The 12 month manufacturer's warranty is in
addition to your statutory rights as a consumer.
Under the
Sale of Goods Act 1979 (as amended), your contract is with the retailer (Amazon).
It is the responsibility of the retailer to ensure that any goods sold "conform to contract": they must be as described, fit for purpose, of satisfactory quality, etc.
For
up to six years after purchase (depending on how long something would be reasonably expected to last), the consumer has the right to demand a repair or replacement.
For the first six months after purchase, the onus is on the retailer to prove that the goods did conform to contract and are not faulty.
After six months, the onus is on the consumer to prove that the goods did not conform to contract and are faulty.
In addition to your rights under the SoGA, EU law also stipulates that you have a two year warranty on certain items. Again, this is with the retailer not the manufacturer.
