Atom bank is one of the UK “challenger banks” aiming to bring banking into the present. Atom works entirely through your smartphone or tablet, making banking more accessible. However, unlike many of its digital banking peers (such as Monzo or Starling), Atom offers savings accounts and mortgages rather than current accounts. It also offers business loans.
What is Atom bank?
Atom bank was one of the first wave of UK challenger banks, launching in 2016. It sees no need for physical branches, providing all of its services from the app. Atom’s strengths are value for money and convenience, and it has won praise for how easy it is to use. Atom doesn’t offer any current accounts – only savings and mortgages, as well as business loans.
The bank offers an Instant Saver account, as well as an Instant Saver Reward account that pays a higher rate of interest during the months you don’t make any withdrawals. It also offers a variety of fixed rate savings accounts and a cash ISA.
Atom’s fixed rate savings accounts
Atom has a range of “Fixed Saver” accounts to choose from. The terms of these fixed rate savings accounts vary in length from 6 months to 5 years. You’ll need to leave your money in the account for the agreed term length, and it will earn a fixed rate of interest over that duration.

How we picked these
How easy is it to top up an Atom account?
Very easy. You simply add funds via the app from your connected bank account. You can transfer up to £100,000 to your Atom savings account, with a £200,000 limit applying across all accounts you hold with the bank.
If you are opening a Fixed Saver account, you must deposit your money within a week of opening the account and no further deposits can be made.
You can add money to an Instant Saver or Instant Saver Reward account whenever you like. This also applies to Atom’s cash ISA, but you can only pay up to £20,000 into a cash ISA in the 2026/27 tax year – this is dropping to £12,000 from April 2027 for those under 65 (the remaining £8,000 of your allowance can be paid into a stocks and shares ISA). Note that Atom bank doesn’t currently accept ISA transfers.
How does Atom bank work?
You access Atom through an app on your tablet or smartphone. Atom doesn’t even send a card, you just move your money via bank transfers.
The basic app functions include:
Your savings: See how much money you have saved, and how much money you will earn through interest. Your interest rates are also displayed on the screen.
Your documents: All your account documentation is stored safely within the app.
Atom’s products: Atom offers a variety of savings accounts, as well as mortgages at a competitive rate. From the products screen you can select or apply for one of these options.
Your mortgage: If you have a mortgage with Atom, you’ll be able to view your repayments on screen. This will let you know how much and when you need to pay back your loan. Read our Atom bank mortgage review to learn more.
Business loans: Atom offers business loans available through intermediary brokers.
Help and support: Check out the FAQs, use the live chat feature or phone Atom Bank directly from the app. You can also provide feedback or start a complaint there.
How safe is Atom bank?
With an emerging bank like Atom, you might worry what will happen to your money if the bank goes bust. Atom is covered by the Financial Services Compensation Scheme (FSCS). So you’re covered for up to £120,000 if Atom suddenly went insolvent.
You might also have concerns about the bank’s day-to-day security features – how effective is the bank at stopping fraud? Well, it offers broadly the same security features as a traditional banking app. As well as a passcode, Atom bank uses face and voice recognition to keep your money safe. When you log in, you’ll need to provide either a selfie, passcode or voice clip.
Can Atom be used abroad?
Atom has no option for a current account, meaning you may want to look elsewhere if you’re after for a mobile-based bank account to travel with. Additionally, while you can access the Atom app while overseas, or even open an account, you might struggle to get updates.
In the App Store, the Atom banking app scores 4.8 out of 5 stars, from more than 68,000 reviews. Over at the Google Play store, it also gets 4.9 out of 5 stars, from over 19,500 reviews.
On Trustpilot, Atom has 4.8 out of 5 stars and a rating of “Excellent”, based on over 20,000 customer reviews. Positive reviews praised the app’s simplicity and ease of use, while negative feedback mentioned technical issues and specific problems with in-app face recognition.

Our verdict
Atom Bank has a good range of savings accounts to choose from, the set up is fairly quick and the rates are competitive (although not always the top of the market). With a fixed rate account, can choose how long the account lasts for and whether to get interest paid monthly or annually.
Just keep in mind that once you deposit your money in a fixed rate account, you won’t be able to get it back until the account term expires – Atom has no “cooling off” period, so think carefully before opening an account.
You can open a fixed rate account with as little as £50 and still get Atom’s best rates. Easy access accounts have no minimum deposit. Together with its flexibility and easy set up, this makes Atom a competitive option for small savers who want to grow their stash without touching it for a while.
