Minimum age for a young person to consent to their own medical treatment is 14 years and nine months old, as long as the treating practicitoner (in this case the GP) is satisfied that they are able to make a responsible and informed decision at that age.

If there is doubt, then a practitioner will usually seek the permission of the parents up to the age of 16, at which point they are not required to have parental permission, and in fact are also not able to disclose any information to the parents without the consent of the child.
