I just tried to send back a faulty dimmer switch to Screwfix; supplied last November as a replacement when the previous one failed. They declined on the basis that the original purchase was in Feb 2004, ie more than 12 months ago.
I'm not unduly concerned given the low value of the item, but am still interested on a point of principle... some weeks ago this was discussed here: if something comes with a 12-month warranty and is replaced, I'm sure a couple of folk reckoned that the 12-month "clock" restarted with the supply of the new item. Is that definitely the case?
As I say, not particularly fussed about a £5 dimmer, but I would have been seriously pissed off if this had been, say, an expensive power tool.
