Martin Lewis explains how to track down lost Child Trust Funds - you could find thousands

The tracing service is accessible through the government’s website, but there are a few steps to consider.

Firstly, Britons should have their Government Gateway User ID and password to hand, but if they do not, then they can create one when using the service.

Thirdly, people will need to fill in the form online in order to ask HMRC where the account was first opened.
