What is a Cash ISA?

A Cash ISA (Individual Savings Account) is similar to a regular savings account, but you earn tax-free interest on your savings.
-
How many Cash ISAs can you have?
-
As long as you don't exceed the annual contribution limit, you can technically have as many Cash ISAs as you like. You can have Cash ISAs with different providers, although some will only let you have one Cash ISA with them.
