Complaints Data

01/04/2025 to 30/09/2025

Here at Atom bank, we try to put our customers at the heart of everything we do, but that doesn’t mean we get things right every time. On occasion, we might make a mistake that leads to a complaint being submitted. We take these very seriously, so we try our best to rectify the situation and use the lessons learned to make our bank better.

Below, you can find a breakdown of the complaints we’ve received over the past six months, including the number we’ve received and how quickly we dealt with them. We submit this data to the Financial Conduct Authority (FCA), which regulates us as a bank.
