Below is a picture our guy took from the PIR I mentioned earlier, the 'surveyor' had ticked a box for RCD protection among other things:
The enclosure was unfixed on a shelf below the CU exactly as in the picture.
Our guy removed the lid, lifted the enclosure to look inside and the red line conductor fell straight out of the terminal!
I wonder why lights were flickering when the shower was running!!!!
The PIR has 39 defects comprising of: 20 X code 2, 2 X code 1 and 18 X code 4 not bad for 8 circuits!
There were class 1 light fittings with the cpc's in connector blocks, pushed into the ceiling, no main protective bond to the water service, smashed accessories, and on and on!
The main point is that the 'surveyor' had ticked 'OK' for 4 categories that were far from OK!
If it goes to court and we get the expert witness role, I'll do a court diary thread!
