When it comes to bank accounts for kids, it’s never too early to start saving for your child’s future – the sooner you put money away the more time there is for it to earn interest and build up. And with children likely to need all kinds of things when they get older, from money for university to a deposit for a property, they need all the financial help they can get.

Although you can save for your children in your own accounts, which means you’ll always have control of the money, there are a number of benefits to taking out dedicated children’s ones. 

Interest rates are often higher than for adult accounts, you can benefit from the tax-free allowance you get with Junior Isas and you can keep the money separate and often locked up so you’re not tempted to spend it. You also won’t use up your own tax-free allowances.

As a parent or guardian you’ll usually manage your child’s account on their behalf if they’re under a certain age, which means you can take money out for them if the account lets you make withdrawals, but anyone can pay money into it if they want to contribute.

You broadly have two strategies open to you – either you lock your child’s money away until they’re 18, when they’ll get a nice nest egg, or you take out an account that gives your child more control over their savings so they can save up for specific things and learn to manage their finances themselves. You may decide to use a combination of both.

The main types of accounts you can save into for children are junior ISAs, easy-access accounts, or fixed rate. We explain what they are below and the best ones available right now.

Best instant access children’s savings accounts 

These either let you take the money out whenever you like or after a notice period, such as 100 days. Your child can manage the account themselves when they get to a certain age. The higher-paying accounts often pay lower or no interest above a certain balance though.

This account is for children aged seven or older. They can withdraw money using their cash book but if they’re under 11 they’ll need your permission if it’s more than £50.

  • Minimum opening balance £0
  • Instant access
  • Interest paid monthly
  • Maximum age 17

This account is technically a current account but pays a great interest rate of 3% once the balance reaches £1,500. It’s 1% below £1,000 and 2% from £1,000 to £1,499.99. Nothing is paid above £2,000. You can hand the account over to your child to manage when they’re 11. Once they manage it themselves they can get a cash or debit card. It can be operated online, in branch and via telephone and mobile banking. 

Best Junior cash ISAs 

These are long-term savings accounts that currently let you save tax-free - you can save up to £9,000 a per tax-year. Although children don’t usually have to pay tax on savings interest, if they earn more than £100 a year from money given to them by a parent or guardian, then you may have to pay tax on it. This doesn’t apply to money in a Junior Isa.

A parent or guardian can open a Junior ISA - but beware, once it is opened, only the child can access the money when they are 18. They can manage the account themselves when they’re 16 but can’t take the money out until they’re 18.

As with adult ISAs, Junior ISAs can either be cash or stocks and shares ISAs and your child can hold one or both types. Returns can be higher with a stocks and shares ISA but their value can go down as well as up.

Here, we have listed the best cash Junior ISAs.

  • Interest rate 2.6% AER (variable)
  • Minimum opening balance £1
  • No withdrawals until age 18
  • Interest paid yearly
  • Maximum age 17

You can apply for and operate this account by post or telephone. You can also pay cash and cheques in at a Coventry BS branch.

  • Minimum opening balance £100, maximum balance £500,000
  • No withdrawals until age 18
  • Interest paid yearly
  • Maximum age 17

This account only comes second to the Coventry BS account above once the balance reaches £2,500, when the rate jumps from 1.45% to 2.55%. As with all Junior Isas, you have to open the account on behalf of your child if they are under 16. You can only open and operate it in a branch or by post but can also use email and phone to ask questions about your account. Transfers in from other ISAs are allowed.

Account selection based on data from on 17 June 2022. AER means annual equivalent rate and is the interest you would earn over a year. You should use this to compare accounts.
