Starling Bank account switching: CASS, payments and checks

Omar KhanUpdated 2026-09-2810 min read

Quick answer

Starling uses the standard seven-working-day Current Account Switch Service and moves eligible payments and payees before closing the old account. The useful preparation is to identify anything CASS does not migrate automatically, especially third-party permissions and linked savings arrangements. Starling says CASS moves the balance, Direct Debits, standing orders and saved payees, with incoming payments to the old account redirected after completion.

A full CASS switch is deliberately mechanical, but your finances are not. The service can move many regular payments and close the old account; it cannot decide whether the new account is good value or whether a linked service outside the current account needs attention. For this page, that framework is applied specifically to Starling Bank switching offer and CASS 2026: fees and Direct Debits.

Choose the switch type and prepare the old account

First decide whether you want a full CASS switch or simply a second account. A full switch normally closes the old current account; keeping both requires a different approach. Starling says CASS moves the balance, Direct Debits, standing orders and saved payees, with incoming payments to the old account redirected after completion. Do not start the process until you are comfortable with the old account disappearing on the completion date.

Use the live Starling Bank page for the final figure rather than assuming the number in this guide will remain unchanged. In this article, apply that check to Starling Bank switching offer and CASS 2026: fees and Direct Debits.

Prepare the old account as if it were changing address. Clear unexplained pending card payments, download statements you may need, and make sure personal details match at both banks. If the old account is overdrawn, work out how that debt will be repaid rather than assuming the new bank inherits it.

For a fair comparison, change only one variable at a time. Keep the same balance, transaction count, borrowing amount or holding period when you compare Starling Bank with an alternative; otherwise the cheaper-looking result may simply come from different assumptions.

What CASS moves and what still needs manual attention

CASS is designed to move the core current-account plumbing: the balance and many regular payments. Third-party provider permissions do not automatically migrate. Starling also notes that some linked products, such as an open Starling Cash ISA when switching away, can affect whether a CASS switch can proceed. That automation is valuable, but it is not a reason to stop checking. Keep a list of salary, benefits, important Direct Debits and annual subscriptions so you can verify them afterwards.

Some relationships sit outside the switch. Open Banking permissions, merchant card subscriptions, linked savings, investment services and finance agreements may need separate action.

Timing, incentives and the first week after the switch

If Starling Bank is offering cash or another incentive, read the offer as a separate contract. The full switch normally completes in seven working days and closes the old current account. Note every deadline and exclusion. A switch can complete successfully while the incentive fails because one pay-in, Direct Debit or app-login condition was missed.

Choose a completion date that avoids the day before rent, mortgage, payroll or a major annual bill. Seven working days is predictable; your merchants are not. Leaving a few quiet days around the switch makes it easier to spot a payment that did not behave as expected.

Statement checks, evidence and final closure controls

Worked example: If a budgeting app reads your old bank through Open Banking, assume that permission must be re-established after the switch. Put it on the checklist instead of discovering the missing feed on payday. The point is to compare temporary value with the permanent economics of the account. If the ongoing fee, overdraft cost or service model is wrong for you, a one-off payment rarely fixes that for long.

MYBANKANSWERS VERDICT

Omar Khan - Editorial view

Use CASS for convenience, not as a substitute for choosing the right account. With Starling Bank, the switch itself is the easy part; the work is checking overdrafts, linked services and the economics after any incentive. I would not move a long-standing main account for a bonus unless the destination account would still be acceptable with the bonus set to £0. Applied to Starling Bank switching offer and CASS 2026: fees and Direct Debits, the final check is whether the product still works when its temporary promotion is removed.

Starling Bank: Switching guidance prioritises the bank’s current offer terms and Current Account Switch Service material. Incentives, exclusions and account fees can change during 2026.
