UK Opinion on these pics please

[Andy_Reynolds51]

Hindsight is a wonderful thing but gives some good learning points. Best to test the installation before conducting any works to see if you will inherit a problem. Best done with the customer and other trades out of the way and not interfering. With a change of consumer unit you may not have the length of cables required to make it look good or follow the convention of highest load next to the incomer but have to go your best when under the scrutiny of other trades and the unqualified internet experts. Testing upon completion also helps to defend your position especially as other trades continue to work on site. It is possible some disturbance may have occurred unbeknown to them or others. Due to the delay of four days before a problem is noticed it could be weather related - outdoor lighting? Could it be component failure, even if new equipment? Could be the neutral of one circuit being returned to the other neutral bar - split load board but has been known. Interference, additional circuits or modifications since departing site? Some things to consider.

this is why it's imperetive to take pics of your finished work. THEN IF ANYTHING HAS BEEN DONE (BY CUSTOMERS OR OTHER CONTRACTORS/TRADES), you have proof of how youleftit.

We always take pics of our finished work and have now started using stick on seals that can only be removed by cutting them - so you know somebody has tampered with the CU

That's a good idea. Where do you get the seals please?

Joking aside, I'd like to hear what the final outcome is @ Apple1973 and hope you can resolve it satisfying all parties.

Something isn't ringing true with the OP for me, there is no clear reason why the customer wants a refund, the language also seems a bit strange my wife would talk to me not confront me,
Those points aside we are told the RCD tripped 4 days after install and keeps tripping but with no indication of the frequency or timing of the continual trips
Another electrician has apparently unsuccessfully looked for the fault after the OP's husband so does this fault really exist on the fixed wiring as 2 electricians haven't found any reason that would cause the reported issue
I think until the electrician involved can post his account of events leading up to the customer requesting a refund it is difficult to make a judgement
