Launched in 2016, Atom bank is a relatively new ‘challenger bank’. It is entirely app-based, operated from your smartphone or tablet. It promises to be a simpler and more customer-centric bank. Atom bank offers fixed-term savings accounts, mortgages and business loans – there are no current accounts.

What is Atom bank?

‘Born digital’

Atom bank’s CEO, Mark Mullen, describes Atom as ‘a new kind of bank – it’s a bank that was born digital’. Atom is an app-only bank. Without branches, your accounts are operated exclusively via the Atom bank app on your smartphone or tablet. It is technological, streamlined and accessible – modern banking. is their Strategic Board Advisor – it doesn’t get much more modern than that!

Atom bank does not offer current accounts. It offers Fixed Savers and mortgages. Because it has no branches, overheads are kept low, enabling Atom to offer competitive rates.

How Does Atom Bank Work? 

The app

You will need to download the Atom bank app on your smartphone or tablet. The Atom Bank website has lots of information, but you’ll need the app to apply for its products. You can also browse Atom’s products on the app.

Once downloaded, you will see that the Atom bank app is simple and user-friendly. The home screen is referred to as ‘Your Hub’, from which you’ll access the various app functions.

Basic app functions:

Join Atom – this is where you register in the app. To register, you will need to provide your name, email address and mobile number; these are used to set up your customer record. Atom bank utilises biometric data for log-in security – you will, therefore, be asked for your photo and a recording of your voice.

Browse our products – this takes you to Fixed Saver and Mortgages. Here you will find a summary of the products and how they work. From here, you can go on to view the available Fixed Savers or ‘Call Us’ for more about Atom bank’s mortgages. 

Atom Info-motion – Atom has put together 3 short info-motion videos explaining their ‘story so far’, ‘opening an account’ and ‘keeping things secure’ to cover some key FAQs. 

Fixed Saver (Demo account) – this is a neat little feature which allows you to preview what a live account looks like. You can swipe and click through this demo account to see how your account information and notifications will be presented.

Enter a code – you may be sent codes to check the progress of your mortgage. Enter them here.

Hints and tips – a handy user guide for the app.

The other main area of the app is called The Portal. The Portal is where you’ll manage your account settings. You can personalise your app, changing the name and look of your accounts.

The Portal:

My Profile – choose your name and colours.

Vault – this is where your account documentation e.g. statements, terms & conditions and certificates will be stored securely.

Settings – choose how you log in.

Help & Support – access 24/7 support.

How to complain – complaints procedure and address.

Feedback – this takes you to UserZoom where you can let Atom bank know how well they’re doing.

Atom bank is committed to transparency and simplicity. Its aim is to offer ‘very few products, very simple products’.
