Failed EICR in Ystrad Mynach: what C1, C2 and C3 actually mean
Got a failed EICR in Ystrad Mynach? Plain-English guide to C1, C2, C3 and FI codes plus fixed-price remedials.
Most people asking about eicr diagnostics in Ystrad Mynach have already had one opinion and want a second that comes with readings. The most useful thing you can tell us on the first call is what changed immediately before you noticed the problem. Neither of us benefits from finding that out halfway through. There is no single right answer for eicr diagnostics — the correct one depends on the age of the installation and how it has been altered since. The paperwork explains it in the same words we would use on site. Here is how eicr diagnostics works at a Ystrad Mynach address, including the parts that decide the price.
- FI = further investigation needed It is part of the standard scope.
- Fixed-price remedials within the week Confirmed before pricing.
- Ystrad Mynach calls of this kind frequently start with C3 = improvement recommended (not a fail).
- Where fittings have been changed over the years, FI = further investigation needed is the usual culprit.
- Fixed-price remedials within the week. We photograph anything we find so you can see it yourself.
What's different about Ystrad Mynach
An "FI" (further investigation) often turns out to be a 30-minute test rather than a major job. We confirm before quoting any remedial work. It is part of the standard scope.
The single most common C2 we see across Ystrad Mynach is missing RCD protection on socket circuits — usually because Ystrad Mynach's mix of valley terraces and newer Hengoed estates means CU upgrades often need both SPD and AFDD to suit older and newer circuits side by side. Confirmed before pricing.
The single most common C2 we see across Ystrad shows up more in properties with a long history of small alterations.
C3 codes are not a fail and don't require — common enough locally that we carry the parts for it.

Common questions
What if I have had this looked at before?
Bring us the previous report if you have one. We test independently but it is useful to see what changed.
What happens if the fault does not show up on the day?
Intermittent faults get logged and monitored rather than declared fixed. We tell you plainly if it has not been reproduced.
How do I know the price will not change?
Because it is set after testing, not before. Extra work is only ever agreed with you first.
Is a specialist needed or will any electrician do?
The work must be done by someone competent and registered. That is what the certification depends on.
