Davesparks, thank you for your comments. I was unaware that I could have any input to the scope of the EICR, and even if I had, I would not have had sufficient knowledge to direct a professional electrician in any way. The fail on the shower light caused me to investigate, and obviously I'm glad that happened, as that is when the rather messy connections came to light. So, no blame being apportioned here. I needed an EICR, ordered one, got one, and it highlighted a problem for investigation. If, and I say if, there might, and I say might have been some onus on the electrician to check in an easily accessible loft space, the end result was fortunately the same. He did miss 2 very minor but visible lighting connectors, but I tidied them anyway.
Also, you are again correct in that I now recall getting the original EICR which of course showed the 2 fails...a fresh one was sent after the 2 fails had been addressed. I replaced the shower light with a proper one, with a transformer, all cables wagoed in a junction box, and cables clipped to joist.
