I have 4 ISA accounts:

​

1. HSBC Stocks and Shares opened in 2015, contributed to last in 2015
2. HSBC Cash ISA, opened in 2015, contributed to last in 2015
3. Nutmeg Stocks and Shares ISA, opened in 2016, actively contributing to from 2016 to this tax year
4. Wealth Simple Stocks and Shares ISA, opened 2020 for transferring to

This year:

​

1. I transferred the full HSBC Stocks and Shares ISA to Nutmeg, and I am actively contributing to the Nutmeg account for this tax year
2. I transferred a part of the HSBC Cash ISA to Wealth Simple Stocks and Shares ISA, but I am not actively contributing for this tax year

Question: Is this allowed? If it isn’t, what should I do now?
