Tandem Bank has appointed Neil Chandler as its new CEO, subject to regulatory approvals. 

Chandler brings a wealth of leadership, banking and tech experience to Tandem, spending more than 30 years in senior banking, eCommerce, retailer finance and technology roles. 

He most recently served as CEO of digital bank and banking-as-a-service provider, Aion Bank, where he led Aion’s sale to UniCredit Group. 

Neil’s earlier roles included CEO of Vanquis Bank, CEO of Sainsbury’s Bank, CEO of personal loans for HBoS, and CTO for Royal and Sun Alliance.

Neil Chandler said: “Tandem's known for putting customers first. Yes, the products and tech are top notch, but importantly the bank is award-winning for its customer service. That relentless customer focus – and the bank’s dual purpose helping customers transition to a greener lifestyle while saving them money along the way – is what attracted me to Tandem. 

“Tandem’s purpose-led, inclusive approach is properly distinctive, giving consumers more affordable and accessible options to choose a greener lifestyle that makes a real tangible impact to customers’ lives – and the planet.

“I want to thank Alex for his amazing work over the past three years in creating a fantastic runway for Tandem’s next chapter. I’m excited to get going and lead this talented and passionate Tandem team.”

Tandem’s chairman, Paul Pester, commented: “Alex has done a phenomenal job reshaping the ‘new’ Tandem into one of the UK’s standout digital banks. 

“Now with Neil on board, we’re ready for the next chapter. He’s got the pedigree, the passion, and the vision to match our ambitions – with the perfect combination of experience across technology, fintech and banking. 

“We’re thrilled Neil is joining to lead our next phase of growth, securing Tandem’s status as one of the UK’s leading digital banks and furthering our mission to help many more consumers transition to a lower carbon lifestyle, while saving them money along the way.”

Alex Mollart, former CEO at Tandem, added: “We’ve built something special at Tandem – a profitable, high-growth fintech with a bold customer-focussed mission. The timing’s right for me to step down and I know Neil’s the right leader to take Tandem even further. I’m proud of what we’ve achieved, and incredibly grateful to the team that’s made it happen.”
