Chandler’s appointment is subject to regulatory approval, and he brings over 30 years of experience in senior banking, e-commerce, retailer finance and technology roles.
He has been chief executive of digital lender Aion Bank since 2023, and oversaw its sale to UniCredit Group, which was one of the biggest European fintech exits this year.
Chandler has held chief executive roles at Vanquis Bank and Sainsbury’s Bank, and has also worked at Apax, Shop Direct and HBOS.
Chandler (pictured) 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.”

“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.”
