Why Did It Stop Being Called PAT Testing?
What Is PAT Testing Called Now?
PAT testing is now more accurately referred to as “In-Service Inspection and Testing of Electrical Equipment.”
The name change reflects updated guidance to ensure all electrical equipment is inspected and tested properly, rather than only focusing on portable items.
Quick Answer: PAT Testing Name Change
“PAT Testing” is still commonly used in the industry
The official term is now In-Service Inspection and Testing
The change comes from the 5th Edition Code of Practice
It helps ensure no electrical equipment is overlooked
Focus has shifted to duty holder responsibility and safety compliance
Why Did PAT Testing Change Its Name?
The term “Portable Appliance Testing” was considered misleading because:

Fixed or less mobile equipment was sometimes ignored
Important safety checks were missed in some environments
The updated terminology ensures that:
All in-service electrical equipment is considered
Responsibility is clearly placed on the duty holder
Electrical safety standards are consistently applied

What Changed in the 5th Edition Code of Practice?
