What are business Instant Access savings accounts?
Instant Access savings accounts pay you interest on your business’s cash reserves, while allowing you to access your funds whenever you need them.
Because of this flexibility, interest rates are typically lower than with Fixed Rate business savings accounts, where your money is locked away for a set period.
Can I open Instant Access savings accounts for my business?
Yes. You’ll need to deposit a minimum of £100,000 to join Flagstone for Business. You can split your deposit across different account types – including Instant Access, Fixed Rate, and Notice savings accounts for business.
Can I withdraw anytime from an Instant Access business savings account?
Yes, you can withdraw money any time for free.
You can move your cash into different accounts in the Flagstone platform, or withdraw them to your nominated business current account.
