The rates shown here have already had our share of interest deducted, so the rate you see is the rate you will receive. You can learn more about share of interest here. Rates correct as at 8 June 2023.

For Fixed-term deposit accounts, interest is calculated daily and paid at the end of the term. For details of how interest is paid on Instant access accounts and Notice accounts, please refer to the terms and conditions for the specific account available on the platform.

The minimum deposit for an individual is currently £10,000.

Different banks, accounts and rates will be available to you on the platform depending on whether you are an individual looking to open a joint account, or acting on behalf of a company, charity, trust, SIPP or SSAS. The number of accounts available may also be reduced depending on whether you live in the UK, consider the UK your permanent home, and other factors.

Frequently asked questions

How are you able to offer competitive rates?

As the UK's leading cash deposit platform, the volume of deposits placed with us, and the relationships developed with our partner banks gives us access to exclusive, best-in-class deposit rates for our clients.

What are Instant Access, Notice and Fixed Term accounts?

With Instant Access Accounts, you can deposit and withdraw your money at any time.

With Notice Accounts, you can withdraw your money in the future, by giving notice to the bank. For example, 30 days' notice means you would give the bank notice and withdraw your funds 30 days later.

A Fixed Term Deposit Account has a specific term (e.g. 3 months or 12 months). Once a Fixed Term Deposit Account is open and funded it cannot be broken until the end of the term.

This means that your cash is locked up in the account for the full length of the term, after which it automatically returns to your holding account with the interest that has accrued on the deposit.

How is my money protected?

All UK-based banks and building societies on our platform are members of the Financial Service Compensation Scheme (FSCS). This allows your clients to protect their savings by spreading their cash across several banks or building societies, and receive the FSCS protection of £85K each time (£170K for joint accounts), if eligible.

What are your fees?

With Flagstone, there are no admin or management fees to pay.

Rather than drain your savings with high fees, we use a ‘share of interest’ model instead. That means we take a small cut of our partner banks’ interest rates – up to 0.40%.

We deduct this before any rates appear on our platform – so the rate you see will always be the rate you receive.

Don't just store money, protect it.

Use our cash deposits calculator to see how much interest you could be earning, whilst FCSC protecting your deposits.
