I must be lucky, last job I did, first fixed cables, came back with no interaction with guys doing the boarding (customer was project managing his own project), expect a nightmare finding cables etc....instead....level lines drawn, 80% of cables pulled through holes, others marked where they were....only niggles - socket ring in the utility room extension had a 2.5 spur to an SFCU for an exterior light, instead of drawing all 3 cables out at once, they had drawn them out in 2 separate holes (no one had considered to phone the spark to ask why there were 3 cables there.... oh well 2 holes for the plasterer to sort, stuck the socket backbox dead centre between the 2 holes...where I had planned for it to be all along.)
Other niggle was for the living room lights (fcu off the living room ring at socket height to light switch at normal height - underfloor heating so couldn't go below, customer had laminate floor above so couldn't lift boards upstairs) Feed cable was below a noggin, supply cable above it, ended up having to remove the plasterboard from that wall (thankfully not skimmed etc, just screwed in place) to get the feed cable above the noggin, after spending 25 mins trying to pull it up through the drylining box hole and removing the skin from my knuckles from the harling on what was once an exterior wall behind the plasterboard.
Also the geniuses removed a socket and joined the wiring with 5amp terminal strips...well the live and neutral, the earths they just left alongside each other..........
