UK best banks 2025: Monzo and Starling tie, Chase leads rates

Monzo and Starling are jointly ranked as the UK’s best digital‑first banks in 2025, while Chase UK tops the list for current‑account interest rates at roughly 2.5% AER, a figure that puts it ahead of most rivals and could steer savers toward higher‑yield products【2】.

Digital‑bank leadership

DataGardener’s analysis of CMA and Which? surveys shows Monzo and Starling each claim the #1 spot for digital‑first banking in the UK, but they excel in different areas. Monzo’s strength lies in its simple, instant‑notification interface and fee‑free international spending, earning it the top rank in the CMA survey【2】. Starling, meanwhile, retains its Which? Recommended Provider status for a seventh straight year, underscoring consistent service quality and strong business‑banking integration【2】. Both banks serve large customer bases—Monzo alone exceeds 12 million users—highlighting the scale of digital banking adoption in the UK【2】.

Chase’s rate advantage

Chase UK distinguishes itself on the savings side, offering a current‑account interest rate of about 2.5% AER for the first six months after account opening, which sits roughly 1.25% below the Bank of England’s base rate【2】. The product also includes a 1% cashback on everyday spending for the first year, adding a tangible reward element that many traditional high‑street accounts lack. Finder’s 2025 awards gave Chase a perfect “would recommend” score, reinforcing its appeal to rate‑sensitive consumers【2】.

What to watch

• Upcoming CMA consumer‑banking survey release (expected Q3 2025) – could confirm or shift the digital‑bank rankings.
• Bank of England base‑rate decisions in the next monetary‑policy meeting – will affect the relative attractiveness of Chase’s 2.5% AER.
• Any changes to Which? Recommended Provider status for Starling – would signal shifts in service quality perception.

The tie between Monzo and Starling signals that digital convenience and reliable service are both critical to UK consumers, while Chase’s aggressive rate offering may pressure rivals to boost their own savings products. The evolving landscape will hinge on regulatory surveys and monetary‑policy moves that could reshape the competitive balance.
