Understanding EICR's: What Every UK Business Needs to Know

What is an EICR?

An Electrical Installation Condition Report (EICR) is a formal document produced following an assessment of the electrical installations within a building. It determines whether the systems are safe, compliant, and fit for continued use. Think of it as a health check for your electrical infrastructure.

Why is EICR Important for Businesses?

In the UK, businesses have a legal duty of care under the Electricity at Work Regulations 1989 to ensure electrical systems are safe and properly maintained. An EICR helps you demonstrate compliance and mitigate risk.

Neglecting to carry out regular inspections can lead to:

  • Increased risk of fire and electric shock

  • Legal liability in the event of an incident

  • Voided insurance policies

  • Fines and potential business closure

How Often Should EICRs Be Done?

The recommended frequency varies by premises type:

  • Commercial Offices – every 5 years

  • Industrial Sites – every 3 years

  • Rented Properties – every 5 years or at the start of a new tenancy

  • Public Buildings (e.g. schools) – every 5 years (or more frequently depending on usage)

However, factors such as environmental conditions, equipment use, or age of installation may require more frequent inspections.

What Happens During an EICR?

A qualified electrician will:

  • Visually inspect the installation for damage or defects

  • Carry out dead testing and live testing to assess insulation, polarity, and earth loop impedance

  • Identify any issues and classify them as:

    • C1 (Danger Present) – Immediate action required

    • C2 (Potentially Dangerous) – Urgent remedial action needed

    • C3 (Improvement Recommended) – Not unsafe, but non-compliant

What Should a Business Do After Receiving the EICR?

  • Address any C1 or C2 faults immediately with a certified contractor

  • Log and store the report for audit and insurance purposes

  • Schedule the next inspection in line with recommendations

Final Thoughts

Investing in an EICR isn’t just about staying on the right side of the law. It’s about protecting your employees, your customers, and your business continuity. Proactive testing is always cheaper—and safer—than dealing with the aftermath of a preventable incident.
