Query over new circuit installation for Boiler, and Bonding question

[GLENNSPARK]

Somehow my reply got lost!
so here goes.

The certificate is incorrect for a newly installed circuit, and also new main protective earthing.
the fact it has not been supplementary bonded across the fire valve and filter may be because it doesn't need doing, which is genuinely possible if there is negligible resistance across them.

as for the testing, well as you are sure it hasn't been tested then I'd suggest a phone call to them first, they may be able to provide some proof or come back and show you the tests again.
If after this you still aren't happy then ask a member here to come round, at your cost, to check the work and validate the results on the minow works, if they can be proved to be wrong then a condition report limited to just that circuit could be issued and then you'd have the evidence you need to take this further, if in deed that's what you want to do.

my only concern now, is that the cert says the circuit is Rcd protected yet you state it is on the non Rcd side of the board, which suggests a failure on the part of the electrician

yeah...if this is the case...
then the characteristics of the circuit are false...
for earth fault anyway,...

Looks to me like the main bonding has been adequately installed.although it is preferable for clamps to be within the building rather than external,this may be because of practicalities on site. The only issue appears to be that a minor works cert has been used for a new circuit,and the RCD issue....but are you certain there is a dedicated MCB in the CU for the boiler?....a pic of the cu would be useful.

and if external 951s have been used?

How do you know for certain that no test instruments were brought into the property? I'm just playing devil's advocate here but unless you were watching them the whole time and knew what test gear looked like (which you indicate) then you wouldn't know for certain. I've lost count of the times I've opened my test gear up and been asked what it was.

yep...
my point at #13 trev...

I would think you have unnecessary supplementary bonding but it's not possible to tell definitively from here.

Picture of the CU, the boiler is 6th MCB from the left, labelled "Water Heater", after the Main Switch.

All tools that were brought into the house were in a small brief case style carry bag, so unless a suitable tester is small enough to fit in a standard jeans pocket without being noticed, I doubt very highly that any testing was done.

If the circuit in question is really the one you have stated then clearly you have a jackanory cert as they have given RCD test results when there isnt one...(assuming they have not stuck an RCD FCU somewhere).....Get on to NIC complaints,or otherwise their stated test results can easily be verified by another tester,perhaps there is a forum member locally who could verify?

You stated this is a new circuit.....surely the W/Htr circuit was there before?

My thoughts too

My guess is they used existing water heater circuit via a RCD fused spur unit local to the boiler especially if the boiler replaced is a combi & is close to where the old hot water cylinder used to be. Or the boiler has been located next the the existing hot water cylinder. Either way dont see much wrong with that

Water Heater Circuit was labelled on the CU, but not installed, as this had previously been removed before we moved in. Heating system has had a complete overhaul. I assume the Water Heater relates to the Immersion Heater that would have been in the hot water cylinder on the old system.

New boiler is located at the opposite end of the house, under the stairs. Originally, it was located just inside the side door, hence the minor building site in one of the pictures through the door. No RCD FCU has been installed, just a basic Switched FCU under the stairs near the new boiler.

I immediately thought the certificate was mickey mouse / jackanory / laurel and hardy when it arrived with RCD tests on it, as it isn't and never looks to have been RCD protected. I have verified that the boiler is on the stated MCB, simply by flicking the MCB into the off position, and watching the boiler neon tell-tale extinguish.

I will be on to NIC in the morning, the company in question seems to get a lot of referrals from the plumbing company, so I will be ringing those too!

TBH fictional certs are rife....I've also seen one with rcd trip times with out an rcd in the house,and recently saw one with ring circuit readings for a radial!
That does not excuse it,even more so as this is an approved contractor rather than just a DI.....make sure the NIC take action,follow your complaint up and dont be fobbed off. As an approved contractor ourselves this sort of thing gives us all a bad name,

 

[Mike66]

I think most probably the NICEIC will want you to contact the contractor first to see if it can be sorted out amongst yourselves. If you get no luck via that route I believe they will then step in as arbittraitors.

Not that I am speaking from experience, it's just that, that is how I understand the system works.

As NICEIC contractors they will have to keep a register of any complaints that they receive about the technical aspects of any of their work but not contractural

 

[Mike66]

I forgot to say. If you go on the NICEIC web site it may give you advise there on what you should do
