NAPIT Certification Scheme Consumer unit replacement issues

Let your electrician mate sort it out how has it become your problem.

As above, your sparky mate needs to finish his job off. Don't bail him out

@Michael J can you clarify the situation here so we aren't playing guessing games.

He’s a close friend and was very supportive during my cancer treatment, I’m ok now though.

Splitting the ring is all you can do in this circumstance.

I bet the customer doesn’t even allow you to move furniture to access sockets though.

Have you double checked your mates work? He hasn’t done something daft in the CU and got legs mixed up?
Possibility of faulty rcd? (Swap it for known good one) or is it an actual N-E fault. What was the IR result?

I work closely with the electrician on many jobs and I get involved with design,installation inspection on1st fix and 2nd fix. Etc.
On this particular job he didn’t insist on a EICR prior to carrying out the work due to cost implications (my error I should have reminded him)
The original request was how to deal with the client.

all ready have

So your Mate fitted a new CU but did not carry out any testing afterwards was there an EIC CERT issued at the completion of the CU swap?? get your Mate back to rectify and explain his nistake to the client it's his fault this has happened

Thanks for the feedback.
Disconnected the ring in the CU and found a very low reading between N & E, causing enough imbalance to trip the RCD.
Original installation did not have RCD protection so the current flow wasn’t enough to trip the mcb.
I do not know what the original installer was thinking but the ring serves the entire house including underfloor heating.
I have suggested that when we can pinpoint the problem we disconnect that section and replace it with a surface mounted option. I suspect there could more than one fault, there have been a number of additions as when splitting the circuit both legs trip.
Hope this gives you an idea what is going on.

Hope the client agrees to the surface work, you have to make the client understand that cables cant just magically appear without some kind of disruption.
Too late but testing before teardown is the only way.

Your Mate, has he offered any help, Advice or offered to finish off whathe should have sorted in the first place, even though he was a help during your illness this should be passed back to him, tell your client to contact him, after all he is to blame. should have made sure all was OK prior to swapping the CU and issued an EIC on completion of the CU swap, thus negating the need for an EICR. IMO.

Totally agree

Yes he has taken full responsibility and is in contact with the client

Seems like delicate negotiation with the client is the only way of resolving this.
