Explain EICR findings to a customer in plain English
C1, C2, C3 and FI mean nothing to most homeowners and landlords. A clear explanation gets remedial work approved faster and avoids "you're just upselling".
Steps
- Finish and sign the EICR as normal. AI plays no part in the inspection or the coding.
- Copy the observations and codes you gave, without the property address or client name.
- Check which edition your report form is on and copy the FI wording printed in Section K of that form into the prompt. On a BS 7671:2018+A4:2026 form (Amendment 4) it reads "further investigation is advised"; on an earlier form (Amendment 3) it reads "further investigation required without delay". Go by the edition printed on your form. If you use the NICEIC Online Certification System, NICEIC says form reference 18.4 is an Amendment 4 form (declaration "BS 7671 2026") and 18.3 an Amendment 3 form (declaration "BS 7671 2024"); other schemes and software may label their forms differently.
- Paste the prompt below with your observations and remedial prices.
- Check every explanation matches what you found. Delete anything that overstates or understates the risk.
- Send it alongside the official report, never instead of it.
The exact prompt
I'm a [UK] electrician. Turn my EICR observations into a plain-English summary for a [homeowner / landlord]. For each observation: the code I gave, what that code means in one sentence, and the remedial work with my price. Use these meanings: C1 danger present, C2 potentially dangerous, C3 improvement recommended, FI [paste the exact wording printed on my report form: "further investigation is advised" on a BS 7671:2018+A4:2026 form, or "further investigation required without delay" on an earlier form]. Use ONLY my observations, codes and prices. Don't change or add any code, and don't add safety advice of your own. Finish with: overall result [SATISFACTORY / UNSATISFACTORY] exactly as on my report (do not work it out from the codes, and do not say whether a C3 or FI changes it), and next steps: [e.g. book remedial work; we'll confirm in writing once done]. Under 250 words. Observations, codes and prices: [paste]
✓ Check before you send
- Every code is exactly as on your signed report.
- Nothing reads as scaremongering, or as playing down a C1 or C2.
- Prices match your quote, and VAT is shown correctly.
- The FI wording and the overall result match the edition of the form you signed. On an Amendment 4 form only C1 and C2 make the result unsatisfactory; on an Amendment 3 form an FI did too.
UK notes extra
- Private landlords in England must have the electrics inspected and tested at least every five years (or by an earlier date the report gives) and, where the report requires further investigative or remedial work, have it done within 28 days (or any shorter period the report states). GOV.UK: electrical safety standards in the private and social rented sectors (England).
- Plain-English safety guidance you can point customers to: Electrical Safety First.
- From 15 October 2026 EICRs are to be issued to BS 7671:2018+A4:2026. On an Amendment 4 form, FI reads "further investigation is advised" and, like C3, does not make the overall result unsatisfactory; only C1 and C2 do. On earlier forms an FI also made the report unsatisfactory. When checked on 15 October 2026, the GOV.UK landlord guidance had not been updated and still describes FI as "required without delay", so do not tell a landlord that an FI can be ignored: tell them to ask the inspector what is needed and to check the current guidance.
