The testing of electrical installations and equipment is important when it comes to safety of persons and property. Due to electrical faults many homes and work places pose a risk from electrocution or fire. It is not just a safety issue, it is the law.

Every electrical installation deteriorates with use and age. It is important for the person responsible for the maintenance of the installation to be sure that the safety of users is not put at risk, and that the installation continues to be in a safe and serviceable condition.

A Periodic Inspection is an inspection on the condition of an existing electrical installation in order to determine, so far as is reasonably practicable, whether the installation is in a satisfactory condition for continued service.

The fundamental reason for inspecting and testing an electrical installation is to determine whether new installation work is safe to be put into service, or whether an existing installation is safe to remain in service until the next inspection is due.

The frequency of testing being required is dependant on the age and type of property and its use. It is also recommended that property is inspected and tested when it is being let or sold or when buying a previously occupied property.
