Child Trust Fund question

I had a letter from the child trust fund for my daughter who turns 16 soon in sha Allah.
Completely forgot about it, the govt used to offer them free for every child back then with a starting fund lf £250. It has now reached £450 with Family investment management fund limited.

I am wondering if this money will be halal to keep ir should I just give it away in charity when it matures and available for withdrawl?

جزاك الله خير

Hello I’ve just turned 18 and received my child trust fund and they gave me a prospectus about what I can do with it and what it was invested in. And it Said in its own words " the HSBC CTF and the HSBC Matured CTF invest in a fund which invests in stocks and shares" as you can tell it doesn’t say it invests in Islamic stocks and shares.

Jazakallah Khair
Doesn’t seem as though it would be halal, better to give it away in charity to be om safe side
