Not me but a mate has a manufacturing facility in spain and in somerset doing the same thing
His opinion was basically "if you go to Spain and treat it like the uk where there are regs and you have to follow them, then Spain is worse and more bureaucratic - however when you realise none of the locals pay any attention to most of the regs, you realise that actually it is less burdensome"
I think as Brits we are generally of the mindset that rules are something you follow - a lot of other cultures have a different perspective. Therefore our regulatory approach to set a bar we know most will exceed, other appear to have the approach of setting "aspirational targets" in the hope people aim somewhere towards them. A brit mindset there is creating a load of extra work for yourself
(ps to put a brexit slant on this look at slaughterhouse regs - directive said slaughter under veterinary oversight, we legislated a qualified vet oversea every abattoir thus shutting a lot of smaller ones, the French brought in a veterinary oversight qualification for head slaughtermen and covered it that way)
