The Competition and Markets Authority (CMA) has published its 14th annual banking satisfaction survey, revealing that challenger banks continue to lead in customer satisfaction ratings. Monzo has been ranked as the top bank for both personal and business current accounts in Great Britain and Northern Ireland, outperforming traditional banks.

This survey, conducted by independent research firms Ipsos and BVA-BDRC, assesses the service quality of personal and business current account providers. It evaluates various banking services, including online and mobile banking, overdrafts, and in-store experiences. For small businesses, the survey also considers the effectiveness of account managers.

A notable new entrant in this year's survey is Mettle, an online business current account provider from NatWest, catering to sole traders and small companies. The survey results for the period from July 2024 to June 2025 are now available, showcasing the performance of various banks.

In Great Britain, Monzo topped the personal current account rankings, followed by Chase and Starling Bank. Traditional banks like The Co-operative Bank, Virgin Money, and Royal Bank of Scotland ranked significantly lower. For business accounts, Monzo again led, with Mettle and Starling Bank following. Traditional banks like Barclays and HSBC UK shared lower rankings.

In Northern Ireland, Monzo also ranked first for personal accounts, with Nationwide and Starling Bank following. For business accounts, Santander took the top spot, with Danske Bank and Ulster Bank sharing the second position. The Co-operative Bank and Allied Irish Banks ranked at the bottom.

Daniel Turnbull, Senior Director of Markets at the CMA, emphasized that the survey empowers customers to make informed decisions about their banking options. The CMA mandates that banks display these results prominently, encouraging transparency and competition in the banking sector.
