For those with experience of putting their children through the independent/private system in Scotland - approx how much would you normally expect to pay in additional costs over and above fees (as a % of fees) on a yearly basis? This includes optional and non optional costs and other things that might not be so obvious. For reference I am thinking about a city day school for secondary. This isn’t an affordability issue. I just like to have all the facts and hate unknowns. I am getting lots of conflicting information. I guess that trips are hard to quantify as they vary so much but a rough idea would be appreciated. Thanks.
