Read the important information below
Whether transfering your Junior ISA in branch or by post, please click on the links below to read the important information before making a transfer:
A Junior ISA, otherwise known as a Junior Cash ISA or simply JISA, is a long-term, tax-efficient way to save or invest for a child under the age of 18.
This type of savings account allows parents or guardians to save up to £9,000 each tax year (2025/26) for their child, without having pay tax on the interest or investment returns earned.
When you open a Junior Cash ISA, the money you deposit is locked away until the child turns 18. Once they reach 18, the Junior ISA automatically converts into an adult ISA, and the money becomes theirs to manage.
A key benefit of a Junior Cash ISA is its tax efficiency. Any interest earned is free from Income Tax, so neither you nor your child will pay tax on their savings. While parents and guardians can contribute, the total amount paid across all Junior ISAs for a child cannot exceed the annual JISA allowance of £9,000 each tax year (2025/26).
Our Junior ISA is FSCS protected and has a variable rate of interest that can go up or down. With a deposit of just £1, you can open a JISA with us and start saving for your child's future.
As a mutual building society with a proud heritage, we recognise how savings accounts play a vital role in building the future you want for you and your loved ones. For over 160 years, we’ve put our members first, providing them with real value that goes beyond competitive rates.
