Our Expert Opinion on CMC Invest Easy Access Cash ISA

Jonny PeaseCo-Founder, DepositScout

At 3.69%, this Cash ISA sits below the market average and 1.43% behind the best Cash ISA rate available at 5.12%, so it is hard to recommend on rate alone. It does beat CPI inflation of 3.1% by 0.59%, which at least preserves real value. The flexible ISA structure with unlimited withdrawals is genuinely useful, and the £1 minimum and £20,000 cap make it accessible, but the money is held via Qualifying Money Market Funds rather than a traditional deposit, which is worth understanding before opening. Those who want a straightforward easy-access ISA with better rates could look at Tembo's Standard Cash ISA at 4.00%.
