Best children’s savings account 2026

What is a children's savings account?

A children's savings account is a bank or building society account opened in a child's name, or held in trust for them, that pays interest on money set aside for their future. Unlike an adult easy access saver, many children's accounts pay a noticeably higher rate, since providers use them to build a relationship with a future adult customer. The trade-off is that most impose an age limit, a deposit cap or restrict how the account can be opened and accessed.

Broadly, three product types are available. Regular savers, such as the Halifax Kids' Monthly Saver, pay the highest headline rates in exchange for a fixed monthly deposit, typically between £10 and £100. Easy access accounts, such as HSBC MySavings or Nationwide's FlexOne Saver, allow money to be paid in and out freely at a lower, usually tiered, variable rate. Junior Individual Savings Accounts (Junior ISAs), offered by providers such as Skipton Building Society and NS&I, shelter interest from tax entirely but lock the money away until the child turns 18.

As with adult accounts, deposits are protected by the Financial Services Compensation Scheme (FSCS) up to £120,000 per person, per banking licence, for any UK-authorised bank or building society. Government-backed NS&I products sit outside this limit entirely, since they are backed in full by HM Treasury rather than the FSCS.

Junior ISA or standard children's savings account: which is right?

A Junior Cash ISA is the more tax-efficient option for larger sums or long-term saving. Interest earned inside a Junior ISA is completely free of income tax, and up to £9,000 per child can be paid in during the 2026/27 tax year, across cash and stocks and shares JISAs combined. The money is locked away until the child's 18th birthday, at which point it automatically becomes an adult ISA that only the account holder can access.

A standard children's savings account offers more flexibility. Money can usually be withdrawn for the child's benefit before they turn 18, which matters if the funds are meant for things like school trips or a first car rather than a lump sum at adulthood. Regular savers such as the Halifax Kids' Monthly Saver often pay a higher headline rate than a Junior ISA, though usually on a smaller monthly deposit limit.

A useful rule of thumb: for disciplined monthly saving of pocket money or family contributions where some flexibility before 18 is useful, a regular saver or easy access account tends to work well. For lump sums, grandparent contributions, or money you are confident will not be needed before adulthood, a Junior ISA is usually the stronger long-term choice, purely for the tax treatment.

The £100 rule: tax on money parents give their children

Most children can earn interest tax-free, since, like adults, they have a personal allowance and a starting rate for savings that in practice shelters ordinary pocket-money interest completely. However, HMRC applies a specific anti-avoidance rule to money given to a child by a parent or step-parent: if the interest generated by a parent's gifted money exceeds £100 in a tax year, the entire amount of that interest, not just the excess, is taxed as the parent's income, not the child's.

This £100 limit applies separately to each parent, so a couple can together gift enough to generate up to £200 of interest before this rule bites. It does not apply to money given by grandparents, other relatives or friends, which is taxed as the child's own income under normal rules. Keeping a simple record of who paid money into an account, and when, makes it easier to demonstrate this if HMRC ever asks.

The practical way to sidestep the £100 rule entirely is to use a Junior ISA. Because all interest inside a Junior ISA is tax-free regardless of who contributed the money, the parental gift rule simply does not apply.

Who can open and manage a children's account

Rules vary significantly by provider and by the child's age. Younger children's accounts, such as the Halifax Kids' Monthly Saver or Skipton's Junior Cash ISA, must be opened by a parent or a Registered Contact with parental responsibility, who manages the account on the child's behalf, often only in branch or by post.

Several providers introduce a degree of independence once a child reaches secondary-school age. HSBC's MySavings gives children their own debit card and mobile banking access from age 11. Nationwide's FlexOne Saver goes further, letting 11 to 17-year-olds open and manage the account entirely themselves through the app or internet bank once registered, provided they already hold a linked FlexOne current account. Santander's 123 Mini follows a similar pattern, with 13 to 17-year-olds able to apply and manage the account independently online, while under-13s need a parent or guardian to open it in trust.

Almost every children's account eventually converts into a standard adult product once the child reaches a set age, commonly 18, though Nationwide's FlexOne Saver transfers at 23 and Santander's 123 Mini converts at 19. It is worth diarising this date, since the adult product the balance lands in rarely pays as competitive a rate as the children's account did.

How to choose the right children's savings account

1. Decide between flexibility and the tax-free wrapper. If you expect to need the money before the child turns 18, avoid a Junior ISA. If you are saving a lump sum for adulthood, the tax-free treatment of a Junior ISA usually wins out.

2. Check the age range carefully. Some accounts, like Skipton's Junior Cash ISA, are open from birth. Others, like HSBC MySavings, start at age 7, and Nationwide's FlexOne Saver only from age 11. Make sure the account matches the child's current age, not just their eventual age.

3. Match the deposit pattern to how you actually save. Regular savers reward monthly discipline but cap how much can go in each month. If you are more likely to make occasional lump-sum deposits, for example from grandparents at birthdays, an easy access account or Junior ISA without a monthly cap will suit better.

4. Watch for tiered rates. Several easy access children's accounts, including HSBC MySavings and Santander's 123 Mini, pay a noticeably lower rate once the balance passes a threshold. Check where that threshold sits before assuming the headline rate applies to the whole balance.

5. Confirm the FSCS protection. Almost all providers here are protected up to £120,000 per banking licence. NS&I's Junior ISA is the exception, carrying an unlimited HM Treasury guarantee, which can matter if you are consolidating a larger family trust fund.

6. Think about who is opening it and why. If the goal is to teach a teenager to manage their own money, an account with app access and a debit card, such as Nationwide's FlexOne Saver or HSBC MySavings, has real educational value beyond the rate.

How to open a children's savings account

Opening a children's savings account normally requires proof of the child's identity, usually a birth certificate or passport, and proof of the parent or guardian's identity and address. Junior ISAs and most branch-based regular savers can only be opened in branch or by post, while some easy access accounts, including HSBC MySavings and NS&I's Junior ISA, can be opened online if the parent already holds a qualifying account with that provider.

Only one Junior ISA of each type, cash and stocks and shares, can be open for a child at any time, and only one adult, usually the person who opened the account, can act as the Registered Contact until the child turns 16, at which point the child can apply to take over that role themselves.

Common mistakes to avoid

Ignoring the £100 rule. Parents who regularly gift more than £100 worth of annual interest to a standard children's account can end up with an unexpected tax bill on their own return. A Junior ISA avoids this entirely.

Chasing the headline rate on a tiered account. A 3.75% AER heading can mask a much lower rate once the balance crosses a few thousand pounds. Check the tier thresholds against how much you actually plan to save.

Forgetting the conversion age. Money left untouched in a children's account after it converts to an adult product, sometimes automatically at 18, 19 or 23 depending on the provider, often sits in a far less competitive rate than at any point in the child's childhood.

Opening a Junior ISA and a separate regular saver without a plan. Splitting savings across account types is sensible, but only if each pot has a clear purpose. Otherwise, tracking rates and renewal dates across several accounts becomes unnecessarily complicated.

Assuming all children's accounts are protected the same way. Most are FSCS-protected up to £120,000, in line with adult accounts. NS&I's Junior ISA carries a full HM Treasury guarantee instead, which is worth knowing if a family is holding a particularly large trust fund for a child.
