Consolidating cash ISAs

Red_Admiral_22

Must consolidated cash ISAs never exceed a combined total of £20K, or can I consolidate two or more £20K ISAs, perhaps including a new one for the current 24/25 year?

20k is the annual subscription limit. That's it. Nothing else is tied to that number unless a particular product says so.

If each individual ISA could only be 20k, where would the interest go?

Thank you gravel_2, that's very helpful
