What the heck does this mean???!!!!!Watch
Unfair contract terms act 1977
"In a consumer contract there can be no exclusion of liability by reference to the terms of a guarantee in respect of defects which have been caused by negligence in the manufacture or distribution of the goods" (s5(1))
So, a consumer purchases a television. The guarantee which the shop gives with the television states "This guarantee excludes liability for negligence in the manufacture of this product." Consumer comes home and television doesn't work. Goes back to shop, who say "Sorry, we can't help you because we are not liable for defects caused by negligence in manufacturing."
This provision stops shops from doing this.
I am assuming you know what exclusion of liability and negligence means...
