How much you can save
The Junior ISA limit is £9,000 for the current tax year, separate from any adult ISA allowance. Anyone can contribute, not only a parent, and money can go into a cash Junior ISA, a Stocks and Shares Junior ISA, or split between one of each, as long as the combined total stays within £9,000.
Because anyone can add money once the account is open, some families use it as a place for grandparents, other relatives or friends to contribute too, for birthdays or other occasions, rather than each buying separate savings products. Only the parent or guardian who opened the account, or the child once they reach 16, can manage it or choose the provider. A relative who contributes money does not get any say over how the account is run.
Who controls the account, and when
A parent or legal guardian opens and manages the account while the child is young. From age 16, the child can take over managing it themselves, including choosing the provider, though they still cannot withdraw any money at that point. Access only opens up at 18, when the account automatically converts to a normal adult ISA and the child gets full control of the money, with no say for the parent who set it up.
Cash or Stocks and Shares Junior ISA
A cash Junior ISA pays interest and cannot fall in value, which suits money you want to be certain is there at 18. A Stocks and Shares Junior ISA invests the money instead, which has historically grown more over long periods but can also fall in value along the way. Because a Junior ISA often runs for many years before the child can access it, some parents use the time horizon to accept more short-term ups and down in exchange for the chance of higher long-term growth, though that is a judgement for each family to make, not a guarantee either way.
Is the money taxed?
No. All interest, dividends and growth inside a Junior ISA are entirely free of Income Tax and Capital Gains Tax, for the child and the parent alike. This matters because of a separate rule for ordinary children's savings accounts outside an ISA: interest is taxed as the parent's own income once it goes over £100 a year per parent, per child, if the money came from that parent. A Junior ISA is not affected by that £100 rule at all, whoever contributes. That is one reason many parents prefer it once contributions are more than pocket money.
Choosing a provider
Not every bank or platform offers a Junior ISA, and the ones that do vary in what they support. The tables on this page show whether the cash version is flexible, whether transfers in are accepted, and which investment range a Stocks and Shares provider offers. Because the account is likely to run for many years, it is worth checking a provider's transfer process too, in case you want to move it, or hand it to the child to manage from 16, without it being awkward to move later.
Moving a Child Trust Fund
A child cannot hold a Junior ISA and a Child Trust Fund at the same time, so an existing Child Trust Fund normally needs transferring into a Junior ISA first, or the Child Trust Fund provider needs to convert it directly. Ask the Junior ISA provider you want to move to about handling the transfer, in the same way you would transfer an adult ISA between providers, rather than withdrawing the Child Trust Fund yourself.
What happens at 18
On the child's 18th birthday, the Junior ISA becomes an adult ISA automatically, and the money, along with any further contributions, becomes entirely theirs to spend, save or invest as they choose. There is no option for a parent to delay or restrict this once the child reaches 18.

Questions people ask
Who can open a Junior ISA?
Any UK resident child under 18 can have a Junior ISA, opened by a parent or legal guardian if the child is under 16. A child cannot hold a Junior ISA and a Child Trust Fund at the same time, so an existing Child Trust Fund normally needs transferring in first.
How much can go into a Junior ISA each year?
Up to £9,000 in the current tax year, from any combination of family and friends. This limit is separate from the adult ISA allowance and does not use up anything from a parent's own £20,000 allowance.
Who controls the money?
The child can manage the account themselves from age 16, choosing the provider and how it is invested, but cannot withdraw any money until they turn 18. At that point the account automatically becomes a normal adult ISA and the money is entirely theirs.
Can a child have both a cash and a Stocks and Shares Junior ISA?
Yes, a child can hold one cash Junior ISA and one Stocks and Shares Junior ISA at the same time, as long as total payments across both stay within the £9,000 annual limit.
Is money in a Junior ISA protected?
Cash held with an authorised UK bank, building society or credit union is protected by the Financial Services Compensation Scheme up to £120,000 per person, per banking licence. Investments held through an FCA-authorised platform are covered up to £85,000 per person, per firm if the platform itself fails.
Can grandparents or other family pay into a Junior ISA?
Yes. Anyone can contribute to a Junior ISA once it is open, not only the parent or guardian who set it up, as long as the total paid in across everyone stays within the annual limit.
