Who they are
CMC Invest traces its roots to 1989, when Peter Cruddas founded the business under the name Currency Management Corporation, later shortened to CMC and then rebranded as CMC Markets in 2005.
CMC Invest itself is the company's UK investment platform, launched in 2022. The parent, CMC Markets Plc, is listed on the London Stock Exchange and is one of the UK's oldest CFD and foreign exchange trading service providers. That heritage gives it a more established compliance and regulatory footing than many newer app-based rivals.
For savers rather than traders, CMC Invest is primarily a cash ISA provider sitting alongside its broader investing platform. Its entry-level plan covers a flexible Cash ISA, Junior Cash ISA and general investment account, with no monthly fee.
Savings accounts
CMC Invest currently offers two cash savings products. The Easy Access Cash ISA pays 3.69% AER (variable) and can be opened from just £1, with instant access to your money. The Junior Cash ISA pays 3.56% AER (variable), also available from £1, with funds locked until the child turns 18 - as is standard with all Junior ISAs. Both rates are variable, so they can change at any time.

There are no fixed-term or notice accounts listed at present, so if you need those, you will want to compare elsewhere.
Is it right for you?
CMC Invest suits savers who want a tax-free home for their cash and may also be interested in branching into investing further down the line - the Premium plan lets you manage an ISA, general investment account and SIPP all in one app. The Junior Cash ISA is a tidy option for parents wanting to give children a financial head start.
If you just want a straightforward cash ISA with no monthly fee and instant access, the entry-level plan covers that without any subscription cost. There are no current-account switch offers to factor in.
