Failed resistance test

[woodbutcher32]

Evening all, during a recent electrical survey my
small terraced house failed on a lighting resistance test
(came up 0.6 when im told it should be at least 2)
can somebody please give me some pointers on how i can test this and possible causes?
Cheers in advance.

tel,
You're cheaper than me then!

The house is in Co. Durham, the contracts for the house sale are due to
be signed tomorrow so im pretty desperate, the same spark did
the inspection so i feel obliged to just get him to do it so i can
get the certificate to the solicitors.
Im not a total novice at electrics having rewired the socket ring and installed a new
cu etc. so i kinda hoped i could find the fault myself.
Could it possibly be a trapped cable or simply a loose connection in a junction box
or pendant?

any outside lights/ sockets? water penetration?

woodbutcher,
If this is relating to a house sale then you may well need it "signed off" by a "registered" person, else the contracts may well not go through.

An N-E fault is often a stupid wiring error, however, if the house is "all RCD" then you have other issues.

Well there is a few members in Co Durham and one of them I would trust with my life nevermind an IR test and to provide a cert. Let's see if he's on line tonight.

Yeah the lender is insisting it is signed off, there is an outside light with 3 lives connected together, the bulb is being fired by 2 blacks and the remaining black, the switch inside is working on one cable whilst the other is just connected together, everything seems to work fine, I haven't touched any of this wiring, it does seem suspect though!
The wiring is 15-20 years old and is All in pretty good nick.

Sorry just to add its a split board all rcd

 

[netblindpaul]

It sounds like you need a full detailed PIR by a competent person and then see if the lender will accept this as suitable evidence that the wiring is acceptable, they may not, they may still require an indemnity policy be taken out.
Also, they can insist on the PIR being undertaken by a scam member, and worse they can specify the scam, after all it's their money, they are a private company, thus they can put whatever terms they wish on the transaction and there is no legal recourse to refuse them.

£50 quid an hour in Durham is pretty high

more like 20-25 up here mate! even £30 is pushing it!

The vendors solicitors are they happen to be looking for the certs for the jobs you have done?

Durham,
Whilst I appreciate your point, why do you feel that the company is over charging?

A previous employer of mine is on around the £90 per hour mark and they get this country wide, because the guys are good, they carry the kit, they have access to the spares and, they have the training, backup and competence to do the work efficiently, so they can charge more.

I do think that if the company can get £50 per hour then that is OK.
Perhaps they have high overheads and massive competencies.
They may be able to do the work quicker than you so, what would take you 3 hours at say £30 per hour could only take them 1 hour, thus giving the customer a £40 saving!

Sorry, but I feel criticising others rates and charges is unfair without all of the info, I could claim that if you are charging £20 per hour that it is too much, I would have no grounds for that, so IMHO it is the same thing!

:winkiss:
