Any idea what a periodic inspection will costs ?

[freestyle]

Good Afternoon

I am interested (mainly because I am replacing my central hearing) in getting my flat rewired.

Couple of questions

1) Any idea what a Periodic inspection costs ?
http://www.niceic.org.uk/consumers/pir.html
1a) Is it worthwhile ?

2) Any idea what I can expect it would cost to re-wire the flat ?
2a) To save money could I run the cables ? And simply get the electrical guy in to connect and test ?

3) Is it even worth re-wiring at all ?
The cable type I currently have are grey PCV. The wire inside consists of 3 strands for each colour (black and red) and the earth is a single thin cable..........

To establish the condition, and decide what rectivications (or rewire) is required, a PIR should be done.

For a small flat, you should expect approx £70, and a couple hours work.

Prices vary hugely from one end of the country to the other, and there is an even bigger difference in the middle! This is a ball park figure. Many sparks may take a look and say it will take longer/cost more depending on many variables.

Why does new CH lead to a rewire?

If you're concerned about the state of your wiring

Possibly - but you'd need to do that with his agreement, direction and cooperation, as if he is certifying the installation he's going to want to be sure you've installed the cables properly. If you're adding/moving accessories you can certainly do all the chasing and sinking, and you will not upset him one bit if you do all the furniture moving, carpet & floor lifting etc.

3) Is it even worth re-wiring at all ?

That's a generic description of twin & earth that doesn't really help much. Do you know how old it is? Are the red & black cores solid or stranded? Do you have fuses or MCBs? Does your lighting circuit have an earth?


Freestyle - if your new plumbing is going to be in copper, not Hep2O, then use, or have your plumber use, fittings from these people:

http://www.earthcrimp.co.uk/earth_crimp_connector_range.html

where you'll need supplementary equipotential bonding, as that will mean you won't need earth clamps and you will thus be able to keep all of the bonding connections under the floor.

Might be worth having your plumber and electrician speak to each other about the requirements....

Thanks for the replies.

You quoted me when I explained that the cables are stranded ?? Is there anything else I should have said

3) Is it even worth re-wiring at all ?

So I was trying to anticipate your question. Does this help with identifying the cables age ?

Also sorry about asking for costs. I do realise that prices across the country vary, and will review the rules again.

Based on reading the rules it seems its ok to ask for a local referal. So if anyone does know of an individual or company who would work in EN5 please let me know.



In reply to "Why does installing Central Heating suggest a re-wire" quite simply I am lifting all the floor boards, replacing carpet with lamite etc. So I don't want to have to pull all this up again in a few years time

My apologies - didn't read that properly - thought you were saying 3 cores...

Are all your cables 3-strands? That makes them very small - what rating are the fuses on the circuits?

Not 7-strands for sockets?

1960-1975 ish used tinned (silver coloured) cables, a core would have 3 strands. It is the imperial equiv of 2.5 usually. More strands for 4mm equiv.

It is old, but my house is the same . Insualtion fine, and earth too at mine.

Well my house was built in 1965 ish..

But I am getting back to the question. Now that we have kind of sorted out what cable I have.. Does it mean this place has never been re-wired !

I'm too young to know what to look for..

Although I will be phoning some elecy's tommorow from the NSICC website.. or whatever its called
