Mortgage Deals Drive 41% of Bank Account Switches During Home Moves, CASS Research Reveals

New data from the Current Account Switch Service reveals a significant engagement gap in the UK banking sector, as consumers consistently deprioritise financial restructuring during major life events. Despite the potential for better mortgage rates and budgeting tools, most home movers overlook their banking arrangements, presenting a persistent challenge for providers seeking to capture high-value customers.

What was announced

A survey of 2,000 UK adults who have moved home within the last two years found that while 53% of consumers spend an average of five hours researching their move, only 22% look into current accounts or banking options. This sits in stark contrast to the 50% who researched local property prices and the 48% who compared energy and broadband providers. The research suggests that bank account switching remains a low priority even when consumers are making significant financial commitments.

The data highlights a sharp generational divide in switching behaviour. Younger movers are significantly more proactive; 50% of those aged 18 to 24 and 51% of those aged 25 to 34 reviewed their banking options during a move. This resulted in 22% of the 18 to 24-year-old demographic actually completing a switch. Conversely, 67% of over-55s stated they would not normally consider reviewing their bank account during a move, with only 8% in this age bracket following through with a switch.

For those who did choose to switch, the motivations were primarily financial. Among mortgage holders who moved banks, 41% did so to access better mortgage rates, while 30% were motivated by mortgage-related incentives. Beyond lending, 28% switched to secure higher interest rates on deposits, and 29% sought better budgeting or money management tools. Despite these tangible benefits, 58% of all home movers failed to even consider a new banking provider during the process.

"Moving home is one of life’s more stressful milestones, and at a time when every pound counts, consumers need to be unlocking all the help they can get. With rates well above the low figures of a few years ago, taking time to compare current account options alongside mortgage arrangements can make a real difference, as could extra interest on your deposit, improved financial planning tools and tailored mortgage advice. As the backbone of your finances, you should take your choice of banking provider seriously and ensure your current account is meeting your needs and goals. If you decide to switch, it won’t add any burden or cost. You simply pick a new bank or building society, request a switch, and we’ll do the rest within seven working days. It could be the easiest move you make!"

The companies involved

The Current Account Switch Service (CASS) is the UK’s primary mechanism for facilitating the transfer of personal and small business bank accounts. Launched to increase competition in the retail banking market, the service provides a guarantee that switches will be completed within seven working days, handling the transfer of all direct debits, standing orders, and balance movements. It is designed to remove the perceived "hassle factor" that historically prevented consumers from leaving incumbent banks.

The service is owned and operated by Pay.UK, the country’s leading retail payments authority. Pay.UK is responsible for the infrastructure behind several of the UK's most critical payment systems, including the Bacs Payment System, the Faster Payment System, and the Image Card Clearing System. By managing these platforms, Pay.UK ensures that billions of pounds move safely between individuals and businesses every day. The organisation plays a central role in the UK fintech ecosystem by setting the standards and rules that govern how money is moved, aiming to foster innovation and maintain stability across the national financial network.

What FF News has reported before

FF News has closely followed the evolution of Pay.UK and the broader landscape of UK consumer finance. Recently, we noted that Pay.UK Bolsters Board with Tech Leaders from Monzo, Equals Group, and Bank of Ireland UK, a move intended to bring digital-first expertise to the nation's payment infrastructure. This leadership shift comes at a time of high activity for the operator, as Direct Debit Hits Record 5 Billion UK Transactions as Recurring Payment Dominance Continues, underscoring the scale of the systems Pay.UK manages.

The challenges of financial literacy and administration have also been a recurring theme in our coverage. We previously reported that School Leavers Struggle with Financial Admin as 31% Lack Confidence in Managing Money, which aligns with the CASS findings regarding the lack of engagement during major life transitions. Furthermore, the economic backdrop remains strained, as Two-Thirds of Brits Face Financial Pressure as Summer Socialising Costs Surge, making the potential savings from bank switching more relevant than ever for the average consumer.

What this means

The persistent inertia in the UK banking market suggests that "frictionless" switching services like CASS are only half the battle. While the technical barrier to moving accounts has been lowered, the psychological barrier remains high. For the fintech sector, the data confirms that the home-buying process is a critical but under-utilised acquisition window. The stark age divide indicates that traditional high-street banks are at risk of a slow-motion exodus; as younger, more mobile consumers age into higher-value mortgage products, their willingness to switch providers could erode the long-term stability of legacy deposit bases. The industry must now ask whether current account benefits are being marketed effectively enough to compete with the immediate concerns of energy bills and broadband speeds.
