Our 2025 financial year at a glance

16 July 2025


An overview of the yearly financial performance of Atom Bank within the Atom Bank 2025 annual report

Hello everyone,

It’s been a successful 12 months for Atom.

We delivered our plan and met the financial targets we agreed with our Board. We’ve grown both our lending and our deposits and remained unwavering in our support for the UK economy. Our total loan balances increased by 29% to £5.3 billion, a stark contrast to some of the UK’s biggest banks whose loan books, despite their dominance, have struggled to grow at more than 2% annually over the past four years. Customer numbers are up 19%, helped in part by the fact that we have offered UK savers 52% more interest on their instant access savings than the market average. Deposit balances grew by almost a third over the course of the year (31%).

We’re enormously proud to be the highest-rated UK bank on Trustpilot, as well as the UK’s highest-rated savings bank and mortgage lender, boasting a record-breaking Net Promoter Score of 89%. This isn’t luck; it’s the result of offering better value products, industry leading speed (a median residential mortgage offer in under four days), and a genuine commitment to making things as easy as possible for everyone who chooses to deal with us.

Having spent our first decade in Durham, this Autumn we will move into our new HQ building, the Pattern Shop, located in the Stephenson Quarter near the centre of Newcastle upon Tyne. The building has an extraordinary heritage. It was the design and manufacturing centre for the pioneering Stephenson brothers during the 1820s to 1850s. What was once a cradle of manufacturing and innovation for the first industrial revolution will soon become a centre of excellence for Atom as we begin the next phase of growth in our business.

We continue to invest in our people, our customers and our capabilities. Later this year we will launch our first ISA on the Atom app and in 2026 more new savings products. We have expanded our engineering and AI teams and we are also well advanced in the development of our IRB waiver application. We expect to complete the build of our second generation credit models in the autumn.

We remain one of the country’s largest 4-day week employers, a policy that remains a clear employee differentiator and one that has had a hugely positive impact on the nearly 600 people who work with us. We remain the only UK bank with a clear commitment - and investment plan - to become climate positive by 2035, covering not just our own operations but also all of the financed emissions associated with our lending.

Atom isn’t just growing; we are growing in the right way. We are working hard to build a sustainable bank that challenges the status quo, one that champions competition and serves the real economy. Last year, the majority of our income came from lending. We primarily gather deposits so that we can fuel economic growth by lending; we are not a business model dependent on placing deposits at the Bank of England to make a turn at the taxpayer’s expense. We exist to help our customers own their own homes and build their own businesses, to help them save and invest for their futures.

Let me close by thanking all of our customers for their trust and patronage, not just in the last 12 months, but since we started this journey. We are nothing without them. Thanks also to our commercial and residential mortgage brokers for their steadfast loyalty and support. I am very fortunate to be surrounded and uplifted by a fabulous team. As we say goodbye to Durham, we look forward to a new beginning in Newcastle whose motto reads: Fortiter Defendit Triumphans.

Or as we prefer to put it…Up and Atom!

The bank launched operations in April 2016 as the UK’s first app-based bank, and offers award-winning mortgages and savings through its app, alongside secured business lending for small and medium-sized enterprises.

Based in the North East of England with a team of over 550 people, Atom is here to ​​change banking for the good, for the better, and for everyone.

Based in Durham, Atom is an engaged and active member of the North East Community. In 2022 Atom signed a five-year Memorandum of Understanding with Durham University to progress key research and diversity initiatives. The region has one of the highest levels of youth unemployment in the UK and Atom is passionate about addressing the critical digital skills gap and helping develop young people and other groups that are under-represented within the industry. In 2024, Atom purchased 25 acres of newly planted broadleaf woodland in Northumberland to sequester 7000 tonnes of carbon, which will account for all its operational emissions since founding. This forms part of the bank’s pledge to be climate positive by 2035, becoming the first UK bank to make this commitment.

The Atom executive team are highly experienced, having built and run some of the most well-respected banks in the UK. CEO Mark Mullen has 30 years’ experience in the sector and was previously CEO at the multi- award-winning telephone and internet bank first direct.
