When does a domestic property need a rewire ???

[Dozer 73]

see a lot of different threads on here , where people asking for advice on old installations , one tonight even about moving sockets installed in the70’s in metal conduit and 2 core cable
It’s a funny game where not every one thinks the same , know wiring lasts a long time but the accessories get worn , make bad connections to plugs , lamps , switches etc
Personally I’m quite quick to advice a rewire , not for my personal gain tbh
Just wanted to know at what point other people advice a rewire

What test results will justify a rewire.

That's a good point. Most poor results whether they are IR results, continuity etc result in fault finding as they are generally only on one or 2 circuits. I guess if there were poor results on all circuits then you could justify a rewire. I rarely advise a rewire or indeed a CU change, unless the conditions are as in Lee's post above.

I am absolutely for if it aint broke don't fix it. I take something of a pride in fixing older systems so that they pass tests and meet regs. However as @Leesparkykent says when the cost of fixing is near to the cost of re-wire I quote for both and usually the customer will see the sense in having a re-wire.

Usually if its old rubber cable which has deteriorated or lots of the dreaded green goo in PVC cable.Or sometimes just a partial rewire if its a mixture of cables. If there is mice damage which I find a lot I would go for a consumer unit replacement after repair if its got no RCDs so it has some protection. Got one to look at on Frid, the customer shoved a Brillo pad down a mouse hole and it went bang and ignited ( the pad not the mouse.)

Hang on......don't give 'em more reason for upping the 18th......isolate before inspection of mouse holes....

Personally I am not a fan of the" cause it's old, it's dangerous club ".
This smacks of taking advantage of customers insecurities.
I have seen plenty of old instalations that were installed to a very good stantard.
Therefore they are still working well today. It comes down to the results of talking with the customer ( what are their concerns ), the results of a visual inspection, What current safety standards reccomend, and the results of some good old fashioned testing.

A substantial proportion of the board changes I do are on installations with imperial stranded pvc cables. As has already been stated provided it hasn't been subjected to DIY or kitchen fitters it's usually fine for continued service.
Another point for home buyers to be aware of is that a 'rewire' isn't always a rewire. It's surprising how often a few repairs and upgrades to an old installation suddenly becomes...'it's all been rewired' when the house is up for sale.

Just because the test results are fine, and inspection of a sample of accessories suggest the same, doesn't reveal the condition of cabling etc under floors. Manufacturers typically guarantee their cables 20-30 years, subtract the abuse handed out by diy'ers, pretty much lines up 1970's properties for a rewire. I know in reality, most would opt for a shiny new CU, utilising manky old imperial cables, but I wouldn't. But then its easy for me to say being a sparks, but not so for others.

If I moved into an older property, where the central heating was upgraded, with new bathroom & kitchen, I'd consider putting aside some money to upgrade the electrics. Which is exactly what I advised my customer, the other week, with no cpc's in the lighting circuits. I don't do EICR's, but that's my personnel opinion.

When the property has been owned by a builder for ten years .....

Been to a couple of those patchwork bodge ups lately ...

The job I've just finished, one socket circuit on a 4mm radial for the whole house, tested fine but only 4 double sockets on it! One in living room, two in kitchen and one in a bedroom. Two bedrooms with no socket outlets at all. One lighting circuit, basic as it comes, lots of darkness in that house. I suppose it was a rewire, but felt more like doing a new build! Not a lot to rip out, but a lot of new stuff going in, should have seen the old dears face when she could actually plug stuff in wherever she liked and could ditch the extension leads for good, she was like a little kid on Christmas morning!

I'd have to disagree on the point about 1970's cables being past it. In my experience properly installed quality PVC cables are good for a great deal longer than 20-30 years. Other things excepted, I would not advise a rewire purely on the age of PVC cables.

Well I have to disagree with you. I predate 1970's, and her indoors thinks I'm well past it. In fact she reckons I've only got twenty years left

Agreed pvc copper has a very long life , new dB with rcd massive improvement for shock/fire protection , wired smoke alarms yet another improvement
I wonder why all local councils don’t just do upgrades instead of doing full rewires when not really needed , with massive costs of plastering , decorating vouchers , big overheads of contractors ?

When I did my house bashing stint many years ago, I often wondered why is this coming out? I sometimes think we ripped out a better installation than the one we put in! And the damage created to rewire a house in a day was unreal....I used to hate it!

Never mind what the painted one thinks, I predate 1970's and I bloody know I'm well past it, I don't need her reminding me

I assumed everybody knew,a full rewire is needed,somewhere between,the Fire Brigade leaving,and the plasterer arriving...tell me i'm wrong?
