Content Control is a legal requirement
Really more for interest than for the particular problem here — currently, the provision of a child profile is not a legal requirement in the UK. Instead, it's something which the mobile operators agreed to provide (on a self-regulatory basis), after pressure from various groups and bodies. There's currently debate (by way of a private member's bill) as to whether there should be a legal requirement, though.
