David McCarthy has been appointed as Tandem’s Chief Financial Officer (CFO) becoming a member of both the bank’s Board and executive committee. David joins Tandem from Atom Bank where he has been CFO for the past eight years, following previous CFO and senior finance roles at Britannia Building Society, Co-Op Bank and Bank of Ireland.

Wahid Ali is joining Tandem as Chief Risk Officer (CRO) from specialist lender Masthaven and will join David as a member of Tandem’s executive committee. Wahid has 20 years' risk management experience from across the banking sector including holding senior positions at Barclays, RBS and Al Rayan Bank, as well as the Prudential Regulatory Authority (PRA).

The arrival of both senior executives underlines the continued momentum and growth of Tandem as one of the UK’s original digital challenger banks.

Tandem announced the appointment of industry stalwart Paul Pester as Chairman in June, and has recently confirmed that Deputy CEO Alex Mollart will shortly step up to become CEO.

Alex Mollart, Tandem Bank’s Deputy CEO, said:

“I’m thrilled to have both David and Wahid on board for the next stage of Tandem’s journey to becoming the UK’s greener, digital bank.

“There’s no question David and Wahid bring a wealth of knowledge, expertise and experience to the Tandem team as we continue to grow and become the go-to option for customers transitioning to a lower-carbon lifestyle.”

Drawing on Tandem’s digital credentials and strong customer proposition, the bank is positioning itself to be the go-to green bank, helping customers to access finance and practical advice that will help them transition to a lower cost and lower-carbon lifestyle; from retrofitting their homes and reducing their emissions with electric vehicles, to saving money on energy with solar panels and other low carbon technologies.

Tandem recently launched a specialist green mortgage and created its ‘Tandem Marketplace’, a hub for consumers to find sustainable and energy efficient products and services.
