So just been to see our NICEIC registered electrician. Apparently the radial spur has a fcu in the loft so okay. The cable on block connectors in the cavity was apparently the way my sister in law wanted it connected because there was no other way and this was how he advised it should be done! Asked if he thought this was acceptable he just shrugged and said how would you do it, err just fit an outlet plate. Asked about rcd protection he just looked and said board needs changing, I asked if he assessed the existing circuit protection, he said yes but just went ahead because it needed doing in a hurry. I have suggested he fit an rcd spur by the board which never occurred to him. I said I found it hard to believe he was going to issue Certification for compliance with Part P to which there was no reply. He is returning tomorrow to rectify all this but I could not get an answer as to how he connected the downlights but pulling one down is likely to cause damage. Sadly if he rectifies all this I won't be able to peruse it further and that is wrong because you should be able to complain to the scheme provider immediately.
