You can no longer apply for a new Child Trust Fund because the scheme is now closed.
However you can apply for a Junior ISA instead.
More information on Junior ISAs is available at:
Existing accounts set up for a child prior to the closure of the scheme will continue to attract tax-free investment growth.
The child, friends and family will also be able to continue to invest up to £9,000 a year into the accounts on behalf of the child. However, no withdrawals are possible until the child is 18.
