What is PAT Testing & why should I get my electrical items checked?

Portable Appliance Testing (PAT) is the term used to describe the examination of electrical appliances and equipment to ensure they are safe to use. Most electrical safety defects can be found by visual examination but some types of defect can only be found by testing. However, it is essential to understand that visual examination is an essential part of the process because some types of electrical safety defect can’t be detected by testing alone. 

The UK Provision and Use of Work Equipment Regulations 1998 (PUWER) states at Regulation 4(1): “Every employer shall ensure that work equipment is so constructed or adopted as to be suitable for the purpose for which it is used or provided.”

The Electricity at Work Regulations 1989 states at Regulation 4(2): “As may be necessary to prevent danger, all systems shall be maintained so as to prevent so far as reasonably practicable, such danger.”

This means that employers (and the self-employed) must ensure that all electrical work equipment is safe, suitable for the purpose and properly maintained in good order.

The scope of the legislation covers everything from small portable equipment e.g. hand drills to fixed 400 kV distribution systems. The requirements apply to fixed and “hard-wired” electrical appliances (or equipment), such as hand driers in washrooms or ovens in commercial kitchens, in addition to portable and hand-held appliances which plug-in, such as drills or vacuum cleaners, both single and three phase. Different inspection and maintenance regimes are recommended for fixed electrical installations and portable electrical equipment.
