Shares Account Interest on Residual Cash

I have a stocks and shares account that is neither an ISA or SIPP and therefore subject to capital gains on profit over the £3,000 allowance for the 2024/25 tax year. Within the account I also get interest on any residual cash that has not been invested on a daily basis. I fill out a self assessment form and my question is does the interest also count as capital gains or as bank account interest as the trading app I used is affiliated with JP Morgan?

Hi,

It will just be the interest.

Thank you.
