The Sale of Goods Act doesn't give you a 2 year warranty at the Genius Bar. the SGA is about the buyer and retailer, not the manufacturer. And it only covers issues present or presumed to be present at the time of sale. And the latter is only presumed for the first six months. After that it is on the buyer to prove to the retailer that the issue was there and not replaced/repaired.
Bring a phone to Apple over a year out that has had no reported issues of any kind and try to quote SGA at them, even if you bought it at Apple, and you will be instructed to have your lawyer contact theirs.
I will state, once again, I used to work in an Apple Store, was trained on how to handle the applicable EU-wide Consumer Law and Statutory warranty information, which is available here. I have also made a claim through this coverage on my iPhone 5. It was as simple as saying well, I bought it in an Apple Store, so I should still have coverage? and then the bar appointment continuing as normal.
