An Electrical Installation Condition Report (EICR) is a formal assessment of the condition of a building’s electrical installation, produced by a qualified inspector against the requirements of BS 7671 (the IET Wiring Regulations). For commercial property owners and landlords in South Wales, an EICR is not optional — it is a legal and insurance requirement, with consequences for both liability and property value if it lapses.
What does an EICR cover?
A commercial EICR assesses:
- The main distribution board and sub-distribution boards
- All wiring circuits from distribution to final circuits
- Protective devices (fuses, MCBs, RCDs, RCBOs)
- Earthing and bonding
- Switches, sockets, and fixed electrical equipment
- Emergency lighting (where present — tested to BS 5266)
- Any sections of wiring that are accessible for visual inspection
The inspector samples final circuits rather than testing every outlet — sampling rates are specified in BS 7671. Observations are categorised as C1, C2, C3 or FI (Further Investigation required).
EICR frequency for commercial properties
BS 7671 Appendix 6 recommends maximum intervals between EICRs depending on premises type:
| Premises type | Recommended interval |
|---|---|
| General commercial premises | 5 years |
| Industrial (clean) | 3 years |
| Industrial (wet, chemical, dusty) | 1 year |
| Healthcare (clinical areas) | 1 year |
| Healthcare (non-clinical) | 3 years |
| Educational buildings | 5 years |
| Agricultural premises | 3 years |
| Caravans and caravan parks | 3 years |
| Swimming pools | 1 year |
For Welsh private rented commercial properties, the Electrical Safety Standards in the Private Rented Sector (Wales) Regulations impose a statutory maximum 5-year interval, with the EICR provided to tenants before the start of a new tenancy. Failure to comply can result in fines of up to £30,000.
Healthcare buildings under NHS Wales estate management typically work to a 3-year interval for all clinical-adjacent buildings, regardless of the 5-year standard recommendation.
Understanding C1 and C2 observations
C1 — Danger present: The installation presents a danger requiring immediate action. The inspector may recommend de-energising the affected circuit until it is remediated. FLD remediates C1 observations on the day of the EICR wherever site access and materials permit.
Common C1 causes: exposed live conductors, missing protection devices, loss of earth continuity on exposed metalwork, overloaded circuits with evidence of thermal damage.
C2 — Potentially dangerous: The installation is not immediately dangerous but remediation is required urgently — typically within 28 days. C2 observations must be rectified before the property can be issued a satisfactory EICR certificate.
Common C2 causes: absence of RCD protection where required under current regulations, non-compliant wiring not meeting current edition requirements, missing or ineffective bonding, non-compliant consumer units without steel enclosures.
C3 — Improvement recommended: The installation does not meet current standards but is not dangerous. C3 observations are documented and costed for future remediation but do not prevent a satisfactory EICR from being issued.
FI — Further investigation: The inspector has identified something that requires further investigation before a conclusion can be reached. FI items are common in older buildings where wiring is concealed or partially inaccessible.
What happens after a C1 or C2 observation?
For a C1 observation, the affected circuit should be isolated until remediation is complete. FLD provides an immediate remediation quotation on the day and will carry out emergency remediation works when the client authorises. Insurance policies often require prompt remediation — an unresolved C1 observation on a property in your portfolio is a liability.
For C2 observations, FLD provides a remediation schedule with costs within 5 working days of the EICR report being issued. We complete C2 remediation works within 28 days as a standard commitment.
Once all C1 and C2 observations are resolved, a full satisfactory EICR certificate can be issued. The certificate is valid for the period specified on the report (typically 3 to 5 years depending on premises type) and should be retained with the property file.
NICEIC Approved Contractor certification
FLD holds NICEIC Approved Contractor status, which means our EICR certificates are backed by NICEIC’s insurance guarantee. For commercial landlords, the NICEIC Approved certification provides assurance that the inspector’s competence has been independently audited. For institutional property portfolios, NICEIC Approved Contractor status is typically a minimum procurement requirement.
NICEIC certificates are registered on the NICEIC database and can be verified by landlords, tenants, insurers and local authorities. Certificates issued by unregistered individuals carry no legal backing and may not satisfy insurance or regulatory requirements.
Welsh landlord obligations
Welsh landlords face a more demanding compliance environment than their English counterparts in several areas:
- Electrical Safety Standards in the Private Rented Sector (Wales) Regulations require EICRs at change of tenancy and maximum 5-year intervals, with certificates provided to tenants
- Welsh Housing Quality Standard 2023 applies to social housing and requires a higher standard of electrical installation compliance
- Buildings containing care home operations are subject to Care Inspectorate Wales requirements that include electrical safety
FLD works with Welsh commercial landlords on portfolio EICR programmes — aggregating multiple properties into a rolling inspection schedule that ensures compliance across the estate without last-minute compliance pressure.
