Tandem launched in 2014 as one of the UK's original digital challenger banks providing customers with simple, transparent and fair products across its range of savings and mortgages. Tandem acquired Harrods Bank in 2018 and Allium Lending Group in 2020, a business focused on the home improvement lending sector.
Oplo launched in 2009, developing into a strong, profitable consumer lending business focusing on the new mainstream of UK borrowers underserved by traditional High Street banks. In little over a decade Oplo has provided £915 million loans to customers since launch.
In 2022 Oplo merged with Tandem Bank to create a fairer, greener digital bank.
