Flagstone, the UK’s largest savings platform* handling £19.6 billion of individual and business savers’ cash, has posted another year of record revenue growth, with total income increasing more than 350% over the past three years.
Accounts for the year ending 31 December 2025 show Flagstone generated £61.8 million in revenue, a 16% year-on-year increase (2024 revenue: £53.4m) and 358% higher than total revenue for 2022 (£13.5m).
On top of surging revenues, Flagstone recorded 21% year-on-year increase in assets under administration (AUA) ending 2025 with £18.8 billion, as well as sustained profitability for a third consecutive year.
Additionally, Flagstone customers generated cumulative returns of more than £600 million on their savings on the platform during 2025.
‘Our 2025 results mean Flagstone has started 2026 from an enormously exciting position of strength’, says Arman Tahmassebi, CEO of Flagstone. ‘Over the year, demand for Flagstone grew sharply as more individual investors and business finance leaders discovered our platform and were quick to see the value of cash as an asset class in its own right.’
Faster than ever, cash is earning its place as the right home for the money you don’t want to see locked up in underperforming, risk-laden, or years-long investments.
Direct to Consumer platform userbase surges by 51%
Flagstone’s consumer platform continued to grow strongly as savers continued to take a more active approach to managing their cash. During 2025, the number of non-advised individual customers on the platform grew 51% and the total assets they hold rose by 37%.
81% asset growth among direct business savers
2025 growth was significantly underpinned by a particularly strong adoption of Flagstone’s digital cash management platform by UK businesses, the vast majority of whom found Flagstone through recommendations and word of mouth. Cash directly deposited by UK SMEs increased by 81% and by the end of the year, 7,500 UK businesses’ assets accounted for more than a quarter of Flagstone’s total AUA.
‘For years, cash reserves have been a millstone round my finance team’s neck. It’s a pool of money that took time and effort to manage and keep safe without really benefitting our bottom line,’ says Neil Barnett, Finance Director of The Nursery, a Flagstone business customer.
We’re now earning upwards of 3.5% on our cash reserves, spreading them more securely between accounts and banks, all while retaining instant access to almost all of the funds at any time and managing them from one single location.
Flight to instant access accounts, despite falling base rate
Over the course of 2025, individual and business customers alike signalled their appetite to keep cash holdings accessible. Demand for readily-available cash grew significantly through the year and by year-end 63.2% of consumer and 57% of business assets were held in instant access or easy access accounts. For comparison, at the end of 2024, these proportions had been 47.6% and 32.7% respectively.
‘When the Bank base rate started its current downward trajectory, the market was quick to assume that savers would want to lock in whatever they can,’ Tahmassebi continues.
‘But users of the UK’s largest savings platform have proven that assumption wrong. Savvy Flagstone savers appreciate high-paying fixed rates, but they want to keep a significant portion of their cash handy too in case needs arise, and we help them achieve both those goals in one single place.
‘Banks are continuing to compete hard to satisfy this customer demand for high performing instant access rates with the margin between instant access rates and fixed term rates remaining as tight as it has been for many months.’
Investment to expand product range to ISAs
Profits achieved from the company’s record revenue generation are continually reinvested in product development and brand expansion. In February 2026, Flagstone launched its first Cash ISA product, bringing a new kind of tax wrapper to the consumer savings market - one that allows complete flexibility to transfer in, manage and move your tax-free savings all in one place.
The Flagstone Cash ISA is currently supported by six UK banks including Oaknorth, Paragon and Ratesetter (Metro Bank) who each offer Cash ISA products on the platform. Additional banks and products will be added to the wrapper over the course of the year.
‘As demand for Flagstone grows, we’re committed to bringing to market the products and services our customers need and want from us,’ concludes Tahmassebi.
‘Whether you’re young or old, whether you want to save more for the long-term, or whether your goal is just to keep your money working hard and protected under FSCS rules while you wait for a great investment opportunity, Flagstone has a lot to offer. We exist for anyone who’s prepared to wake up cash - their own, or that of their company - and actively manage it for maximum interest with minimum risk.’
