Bank Switching Checklist: Before, During and After
A bank switch is easiest to manage when it is treated as a short project rather than a single button in an app. The new account must be suitable, the source account must be eligible for the chosen route, payment instructions need to move safely and any promotional conditions must be tracked independently. CASS simplifies a full switch, but it does not decide whether the destination account is good value or whether a cash incentive is worth the requirements. This checklist is designed to be used before the application, during the seven-working-day CASS window where applicable, and again after the first salary and bill cycle has completed.
Before applying, decide whether the destination account is worth keeping
Begin with the account rather than the bonus. Write down the monthly fee, overdraft pricing, cash and branch access, card use abroad, support channels, joint-account needs and any recurring rewards. Then convert the recurring items to an annual figure. A £5 monthly fee is £60 a year. If a reward is worth only £3 a month to your normal behaviour, that offsets £36, not the maximum amount in the marketing example. The destination should still make sense once the one-off switching payment is removed.
Check account-opening eligibility separately from switching eligibility. The bank may require age, residency or identity evidence to open the account, while the promotion may require a full CASS switch, a minimum pay-in, a set number of Direct Debits or no recent bonus from the same banking group. Save the offer terms on the day you apply. A later version can have different deadlines or exclusions and is poor evidence if a reward dispute arises.
If you use an arranged overdraft, resolve the destination borrowing limit before the switch. The old overdraft does not automatically move. Also review linked products that could be affected by closing the source account, such as a regular saver, reward arrangement or fee waiver. Add any lost value to the switching ledger rather than treating the old account as economically empty.
Once the account is open, choose the switch date carefully
For a standard CASS full switch, the agreed date must allow seven working days and cannot be a weekend or bank holiday. Look at the household calendar before choosing it. Avoid placing the switch immediately before rent, mortgage, council tax or a cluster of other essential Direct Debits if a later date is available. The system is designed to be reliable, but a small cash buffer makes any rare problem easier to manage.
During the seven-working-day window, avoid setting up new payment instructions on the old account unless the bank confirms how they will be handled. CASS guidance notes that new arrangements created too close to the switch date may not be transferred. If a new bill must be created, set it up on the destination account where possible and record the first collection date.
Keep the old debit card available until the agreed switch date, but identify recurring card subscriptions that use its card number. CASS transfers account-based payment instructions, not the card credentials stored by every merchant. Streaming services, transport apps and online subscriptions may therefore need a direct card update after the new card is active.
Inventory salary, Direct Debits, standing orders and important payees
Make a payment inventory from at least one recent month of statements. Include salary or benefits, Direct Debits, standing orders, regular incoming transfers and important payees. Mark which items are essential and which can tolerate a delay. This list gives you a post-switch control sheet. It also reveals old or dormant payment instructions that you may prefer to cancel rather than migrate blindly.
CASS normally transfers regular incoming and outgoing payments and the old account balance, and payments sent to the old account are redirected after the switch. Even so, verify the first real cycle. Check that salary arrived in the new account and that the largest Direct Debits were collected once, on the expected dates and for the expected amounts. If a payment fails because of the switching process, contact the new bank promptly under the guarantee rather than improvising several replacement payments.
Saved payees may also transfer under the service, but old statements and transaction history are not the same thing as a migrated payment instruction. Download any statements you may need for tax, proof of payment, budgeting or a future dispute before access to the old account changes. Keep them securely rather than relying on indefinite online access after closure.
Track the promotion on a separate dated checklist
A switch can complete perfectly and still earn no bonus if the promotional conditions are missed. Create a second checklist containing every offer-specific action and its deadline: full CASS completion, required Direct Debits, salary or other funding, debit-card transactions, app login, account type and any exclusion for previous customers. Mark each item only when there is evidence, not when you intend to do it.
For an illustrative example, suppose the bonus is £180 and the destination costs £5 a month. The fee removes £60 over twelve months, leaving £120 of first-year value before recurring rewards or lost benefits. If a required Direct Debit is missed and the £180 is not paid, the account immediately becomes a normal £60 annual cost unless its ordinary features justify that price. This is why the account decision and the promotion checklist should never be the same document.
Store the offer PDF, screenshot or confirmation email with the switch timeline. Record the application date, switch request date, completion date and date each qualifying action occurred. If the reward does not arrive by the promised window, the provider can assess a clear evidence pack instead of trying to reconstruct events from memory.
After the switch, verify one full cycle and review normal-year value
On the switch date, check the destination balance, old-account closure status and any message from the new bank. Over the next few weeks, tick off the first salary, major Direct Debits and standing orders from the inventory. Update recurring card subscriptions where necessary. If the old account held a small residual credit or charge, reconcile it rather than assuming the closure message proves every transaction was settled exactly as expected.
After the promotional reward arrives, run the account calculation again without it. Annualise the monthly fee, use realistic rewards and include overdraft or travel costs based on actual behaviour. This normal-year figure prevents a temporary bonus from turning into years of paying for an account that no longer fits. If the account still wins, the switch has improved the banking setup rather than merely generated a one-off payment.
BankOfferScout's editorial view is that a checklist should reduce operational risk without encouraging unnecessary switching. The right destination is one that works after the incentive disappears. Use CASS for the payment move when eligible, use a separate promotion tracker for the bonus, and verify the first real payment cycle before considering the job finished.
BankOfferScout editorial view
For Bank Switching Checklist, BankOfferScout treats the complete qualification checklist and destination-account fit as the anchor. We compare the outcome around eligibility, deadlines, switching mechanics and the ongoing value of the destination account, because the largest headline figure is not automatically the feature that matters most in everyday use.
The editorial test for Bank Switching Checklist is whether the choice still works under normal behaviour. The strongest option is not necessarily the one with the loudest rate, reward or bonus. A better fit is the one that still works after allowing for missing a qualifying action or moving to a poor-fit destination account, with recurring costs and benefits translated into a common period.
Our editorial view on Bank Switching Checklist starts with practical fit rather than headline appeal. Treat the method on this page as durable and cash incentives, eligibility exclusions, pay-in rules, Direct Debit requirements, deadlines and account features as variable. Recheck those items at the provider switching page, incentive terms and destination-account tariff immediately before action, and use the Current Account Switch Service or another authoritative process source for any rule the provider does not control.
