In the UK (and the rest of the EU), if you buy an item as a consumer, the seller is responsible for the item working for a reasonable amount of time. That time runs out eventually, and then you have to pay for a repair yourself. For example, a computer might be expected to work for two years.
However, even after two years I expect that I can repair the item (at my own expense) to use it for longer. If it turns out that a 26 month old item cannot be repaired anymore, can I successfully claim that this is a fault on its own, that this fault ("cannot be repaired after two years") was present when the item was purchased, and that the reasonable time that a computer can be repaired is significantly longer than two years?
