Query on recent Electrical Certification for property

[Julie.]

He has failed to mention the very high r2 for the ring final.
It should also be noted BS7671 does not give minimum values of insulation resistance values for an EICR so 2.1 Meg ohm may not even warrant a mention.

He does it's squirreled away in item 2 - Zs is to (sic) high

Thank you all so much for your input. Much appreciated.

5 - at 1x 300ms is acceptable, and at 5x 40ms is OK- the rcd appears to meet the standard.

Where is that time stated on the report?

EDIT: It's okay I see it now.

This is the relevant part of the wiring regs isn't it?

Huh, link won't post.



So the test results show 54ms at 1x and 23ms at 5x, which as you say are both well within the 300ms (1x) and 40ms (5x) in BS7671.

Thanks

Yes, exactly as you found.

Although actually since amendment 2 there is actually no requirement to do these tests as we used to, but it passes in any case

The test was done 10/08/2021 according to the report, so pre-Amendment 2 (28/03/2022). Although the date doesn't really make sense either because the invoice for the work wasn't charged to the owner until Feb 2022, unless maybe the work was postponed due to lockdown following the initial test?? The reason we're looking at it now is because it's very much only the tip of a larger iceberg.

Since amendment 2 we only have to carry out the RCD test on 1/2x and 1x. 5x is no longer a requirement

I would question the things that have been mentioned to be only a C3.

The thing that’s probably going to cost you the most is the the fault finding

A relative recently had an electrical certification done on a rented property. The property was build in 2005 and had previously passed 3 electrical certifications with flying colours, however this time round a number of issues arose resulting in a bill of £500, which was very surprising. Several issues, such as RCDs I can trace back to the 2018 changes to the wiring regs, however there was mention of wires terminated incorrectly and needing glanding, which seems strange given that they passed 5 years ago, unless all the previous 3 were wrong. Additionally the cooker was on a 32A circuit breaker, and the engineer said it needed a 40A breaker?? There has been no problems with the 32A breaker tripping, so why was it necessary to increase it to 40A?

I had other issues with plumbing work done by the same outfit following the installation of an electrical shower (it leaked and then leaked after he allegedly fixed the leak). Could you help explain the changes?

need to pass this report onto the property owner he/ she is the one res[onsibl

Bit picky I’d suppose but thinking this is wrong too.
Personally the details here would only be the Main Switch, I would put the RCD on the schedule results page.
I take it’s a Split DB configuration

The work has already been done. The guy has been doing all fixes, electrics and plumbing on the property, which is managed through an estate agent. Basically, they chose the contractors. Since Feb 2022 the charges for repairs amounted to £1400(!) on an 18 year-old property, not including EPC and gas certificate. The owner is changing estate agent as a result, but the estate agent defends the contractor to the end and is convinced there isn't a problem and is charging a large fee for the transferral of management. The owner's position, and mine, is that the estate agent has 'substantially failed in their duties' by not finding out last year (when it was first queried) what I found out in a single day, and also not seeing the general problem with the quantity of repair bills on a relatively new property as well as the faulty shower work.

Our main concern now is whether the work he's done is up to scratch, or is that faulty too?

2 - this aligns with the test report figures, so firstly it looks most likely that a socket outlet has been changed, or whatever and the earth connections haven't been made correctly, this would be a valid unsatisfactory on the report, secondly the low IR reading is difficult to understand, he gives a value of 2.1 somethings! If those somethings are Meg ohm then actually it's technically a pass. If they are k ohms, that's a genuine issue, wouldn't trip the rcd, but is a valid C2, if ohms (which he implies), the rcd would trip all the time.

Okay thanks.
