I have a personal, emergency fund of 7k. Completely separate to mortgage and other accessible emergency savings for vet bills and the like, just for an unlikely, worst-case scenario such as splitting up and needing funds to find a new place etc. I'd like it to be accessible if need be in dire straits (even if there's a penalty to access it) but don't forsee that I will ever need to use it, so I'd like it to be gaining some decent interest for the next X amount of years so I can have a nice payoff in two to three decades. It's currently in a basic building society ISA, but are there any other places I could put it, such as a stocks and shares ISA? (never done anything with any 'risk' before). Thanks!
