Flagstone Launches Maturity Rollover Tool to Eliminate Missed Interest‑Earning Opportunities for Savers

Flagstone Maturity Rollover has launched to automate the movement of savings upon maturity, allowing customers on the Flagstone savings platform to maintain continuous interest accrual. This interest rollover tool helps users avoid missing out on daily interest because their account transfers take longer than expected.

By opting into Flagstone’s reservation tool, known as ‘maturity rollover’, a customer’s savings are moved instantly from one account to another predetermined, ‘reserved’ account as soon as the first account matures. The service significantly reduces the likelihood that any of their money will miss out on the chance to earn further interest.

If a Flagstone saver leaves matured cash in the company’s holding account for just 40 days cumulatively per year, their potential interest income for the year drops by more than 10%. Maturity rollover erases the risk of this cash lying idle.

Since the functionality was first soft-launched and then officially launched this Spring, Flagstone clients have used maturity rollover to preserve continuous interest earning potential on £2 billion of savings. Since January 2025, 2,400 Flagstone savers have reserved future accounts every month.

To date, 81% of savers using maturity rollover have reserved fixed term accounts. Only 12.5% have chosen instant access accounts and 6.7% have chosen notice accounts. Among those choosing fixed term accounts, 44% have selected 3-month fixed accounts. Longer-term fixed accounts trail short-term alternatives: 6-month fixed accounts are selected by 22.7% and 12-month fixed accounts by 20.1%.

In addition to maximising interest earning potential, Flagstone’s maturity rollover tool was created to take the pressure off managing savings for people living busy lives. Now, cash management can work around savers’ lives. Whether they are on holiday, unwell, or under significant work pressure, savers can enjoy the flexibility and convenience of reserving new rates ahead of time, rather than hurrying to move money on an account’s maturity date.

“At Flagstone, we never want a single one of our savers to miss out on the chance to earn a single day’s interest. To that end, we’re enhancing product functionality that not only improves the customer experience, but influences systemic change in how all of us who save think about the money we save and what we expect to get back,” comments John Martin, Chief Product Officer at Flagstone. “The UK is in the grip of an inertia epidemic when it comes to savings – something has to be done.”

Analysis of Bank of England credit data finds that £1.3 trillion of UK savings are sitting in low interest savings accounts earning less than 50% of the Bank’s base rate. That equates to three in every four pounds of UK savers’ hard-earned cash.** Half (48%) of UK savers don’t know what interest rate they’re earning; nearly a third (29%) have used the same low interest savings accounts for more than 11 years, and one in eight (12%) rarely or never checks on the progress of what’s in their accounts.***

Martin continues: “Having chosen to save on a savings platform, Flagstone customers typically have an above-average interest in actively managing their money. Even so, the sums of cash left in our holding account prove to us that there was still a lot more to do to make the experience of saving more effortless and enjoyable. Automating the process of moving your money from one account to another in advance of the first one maturing was a natural next step and is proving hugely popular.”

The maturity rollover tool creates additional intelligence for Flagstone to support its customer-driven product development strategy over the longer-term. Martin concludes: “High adoption of maturity rollover by customers has been really illuminating. We can now see not only where customers want their money to go right now, but also the sorts of account terms, types and durations they will want a few weeks or months in advance. With this insight, we can work with our 65+ bank partners to optimise the selection of accounts on offer, a behind-the-scenes service that’s particularly important in a market where rates are steadily declining.

“This approach also reflects Flagstone’s commitment to the FCA’s Consumer Duty principles, ensuring our products and services deliver good outcomes across price, value, and ease of use. We’re proud to support our customers with smart, intuitive tools that give them greater control, clarity, and confidence in managing their money. At Flagstone, we’re always working to give our customers the best outcome.”
