Hi,
Every tax year you can put money into one of each kind of ISA. The tax year runs from 6 April to 5 April. You can save up to £20,000 in one type of account or split the allowance across some or all of the other types.
Individual Savings Accounts (ISAs)
If you have more than 1 ISA of the same type, you can only deposit in one of them, up to a maximum of £20000.
Thank you.
