Failed EICR in Aberdare: what C1, C2 and C3 actually mean
Got a failed EICR in Aberdare? Plain-English guide to C1, C2, C3 and FI codes plus fixed-price remedials.
A short guide to eicr diagnostics for Aberdare property, written by the person who would do the work. Whether the property is owner-occupied or let in Aberdare, the technical work is identical — only the paperwork's recipient changes. That detail is what a proper survey is for. A written record matters as much as the work. Anything we find at a CF44 address is documented in a form you can hand to someone else. That is one reason our price does not move after the survey. Owners and landlords across CF44 ask about this in roughly equal numbers, for slightly different reasons.
- C2 = potentially dangerous, fix urgently We will confirm it in writing.
- C3 = improvement recommended (not a fail) It affects sequence more than cost.
- Fixed-price remedials within the week. The symptom is the same whichever cause is behind it, so we measure.
- The single most common C2 we see across Aberdare. That is the finding, not the diagnosis.
- C3 codes are not a fail and don't require — the finding that most often explains the symptom you described.
What's different about Aberdare
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. We will confirm it in writing.
The single most common C2 we see across Aberdare is missing RCD protection on socket circuits — usually because older Aberdare cottages frequently lack RCD protection on any circuit, meaning a consumer unit upgrade is almost always the first remedial after an EICR. It affects sequence more than cost.
An "FI" (further investigation) often turns out to be. The remedy depends on what the readings say, not on the symptom alone.
C1 = danger present, fix immediately — identified by comparing readings circuit by circuit.

Common questions
Is the work guaranteed?
Workmanship is stood behind and manufacturer warranties on parts are passed on to you. We do not offer guarantees we cannot honour.
Do I need to be there for the whole visit?
Only for access and for the walk-through at the end. Most owners in Aberdare leave us to it once circuits are identified.
Is older wiring automatically a problem?
No. Plenty of older Aberdare installations test well. Age is a reason to check, not a verdict.
What is not included?
Building work, decoration and anything outside the electrical scope. Those are flagged rather than absorbed.
Do you cover Aberdare for eicr diagnostics?
The relevant point here: yes — Aberdare and the surrounding CF44 postcodes are part of our regular working area, including Merthyr Tydfil and Mountain Ash, and Rhondda Cynon Taf County Borough Council notification is handled by us where the work requires it.
Will you show me what you found?
Always. C3 codes are not a fail and don't require is easier to understand when you can see it, so we photograph anything hidden.
Tell us what document you have been asked for and by whom, and we will confirm exactly which one applies. We cover Aberdare and the CF44 postcodes, including Merthyr Tydfil, for eicr diagnostics.
