Anyone can top up a child’s Junior ISA up to the annual allowance of £9,000 (for the 2025/2026 tax year). This can be done in minutes by debit card as a lump sum or monthly direct debit from £25 per month. An HL Junior ISA account will need to be opened by the parent or legal guardian before you can top up.

  • Investments can go up and down in value so the child could get back less than you put in.

  • Tax rules for Junior ISAs can change, and their benefits depend on yours and your child's circumstances.

  • Once money is in the HL Junior ISA, the money can’t usually be taken out until the child’s 18th birthday.

  • An HL Junior ISA is for people comfortable choosing their own investments. If you’re not sure which investments are right for you, please ask us about financial advice. There’s no personal advice on our website.

Before you invest, please make sure you’ve read and understood our: terms and conditions (including tariff of charges), key features and the risks. Please contact us if you have any questions.
