I need a professional opinion on a recent rewire please

chris140 · Sep 15, 2021

Hi, I have just had a full rewire done on my house by a Napit registered company whom I didn't realise at the time where allowing none registered persons to do the work. I have had to call them back several times to many issues I came across and am now concerned about the safety of the rewire. I have a couple of pictures that they say are not a problem, but I am just not sure!
I would really appreciate it if somebody would have a quick look at the pictures and tell me if they look to be ok?

The first picture is showing the cables twisted around each other under the floor boards (they were also the same in the walls), the other pictures are of six cables going into a dimmer and a double switch that are next to each other, the dimmer is for the bathroom light and the double switch is for the loft light and inline extractor fan in the loft. The final picture is of a dimmer in the kitchen.

Thank you

It looks like several accessories are not earthed correctly or have a CPC (earth) connected to them. I would recommend putting your concerns in writing to the contractor and also send a copy to NAPIT, allow them the chance to rectify any concerns you have.

If they're not forthcoming or carry out the work satisfactorily I would commission and independent electrician to carry out a periodic inspection of their work and raise a report on their findings, then I would contact NAPIT to let them sort it out.

They've taken a lot of short cuts just in those pictures, I'd hate to think what's been hidden away.

Hi, thanks very much for your reply.
He has been back out several times and I am still finding issues.
It's what I can't see as you say, that I'm now concerned about.

Thanks for your advice

I'm not sure what half the pics are trying to show but to me it looks OK from a safety point of view but it's just rough as a badger's.

They grommeted the metal back box and have sleeved the earths, so that's something. It's just that there are some fittings without sheathing going into the box like they should and the second fixing on the wires is shoddy, far too much copper showing.

Don't think this is necessarily inherently dangerous since i've seen a million properties like this but it's just rough. I wouldn't be concerned about your house burning down or anything though.

EDIT: Missed metal not being earthed. That needs to be sorted - if the right fault appears someone could get a belt off that.

Make sure they put RCD protection in at the board.

Thanks for reply but I have not touched anything. I just unscrewed the faceplates to see if I could straighten them because they they are miles out, and then took pictures

That is quite poor work.

Good point.

Could we see a photograph of the consumer unit please? You need not remove the cover.

Hi, thanks for reply.
I think the consumer unit is ok!

Do you have the EIC for the installation work or has the installer not done the testing and certification yet

In what part of Liverpool are you based

Looking at the consumer unit, personally I would have put the upstairs sockets and upstairs lights on different rcds. (Same with ground floor)

That way, if an RCD trips, your not left without any lights in one room… between ceiling lights and plug in lamps.

unless your bedrooms are on the ground floor and living room upstairs

Was there any mention by the electricians of an SPD?

as been mentioned before, lack of earthing to metal accessories, lack of brown sleaving on switched live wires.

bare copper showing at the terminals of accessories.

Lack of attention to detail on such simple things makes me worry about the general standard of workmanship.

and as @westward10 has already mentioned, anyone doing that sort of work for me would find it was the last job they did for me.

If you have any sort payment due to the contractor that did it, i would recommend not paying it until you are happy at the quality of the work.

also, if there is any paperwork such as an installation certificate, post it up for comment (remove any personal details of yourself and the contractor.

Can’t see how it’s been made worse.

I can’t see anything immediately dangerous. It’s rough, poor workmanship, id be ashamed to call it my work, but it’s not immediately dangerous as far as I can see.
metal dimmers not earthed could be classed as potentially dangerous.

non registered sparkies can work for registered sparkies if they are prepared to take responsibility for there workmanship.
