British savers missing £12bn yearly by staying with same bank

Most British savers have never left their bank. According to research from Hargreaves Lansdown, nearly two-thirds have stayed with the same institution for more than a decade. That loyalty, whether born of habit, comfort, or simple inertia, is costing them dearly. The firm estimates that staying put costs British savers around £12 billion in missed interest every year—money that could be reclaimed by moving to a competitor offering a better rate or a switching bonus.

The math is straightforward enough. Five or more banks are currently competing for new customers with incentives, the largest of which reaches £220. Beyond the bonus itself, savers who move often discover they can earn substantially higher returns on their deposits. Yet something keeps people rooted. A survey of 3,000 British adults conducted in August found that only 34 percent had moved their money in the previous 12 months. The rest remained where they were, collecting interest at rates that rivals would happily beat.

Simon Belsham, chief client officer at Hargreaves Lansdown, frames the problem plainly: doing nothing feels easier, but it almost always leads to poor returns. Banks benefit enormously from this passivity. Millions of savers sit with their money by default, generating no friction, no administrative burden for the institution—and no incentive to offer competitive rates. The inertia is worth a fortune to banks. For savers, it is worth billions in foregone pounds.

What stops people from switching? Sarah Coles, head of personal finance at AJ Bell, points to a paradox: people are intensely loyal to their banks, which is precisely why competitors must offer sweeteners to pry them loose. Once a customer moves, the new bank gains what Coles calls a "captive audience," more likely to purchase other products and services. The switching bonus, she cautions, should be the cherry on top of a decision, not the whole reason. Savers ought to weigh the bank's reputation for service, any overdraft charges, and the savings rate itself.

There are practical obstacles too. Many switching deals come with conditions—a minimum deposit in the first few weeks, or a minimum number of direct debits leaving the account. More significantly, switching appears on your credit report, and lenders examine that record when deciding how much you can borrow for a mortgage. Opening multiple accounts in quick succession could damage your score, though closing an old account may actually improve it. Anyone planning to apply for a loan or mortgage within the next year might sensibly wait until the deal is done before switching.

The mechanics of moving, however, have been simplified. The free Current Account Switch Service, or CASS, is available through over 50 UK banks and building societies. You tell your new bank your chosen switch date—allow seven working days—and provide your old account details. Behind the scenes, CASS transfers payments, moves your balance, and redirects incoming money like salaries or benefits. Your old bank closes the account. If anything goes wrong, you are refunded any interest or charges made on either account. The one catch: recurring card payments, such as subscriptions, must be transferred manually. And old bank statements will no longer be accessible after the move, so downloading them beforehand is wise.

The barrier, then, is not logistics. It is psychology. People stay because they have always stayed, because switching feels like effort, because the status quo is comfortable. Yet that comfort costs them hundreds of pounds a year, and billions collectively. The banks know this. They are betting that most savers will not move, that loyalty and inertia will hold. The question is whether the promise of better rates and a modest bonus will finally be enough to break the spell.
