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

Frequently asked questions
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.
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.
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.
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.
