We're fucked
The plus side of leaving the EU - I'll no longer have the whole EU consumer rights legislation incorrectly quoted at me by people who don't realise the UK is exempt from it because of it's own superior legislation.
I was looking into this stuff a while ago (my PS4 died). I think there are certain specific areas where the EU Product Directive does offer protections not offered by the UK's robust consumer protection laws. Or at least uses more specific language.
The UK sale of goods act says stuff has to be fit for it's intended use, whereas the EU Product Directive specifies that if it can be proven to have been faulty at point of sale, then the retailer must repair/replace/refund for the lifetime of the product.
The sale of goods act language is a little vague in terms of time, because "Fit for use" doesn't really specify a length of time, whereas the EU Product Directive specifies that it's for the lifetime of the product.
This is from memory so I might not have the details totally right. They are covering slightly different scenarios anyway, but both seem to be useful consumer protections to me.
