What Happens to Salary Payments When You Switch Banks?

A full Current Account Switch Service move is designed to transfer regular incoming payments such as salary and to redirect payments that still arrive using the old account details. The practical task is to coordinate the switch with payroll cut-offs so payday remains predictable.

Salary is included in the full CASS switching process

CASS says all regular incoming payments, including salary and benefits, are transferred as part of a full switch. The process takes seven working days from the agreed timetable, the old current account closes on the switch date and the new account becomes the destination for regular payments.

Payments sent to the old account details are automatically redirected to the new account. CASS also says an automatic message is sent back to the originator advising them of the new account details so their records can be updated.

This redirection is a safety net, not a reason to leave payroll unchanged forever. Once the new account is open and the switch date is confirmed, provide the employer with the new sort code and account number through the employer's normal secure payroll process.

Ask payroll whether bank-detail changes require an employee portal, signed form or HR approval. The switch service can redirect an old-account payment, but it cannot bypass an employer's own security process for changing salary instructions.

Employer payroll cut-offs can mean one more salary uses the old details

Payroll files are often prepared days before payday. If the employer's payroll cut-off has already passed when you provide the new bank details, the next salary can still be sent using the old account information and then be redirected through CASS.

Ask payroll when changes need to be submitted for the next pay run. If the answer is the 15th of the month and you switch on the 20th, the next salary may legitimately be generated with the old details even though the switch itself is complete.

Keep the first payslip after switching and confirm the payment date and amount in the new account. This helps distinguish an employer payroll issue from a CASS redirection issue if wages appear late.

If payday falls on a weekend or bank holiday, confirm the employer's normal payment convention before blaming the switch for a date change. Payroll timing and CASS timing should be diagnosed separately.

Choose the switch date around payday and essential bills

A practical strategy is often to switch shortly after salary has arrived rather than immediately before payday. That gives time to verify the new debit card, app and account access before the next wage payment becomes essential.

Also look at the bills due just after payday. If rent, mortgage or several Direct Debits depend on the salary arriving first, keep a small buffer in the new account during the first month. The switch process should work, but a cash cushion reduces the consequences of any payroll timing problem.

A full switch date must be a working day and enough time must be allowed for the seven-working-day CASS process. Put the salary date, payroll cut-off and largest bill dates on one calendar before selecting the switch date.

Keep enough money for at least the most important bills if the first post-switch payday is close. The buffer reduces practical risk while payroll and the new bank complete their first full cycle together.

Redirection protects payments sent to the closed old account

CASS says payments sent to the old account are automatically redirected to the new account, and the sender is notified of the new details. This protection is particularly useful for salary, pension or benefits where the payer's records can take time to update.

Do not assume every incoming payment is salary. Freelance clients, family transfers and one-off refunds can also use the old details. CASS redirection can help with payments sent after closure, but updating important senders directly remains the cleaner long-term approach.

If you do not want the new bank to provide updated details to a payment originator, CASS says you should tell the new bank. Most customers, however, benefit from the sender being notified so future payments go directly to the new account.

Redirection also helps with bonuses, expenses or other employer payments sent using stored old details. Still, provide the new information directly so future credits reach the new account without relying on the redirection service.

Escalate a switch-caused salary problem to the new bank

The Current Account Switch Guarantee places responsibility for the switch with the destination bank. If a salary payment is disrupted because of the switching process, contact the new bank or building society and provide the switch date, expected salary date and employer evidence.

The guarantee says charges or interest incurred because something went wrong with the switch will be refunded. That protection is separate from a payroll error where the employer did not send the payment on time at all.

After the first successful salary reaches the new account directly, verify that payroll has updated the sort code and account number. The goal is for CASS redirection to remain a temporary safety mechanism, not the permanent route for monthly wages.

If the employer confirms it sent the payment correctly but the new account does not receive or redirect it, give the destination bank the payment date, amount and employer reference. Specific evidence speeds up investigation.

Sources and related guides

Salary-switching mechanics were checked on 30 September 2026 against the Current Account Switch Service. Future updates should verify the seven-working-day process, incoming-payment redirection and guarantee wording. Employer payroll cut-offs are separate from CASS, so the article should continue to distinguish a payroll file created with old details from a failure of the switching service itself.

Future reviews should verify incoming-payment redirection and guarantee wording from CASS. Employer payroll deadlines vary by organisation and should remain examples of operational timing rather than universal banking rules.
