@definitive ”“Unfortunately we do not have a mentoring system in the UK.”
Other than things like Big Brothers, Big Sisters, there isn’t such a “system” in the US either. However, you can find someone who might serve as a mentor for your daughter in various ways. Here are some of the things we have done:
We use a “loaner dad” as we call him who we met through our church to help my son start to understand how adult men deal with the world. He has a ranch and a elderly car, so he and my son do various tasks related to both, and sometimes they talk. We also used a neighbor, the father of my son’s friend, who was mechanically inclined as is my son. The three would work on various vehicles and talk while working. Unfortunately, he died suddenly of lung cancer We also have as a mentor one of the SCUBA instructors who taught my son how to dive. He sets up special dive trips for several boys about the same age, and parents come along to sit on the beach and prepare a meal while the guys dive.
My husband as a Scout leader also used to mentor the kids in his troop, and other parents became involved and many also served as mentors. Girl Guides can sometimes provide a mentor to a teen girl. I was very interested in marine science and found two different science teachers who acted as mentors for me, so sometimes you can look to the school to help.
A mentor can also be an adult family member not directly involved in the household. When I was growing up for a while my aunt lived near us, and she served as a mentor to me during part of my teen years. Currently, my adult step-nephew and his mom serve as mentors at times for my son.
So mentoring is generally an informal arrangement even in the US, but it can be very helpful if another trusted adult can listen to the things your daughter needs to say but can’t say to you.
