Its not just USB sockets that can get fried.... Electronic dimmer switches, PIR sensors, LED lights... nothing with electronics like having the 500vDC pumped through it.

Thing is, the EICR (apart from the erroneous comment about requiring an RCD for fault protection) does not indicate a new CU is required.I knew I needed a new CU because the old one has MCBs and not RCDs. Should I have done that before the EICR?
For better or worse, this saga has thrown up the IR/earth leak problem that I didn't know about before.
Disagree with your first paragraph.I knew I needed a new CU because the old one has MCBs and not RCDs. Should I have done that before the EICR?

No as the contractor must test anyway before putting in a new CU as the possibility of pre-existing faults would trip the RCD and then you are at square on having to do tests to find out the fault. Anyway surely you were due a new EICR?Should I have done that before the EICR?
I do always wonder if there is a reason why the SMPS in these sockets isn't fed from the switch. It seems to be a simple solution to the problem and means you're not leaving the power supply permanently on.
Just been to see my tenant, who reported that after the inspector left, they realised that their fridge-freezer wasn't working. The engineer came and reported that the circuit board was fried. So it seems that the IR tests were done without unplugging everything...Its not just USB sockets that can get fried....

It's not nonsense - it is required to code any lack of RCD protection where now required with a minimum C3 observation (which could be given a more serious observation depending on the details).I'll ignore the C3 on cables not buried >50mm, it's nonsense.
Neutral is a live conductor .One year ago, not 10!
Main leakage was neutral to earth, not live to earth.
And lots of fun finding extension leads with surge protection stuffed behind beds.
Now all clear for new CU - thanks @Wilko
