Oh here we go... Pete, the question arose because (if you read back) there are 2 such sockets, one on a plug top one wired into the back of a plug, both wired in flex. The original question was actually about flex not about whether or not this should be 1) defined as an extension lead and 2) should extension leads be part of an EICR.
I am quite aware that the EICR report is for the fixed wiring only which is why I questioned your response. You wrote a poorly worded and confusing answer (by your own admission) and then proceeded to question should I be doing this type of work because I responded to your post.
Its people like you that really make we want to quit this forum. I'm sure you may offer some modicum of advice on threads here and there and you may be respected by some of your fellow old school electricians forum buddies who also offer the same old type of condescending, non-constructive, off topic comment such as "should you be doing this sort of work".
I question whether you should be commenting in forums but this country is all about freedom of speech so I suspect even those who struggle to convey themselves in a civilised and educated manner must be allowed to provail. I ask that since you don't know me, my knowledge, my experience or anything else about me, you don't question my motive, you simply either respond to the original post, or don't comment.
@Spoon thanks for your discussion and input into this thread.
