No Fly leads anywhere and no lugs to do so, not on sockets either, just the fixing screws to give continuity.
Ok, reading Reg 543.2.7 an earthing fly lead is required in each accessory. And for safety, I would say it really should be there in an outlet. So C2 from the judge with red wine in hand.

Lol, I like the red wine, however, in terms of resolution, whats the most efficient way to resolve?

but given the choice of no earth or an earth
As far as I am concerned they could have no earth. The DNO left them with no earth, that is their problem and liability. It is for you to be on top of them and make sure they do the right thing. Your must understand that as @westward10 said, if the compression of the clamp causes a short it can be fatal to you and is in no way acceptable morally or legally to do that. I have had this before and got them back the same day with the right kit and do the job properly. Don't let them brush you off. If I were you I would take that clamp off in fact, but then I would never put it on in the first place I'd be too scared to. Don't mean to be mean to you, but I feel quite strongly on this subject and feel it is important to say what I said, no offence meant.
 
Do the back boxes have earth terminals.

Hi Vortigern,

No offence taken, im new to doing EICR's and have recently passed my 2391-52 but not new to domestic electrics, that said, am continually learning and always want to do things the right and best way, hence the question, appreciate the response. Ive arranged a return visit to remove it and will get onto the DNO, will they talk to me or want to only talk to the occupier based on your experience?

Thanks,

Gringoking

Hi @Gringoking88 they will listen to you and you are the only one who can talk to them. ESQCR reg 24 absolutely require them to maintain the earth so they cannot wriggle out of that. Not to say I go in with guns blazing, I prefer the charm offensive. Normally the DNO, especially the supervisors and guys on the ground are perfectly ok with supplying an earth and no probs as far as I have experienced. The householder can't really tell them as usually they haven't a clue as to what the hell it is all about. It's when you get the desk clerk who says the computer says no, you have to quote regs to them, and usually you get to speak with someone who knows the runnings and gets it sorted.

Totally agree with Vort, never put a BS951 type of pipe clamp on a lead service cable. PILC cables are quite durable in some respects but they are ultimately made of soft materials that the clamp can distort and crush. And if there is something you really don't want to have short out in front of you, it's a public supply fused at 400A with a prospective fault current of 10-15kA. And, the lack of permanent spring tension in the clamp means the connection might give out after a while anyway as the lead creeps.

Re. The high PEFC, I don't know that MFT but it looks like it has a test lead resistance null function active. Does this apply to the cable used for loop impedance tests? If so, you might have an incorrect null programmed that is offsetting a higher resistance than the leads fitted. This will cause it to under-read the impedance and overestimate the fault current.
