Cash ISA and Fixed-rate ISA

Hi, I would like to ask the below questions to know the restriction of ISA account opening. Scenario A: If I open a fixed rate ISA in Nov 2023 and put £1,000 into it, can I open another cash ISA in Jan 2024 (within same financial year) and put £19,000 into it? Scenario B: If I open a 2-year fixed rate ISA in Nov 2023 and put £20,000 into it (using allowance in financial year 23/24), can I open another 1-year fixed and put £20,000in May 2024 (using allowance in financial year 24/25)? Thank you.

Hi 

There are 4 types of ISA, you can open one of each in the same tax year, but not more than 1 of each and deposit a combined maximum of £20000.
If you do, you will need to contact the ISA providers, to have one of the ISAs closed.  The answer to question 2 is yes, e.g. you can open a cash ISA in 23/34 and new cash ISA in 24/25.  
Have a look at the ISA guidance at Individual Savings Accounts (ISAs).

Thank you
