What is Tandem Bank's best savings account with the highest interest rate?
The best savings account depends on what you want from your savings. If you're after fast access to your money, then an easy-access account should suit you. However, if you're happy to lock your money away for a time to access a higher rate, then a fixed-rate bond is a good option.
Finally, if you're looking to maximise your returns and shield them from income tax, consider an ISA. Below, we've listed the different types of accounts Tandem Bank offers, plus the highest interest rate currently available.

| Best cash ISA rate | 5.16% |

| Fixed bond terms | 1 year - 5 years |

What is Tandem Bank?
Digital challenger bank Tandem Money was created in 2014 with the aim of providing simple mortgage and savings products. It became a licensed bank in 2018 when it bought Harrods Bank, acquiring its banking licence in the process.
Tandem Bank merged with alternative lender Oplo in 2022 and the combined company now markets itself as a “greener, digital bank for all”.
All savings accounts are managed via the Tandem Bank smartphone app. The bank uses open banking technology to enable you to fund your Tandem savings account with an instant bank transfer without leaving the app.

Is Tandem Bank safe?
The actual app has several security features. All your details are held behind a password and, if you select the option, touch ID functionality. As a fully regulated UK bank, all deposits in customers’ savings accounts are protected, up to £120,000, by the Financial Services Compensation Scheme (FSCS).
This limit isn’t restricted to one account, but all deposit balances you have with Tandem. So you’re only covered for £120,000 of the total amount of money you have stored away with Tandem.
Tandem Bank and Oplo
In early 2022, Tandem Bank announced that it had acquired consumer lender Oplo. Oplo’s home loans can now only be secured through Tandem.

Tandem Bank currently offers a competitive range of fixed-term accounts and a fairly decent instant access savings account, plus cash ISAs. Read our savings reviews to see how it weighs up against other savings providers and check if it’s the right choice for you.
