How Flagstone

makes money

For each account you open with our bank partners through Flagstone, we receive a small share of the interest. We deduct that share before we feature any account on our platform – so the rate you see will always be the rate you receive.

We don’t charge admin, management, or platform fees. 

 

This is how our share of the interest works →

Trusted by more banks

We partner with 40+ FCA regulated banks – more than any other business savings platform.

Your business savings are just the start

Manage your personal cash effortlessly with an individual or joint Flagstone account. 

What are Fixed Rate business savings accounts?

Fixed Rate savings accounts let you lock in a predictable interest rate for a set period. For example, you could fix an interest rate for one, two, or five years depending on the accounts you choose to open. You usually can’t access the cash reserves in a Fixed Rate business account until the term expires.  

Fixed Rate accounts typically offer higher interest than Instant Access alternatives, in exchange for restricting your withdrawals. 

Can I open a Fixed Rate business savings account with Flagstone?

With a minimum deposit of £100,000, you can open as many business accounts as you like in our savings platform. Flagstone gives UK businesses access to hundreds of accounts, all in one place.

You can split your deposit across different account types, letting you balance higher returns with liquidity.  

Are my business’s funds FSCS-protected?

All accounts in the platform benefit from FSCS protection on eligible deposits of up to £120,000 per client, per banking group. This means you can open multiple Fixed Rate business savings accounts and increase your FSCS protection, as long as the accounts are held with different banking groups.

You can see how much of your reserves are FSCS-protected at any time within the platform.

Can I close a Fixed Rate business savings account early?

Early withdrawals or account closures usually incur penalties, meaning your business could lose some or all of the interest you’ve earned.  

For this reason, Flagstone business users typically open multiple accounts with varying terms, giving them greater flexibility across their cash reserves. 

Are Fixed Rate business savings accounts worth it?

Fixed Rate savings can be a valuable addition to a wider business cash strategy, offering higher rates than those available with Instant Access or Notice accounts. If your business has surplus cash that’s not tied up in the short term, a Fixed Rate business savings account can offer a secure and predictable way to earn interest.  

 How much money should I keep in Fixed Rate business savings accounts?

The right amount for you will depend on your business’s specific needs. But it’s important to consider that your funds are restricted until the account matures. So, you may want to deposit your surplus cash into our Fixed Rate accounts, and deposit the rest into Instant Access accounts.  

With Flagstone, you can open and securely manage multiple business accounts. You can also monitor your earnings in our Cash Tracker feature, giving you a dashboard that makes reporting easy.
