palacie - you can have many thousands of hours on a PPL. Just because you get close to the requirements of a CPL doesn't mean you need to get one. There's no point.
For a start, there's the many more exams. Then you'll need a Class 1 medical which has more frequent renewal and tighter requirements than a Class 2. And then you need to keep the CPL & Class 1 current, and that's aside from the CPL training/skill test itself.
If you're never going to go commercial, you never need a CPL. (You can now instruct on a PPL licence also).
