companies Act 2006 says the change takes effect from the date on the new certificate of incorporation. Before that point, the proposed new name is not yet the company's legal name.

Use the new certificate as the start of the banking update. Do not send invoices in the new legal name while the bank and official register still show only the old one unless advisers have confirmed the correct transitional wording. A short, controlled changeover reduces customer confusion and payment-name mismatches.

Notify the bank separately because the legal filing does not automatically rewrite banking records

The company remains the same legal entity, but the bank maintains its own customer records and KYC information. Contact the provider after the name change is effective and ask what evidence it requires. The new certificate of incorporation and updated Companies House record are the natural starting documents.

Review every facility held in the company name: current account, savings, foreign-currency accounts, cards, loans, merchant acquiring and payment-provider accounts. A business can successfully update the main current account while leaving a credit card or online-payment profile under the old name, creating inconsistent customer and compliance records.

Do not assume the sort code, account number or service terms will change

The Companies Act says a name change does not affect the company's existing rights or obligations. The company is not a newly incorporated legal person simply because the name changed. However, the bank controls its own account-title process and operational changes, so the business should ask the provider exactly what will remain the same.

Do not print new invoices stating that bank details are unchanged until the bank confirms the updated account title. Equally, do not open a new current account automatically unless there is a separate business reason. The goal is continuity of the existing legal entity with accurate banking records.

Tell customers which payee name to use so Confirmation of Payee checks make sense

Pay.UK says business payees should be entered using the registered business name or a trading name registered to the account. During a company-name transition, customers can therefore see close-match or no-match warnings if the bank has updated its records but the invoice still shows the former name, or vice versa.

Once the bank confirms the new account title, update invoice templates and tell regular customers the legal name has changed while the company remains the same entity. For a transition period, include wording such as "formerly Old Name Ltd" where commercially appropriate. That helps customers recognise the relationship without asking them to ignore a payment warning.

Update merchant acquirers, payment platforms, cards and recurring suppliers

A merchant acquirer or payment provider may display the legal merchant name on customer statements, contracts or settlement records. Notify those providers and check whether they require fresh company documents or beneficial-owner verification. The same applies to expense platforms and finance software connected to the bank.

Review physical and virtual cards, direct debit instructions and supplier portals. Some services update automatically when the underlying bank profile changes; others do not. Create one change log showing each provider, date notified and date confirmed so the finance team can see which systems still use the old name.

Preserve the old name in historic records so earlier transactions remain traceable

The Companies Act says a change of name does not affect existing rights, obligations or legal proceedings. Historic contracts, invoices and bank statements under the former name remain part of the same company's record. Do not rewrite old accounting documents simply to make every year look as though the new name always existed.

Keep the new certificate of incorporation with the company records and update the accounting system from the effective date. If a lender, auditor or customer sees an older statement in the former name, the certificate explains the continuity. The objective is a clean legal trail from old name to new name, not an artificial erasure of the company's history.
