When does a domestic property need a rewire ???

[Dozer 73]

see a lot of different threads on here , where people asking for advice on old installations , one tonight even about moving sockets installed in the70’s in metal conduit and 2 core cable
It’s a funny game where not every one thinks the same , know wiring lasts a long time but the accessories get worn , make bad connections to plugs , lamps , switches etc
Personally I’m quite quick to advice a rewire , not for my personal gain tbh
Just wanted to know at what point other people advice a rewire

Live/Live on model forms means exactly that. It relates to tests between all live conductors. In a single phase installation this is merely line (phase) to neutral. In a three-phase installation it is all phases to neutral, and also between all phases.

Likewise Live/Earth relates to all live conductors to Earth.

NICEIC schedules (and probably others also) have separate columns for phase - phase; phase(s) - neutral; phase(s) to Earth and neutral to Earth.

Do you think we get paid enough for all our knowledge and skills and the fact your neck is on the line with test sheets etc , well as an employee

Department store yes I agree , every job will be different and approached different by the inspector , a big work shop with lots of 3 phase equipment for instance , you would have a different approach , also you would agree a percentage of circuits to be tested , I’m only giving different opioids for arguments sake

OK, but I can tell you right now that even for a domestic installation one of the things I always have in my terms when quoting as an agreed limitation is that insulation testing will only be carried out between live conductors connected together and Earth.

If they wanted insulation testing to be carried out between live conductors I can assure you that it would have a severe impact on the price quoted. I also don't believe that it would be particularly beneficial - certainly any perceived benefit of taking this approach would not in any way outweigh the additional cost.

That report doesn't look like it's worth the paper it's written on...I think you should get a 2nd opinion before you make any decisions. @Andy78 Is your neck of the woods and really knows his stuff, if I was you I would be sending him a pm to see if he could take a look/quote.

I must have a peek at this report - I still haven't had a chance to read it!

Slightly confusing how with no Earthing arrangement, and no connection between the MET to extraneous conductive parts either, how Zs values have been measured on the final circuits.

Certainly the report is not good. At all.

that may paint a picture on some of my early comments , basicly looks like he’s written it off on visual ( write or wrong who knows ) and done a bit of paper work to back up his desicion
Hey presto hopefully 2500 ish in back pocket

Went round last night Lee.
Basically the last lad had spent 15 minutes under the stairs, no presence at end of circuits, and charged £70 for what he called a full EICR. He had fabricated all Zs results and even circuit descriptions, then quoted for a full rewire. The rewire price was a worryingly low amount and the customer won't be having his company again after being given a lot more reliable info.

He had recorded no main earth and left the property. There was a fairly new DNO head with a viable sheath connection ( Ze o.27 Ohms)and DNO supplied MET about a foot under the CU. I connected it up and recorded good Zs results at sockets in all rooms.

The last guy failed to spot the presence of several rubber TRS cables with no CPC still in use. The customer, having a good bit of self gained knowledge, had even asked about rubber cables but the fella said there were none.

The customer had already arranged for a full EICR asap at a proper rate with a local firm who have a 25 year history and good local reputation.
Had it been less work I could have got more involved, but I'm just catching up after having some time off with our new baby and the customer would have had to wait a few weeks, not great when things need addressing sooner than later.
I'm happy to have been able to at least re-instate the earthing conductor and give the customer some advice.

Scary

After a rewire this guy could leave it in a worse state than it was

Fair play to you for going round , some one buy the man a pint

£70 for a full EICR on a house - thats a warning sign, irrespective of the remaining content of this thread.

For any home owners / home buyers who think £70 will get them an accurate report - it won't .......................

£70 may just cover the hassle of a visual inspection report (which in its self is a waste of money as it doesn't actually test anything...)

No need, the customer paid me for my time and advice
