Who is it for ?

Health and safety regulation requires that every type of electrical installation, on every business premise should be annually inspected as it must comply with all the electrical regulations.


All electrical installations deteriorate with age and use. They should therefore be inspected and tested at regular intervals to check whether they are in a satisfactory condition for continued use. Such safety checks are commonly referred to as ‘periodic inspection and testing.

A regular visual inspection should be carried out on all electrical installations. A visual inspection should look for:

  • Breakages
  • Wear & deterioration
  • Signs of over heating
  • Missing parts (covers, screws)
  • Switch gear accessibility
  • Residual current devices test

Time Intervals between Periodic Inspections

The time between periodic inspection and testing of installations should be based on a risk assessment with the intervals dependent on a number of parameters such as the:

• age of the installation,

• quality of the installation,

• environmental circumstances,

• type of persons using the installation,

• amount of supervision of the person responsible for the installation,

• guidance of the manufacturer,

• possibility of damage to the equipment.

No 299 of 2007) as amended by the Safety, Health and Welfare at Work (General Application)(Amendment) Regulations 2007 (S.I. No. 732 of 2007) ), which states that

What is a periodic inspection?

A periodic inspection is an inspection and associated testing to check whether an electrical installation is in a satisfactory condition for continued service. On completion of the necessary inspection and testing, an Electrical Installation Condition Report will be issued detailing any observed damage, deterioration, defects, dangerous conditions and any non-compliance with the present-day safety standard which might give rise to danger.

Who should carry out a periodic inspection?

Periodic inspection and testing should be carried out only by electrically competent persons, such as registered electricians.

When does a periodic inspection need to be carried out?

It is recommended that periodic inspection and testing is carried out at the following times:

  • for tenanted properties, every 5 years or at each change of occupancy, whichever is sooner
  • at least every 10 years for an owner-occupied home
  • at least every 5 years for a business

The Landlords and Tenant Act 1985 requires landlords of properties with short leases to keep the electrical wiring in repair and in proper working order. We recommend landlords arrange for periodic inspection and testing to be carried out by a registered electrician at the relevant intervals shown above.
