Income from bank saving interest - ISA account and non-ISA account

Hi I have saving in UK in ISA and non-ISA account, when I do the self assessment for my income, do I need to input all interest from both accounts or I just need to report the interest from non-ISA account? (as I know the interest in ISA will be within GBP1000 tax free allowance but not sure if bank will directly report to HMRC or I need to report everything then HMRC will do tax assessment as a whole?), thanks!

Hi
You only need to declare the non-ISA interest.
