For us it would really be a choice, either fee-paying secondary school and they get big debts if they want to go to Uni, OR state school for secondary, but we can make sure they leave Uni with little or no debts. We can't afford to help with both.
We might end up doing this. If so we will worry about university when it comes to it. However, realistically, mine are likely to inherit some money from grandparents at some point, so hopefully any debts from university can be offset by that.
