I looked into this not to long ago. Here in the U.K. the tax law is quite clear, You can not claim back any training expenses that qualify you to progress. You can claim for training expenses that allow you to continue, for example changes in the law or safety regulations that require additional qualifications to be gained in order to continue in current position. So if your starting at the bottom the first thing you will be able to claim is your medical renewal.
I think you should get a t-shirt when you leave full time education in the U.K. with the words "Qualified to be Shafted" printed on it................... Oh would the last one who leaves please turn the light off.
After a full tax investigation going back 6 years, maybe I am just a little bitter !!
