Periodic inspection Report

Electrical installations can deteriorate with age and use. It is recommended that electrical installations are inspected and tested periodically as appropriate to their use and environment to verify compliance with the National Rules for Electrical Installations – ET101.

Please be mindful that a Periodic Inspection Report (PIR) is a report and not a Completion Certificate. A PIR is intended to identify the condition of an electrical installation, be it good or bad.

We are a Registered Electrical Contractors (RECs) and we carry out periodic inspection and testing in line with the National Rules for Electrical Installations.

We provide a copy of the PIR accompanied with the completed Test Record Sheet to their customer and explain the next steps required of the customer to bring the installation in line with the relevant standards. We also give the customer a quote for any repairs that need to be carried out.

Completing a Periodic Inspection Report:
The comments/remedial work section shall outline any breach identified and give a recommendation to resolve the breach.

Following the periodic inspection and testing of an installation, a schedule of the following shall be compiled:

  1. All defects, damage, deterioration of equipment or wiring, and the potential hazards from any non-compliance with the National Rules for Electrical Installations.

  2. Recommendations for necessary consequential remedial works.

 

The REC shall use the numbering system (1-4 below) to indicate to the person(s) responsible for the electrical installation the recommended action to be taken.

  1. Requires urgent attention.

  2. Requires improvement.

  3. Requires some attention.

  4. Does not comply with the current National Rules for Electrical Installations*.

 

* A non-compliance with the current National Rules for Electrical Installations does not necessarily imply that the installation inspected is unsafe.

We shall issue the original white copy of the PIR and of the Test Record Sheet to the person responsible for the electrical installation.

Serious defects
Where a REC identifies serious defects in an electrical installation, a Notice of Potential Hazard (NoHz) should also be issued to the person responsible for the electrical installation. 

A periodic inspection will:

  • Reveal if any of your electrical circuits or equipment are overloaded.

  • Find any potential electric shock risks and fire hazards.

  • Identify any defective electrical work.

  • Highlight any lack of earthing or bonding.

  • Compliance with the National Rules for Electrical Installations ET101.

Tests are also carried out on wiring and fixed electrical equipment to check that they are safe. A schedule of circuits is also provided, which is invaluable for a property.

 


How often is a periodic inspection required?

Your electrics should be inspected and tested every:

  • Commercial Premises 5 years

  • Offices/ Retail 5 years

  • Leisure Complexes 3 years

  • Residential 5 years

  • Industrial 3 years

Other times when a periodic inspection should be carried out are:

  • When a property is being prepared for letting.

  • Before selling a property or buying a previously-occupied property.

 

 

Who should carry out the periodic inspection and what happens?

Periodic inspection and testing should be carried out only by a Registered Electrical Contractor (REC)


The inspection takes into account all the relevant circumstances and checks on:

  • The adequacy of earthing and bonding.

  • The suitability of the switchgear and controlgear. For example, an old fusebox with a wooden back, cast-iron switches, or a mixture of both will need replacing.

  • The serviceability of switches, sockets and lighting fittings. Items that  may need replacing include: older round-pin sockets, round light switches, cables with fabric coating hanging from ceiling roses to light fittings, black switches and sockets mounted in skirting boards.

  • The type of wiring system and its condition. For example, cables coated in black rubber were phased out in the 1960s. Likewise cables coated in lead or fabric are even older and may well need replacing (modern cables use longer-lasting pvc insulation).

  • Sockets that may be used to supply portable electrical equipment for use outdoors, making sure they are protected by a suitable residual current device (RCD).

  • The presence of adequate identification and notices.

  • The extent of any wear and tear, damage or other deterioration.

  • Any changes in the use of the premises that have led to, or may lead to, unsafe conditions.

We will then issue the report along with the test results detailing any observed damage, deterioration, defects, dangerous conditions and any non-compliance's. 

If anything dangerous or potentially dangerous is found, we will list it as part of the remedial action that needs to be carried out with a rating of 1 to 4 as to how serious the defect is and what action is required to rectify it.

An installation could vary from a standard small 230 Volt single phase electrical wiring system with distribution boards, lighting and general services to, in certain instances, arrangements involving three-phase high-voltage switch-gear, transformers and associated parts of the electrical installation in a major industrial or commercial environment.

Types of Inspection and Testing to be done during formal Inspection & Testing.

The following non-exhaustive list indicates the types of inspection and tests that are necessary to complete the periodic inspection and testing of an installation.

  • General appraisal of the installation by a competent person to assess the physical condition of the installation and its suitability for its environment.

  • Continuity of the protective conductors and of the main supplementary equipotential bonding.

  • Continuity of conductors in ring final circuits.

  • Resistance of protective conductor.

  • Insulation resistance of the electrical installation.

  • Polarity.

  • Fault Loop Impedance test.

  • Verification of Operation of RCDs including the tripping times of all RCDs.
