Rules around holding two S&S ISAs

Lee_N

I'm struggling to find an answer to what we can and cannot do with two (or more) ISAs of the same kind. I understand we can only add max 20k contributions to an ISA (or split between ISA types) per tax year. For my question, here's a hypothetical:

S&S ISA - HL
I've already added money and investments to this ISA, this current tax year.

S&S ISA - iWeb
6th April this year I decide to open another S&S ISA with iWeb, add money and buy funds etc. I will keep the HL one open but don't add any new money for the rest of this same tax year (I get that). 

Where I'm unsure is what I will then be able to do with HL ISA . Am I right in thinking that I can continue doing all of the following during the tax year starting 6th April.

Sell funds / shares
Buy funds / shares
Hold cash
Withdraw cash

Basically, I can do anything I want with it as long as I don't add any "new" money while I'm contributing to another S&S ISA for the tax year?

Question 2:
What actually counts as an ISA for the tax year? Not sure that question makes sense so here's another example.
From 6th April this year I start using iWeb S&S ISA - but I also want to add money to a cash ISA for the same tax year. Must I use a cash ISA held with iWeb as they will be holding the current year's S&S ISA ... or could I use the HL cash ISA and the iWeb S&S ISA for the same year?

Hope that makes sense.
Thanks in advance.

Yes.

You can pay into a cash ISA with one provider while concurrently paying into a S&S ISA with another one (but just to be clear, HL don't offer a cash ISA).

Great, thank you.  

I doubt I'd bother with a cash ISA either way but having nearly opened two S&S ISAs this year by mistake (newbie) I'm trying to familiarise myself with as many rules as I can, the .gov guidelines can be a bit vague on specifics like this.

Thanks again.
