Query over new circuit installation for Boiler, and Bonding question

[steviec_lj]

Hi folks,

Please do excuse me if this is in the wrong area, it covers a couple of topics so I thought it would be best to pop it in here.

A little over 2 weeks ago, we had a brand spanking new heating system installed, and I cannot fault the lads that came and did it. Everything was tidied up, they moved whatever they needed to, etc, etc. Unfortunately the same couldn't be said for the electricians that eventually came out and connected the
boiler, motorised valves and room stats up. If there were a rogues gallery, I could post a number of pictures up.

The main issues that I currently for see, is the bonding arrangement that they have installed. The main bonding for the water main seems satisfactory, and is connected after the stopcock, within 600mm of where the main enters the building. The have piggybacked from this, through the wall to the oil pipe, to a point on the oil pipe that is some 4mtrs away from where it enters the building and 2mtrs from an external stop tap. They have added bonding to all other pipe work near the boiler (Zone 1 feed, Zone 2 feed, Return, DHW and Mains Cold), externally they've added bonding to the pipe work either side of the metal de-aerater but not the filter, and from what I can tell, this renders the bonding useless?

The other issue that was brought to my attention this morning, when the envelope hit the mat, was that they appear to have done some testing of the circuit that they installed, and the bonding. Without actually testing it to the best of my knowledge. I wonder if anyone would be able to enlighten me as to how this would be possible, or alternatively, possibly linking to an image of the equipment used to test Earth Fault Loop Impedance, RCD operating times and Insulation Resistance.

I won't include any images at the moment, as I should really take their names off of a couple of them before I post them up. But I do believe I will be contacting NICEIC about the work that they have done, and also notifying the Plumbing company of their work.

Any advice, or tips on dealing with something like this would be great.

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,

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

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