WhichBrokr Category Ratings
Overview
Monzo was founded in 2015 and received its full UK banking licence in 2017 — one of the first UK challenger banks to achieve this. It now serves 10 million UK customers and consistently achieves the highest customer satisfaction ratings of any UK bank in surveys by Which?, Trustpilot and the CMA banking service quality metrics.
Monzo's core strength is its app experience: real-time transaction notifications, merchant-level categorisation, Pots (separate savings ringfences), bill splitting, round-up saving, and shared tab management. These features are now commonplace in challenger banking but Monzo pioneered most of them.
Monzo expanded into investments via Monzo Investments (FCA regulated, launched 2024) — offering BlackRock funds and ETFs. Fees (0.59%–0.79%) are above dedicated brokers but integrate seamlessly for existing Monzo users. For active ISA investors, a separate Stocks & Shares ISA (Freetrade, Trading 212) remains lower-cost.

Verdict
WhichBrokr's Take
Monzo is the best UK neobank for everyday personal banking. Full PRA/FCA banking licence, £85,000 FSCS protection, 10 million customers, and a 4.9★ rated app that consistently outperforms every traditional bank create a compelling case for your main current account.
For investment needs (ISA, stocks), Monzo Investments is convenient but charges 0.59%–0.79% annually — meaningfully above Freetrade or Trading 212. Most serious ISA investors should use Monzo for banking and a dedicated low-cost broker for investments.
Best for: UK residents wanting the best banking app with full FSCS protection. Families and flatshares using bill splitting. Everyday banking replacing a traditional bank. Not ideal for: Investment-focused users (use Freetrade/Trading 212 for ISA), international travellers needing free global ATMs (use Revolut), or those wanting a SIPP or LISA.
