Fixed Electrical Testing Explained
What is Fixed Electrical Testing?
Fixed electrical testing is the structured inspection and testing of a building’s permanent electrical installation to confirm that it is safe, compliant, and functioning as intended under the legal requirements of both the UK and Ireland. In the UK, this work supports compliance with the Electricity at Work Regulations 1989, while in Ireland it aligns with employer duties under the Safety, Health and Welfare at Work Act 2005 and associated regulations.
Often delivered through an Electrical Installation Condition Report (EICR), fixed electrical testing assesses the condition of wiring, circuits, distribution boards, protective devices, and other fixed components to identify defects, deterioration, or non‑compliances that could lead to electric shock, fire, or equipment failure. This process—commonly known as fixed wire testing, electrical inspection and testing, or an electrical safety inspection—helps ensure that installations remain safe over time and meet the relevant national standards.
By verifying the integrity of the electrical system and highlighting any issues that require remedial work, fixed electrical testing plays a central role in maintaining electrical safety, reducing risk, and protecting people, property, and business continuity.

Know Your Obligations
When Do You Need Fixed Electrical Testing?
Fixed electrical testing is required at key points to ensure your installation remains safe, compliant, and properly maintained. The points below reflect the expectations of both Irish and UK legislation, as well as the recommended testing intervals set out in the Wiring Regulations. A shorter inspection cycle may be needed in higher‑risk environments, and you must be able to demonstrate when your system was last formally inspected if an electrical incident occurs.
-
At the recommended intervals — Commercial properties are typically tested every 5 years, while industrial premises usually require testing every 3 years, depending on risk and operating conditions.
-
After an electrical incident — Any shock, fire, overheating, or unexplained tripping event requires immediate inspection to confirm the system is still safe.
-
Following major electrical work — New circuits, distribution board upgrades, or significant alterations trigger the need for updated inspection and testing.
-
When a building changes ownership or occupancy — Fresh EICR checks provide assurance that the installation is safe for new tenants, owners, or business operators.
-
In harsh or demanding environments — Areas exposed to moisture, dust, vibration, chemicals, or heavy electrical loading often require more frequent testing.
-
When signs of deterioration appear — Burning smells, damaged cables, discoloured outlets, or repeated breaker trips indicate the need for urgent inspection.
-
When required by insurers or regulatory bodies — Many insurers and industry regulators mandate periodic electrical inspections as part of compliance and risk management.
