How long does it take to get set up?
Most Flagstone accounts are up and running within a few hours, as long as we’ve got everything we need.
Sometimes it can take a little longer, but we’ll always ask for any information we need so you can get set up as soon as possible.
Once your account is open, you'll never need to apply for a business savings account again.
Will I have to do anti-money laundering checks for every new savings account I open?
No, we only carry out these checks when you first open a Flagstone account. Once you're set up with us, you can instantly open any business savings account in our platform – no additional checks required.
Do I have a direct relationship with the banks or just Flagstone?
Your relationship is with Flagstone. We liaise with each partner bank on your behalf and keep you informed about every account you hold.
What banks does Flagstone partner with?
We partner with over 40 trusted banks, including high street and challenger banks. When you join Flagstone, you’ll get access to 250+ FSCS-protected business savings accounts.
You can see most of our partner banks on our rates page. Once you’ve created an account with us, you’ll be able to view all available banks.
When can I expect to receive my money after I withdraw it from Flagstone?
We usually process withdrawals from your savings accounts in real-time.
Funds from your Flagstone holding account should arrive in your nominated account within one working day, but this can vary depending on the processing times of the banks.
