Changing the legal name on a business bank account in the UK
A practical sequence for updating a UK business bank account after a company, partnership or trading entity changes its legal name.
Update the legal record first, then ask the bank to change the account name using its business-customer process. For a limited company, make sure Companies House shows the new name before sending evidence to the bank. Keep old and new account-name details during the transition because customers and suppliers may still use the previous name. Do not assume a bank-name update automatically changes payment references, cards, cheque books or connected accounting services.
For a limited company, complete the legal name change before the banking change
A UK limited company does not become a different legal entity simply because its registered name changes, but the bank needs evidence that the official name has changed. Companies House provides the filing route for a company name change and updates the public register once the change is effective. Use the new registered name consistently when you approach the bank, rather than asking the bank to adopt a name that has not yet appeared on the company record.
Keep the Companies House confirmation or certificate of incorporation on change of name with your banking records. The bank may also ask whether directors, beneficial owners, trading activity or registered office details have changed at the same time. If several details are changing, give the bank one clear schedule rather than piecemeal updates.
A trading name and a legal name are different
A business can market itself under a trading name while its bank account remains in the legal entity’s name. Changing branding, a website or a shop sign therefore does not necessarily require the same process as changing the legal name of the company or partnership. Tell the bank exactly which has changed. This matters for payment-name checks and for documents customers use to identify the business.
If only the trading address has changed, use our separate guide to changing the trading address on a business bank account. Mixing name, address and ownership changes into one vague request is a common cause of avoidable delay.
Expect the bank to refresh customer-due-diligence information
Banks must maintain accurate information about business customers, their purpose and, where relevant, beneficial owners. A legal name change can therefore trigger more than a cosmetic edit. The bank may ask for updated company information, identification for authorised people, details of ownership or confirmation that the nature of the business has not changed.
Answer consistently with Companies House and your tax or partnership records. If the name change accompanies a merger, ownership change or new line of business, say so rather than treating it as a simple rebrand. The bank is trying to understand whether its existing customer record still describes the business accurately.
Plan for payment-name checks and incoming payments during the transition
Customers may continue to send money using the old name for some time. Confirmation of Payee compares the account name with the name entered by the payer, so ask the bank how and when its systems will recognise the new name and whether the old name will continue to be accepted as an alias. Do not promise customers that a name check will behave in a particular way until the bank has confirmed its setup.
Update invoices, supplier portals, payroll instructions and saved beneficiary details in an organised sequence. If the business receives many bank transfers, tell key customers before the change and provide the unchanged sort code and account number only through a trusted channel. A name change is also a moment when invoice-redirection fraud can exploit confusion.
Check every banking item that carries the old name
After the main account name changes, review cards, cheque books, deposit slips, statements, finance agreements and connected accounting feeds. Some items update automatically; others need replacement. If the business has several accounts, verify each one rather than assuming one request changed the whole relationship.
Also review who is authorised to operate the account. A legal name change sometimes happens alongside changes in directors or partners. Our guide to adding or removing business account signatories explains why the mandate should be treated as a separate control.
Keep evidence that links the old and new names
Retain the Companies House confirmation, bank correspondence and the first statement showing the new name. This can help when an accountant, supplier or customer needs to connect historic transactions with the renamed business. Do not destroy old statements just because the new name is live; the company’s accounting and tax records still need continuity.
If the bank has not updated the name after the period it quoted, ask which verification step is outstanding and request a written case reference. Where a mismatch is disrupting incoming payments, explain that operational impact clearly so the issue can be prioritised appropriately.
Frequently asked questions
Will the sort code and account number change when the company name changes?
Often they do not, because the legal entity and account can remain the same, but only the bank can confirm this for your account. Never assume that payment details are unchanged without checking.
Can I ask the bank to use a trading name instead of the legal company name?
Provider rules vary. Some banks can display or record trading names, but they still need the legal customer identity. Ask how the name will appear on statements and Confirmation of Payee.
Should I change the bank before or after Companies House?
For a limited company, complete the legal name change first so you can give the bank official evidence of the new registered name.

I would treat a business name change as a controlled migration rather than a single bank form. The legal record comes first, because the bank needs an authoritative basis for changing the customer name. Then I would map every place where the old name appears: bank accounts, cards, invoices, supplier systems, accounting software and customer payment instructions. The operational risk is not usually that the bank account disappears; it is that different systems change at different times and customers are unsure which name to use. That uncertainty can also create an opening for fraud, so payment details should be communicated through trusted channels and not simply copied from an unexpected email. I would keep the old and new names linked in the business records for a reasonable transition period and retain the Companies House and bank confirmations permanently with the corporate file. If the name change also involves new directors, owners, address or business activity, I would tell the bank in one coherent update instead of presenting each item as unrelated. A clean evidence trail makes the bank’s due-diligence work easier and gives the business a clear record if a customer, auditor or supplier later questions why historic payments use a different name.
