Are there any Impact Protection Vehicle drivers here?

The first page I printed out and handed them was that Lantra page.

Their response was “Lantra are just a training company and will just say you need to do every course just so they can get money out of you. We can’t use that page to justify the requirement for training”

I pointed out that Lantra make the courses, and on that page you can find local training providers, why would a training company do that? And it was met with " we can’t use Lantra for definitive training requirements"
