Help Understanding EICR

1987FayJane · Feb 5, 2023

I would greatly appreciate if someone could help me understand the following outcomes on an EICR. I am being advised it needs a total rewire but I am a layman.

The wiring is approx 30. Years old. 4 circuits, 2 x lights, one mains (incl kitchen), one for living room.

We will be renovating the ground floor of the property including the kitchen.

Observations

no RCD protection to any circuit (C2)
Damage to electrical wiring accessories (C2)
Burnt connections in the back of kitchen sockets (possible cause of overloading or loose connections) (C2)
immersion heater has been rewired on the same circuit as the sockets - risk of overloading (C2)
no CPC continuity to circuit 2 ring main (F1)
unable to locate water bonding (F1)
no smoke alarms (C3)
no surge protection fitted to consumer unit (C3)

The sections of the report on the EICR as C2 are

4.13
4.17
4.18
5.3
5.5
5.12
5.18
6.1

Thank you

Can you post the whole report here, but remove the name of the company that did the inspection?
There's a best-practise guide from electrical safety first called best practise guide 4 that is worth you acquiring.

Generally wiring from 30 years ago would normally be in serviceable condition. The full report should help us gain a better picture. The reasons for requiring a rewire are usually
a) dangerous wiring that is at end of life or has been damaged. Some of the tests on the report will help determine this
b) not enough points in the right places or not enough circuits to cope with modern demands
c) revonations are happening and it's a good opportunity

Quick thoughts about the other items:

Damage to electrical wiring accessories (C2) Not expensive to replace

Burnt connections in the back of kitchen sockets (possible cause of overloading or loose connections) (C2) If the wiring is serviceable the accessories can be changed.

immersion heater has been rewired on the same circuit as the sockets - risk of overloading (C2) This is a reasonable comment in my view.

no CPC continuity to circuit 2 ring main (F1) This should be a C2, FI would be for if he couldn't complete the test. This needs sorting out.

unable to locate water bonding (F1) The water pipes can be tested to see if it is likely they are bonded.

no smoke alarms (C3) This should be a NOTE as it doesn't relate to electrical safety.

no surge protection fitted to consumer unit (C3) Fair enough

is the property rented out ?

No it is not - it is a house purchase

on the test sheet shows 61008-1 .is in not a rcd .
can you post a pic of the consumer unit .

timhoward · Feb 5, 2023

Hmmm. Well he can't have it both ways - his test results actually portray the fixed wiring as being in excellent condition. (The insulation resistance tests for all circuits are all >200M.). If the overall condition is as bad as he says I'd be very surprised to get those readings. The discrepancy between the overall comments and the test results make me wonder if those tests actually happened or the readings were invented.

I also noticed 4.17 - RCD's required for fault protection. This should not be a C2. Fault protection is covered by other methods on your installation and the tests results show it will work. I worry when I see this as it doesn't build confidence.

Also, he's listed type AC RCD protection for each circuit. This is very confusing.

So far, at a minimum and obviously without seeing it I'd be saying that
-the upstairs socket circuit needs fixing
-some accessories may need changing
-a new circuit should be run for the immersion heater
I'd also be advising a new consumer unit is installed but that doesn't mean what is there isn't safe. It's just that modern units do lots more to protect people from the dangers of electricity.

Additionally the insulation resistance results need confirming (ideally by someone else) as you are relying on them to know whether the opportunity should be seized to get some new cables in. This is really the most important thing. If we believe those results I'd struggle to justify a rewire for safety reasons.

As I already wrote - it might be that your intended use of the property means there are insufficient points and a rewire would be a good idea for other reasons.

Thank you - all advice greatly appreciated. The intended power points are adequate for what we need.
We will be fitting a new kitchen - would that change anything? Apologies I am a complete novice.
Attached the consumer unit (aware this needs replacing as a minimum)

where it shows 101 method ,it should show N/V.Unless he super man .

buzzlightyear · Feb 5, 2023

the white rcd consumer unit what is it marked up.

buzzlightyear · Feb 5, 2023

two boards one test sheet .love this one .

I'm not qualified to comment on the EICR, but I agree with @timhoward, excellent opportunity now (as long as you can afford), to upgrade your existing electrical installation, perhaps not rewiring but upgrading what you have.

i would get a second opinion is good ,has we are key board warriors helping people like you .get your self a spark has soon has poss .

Thank you - in terms of estimated costs (or is it a case of how long is a piece of string) would you expect?
