Yes you can. It is entirely up to you how much of your ISA allowance is invested in each of the different types of ISAs.

There are five types of ISA: Cash, Stocks and Share, Lifetime, Help to Buy and Innovative Finance ISAs.  

You are only permitted either one Lifetime or Help to Buy if you qualify and then one ISA of each type per tax year. 

For example, you could split your allowance across one Cash ISA, one Stocks and Shares ISA and one Innovative Finance ISA.

Good to know

Minimum and maximum investment amounts vary with each ISA provider so be sure to check before making any commitments. 

Please remember that the maximum allowance is £20,000 no matter which ISA or combination of ISAs you choose in the current tax year.
