Raisin is not a savings account rather a platform that connects you to savings acounts. If you are constantly looking to move your money around to get the best interest rates for your cash, Raisin is a good choice as they have a large range of savings accounts and a very easy-to-use website.

Yes, through the Flagstone platform, you can access hundreds of different high-interest savings accounts including instant access, notice, fixed-term, and Sharia accounts. Many of these accounts have excellent interest rates (some even have exclusive interest rates that can’t be found elsewhere).

Once you have an account with the company, you can spread your money out over many different savings accounts and banks without having to complete an application for each individual savings account. So, for example, if you have £150,000 to deposit, you could potentially put £50,000 with three different banks.

You can move, place, or spread your deposits 24 hours a day, seven days a week. However, it’s worth pointing out that there is no app for the platform at the moment – it can only be accessed through an internet browser.

In terms of customer protection, eligible deposits are protected up to £85,000 per depositor per UK bank (£170,000 for joint accounts). So, if you plan on depositing more than £85,000 with Flagstone, spreading your cash out over several different banks on the platform is sensible.

One drawback of Flagstone is that not all banks are on the platform. So, it doesn’t offer access to the whole market, but with 200+ accounts from 67 banks what Flagstone offers is substantially more than any other platform.

Another issue to be aware of is that it can take 24 hours (or sometimes longer) for your cash to be transferred from your holding account to your chosen savings account. So, you may miss out on interest for a day or two.

Pricing: Customers only see net prices, but there is no cost scale available on the website.

Market Access: Of all the savings platforms we test Flagstone offers the most bank account access.

Apps & Platform: No app and no issues with the simple-to-use website.

Customer Service: We got straight through on the phone when we had a question about ISA accounts. There is no live chat function, though.

Does Flagstone have an ISA?

No, Flagstone does not offer ISA accounts. But, as the minimum deposit on the Flagstone savings platform is £10,000, it's safe to assume that Flagstone caters to higher-value accounts that would quickly fall outside the ISA limits.

When we phoned Flagstone to test their customer service to ask about the availability of the ISA, they said they were looking at it but had no immediate plans to launch an ISA product.

Is Flagstone safe?

Flagstone should be considered trustworthy. The company is authorised by the Financial Conduct Authority (FCA) under the Payment Service Regulations 2017 for the provision of payment services. Meanwhile, all the UK-based banks and building societies on its platform are members of the Financial Service Compensation Scheme (FSCS). So, eligible deposits are protected up to £85,000 per depositor per UK bank (£170,000 for joint accounts).

How much does Flagstone charge in fees?

With Flagstone, there is no fee to open an account. There are also no ongoing administration or management fees.

As for how the platform makes money, it uses a 'share of interest' model where it takes a small cut of its partner banks' interest rates (up to 0.30%). However, this is deducted before any rates appear on the platform so the rate that you see will always be the rate that you receive.

To put that in perspective, if you save the minimum deposit required open a Flagstone account (which is currently £10,000) you will lose out on £30 in interest per year. But as Flagstone only shows the net rate (the rate you will receive) it doesn;t feel like a charge but it is.

So, in theory, you can earn more interest by going to the provider directly; the disadvantage of this, of course, is that you have to open up lots of different savings accounts. So you are sacrificing (paying) a little bit for the convenience of having lots of different savings accounts and providers in one place.

Flagstone savers receive over £500m interest in 2024

In February 2025 Flagstone reported record-breaking results for 2024, as more savers turned to cash deposits to secure inflation-beating returns. The company’s revenues surged 46% to £55 million, marking its second consecutive year of profitability, while assets under administration (AUA) soared 49% to £16.2 billion.

Flagstone customers collectively earned over £500 million in interest on their savings in 2024, highlighting a shift in how UK consumers are managing their cash. With inflation remaining a concern and investment taxes increasing, more savers sought out competitive interest rates rather than leaving money in low-yielding traditional accounts.

CEO Simon Merchant attributed the platform’s success to the changing economic environment. “In 2024, managing money required careful navigation of inflation, fluctuating interest rates, and significant tax hikes,” he said. “Many savers took proactive steps to ensure their cash worked harder for them.”

Flagstone’s direct-to-consumer (D2C) user base expanded by 55% last year, reflecting growing consumer awareness of the benefits of diversifying savings across multiple accounts. The number of banks on the Flagstone platform increased to 66, offering over 220 savings accounts, ensuring customers had access to consistently competitive rates. As of January 2025, 95% of rates on the platform exceeded the market average, with over a third of available accounts offering returns of 4% AER or more.

Beyond individual savers, Flagstone also saw increasing demand from financial institutions looking to integrate its platform. More banks and fintech firms have partnered with Flagstone to offer enhanced savings products to their customers, taking advantage of the platform’s streamlined technology and data insights.

Flagstone continued to enhance its user experience in 2024 by revamping its Know Your Customer (KYC) process, reducing friction for new customers and improving onboarding efficiency. The company also upgraded its banking partner portal, allowing financial institutions to better track how savers interact with their products.

Looking ahead, Flagstone is focusing on automating more of the savings process, enabling customers to seamlessly move their money into higher-yielding accounts. Following a £108 million investment from Estancia Capital Partners, one of the UK’s largest fintech investments last year, the company is well-positioned for further growth in 2025.

With the UK savings market valued at £1.5 trillion, but much of it earning 2% or less in interest, Flagstone sees a significant opportunity to help more savers achieve better returns in a rapidly evolving financial landscape.

Currently, the top savings interest rates offered on the AJ Bell Cash Savings hub are among the most competitive.

All accounts on the platform are covered by the Financial Services Compensation Scheme (FSCS) guarantee of up to £120,000 on bank deposits.

By comparison to the alternatives in our table, the AJ Bell Cash Savings hub is relatively limited.

Unlike the others, AJ Bell’s service does not offer any instant access savings accounts, from which savers can withdraw their money without incurring a penalty.

Fixed term savings accounts or bonds typically lock money away for a term of between six months and five years, with a set interest rate for that period.

Notice accounts require you to give a notice of between 30 to 90 days before withdrawing your money.

One point in favour of the AJ Bell Cash Savings hub is its simplicity. The large numbers of accounts offered by its rival comparison platforms can sometimes seem excessive and potentially confusing.

There are usually a few accounts in each category which offer better interest or conditions than the others, so having a wider range of options does not necessarily make a platform superior in all respects.

The hub offers a tool on its website which shows you exactly how much money you will earn in interest from each account when you allocate a set amount of money. Among its rivals, only Raisin offers a similar feature to those browsing their websites.

The main webpage of the hub also clearly summarises the most important information regarding each account: the interest rate, the term length and the minimum deposit. By contrast, Raisin requires you to do a bit more searching to see the minimum deposit.

The filter for the comparison page is also pleasantly simple, allowing savers to select accounts by four different ranges of term length. Its rivals present many more filters, which could be confusing for beginners.
