Our verdict

CMC Invest’s flexible Cash ISA pays 3.69% AER (variable) with tax-free interest calculated daily and paid monthly, offering unlimited withdrawals without reducing the rate and a £1 minimum deposit to get started.

Is the CMC Invest Cash ISA any good?

Yes, we rate CMC Invest's 3.69% Flexible Cash ISA as excellent as it comes with unlimited withdrawals and no fees.

Customers can easily transfer existing ISAs in-app, benefit from FCA regulation and protection of client money, and access the account within CMC’s wider investing platform, which serves over 1.5 million global users. The ISA is fee-free to hold (with an optional £15 urgent withdrawal fee) and sits alongside CMC Invest’s subscription plans that add investing features, lower FX fees and broader market access for those using the wider platform.
