The latest data for Q3 2023 shows that seven in 10 (71%) switchers preferred their new current account to their previous one, with service-related, non-financial benefits continuing to be the main reasons end users preferred their new account.
Those who switched current account through CASS during Q3 2023 cited better online or mobile app banking (45%) and customer service (32%) as the top two reasons for preferring their new account. Following this, interest earned (31%) and location of branches (24%) came in as the third and fourth most important factors.

“It is particularly noteworthy that three new customers, Citibank, Allica Bank, and Rothschild, have joined the service this quarter, enabling greater choice for consumers and demonstrating the significance of the service.”
