Fixed Installation Testing, commonly referred to as Periodic Inspection and Testing, involves a comprehensive evaluation of a property's electrical wiring. The process identifies potential defects that could pose safety risks. Building owners have a responsibility to ensure the safety of occupants and users of their properties.

While often overlooked, electrical wiring is a critical component of building safety. Faulty wiring can lead to fires or electric shocks, emphasizing the importance of adherence to safety standards. The legal framework for electrical safety is defined in the Electricity at Work Regulations 1989, which mandates:

• Electrical systems must be constructed to minimize risks as much as reasonably possible.
• Systems must be maintained to prevent hazards effectively.
• Work involving or near electrical systems must be conducted in a way that minimizes danger.
• Protective equipment provided for working on or near electrical systems must be fit for purpose, well-maintained, and correctly used.

The Importance of Fixed Installation Testing

The Health & Safety Executive (HSE) advocates for regular inspection and testing in workplaces to meet regulatory requirements. Periodic testing is essential as electrical systems naturally degrade over time due to factors like wear, environmental exposure, excessive loading, and ageing.

The standards for Fixed Installation Testing are outlined in the latest edition of BS 7671. The required frequency of testing depends on the type of property, but compliance with IET Wiring Regulations is mandatory for all electrical installations.
