Our Expert Opinion on Monzo Select Access Cash ISA

Jonny PeaseCo-Founder, DepositScout

The headline 3.65% only applies if you hold a paid Monzo plan (Perks costs £9 a month or more) and make no more than two withdrawals in a year; free account holders are capped at 3.15%, dropping to 2.60% if you dip in more than twice. Even at best, this is 1.47% below the Cash ISA market leader at 5.12%, putting it below the market average. Transfers in are not accepted either, so I would look at Tembo's Standard Cash ISA at 4.00% before committing here.
