The three contenders at a glance
Chase UK launched in September 2021 as JPMorgan's consumer banking brand in Britain. It received its full UK banking licence in March 2026 — five years after applying. Despite the regulatory delay, it's grown aggressively on the back of headline-grabbing savings rates and 1% cashback.
Monzo has been a UK banking licence holder since 2017. The hot-coral card and real-time spending notifications defined the challenger bank category. It now serves over 9 million UK customers and turned its first annual profit in 2024.
Starling launched in 2014 under Anne Boden, won a £100 million prize from the Capability and Innovation Fund, and built a profitable business anchored in small business banking. It has over 4 million accounts.
All three are app-only banks with no physical branches. All are regulated by the FCA and PRA. All are covered by the FSCS £85,000 deposit protection. Beyond those basics, they diverge sharply.
