EICR Failed in London? What to Do Next (Same-Week Remedial Plan)

Only if they performed the original installation work and the C1 or C2 finding is traceable to defective workmanship within the warranty period — typically 6 years for negligence claims. Where the contractor only performed the inspection, their role ends at the certificate. NICEIC, NAPIT and ELECSA hold their members to a complaints process you can invoke if you believe the coding was incompetent.

Commission an independent second-opinion review from a different NICEIC contractor. The reviewing inspector examines the original certificate, conducts a focused on-site verification of the disputed codes, and issues a written opinion. If the second opinion overturns a C2 down to a C3 — we see this in roughly one in five disputed reports — you can challenge the original through the issuing contractor's certification body.

Booked as a half-day verification, billed at £125. The reviewing inspector reads the original EICR before attending, focuses testing on the disputed circuits, and either confirms the original codes or issues a fresh EICR with the corrected codes. The new certificate, where issued, becomes your certificate of record.

Yes for buy-to-let remortgages on most major lenders (Nationwide, Lloyds, Santander, NatWest, Barclays among others typically require a satisfactory EICR within the last 5 years). It does not affect an existing mortgage already drawn down. Remediate within the 28-day window, secure the Minor Works or re-inspection certificate, and the mortgage application proceeds.

A Section 21 notice for unrelated grounds is not automatically invalidated by an unsatisfactory EICR, but it is paused if the EICR has not been supplied to the tenant within the 28-day statutory window. Section 8 notices for rent arrears or breach of tenancy remain valid. Practical answer: complete remediation first, then any eviction proceeds on cleaner footing.

Document why. If access is delayed by the tenant, keep written evidence (letter requests, calendar invites). If parts are on extended lead-time (specialist consumer units, three-phase RCDs) keep the supplier order confirmation. Local authorities will accept evidence of best efforts where the breach is demonstrably outside the landlord's control — but undocumented delay is a £30,000 penalty risk.

Only when (1) a tenant complains, (2) the property is HMO-licensed or selectively-licensed and the licence requires EICR submission, or (3) the local authority is conducting a proactive inspection. Most remedial work completes inside the 28-day window without council contact. Where the council does request the EICR, they're entitled to it within 7 days.

Possibly at renewal. Major landlord insurers ask whether a current satisfactory EICR is on file. An unremedied unsatisfactory EICR on the day of a claim could be cited as a material non-disclosure if the claim relates to an electrical fault. Once remediated and recertified, the slate is clean — insurers accept the Minor Works or new EICR as evidence of compliance.

A void is the cleanest time to remediate. No access constraints, no tenant disruption notice required, and the new tenancy starts with a fresh satisfactory EICR. Where a remedial window straddles a tenancy change, the incoming tenant must be given the EICR and the remedial confirmation pack before they move in.

Minor Works certificate is sufficient where one or two circuits were remediated and the consumer unit was untouched. A full new EICR is the cleaner audit trail where the consumer unit was replaced, three or more circuits were touched, or you are mid-mortgage application. We advise per case — the cheaper option is sometimes the wrong one for the audit trail.
