It is £20bn year. As explained "HMRC have looked at the new declarations and costs for five different groups of businesses differentiated by their trade volumes and use of intermediaries. Costs vary between £15 and £55 per declaration. The additional number of estimated customs declarations is 205m for current intra-EU trade."You see no reason to think that £20 billion isn't an accurate estimate? I'm not sure what period the £20 billion is supposed to be spent over - is it yearly? Let's be generous and assume it's for a ten year period so that's "only" £2 billion per year. If we employ people full time for this task (whatever it is) and pay them each £40,000 salary to do it, that's fifty thousand people employed doing this work.
Maybe you think that's reasonable? I don't.
The remaining charge is for extra rules of origin costs which has been calculated from "Ciuriak (2014)which concluded that a plausible range for only the administrative costs imposed by rules of origin is between 1% and 7% relative to the value of the exported good under preference. Cadot et al (2006) concluded that the total trade weighted costs imposed by rules of origin is between 7-8% for trade eligible for preferences, for the two rules of origin regimes they consider in their analysis."
Rather than resorting to argument from incredibility and innumeracy perhaps you could suggest where the official Government estimates are wrong.
I will even offer to help in that using your £40k a year worker. It will create 500,000 extra jobs, albeit that it for current trade so those extra jobs will not result in any extra sales. To cover the cost of extra employees prices will have to increase and that will reduce demand for sales. Lower sales in turn means the additional costs are lower . So rather than £20bn a more realistic figure is £17-20bn.
Oh wait, that is exactly what Jon Thompson said.
