How does the Current Account Switch Service work?

CASS moves everything from your old bank account to your new one — including your balance, direct debits, standing orders, and salary. It completes in 7 working days. You choose a switch date and the service handles everything. Any payments sent to your old account are automatically redirected to your new one for 3 years (extended to 36 months from the switch).

Is it safe to switch bank accounts?

Yes. The Current Account Switch Service comes with a guarantee: if anything goes wrong during the switch, you'll be refunded any interest or charges you incur as a result. Over 10 million switches have been completed since CASS launched in 2013. It's backed by the major UK banks and overseen by Pay.UK.

Will switching banks affect my credit score?

Switching banks itself does not affect your credit score. The new bank may do a credit check when you open the account (a soft or hard search depending on the bank), but the switch process doesn't impact your credit file. Your direct debits and payment history transfer seamlessly, so there's no interruption to payments.

Can I switch to any bank?

You can switch between any banks and building societies that participate in CASS — which includes virtually all major UK banks (HSBC, Barclays, Lloyds, NatWest, Santander, Nationwide, etc.) and many newer banks (Monzo, Starling, Chase). Check currentaccountswitch.co.uk for the full list. Some basic bank accounts and packaged accounts may have restrictions.
