If my wife were making strides across that floor,the compression forces on the abysmally installed cable routes would ensure the reduced life expectancy of that installation would be greatly reduced still further

If you do intend to leave them in their current residency, at least use metal plate which would have a bit of strength in its construction

Incidentally,I suspect you are technically breaking the law by not carrying out the failed part p procedure to the letter,the builder himself is not responsible for ensuring compliance with that building reg

OK - you're the client, your call if you want to accept it. Given that you've had good advice on here, and that it's the builders problem to keep you happy, I'm suprised you are they guy rushing about putting right the builders obvious lack of knowledge and capability however.

Good luck anyway - I hope it keeps working and gives you many years of trouble free service

Since the size of extensions was increased in April where planning is not required I suspect you may see a bit more of this, dont underestimate builders and the consumer they often know that extending a ring main and lighting circuit into the extension does not invoke Part P.

Are you still in "England" mode or does the planning change include the other countries that make up the UK

I just had some electricians look at it and they said it was acceptable. It will also be checked by another electrician and he will be issuing the certificate.

In the same theme, I think someone has been screwed but is apparently happy

I would not say happy, just trying to make the best of the situation. Got the plumbing to sort out now, but at least I know a good plumber - just need to get him to do the work.

If this is the standard of some of the work that is on view then it makes you wonder what some of the hidden cabling is like..and no..it isnt acceptable the way it is.

Jonbey, you still there?

It is a shame you've had to go through this but I can see where you are coming from in just wanting to get it sorted.

If you are going to buy and install metal capping for this cable then can I suggest that you are careful with the ends of the capping and how they overlap or end. Protect them with care using something robust. Pressure over the years may cause the sharp edges to cut into the cable. We don't usually use it on floors and it is really designed to protect cable from the plasterers trowel.

Looking at the photo of the single cable run across the floor, why cant it be rerouted, if long enough, up and over the 1st floor ceiling joists or a new length put in as it must either be going to another socket or back to board.

Jonbey,

Your latest reactions seem very strange. You have been advised by many industry experts on here that it needs redoing, yet you seem to have accepted a sub-standard installation. I can understand your frustration by it all but this builder cannot be allowed to carry on with doing things in this way. He may of been doing it 20 years, but he has been doing it wrong for 20 years! As for his electrician who just signs it off, words fail me.

Ignoring the long term effects of this abysmal installation, looking at that second photo, there are many things lying about which could damage that soft PVC cable before the floor goes down, they might not be noticeable in the dust but could eventually cause problems, then you will have to have the floor up or find another way of rewiring it.

I'm surprised the independent electrician you had in said it was ok, however he could be just as rough for all we know...You would be better calling in an independent inspector such as one that accesses contractors for schemes such as Napit/NICEIC/ECA.



Now I've written the above, I've just noticed your post was from August so I'm sure the job is finished now, what was the outcome?

A call to an electrician in twenty years time or much sooner if damaged!
