How do I open a Junior ISA?

A Junior ISA is a great way of saving money for a child's future, and with us it's easy to do

You can now save up to £9,000 each year into a Junior ISA for someone under 18, and any growth on the investment or interest on the savings are free from tax. It's a way to save or invest for a child in a tax-efficient way.

Our Junior ISA invests in stocks and shares, which means the money can benefit from more growth than cash over the medium or long term. As with any investment, there is a risk the value of the investments can go down as well as up.
