In reality its been a few decades since that aspect of the law changed, so new these days should be OK provided it comes from reputable supplier.
But on a rapid increase is the number of online shops or websites selling nonconforming electrical products. I note with fear that several chinese shopping sites are offering some very dodgy electrical items (probably falsely claiming to be CE and CAUK compliant) products with 13A pin configurations without the correct insulation on L & N connectors and plug tops that do not have a Fuse, and are under size in terms of gripping. wire cords with copper coated aluminium conductors, undersized for stated loads.
