The list of Customs training providers was published in May 2020 for heaven's sake. When I worked for HMRC many years ago, the basic training for a Revenue Executive took two years. Even for the clerical grade below that it was one year.
If that list had been published in May 2018 then we might have been in with a chance of implementing some decent training.
But why does anyone need training for frictionless trade? Two of the three providers I looked at don't specify their fees, the other one charged £249 for a one day course. So for a small firm which will ideally need to train two people that's virtually £500 before they even start, for something which is now free. Perhaps Clavinova could cut and paste something which tells me why spending £500 instead of £0 is a bonus? I can't see it myself.
