What is an EICR?

An Electrical Installation Condition Report (EICR) is a formal inspection and test of the fixed electrical installation — consumer units, wiring, sockets, lighting circuits and related accessories — against the current edition of BS 7671 (IET Wiring Regulations). It is carried out by a competent person and results in a coded report with observations and recommendations.

An EICR is not the same as PAT testing (portable appliances) or a simple visual check. It focuses on the fixed installation condition and safety.

Who typically needs an EICR?

  • Private landlords (England): electrical safety regulations generally require a satisfactory EICR at least every 5 years and at a change of tenancy in many cases. Scotland, Wales and Northern Ireland have their own frameworks — check local rules.
  • Commercial & multi-let sites: often scheduled on a risk-based frequency (commonly 1–5 years) as part of health & safety and insurance programmes.
  • Homeowners: recommended periodically, especially before sale, after major works, or if the installation is older or modified.

What the report codes mean

C1

Danger present — immediate remedial action required.

C2

Potentially dangerous — urgent remedial action required.

C3

Improvement recommended — not necessarily unsatisfactory alone.

FI

Further investigation required without delay.

An overall outcome of satisfactory or unsatisfactory is recorded. Unsatisfactory outcomes (typically involving C1, C2 or FI) need prompt remedial work and often a re-check so you hold a clear certificate for tenants, agents or insurers.

What happens on the day?

  1. Access arranged to the consumer unit, distribution boards and key circuits.
  2. Visual inspection plus dead and live testing where safe and practical.
  3. Observations coded and discussed where issues are found.
  4. Written EICR issued with circuit details and recommended next inspection date.

Expect some temporary power isolation during testing. For multi-occupancy or commercial sites, plan around business hours and sensitive equipment.
