See the whole thread above, but in summary:
You can register a limited company and reclaim the VAT on professional training (so not the PPL part). However, you need to be planning to work as a professional pilot and to charge VAT through your limited company for said work. This means that if your game plan is to get your CPL and IR, reclaim the VAT, and then go job hunting on the North Sea, you are going to have a problem.
