I don't think people realise how ridiculously difficult it is to cover things up. Especially something like this with hundreds of people involved. You only need one person to blab some credible information and the hat's out the bag, then more come out of the woodwork admitting to its fakery. If this was fake then it stands to reason other shows by Derren will have been faked, so those will have people involved in the production coming out to say it's fake.
It would come down to Derren having to shell out millions of pounds in order to keep their silence and he doesn't have that sort of money to give away, nor would everyone involved accept bribery anyway.
