Everyone's personal tax and business circumstances are different and that is why all those who want to reclaim the VAT should seek professional advice. There is not, and cannot be, one definitive answer to all the myriad of questions that have been asked on this thread.
However, as a general rule ... yes, you cam reclaim UK VAT on UK CPL training if your subsequent business intention is to be self-employed in the UK after qualification.
