Fintech lender Tandem has officially completed its acquisition of Harrods Bank, a move that grants the London-based lender a banking license, it announced yesterday.

A mobile-based lender that allows customers to aggregate all of their financial information in one place to help users save and budget, Tandem lost its banking license in 2017 after an investment from House of Fraser fell through.

The acquisition, first announced in August, also doubles the London-based fintech’s customer base, expanding it to about 21,000 customers.

Additionally, the closure of the acquisition brings Harrods’ more than £400 million (about $545 million) deposit business and £375 million mortgage book (about $511 million) to Tandem’s door.
