What Is an EICR? A Guide for Commercial Buildings

An Electrical Installation Condition Report (EICR) is a formal inspection of a building's fixed electrical installation. It assesses the condition of the wiring and connected components, identifies any defects or potential safety risks, and confirms whether the installation remains safe for continued use.

Unlike routine maintenance or reactive repairs, an EICR provides a structured, point-in-time assessment of a commercial property's fixed electrical installation. This includes components such as distribution boards, wiring, sockets, switches and other fixed electrical equipment that form part of the building's installation.

An EICR is a specific, certified inspection with a defined scope and a formal report at the end of it, distinct from the ongoing planned maintenance and testing that takes place between inspections.

Electrical systems naturally deteriorate over time through normal use, environmental conditions and changes to the way a building operates. Without regular inspection, faults can develop that increase the risk of electrical failure, disruption or safety incidents.

An EICR helps identify issues before they become more serious, allowing organisations to plan remedial work and maintain safe electrical systems. Regular inspections can also help businesses:

• Demonstrate compliance with relevant electrical safety standards
• Reduce the risk of unexpected electrical failures
• Protect employees, visitors and contractors
• Support planned maintenance programmes
• Maintain accurate records of the condition of electrical installations

During an EICR, a qualified electrician carries out a detailed inspection and testing programme to assess the condition of the electrical installation. This typically includes:

• Distribution boards and protective devices
• Fixed wiring and electrical circuits
• Earthing and bonding arrangements
• Socket outlets and switches
• Signs of wear, damage or deterioration
• Electrical testing to verify system performance

Once complete, a report is produced detailing the findings and identifying any observations that require attention. Where issues are identified, they are classified according to their severity, helping businesses understand which items require immediate action and which should be addressed as part of planned maintenance.

The recommended inspection frequency depends on the type of premises, how the building is used and the level of risk associated with the electrical installation.

Many commercial buildings require a periodic EICR every five years, although higher-risk environments such as industrial facilities, healthcare settings and certain public buildings may require inspections more frequently.

Changes to the building, significant alterations or evidence of electrical faults may also mean an inspection is needed sooner. A competent electrical contractor can advise on an appropriate inspection programme based on the building and its intended use.

It is not unusual for an EICR to identify observations that require attention, particularly within older buildings or installations that have been modified over time.

The report will categorise any defects according to their level of risk, helping businesses prioritise remedial work where necessary. Addressing these issues promptly helps ensure electrical systems remain safe, compliant and capable of supporting the ongoing operation of the building.

An EICR is one part of managing electrical infrastructure across the life of a commercial building.
