the one big advantage of Part P as I see it, is that it makes the work accountable, for almost every piece of electrical work done, the customer SHOULD have a certificate with the contractors details on, and those test results on the certificate should show that he has tested his work, it is there to protect the consumer, there is no way I would have done a wiring job without performing the correct tests before part P was introduced, and hopefully now, every sparky in the land should be doing the same, although I still find some who aren't.
I think part P is a mess, but I can see the reason why it was introduced
