What Is the Current Account Switch Service (CASS)?
CASS is the official system that helps you switch bank accounts in the UK quickly and securely. It is a free, independent switching service operated by Pay.UK.
It moves your payments to a new current account and closes the old one in seven working days under a customer guarantee. Payments sent to your old account are redirected for a minimum of three years (often longer if needed).
More details at Current Account Switch shows more than 11 million successful switches have been completed since launch in 2013.
Before You Switch
- Pick an anchor account. Keep one long-standing current account open for continuity (useful for mortgage/lending checks).
- Choose your target offer. Check eligibility rules and any exclusions for existing customers.
- Open the new account. Most applications can be started and finished online or in-app.
- Line up easy Direct Debits. If you need two DDs to qualify, set up small ones first. Start here:
- Consider dummy/sacrificial accounts for future switches (e.g., Monzo, Starling, Chase spaces):
During the Switch (Step-by-Step)
Here’s the step-by-step of how to switch bank accounts UK CASS so nothing gets missed.
- Request the switch inside your new bank’s app (choose “Full CASS switch”).
- Select your completion date (you can set it in the future to suit your needs).
- CASS transfers everything: Direct Debits, standing orders, incoming salary/benefits, and your balance.
- The old account closes automatically on completion day.
You’re covered by the CASS guarantee if anything goes wrong.
After the Switch
- Double-check the first month’s bills and pay-ins. Redirection is in place, but it’s a good idea to take a quick look.
- Meet any bonus conditions (e.g., app login, debit-card spend, minimum pay-in).
- Track your money priorities.If you’re paying off debt, continue using the Debt Tracker Toolkit to manage balances, APRs, and due dates, so switching doesn’t derail your progress.
If you’re comparing multiple bonuses, see my live roundup:
- “My salary might get lost.” Incoming payments are redirected to your new account.
- “I’ll have to contact every company myself.” CASS moves your Direct Debits and standing orders.
- “If something goes wrong, I’m out of pocket.” The CASS guarantee requires the bank to rectify the issue and refund any charges/interest.
- Closing your only main account. Keep one “anchor” account for stability.
- Switching too often with the same bank. Some providers limit repeat bonuses.
- Missing small print. Many offers require a minimum pay-in, specific number of DDs, or a debit-card transaction.
Are the Bonuses Worth It?
Right now, most straight cash incentives cluster around £175–£200, with occasional higher returns when perks or cashback are added. Treat roughly £175–£200 as a sensible guide for typical single-offer switches, then view extras as a bonus rather than a given. MoneyWeek
