What is fixed wire testing?


Fixed wire electrical testing is a safety procedure aiming to ensure the continued working safety of an electrical installation. All installations such as distribution/fuse boards, power sockets, switches and any hard wired electrical fixtures are at risk of damage and degradation over time. Damage and degradation can cause electrical installations to fail and potentially become dangerous. You may also hear fixed wire testing referred to as; “Hard Wire Testing”, “Electrical Installation Condition Report” (EICR), “Periodical Inspection Report” (PIR), “Fuse Board Testing” or “Fixed Testing”.

Why do you need it?


As stated by the Health & Safety at Work Act 1974 an employer has a ‘duty of care’ to their employees and all personnel on premises they own. Employers must ensure every measure that is reasonably practicable has been taken to ensure safety on their premises. Without maintenance an electrical installation will deteriorate over time which increases the chances of electrical fire, injury and even fatal electrical shocks. “The best way to find out if your electrical installation is safe is to have it inspected and tested by a person who is competent to do so” – Health & Safety Executive.

Frequency of testing?


Employers must do everything reasonably practicable to ensure the safety of their workers, customers and any other personnel on their premises. Decisions are made by the “Duty holder” who will be held liable in the event of a catastrophic electrical failure. Certain installations will need testing at different times, so the frequency can vary. See this article for more information regarding how often you should carry out fixed wire testing. We’re happy to explain the legal aspects and how the Health & Safety Executive affects your business or property specifically over the phone. Contact us here.

How to ensure safety?


Our inspection and tests meet all the requirements of the latest edition of “The Wiring Regulations” also know as “BS7671”. All of our engineers are NICEIC approved (National Inspection Council for Electrical Installation Contracting). The main three things our engineers will carry out:

  • Inspection
  • Test
  • Report

Report Details

EIS test the following areas of an electrical installation; earth continuity, polarity, insulation resistance, earth fault loop impedance, functionality tests of RCDs and operation of overcurrent circuit breakers, isolators and switches. Our engineer’s inspection includes a comprehensive visual inspection of the fixed wiring installation. EIS will produce a report from the engineers findings using industry leading software which organises all visual and testing results. Faults will be clearly marked on page 2 of the report. All faults will have a corresponding priority rating C1, C2 or C3.

These figures refer to the following status:


  • Danger present
  • Risk of injury
  • Immediate remedial action required


  • Potentially dangerous
  • Urgent remedial action required


  • Improvement required.
  • Further investigation required
