DrJones,
Are there actually any p2f schemes in place in the UK
Some UK training organisations do offer this. (There are several links which I probably won't be allowed to post here. But you can find them easily enough through google).
Most send candidates to Europe for the flying.
I believe at least one scheme is (was?) run by a current EZY TRE.
Whether this 'true' form of P2F is what the OP was talking about is another question.
edit...
many are scams which take the money but dont deliver the flying, (one to google). No sane person would go down that route so it is effectively dead in the uk.
