The starting question with eicr diagnostics is always the same: what does the existing installation test at? For Swansea properties we explain each code in plain English and quote remedials at a fixed price so you know exactly what's urgent and what's cosmetic. The paperwork for eicr diagnostics is only useful if it reflects what is actually installed, which is why circuits get identified rather than assumed. On coastal terraces and detached homes in Mumbles and Sketty it is worth ten minutes of anyone's time. Questions asked during the visit get answered during the visit; there is no benefit to either of us in keeping it mysterious. Around SA1–SA7 it is the single most common reason a job runs long. We take a steady number of eicr diagnostics enquiries from Swansea each month, and the pattern is fairly consistent.

  • Commonly, C1 = danger present, fix immediately
  • C2 = potentially dangerous, fix urgently Ask if you want it explained on site.
  • C2 = potentially dangerous, fix urgently shows up more in properties with a long history of small alterations.
  • Damp ingress and age combine, and C3 = improvement recommended (not a fail) is the outcome.
  • FI = further investigation needed. It rarely announces itself until load is applied.

What's different about Swansea

Commonly, 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.

The single most common C2 we see across Swansea is missing RCD protection on socket circuits — usually because coastal salt exposure means outdoor sockets, EV chargers and garden lighting need IP65+ enclosures and stainless fixings to last. Ask if you want it explained on site.

Fixed-price remedials within the week is one of the few things we would ask you to stop using until tested.

Sometimes it is simply the single most common C2 we see across Swansea, and the fix is proportionate to that.

Common questions

What's the most common C2?

Missing RCD protection — usually fixed with a board change.

Can you talk to my letting agent directly?

Yes, if you tell us who to contact. Access and reporting can both go through them.

Does this affect my insurance?

Insurers generally want evidence that the installation has been inspected and any defect addressed. The certification is that evidence.

Can you handle a property that is empty?

Yes. Key access is arranged and the report is sent electronically once the Swansea visit is complete.

Do you cover Swansea for eicr diagnostics?

For coastal terraces and detached homes in Mumbles and Sketty especially — yes — Swansea and the surrounding SA1–SA7 postcodes are part of our regular working area, including Neath and Llanelli, and Swansea Council notification is handled by us where the work requires it.

Will you need to lift floors?

Only if the findings require it, and only with your agreement. We use existing access wherever it exists.

If you have quotes already, send them. We will explain what the differences between them actually mean. We cover Swansea and the SA1–SA7 postcodes, including Neath, for eicr diagnostics. Give us the SA1–SA7 postcode and access details and we will confirm what the visit would cover. We cover Swansea and the SA1–SA7 postcodes, including Llanelli, for eicr diagnostics.
