how many junior isas can you have
But it's different with Junior Isas. You're only allowed to have one Junior cash Isa and one Junior stocks and shares Isa. So, say you've saved Â£6,000 over the past three years in a Junior cash Isa.You've found another account that pays a better rate of interest, and want to put this year's Junior Isa allowance into it.lthough parents have to open a Junior Isa on behalf of their kids, anyone can contribute to a Junior Isa account. You can save into any mix of cash or stocks and shares, and switch between the two as often as you like. Children aged 16 and 17 can also open a cash Isa.
