Currently EU and UK sorks on the rules for leaving EU. In practice this means that UK follows EU rules until 31 December 2020. What the new rules will be is not know currently. This also. means that UK notified bodies will exist until that date easing up some of the burdon for the rest of Europe. Suggestion to go into MHRAs webpage and check status now and then. Also good to check what the Travel requirements Will be in case you want to spent new year in UK. Easy to get in but might be harder to get out!
