TN-S earthing issue

[KevinH]

I have just carried out an EICR at an old property and found this issue with the main earthing conductor.
It has a TN-S system but the earthing conductor emerging from within the taped up tar coating just before the cut out is only 4mm2 of (what looks like) steel wire armourings. It is 100mm long connected to a small earthing bar. It is not the more popular lead sheathed with earth clamp moulded to it.
My question is, as there is no way to upgrade it without getting involved with DNO cable/equipment, should I just leave the 4mm earth and earthing block close to cut out, then upgrade all earthing from that point on.
Just to point out, at present there is only 4mm earth feeding a BS3036 consumer unit (due for replacement) with 6mm earthing to gas and water. The Ze reading is 0.17 ohms. Adiabatic calculates earth should be 6.19mm2.
Also, what codes for the DNO's undersized earth?

What can you do, you’ve done a EICR,your PDH & QS signs the certification where appropriate,you’ve signed your bit.
You’ve noted the observation you may have coded it, then it’s there duty to do the necessary remedial’s,if required.
As an employee you are then asked to do the works,if those works are not assigned to you,that is not your problem.

So if you if you found the DNO earth had failed or the service head was leaking bitumen or crackling am I thinking you would code it and walk away from site and leave your QS to deal with it!!, surely not.
The book stops at the guy who was onsite not the QS if you code something incorrectly or fail to note something it's not your QS that will be talking to the person in the funny wig if something goes wrong.

As an employee ask yourself would your employer back you up or run away and save his own skin should the **** hit the fan, and the only time you will ever find out is when it happens, Take care

You are now asking a different question,which would have a different coding.
Any code 1 would require immediate action.
Regarding my court case,I’ve done nothing wrong.

i would say that if the DNO earth had failed in some way, you might have a load of C1s or C2s as Zs readings could be unacceptable (although bonding could affect these). You are there to report on the installation,nothing more. Once you have passed that report to the higher ups, and maybe left a copy with customer (all depends on you company's policy) you have fulfilled your remit. Being self-employed myself, the responsibility is with me to advise the customer on remedial work (in writing and signed by customer) and it's then the customer's responsibility to act on it. being employed, it's the employer's responsibility to do this, not yours. Also wsoth noting that we do not have the authority to disconnect any dangerous part of an install, unlike gas. all we can do is issue a danger notice if appropriate. end of the day, it's down to the customer to act/not act on the findings of the report.
