Scarifying the lawn is a common job here, even if you don't have moss you will have thatch so scarifying will help anyway. I will be doing my own lawn soon, then forked and top dressing, I review the lawn in spring and normally do it all again, I also verticut the lawn once or twice during the growing season just to keep on top of the thatch / moss and to simulate growth.
You do have a good amount of top soil for the water to drain away. How soggy is the lawn after rainfall? If so what Dave recommended hollowed tinged / forked would be the way forward with a top dressing of sharp sand
Lawns around here are getting worse for moss due to the wetter and wetter summers we are having.
I find lumps of concrete / stone and clay under my lawn
