Help your children build up a pot of money for the future and teach them about the importance of saving.

Why choose Family Building Society?

We're an award-winning building society that does things differently, with over 125 years supporting savers and over 52,000 account holders. No matter what you're saving for we're here to help and have a chat if you like, with minimum jargon.

 

Junior Cash ISA (3) – you will need to be someone who has ‘parental responsibility’ of the child to open a Junior Cash ISA on their behalf, so any grandparent(s) would need to be the legal guardian of the child. Grandparents can still pay into their grandchild’s Junior Cash ISA, even if they are not the legal guardian.

Junior Saver (2) – Yes, grandparents are able to open this account as a trustee on behalf of a child of any age. Trustees must be close family members such as parents, adult siblings, parent’s siblings (aunts or uncles) or grandparents.

Yes you can. You can open an account for both our Junior Cash ISA (3) and Junior Saver (2) from birth up to age 18.

The main difference between the two accounts is that the Junior Cash ISA is a tax-free savings account and is used as a longer-term saving option. Each year, you can save from £1 up to the annual statutory Junior Cash ISA limit. No withdrawals are allowed, and the account cannot be closed until the child reaches 18 (although transfer to another Junior Cash ISA provider is allowed, after a 45 day notice period or subject to the loss of 45 days’ interest on the total amount transferred).

The Junior Saver is an easy access account, with a maximum balance of £25,000. Up to 12 withdrawals can be made without notice or access charge per year. This account is not tax-free.

Depending on how much access you would like to your children’s savings account will determine the type of account you choose.

Your savings are in safe hands, protected up to a total of £120,000 by the Financial Services Compensation Scheme. This limit is applied to the total of any deposits you have with the following: Family Building Society and National Counties Building Society. Any total deposits you hold above the limit between these brands are unlikely to be covered.

You can apply for our Junior Saver (2) or Junior Cash ISA (3) account by post or at our Epsom branch.
