If spotting dodgy imports of dangerous light fittings etc was not already hard to do, and quite contentious, it seems that after Christmas, as well as CE documentation, we may be expecting to find UKCA or maybe UK(NI) marks depending where you live, as of course anything coming in from Europe will now count as an import, and the person bringing or mail ordering it into the UK will become responsible for the import paperwork.
