The CU was changed on Friday of last week, the 28th April.
The electrician is coming over on Monday to resolve the problems.
Surely the RCD on a new CU is active on both live and neutral? Whereas it might not pick up a complete line reversal cos "things remain in balance wrt earthing", surely it would pick up a fault even on the neutral line? Does the RCD switch off both lines or just the presumably live line? If only the live line, then that doesn't seem like a well planned solution to me - for an RCD device to be fully safe, it has to switch off both live and neutral, or am I misunderstanding? It is dealing with a fault, how does the RCD know the nature of the fault, it's job has to be to cut off any possibility of current reaching the device or appliance, that should mean cutting off both live and neutral, in my humble opinion.
The point raised by mache about a faulty washing machine etc continuing to be live due to the neutral line issue is worrying. Won't the earthing system within the appliances keep the outside surfaces safe though? Also the issue of the Edison screw bulbs having a live screw casing is worrying too, although we have few of those and nobody will go near them until the electrician has done his stuff.
As a final check before leaving, the electrician inserted a socket tester. In every location tried, the socket tester showed L&N Reverse.

Sounds part Irish part Aussie to me, but they did a good job editing the expletives out of the video. Experience tells me there would have been considerable colour around the time of the faultLove the video, not least cos it reminds me of the times I worked with Australians in the Far East!
