Tandem Bank, a UK-based digital challenger bank focused on sustainable finance, has appointed Neil Chandler, former CEO of Aion Bank, as its new chief executive officer.
Chandler will take over the role from outgoing CEO Alex Mollart on 30 June, pending regulatory approval, as Mollart prepares to retire following more than 30 years in the financial services sector.
Founded in 2014, Tandem positions itself as “the UK’s greener, digital bank,” offering environmentally focused financial products.
With a workforce of around 500 people across four sites in the UK, the bank reported a 40% year-on-year profit increase last year and currently holds over £1.5bn in assets under management.
Tandem provides a suite of savings accounts and lending services, including motor finance and mortgages. Its mission is to support customers in “transitioning to a lower carbon lifestyle” through more sustainable banking options.
Chandler joins Tandem with a career spanning over three decades across banking, e-commerce, retailer finance, and technology. Most recently, he was CEO of Belgium-based Aion Bank, a digital bank and Banking-as-a-Service (BaaS) provider. He played a pivotal role in the sale of Aion and its BaaS partner Vodeno to UniCredit for €370m in July 2024.
His previous roles include CEO positions at Vanquis Bank, Shop Direct, and Sainsbury’s Bank, reinforcing his track record in leading financial institutions through transformation and growth.
Alex Mollart, who stepped into the CEO role three years ago following Susie Aliker’s departure, is retiring from full-time employment after a long and varied career in financial services.
Tandem Bank CEO Neil Chandler said, “Tandem is a fantastic business and one of the true pioneers of greener digital banking in the UK. I’m looking forward to working with the team to continue to grow the business and help customers take control of their finances in a way that is better for the planet.”
Tandem Bank outgoing CEO Alex Mollart said, “It’s been a huge privilege to lead Tandem through its recent transformation and growth, and I wish Neil and the team continued success.”
