An estimated 750,000 UK Child Trust Funds (CTFs) remain unclaimed as of April 2026. These accounts collectively hold between £1.5 billion and £1.6 billion, with the average balance in each unclaimed CTF being approximately £2,200. This substantial sum represents tax-free savings intended for individuals born in the UK between 1 September 2002 and 2 January 2011. A significant contributing factor to this situation is that 61% of these unclaimed CTFs were allocated by HMRC, meaning many families may have never been aware of their existence. This analysis details who is eligible for a Child Trust Fund, the methods for locating a lost account, and the precise steps required to access these funds, potentially resulting in an individual claiming around £2,200.

Understanding Child Trust Funds: Eligibility and Purpose

Child Trust Funds were a government initiative designed to ensure that children born within a specific timeframe would have a savings vehicle as they entered adulthood. Eligibility for a CTF was restricted to children born in the UK between 1 September 2002 and 2 January 2011. For each eligible child, either parents or guardians could open an account, or if no account was opened by the parents within the specified deadline, HMRC automatically established one on the child's behalf. This dual mechanism for account creation means that some accounts were actively managed by families from the outset, while others existed without the immediate knowledge of the child or their guardians.

A key feature of Child Trust Funds is their tax efficiency. All savings paid into a CTF are entirely free from both income tax and capital gains tax. This tax-free status was designed to encourage long-term saving and to provide a financial benefit upon the child reaching adulthood. The funds within a CTF become accessible to the child when they turn 18. Before this, from the age of 16, the child gains the ability to manage the CTF independently. Prior to the child reaching 16 years of age, the parent or guardian held responsibility for managing the account.

The Unclaimed Challenge: Why Accounts Are Lost

The significant number of unclaimed Child Trust Funds, estimated at 750,000 as of April 2026, highlights a substantial challenge in connecting individuals with their rightful savings. A critical insight from analysis by the Share Foundation indicates that 61% of these unclaimed CTFs were originally HMRC-allocated. This statistic points to a primary reason for accounts remaining unclaimed: the initial lack of awareness among families.

When parents or guardians did not open a Child Trust Fund within the allocated timeframe, HMRC automatically established an account for the child. While this ensured that every eligible child received a fund, it also meant that for a majority of currently unclaimed accounts, the family might not have received direct communications or might have misplaced initial documentation. Over time, as children grow and families move, the details of these HMRC-allocated funds can become obscure or entirely forgotten. This situation results in approximately £1.5 billion to £1.6 billion sitting in accounts awaiting claim, with an average individual balance of around £2,200.

Official Retrieval: Utilising the HMRC Online Tool

For individuals seeking to locate a lost Child Trust Fund, the official and primary route is through the free online tool provided by HMRC. This tool is accessible at gov.uk/child-trust-funds/find-a-child-trust-fund. The process is designed to be straightforward, guiding claimants through the necessary steps to identify which provider holds their CTF account.

Eligibility and Access Requirements

To use the HMRC online tool, specific eligibility criteria must be met. The user must be 16 years of age or over and be looking for their own Child Trust Fund. Alternatively, a parent or guardian of a child under 18 years of age is eligible to use the tool on behalf of their child. The process requires secure identification. Users must sign in with either a Government Gateway ID or a Gov.uk One Login. These login credentials provide a secure method for HMRC to verify the identity of the person making the request.

Information Required for the Application

Once securely logged in, the claimant will need to provide several pieces of information to assist HMRC in locating the fund. This includes the child's full name, their current address, and their date of birth. Any previous names the child may have used are also required. Additionally, the claimant must provide any previous names used by the parent or guardian if they are applying on behalf of a child. While the child's National Insurance number is an optional piece of information, providing it can potentially aid in the search process. Note that the HMRC tool form must be completed in one go and cannot be saved and returned to at a later time. Therefore, it is advisable for claimants to have all necessary information readily available before commencing the online application.

HMRC's Response Time and Information Provided

Upon successful submission of an online request, HMRC will process the information. HMRC commits to sending a letter within three weeks of receiving the online application. This letter will confirm which Child Trust Fund provider holds the account. This is a crucial step as it directs the claimant to the specific financial institution where their funds are held. The HMRC letter does not disclose the CTF balance. It solely identifies the provider. To ascertain the exact balance of the Child Trust Fund, the claimant must then contact the identified provider directly. Postal applications are also possible, but they typically take longer to process than online applications.

Alternative Paths to Discovery and Escalation

While the HMRC online tool is the official primary route, alternative free services are available to assist in finding a Child Trust Fund provider. The Share Foundation, for example, offers such a service, providing another avenue for individuals to trace lost accounts. In instances where the Child Trust Fund provider is already known to the family, perhaps through old documentation or a memory of the original account opening, the family can bypass the HMRC tool entirely. In such cases, they can contact the provider directly to initiate the claim process.

What to Do If HMRC Takes Longer Than Expected

Under normal circumstances, HMRC aims to respond to online requests within three weeks. However, if an applicant has submitted an online request and has not received a response within six weeks, there is a specific escalation route. In such situations, the applicant can write to HMRC directly. The postal address for this purpose is: Charities, Savings and International 1, HMRC, BX9 1AU. This channel provides a formal method for addressing delays and ensuring that the search for an unclaimed Child Trust Fund continues.

What Happens Next

For the estimated 750,000 Child Trust Funds that remain unclaimed, the money continues to be held by the respective providers. These funds will remain with the provider until the eligible owner makes contact and initiates the claiming process. The availability of free tools from HMRC and organisations like the Share Foundation means that individuals born between 1 September 2002 and 2 January 2011, or their parents and guardians, have clear avenues to locate these substantial tax-free savings. Accessing these funds at age 18, or managing them from age 16, requires proactive engagement with the provided services, potentially unlocking an average balance of around £2,200 for each eligible claimant.
