Customers will be given personal notification of any material reduction in interest rates a minimum of 14 days before the change takes effect.

To understand why rates may be reduced please refer to our Savings Terms and Conditions.
What would the estimated balance be after 12 months based on a £1,000 deposit? £1,003 (based on the assumption that no further deposits or withdrawals are made during the 12 months).
How do I open and manage my account?
  • The account can be opened for a child who is under 18 years old on a signatory or trustee basis. However, if the child is aged between 14 years and 17 years old, they can open it on their own.
  • For accounts opened on a signatory basis, the child will always be the named account holder.
  • For accounts opened on a trustee basis, the trustee will always be the named account holder.
  • The signatory, trustee and child must be a UK resident for tax purposes.
  • Open in branch, agency, or by post.
  • Minimum balance is £1, maximum investment is £25,000.
  • When the child reaches 18 years old the account will mature and the balance will be transferred to our Instant Access Account or its nearest equivalent available.
  • Manage in branch, agency, or by post.
Can I withdraw money?
  • Yes, you do not have to give notice to close your account or make a withdrawal.
  • If the account is closed or a withdrawal is made on the child’s behalf, this must be for the child’s benefit.
  • If the child is under 14, only the signatory or trustee can make withdrawals.
  • From the child’s 14th birthday onwards, the person or people managing the account can decide to pass control of the account to the child. After this, only the child can make withdrawals.
Additional information
  • For accounts opened on a trustee basis: after the child’s 18th birthday, if the beneficiary requests that the funds are transferred to them, then the trustee is obliged to do so.
  • Service charges and costs may apply to your account. These are outlined in our Tariff of Charges.
  • If the total amount of interest you earn exceeds your Personal Savings Allowance then you may have to pay tax directly to HMRC. For more information visit
