What happens to Direct Debits when you switch current accounts?
Under a full Current Account Switch Service switch, existing Direct Debits and standing orders are moved to the new current account and the old account closes on the agreed date.
With a full CASS switch, your regular outgoing payments—including existing Direct Debits and standing orders—are transferred to the new account. The process takes seven working days. Avoid setting up new payment arrangements on the old account during that final seven-working-day window because they may not be included.
CASS moves existing regular payments
The Current Account Switch Service is designed to move an eligible current account as one package. The new bank arranges the transfer of regular incoming payments and outgoing payments, including Direct Debits and standing orders, along with the old account balance. The old current account is closed on the agreed switch date.
This is different from manually opening a second account and changing bill details yourself. A full CASS switch includes the Current Account Switch Guarantee and automatic redirection of payments accidentally sent to the old account.
The seven-working-day window matters
Once the new account is open, you agree a switch date at least seven working days away. CASS warns customers not to set up new Direct Debits or standing orders on the old account during the seven working days leading up to the switch because those new arrangements may not transfer. Put any new mandate on the new account instead.
You can generally continue using the old current account until the switch date, but keep enough money available for payments due before that date. Do not manually cancel every existing Direct Debit simply because a CASS switch is scheduled; doing so can interfere with the automatic transfer process.
What the company collecting the Direct Debit sees
The switching process updates payment instructions behind the scenes. Some organisations may later show the new bank details in your customer account, while others may keep a mandate reference that looks unchanged. Your job is mainly to check that the first collection after the switch is taken from the correct new account and for the expected amount.
If a collection date falls very close to the switch date, watch both accounts and keep the bill provider’s confirmation. CASS is designed to prevent missed payments, but a clear record makes any correction easier if a problem occurs.
What if a Direct Debit goes wrong because of the switch?
The Current Account Switch Guarantee says that if something goes wrong with the switch, interest or charges incurred on the old or new account as a result will be refunded. Contact the new bank, which is responsible for managing the switch, and provide the payment date, organisation and amount.
This switching protection sits alongside the separate Direct Debit Guarantee that applies to qualifying Direct Debit payment errors. If you are unsure which process applies, explain exactly what happened rather than asking generally for a refund.
Check salary and other incoming payments too
CASS also redirects incoming payments such as salary. That reduces the risk of money being lost if a sender still uses the old details. Even so, update important senders directly once the new account is running. For employment income, see how to change the bank account used for salary.
If you are overdrawn, agree the new borrowing arrangement before the switch. Switching while overdrawn explains why the payment switch and the credit decision are separate.
A simple post-switch check
After the first month, compare the new account with the last old-account statement. Confirm that rent or mortgage, utilities, insurance, subscriptions and other regular mandates all appeared. Check annual or quarterly Direct Debits too; they are easy to forget because they may not collect during the first month.
Keep the switch confirmation until at least one full payment cycle has passed. If an organisation says it never received updated details, contact the new bank before recreating the mandate so you do not accidentally create duplicate payment instructions.
Frequently asked questions
Do I need to cancel my Direct Debits before switching?
No. Under a full CASS switch, existing Direct Debits are moved automatically. Cancelling them yourself can cause unnecessary problems.
How long does the switch take?
The Current Account Switch Service completes the switch in seven working days once the new account is open and the switch date is agreed.
What about a new Direct Debit set up just before the switch?
CASS advises not to create new payment arrangements on the old account during the final seven working days because they may not transfer.
Check less-frequent mandates after the first month
Monthly bills are easy to verify, but quarterly, six-monthly and annual Direct Debits can remain invisible for weeks after the switch. Use an old statement to list insurance, memberships, tax payments and other infrequent mandates, then tick them off when they first collect from the new account. If a company tries the old details and the payment is redirected, update the company directly so its records stop depending on the switching redirection. A full payment audit should therefore continue beyond the first successful week of the new account.

I would let CASS do the job it is designed to do. Manually cancelling and rebuilding every Direct Debit before a full switch usually adds risk rather than reducing it. The two points I would watch are the final seven-working-day window and the first payment cycle afterwards. Do not create new mandates on the old account during that period, and then verify the first collections on the new account. Keep enough money in the right place for bills that fall close to the switch date. If anything fails because of the switching process, go to the new bank with the exact payment details and use the Guarantee. A good switch should feel boring: payments move, salary is redirected, and after a month there is very little left to think about. I would also check annual Direct Debits such as insurance or memberships, not just monthly household bills. A successful first month does not prove that every less-frequent mandate transferred correctly. Keep the last old-account statement and the first two new-account statements together. They create a simple audit trail showing which mandates moved and when. If a payment is missing, contact the new bank with the Direct Debit originator, amount and expected date before setting up a replacement mandate. That reduces the risk of duplicate collections and makes use of the switch guarantee much easier.
