Tandem was one of the first digital banks in the UK and offered automatic savings features to its customers. Since then, it has evolved with a mission to help 'consumers reduce their carbon footprint, save, borrow and spend a little bit greener' and has partnered with companies such as Oplo and Allium money.

In this review, we focus on Tandem Bank's savings products, but additional information on its other products can be found on the Tandem website.

What is Tandem?

Launched in 2015 by founders Matt Cooper, Michael Kent and Ricky Knox, Tandem was created to 'get you and your money moving in the right direction'. Tandem is a fully-fledged bank account which means that up to £85,000 of your money is protected by the Financial Services Compensation Scheme (FSCS). Tandem became a fully-fledged bank account in 2018 after it acquired Harrods bank, allowing it to operate from the previous licence that Harrods Bank held.

Tandem was previously best known for its innovative savings features where it used artificial intelligence to analyse your spending habits and suggest an amount for you to save. Users could also save money using its handy round-ups feature, however, in January 2021, Tandem announced that it was stopping its autosaving features to concentrate on other projects including a focus on 'green banking'. Tandem announced in 2022 that it was 'acquiring fast-growing consumer lender Oplo to create the UK’s fairer, greener digital bank.'

How does Tandem work?

Currently, Tandem offers 1, 2 or 3 year fixed savings accounts, as well as an Instant Access account.

To join Tandem you just need to download the app from the App Store for iPhone, or Google Play Store for Android and register for an account. You are required to enter your Title, First and Last name as well as an email address and finally a secure password.

The next step is to enter your mobile number, this is required so that Tandem can send you a unique 6-digit code. Tandem then asks for further personal details including your date of birth, nationality and address. Finally, you'll need to enter your current account details so it can connect to your account.

Alternatives to Tandem

In the below comparison table, we highlight the key differences between Tandem and some of its competitors. Tandem closed its autosaving features in 2021 to focus on greener banking so if you are looking for money management features in a digital bank then you may wish to look at the apps in the following comparison table.

Is Tandem safe to use?

Tandem is a registered bank which means that your money is protected up to £85,000 with the Financial Services Compensation Scheme (FSCS). This limit applies to all money you may have with Tandem across different accounts, therefore if your savings exceed the value of £85,000, anything over the threshold will not be protected.

Tandem also advises that your bank details are safe with them as they use encryption software to keep your personal information safe.

Tandem Bank customer reviews

17% of users rate Tandem as 'Bad' with users claiming 'bad support'. Some users also express dissatisfaction with the bank relating to lost transactions and problems with ID verification. Some customers have also recently commented on their accounts being locked due to Tandem being unable to contact them to review the account.

Pros and cons of Tandem Bank

Pros of Tandem Bank

  • Free
  • Easy to set up
  • Committed to green banking and helping customers reduce their carbon footprint
  • Competitive savings rates
  • FSCS protected
  • Chat to customer services 9am-5pm Mon - Fri

Cons of Tandem Bank

  • The only way to access it is via an app on your mobile
  • Limited banking features
  • Does not offer a current account


Overall, Tandem's appeal has diminished since it no longer offers credit cards or autosaving features to customers. Tandem says it is currently working on something new and hopes to reintroduce a spend feature at a later date. For now, the Tandem savings accounts offer competitive rates (although not market-leading) and your money is protected up to £85,000 by the Financial Services Compensation Scheme.

Tandem will no doubt be a good fit for some and particularly those looking to earn a good rate of interest on their savings but for now, there is a little way to go to rival other app-only banks and savings apps such as Starling Bank, Monzo, Chip and Plum.
