How to choose an ISA

If you have some money to put into savings or investments, then an ISA is your best friend. You can currently put up to £10,200 a year into an ISA - or £5,100 if you want to keep your savings in cash - and any returns are paid tax-free.

You can even split your money between the two, sheltering £5,100 from tax in a cash ISA and a further £5,100 in a stocks and shares ISA. But how do you decide which ISA to go for?
