Is anything taxable?

I’ve setup a cash ISA with trading 212 which I paid £20k into last year and topped up again this year with another £20k.

Following months of research I’ve dipped my toe into investing and bought £1000 of VWRP this morning (which I intend to leave for at least 10 years and top up yearly).

Finally my current account pays interest on the cash I have in that but I’ll be moving most of that into 212 when I am able to.

Is any of the above taxable and if so how do I go about declaring?
