I think Robert overstates the practical implications of the issue.
Most likely, as with so much affordable equipment out of China, its never been tested. Assuming halfway sane design its going to be at least close to the regulations and probably inside them for normal use. With EMC its generally the edge cases that catch you out with excessive emission if the basic design is sound.
If it really is well out LiDL are liable under the wider sales of goods act provisions as its not suitable for the purpose its sold for and is misleadingly described. Needs at least a big "for industrial use only, not to be used in a domestic environment" banner on the box to get out of that one. Anything in a supermarket has to be considered consumer goods and any outfit the size of LiDL has to be considered an expert supplier.
Be most interested to see what the version sold in German stores has to say about itself.
I do wonder if there is a suitable "universal" filter that can go on the workshop (or house) incomer to stamp out anything trying to go back upstream to the supplier. VFD driven washing machines et al are becoming more and more common. Not to mention umpteen (cheap!) switch mode power supplies which can be worse. Solar panel inverters probably aren't blameless either.
