What is a Fixed Rate business savings account?

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.  

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 cash that’s not needed 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 some of your cash into our Fixed Rate accounts, and 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.

Your business savings are just the start

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