Periodic Electrical Inspection & Testing can have many different names:
- Fixed Wire Testing
- Electrical Inspection & Testing
- Electrical Testing
- Electrical Inspection Condition Reporting (EICR)
- Periodic Electrical Testing
- Periodic Inspection Reporting (PIR)
However, regardless of the description used this service involves the inspection & testing of electrical services and systems that conduct, transmit, generate and use electricity throughout a building. It covers all of the fixed wiring within the infrastructure, plus the associated distribution system (Distribution Panels /Boards, Isolators), electrical components including, lighting, switches, sockets and similar accessories, plus fixed electro-mechanical systems and plant.
To understand how frequently you need to inspect and test your installation, you must first establish the following:
- The type and nature of your installation.
- Its use and operations.
- The quality and presence of maintenance regimes.
- External influences having a passive or active effect in the installation.
Many Facilities and Estate Managers will know that a Periodic Inspection is necessary within the workplace, and will have a general understanding that it should be undertaken every 5 years for commercial properties and 3 years for industrial premises.
However, not every business can simply be placed within these two categories, and some buildings may even apply to more than one, so how do you determine the applicable frequency of these inspections?
To make this subject clearer, TEST has created a table displaying the frequency that Duty Holders/ Employers should adhere to when ensuring Periodic Inspections are commissioned in order to remain compliant and ensure the continued health & safety of their employees and those who may come into contact with their electrical system.

1. Particular attention must be taken to comply with S1 2002 No. 2665 Electricity Safety, Quality & Continuity Regulations 2002.
2. The Electricity at Work Regulations 1989 Regulation 4 & HSR25

As already described, some installations may contain a special or specific installation with a shorter formal inspection term. One example of this is hotels which contain swimming pools. The maximum formal inspection term for a hotel in general is 5 Years, whereas the maximum formal inspection term for a Swimming Pools is only 1 Year. This means that the swimming pool should have a full formal inspection & test annually, irrespective of the rest of the hotel’s electrical installation.
