Coordinate before sending a gift
Ask the parent or guardian whether an account already exists. For a young child, a grandparent generally contributes to a Junior ISA opened by someone with parental responsibility. Check the provider’s payment instructions rather than assuming any bank transfer will be accepted.
Agree the practical details
Confirm the account reference, how a payment will be recognised, whether a standing order is possible and who will track the annual total. Keep a receipt. Avoid putting the child’s account details or identifying information into a family group that is wider than necessary.
Remember whose money it becomes
A contribution into a child-owned account is a gift to the child. Discuss access and control with the parent first, particularly if you have a specific use in mind. A Junior ISA and a pension involve very different timescales.
Keep tax questions separate
Ordinary children’s savings have rules that differ from Junior ISAs. GOV.UK says the special £100 interest rule for money given by a parent does not apply to money given by grandparents, other relatives or friends. That does not mean every gift is free of all tax considerations: large gifts and inheritance planning deserve individual advice.
Make the gift understandable
A short note about why you are contributing can make an invisible account feel meaningful. You might pair a gift with a conversation about saving towards something, without promising a future balance. There is no need to disclose account credentials or ask a child to monitor markets.
