Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what is the number of unclaimed matured HMRC-allocated Child Trust Fund (CTF) accounts which are included within the total quoted in the HMRC press release on 30 September 2025 for all matured CTFs which have neither been claimed by their owners nor automatically transferred.

Information on Child Trust Funds is available in HMRC’s Annual Savings Statistics.

We cannot answer each element of the 2 questions as HMRC does not receive a breakdown of unclaimed matured Child Trust Fund accounts from providers. This means we can’t identify which CTFs have been HMRC allocated and transferred into ISAs, nor breakdown the figures shared in the press release on the 30th September.
