Fixed Wire Testing

Fixed Wire Testing

What is it?

Fixed wire testing, also known as EICR (Electrical Installation Condition Report) or Hard Wire Testing, involves assessing all the permanent electrical wiring in your premises. This includes:

  • Fuse boards

  • Conduits

  • Cabling

  • Sockets and switches


These components are susceptible to damage over time due to wear and tear, making regular testing essential for safety and compliance.

Why do we need it?

Ensuring the safety of your electrical installations is not only a legal requirement but also vital for preventing accidents such as fires or electric shocks.


Key legal frameworks include:

  • Health & Safety at Work Act 1974: Employers must protect the safety and welfare of employees, visitors, and contractors.

  • Electricity at Work Regulations 1989: Requires electrical systems to be maintained to prevent danger.


The 18th Edition Wiring Regulations (BS7671:2018) set the latest standards for the safe installation and maintenance of electrical systems. Failure to comply can result in legal action, increased insurance premiums, or claims being invalidated.


Compliance with these laws demonstrates due diligence and ensures a safer workplace.

When should we do it?

Testing frequency depends on the type of premises:

Installation Type

Maximum Testing Interval

Offices, schools, shops, restaurants, hotels

Every 5 years

Industrial locations, leisure complexes, theatres

Every 3 years

Caravan parks, marinas, swimming pools, launderettes

Every 1 year

How do we do it?

At Office Compliance Management, we follow a rigorous three-step process:

  1. Inspection

    • A comprehensive visual assessment of your fixed electrical wiring system.

  2. Testing

    • Includes key checks such as:

      • Earth continuity

      • Insulation resistance

      • Polarity

      • Earth fault loop impedance

      • Functional tests of RCDs, circuit breakers, isolators, and switches

  3. Report

    • A detailed report created using industry-leading software includes:

      • Installation details

      • Test schedules

      • Observations on the condition of the installation

      • Test results


Each issue is categorised with a priority code:

  • C1: Immediate danger—remedial action required.

  • C2: Potential danger—urgent action required.

  • C3: Improvement recommended.

  • FI: Further investigation required.


A quotation for any required remedial work will accompany the report, ensuring you can address issues promptly.
