The EU legal guarantee allows consumers to request, normally within 2 years of purchase, repair or replacement of defective goods, or in some cases a refund. It is mandatory and to be provided at no extra cost by the seller. However, commercial warranties offered against payment are becoming more and more common. But are they worth the extra cost? Do they add to the legal protection in place in the EU, Iceland and Norway? The ECC-Net has carried out 342 checks in 25 countries, screened 104 websites, contacted 127 shops and surveyed 543 consumers online. The results show that not all commercial warranty offers go beyond the legal guarantee and that they contain numerous exclusions. They are most useful when they cover damage from accidents or misuse of products. On the occasion of World Consumer Rights Day on March 15, the ECC-Net is publishing its report on the application of legal guarantees and commercial warranties in the EU, Iceland and Norway.
