PAT testing law requires that all landlords, employers and even self-employed individuals make sure that their portable electrical appliances are safe and are suitable and used for the purposes intended. These appliances should always be maintained properly and remain in good working order.
PAT testing is done to ensure that all electrical equipment that is classified as “portable” is deemed safe for use. The legislation deems that any competent person can perform it by using a PAT instrument or tester. The visual examination of each appliance in addition to the actual PAT test should be performed only by someone who is deemed competent.
Portable Appliance Testing, also known as PAT testing, is the examination or inspection of electrical appliances and equipment that ensures they are safe to use.
PAT testing ensures the appliances and equipment are safe and helps to prevent electrical accidents in the workplace. PAT testing should be done on a routine basis and clear and concise records should be documented.
A PAT test checks electrical items to ensure they are safe to use. It should include both a visual examination and a more in-depth examination. The majority of electrical defects can be detected during the visual examination.
However, some electrical safety defects can only be found when the appliance is tested using specialist PAT testing equipment.
The Health & Safety Executive (HSE) advises that PAT testing should include three steps – user checks, a formal visual inspection and the manual PAT test using a portable appliance tester.
All users of electrical equipment should have some basic training in how to use the equipment safely, as well as what danger signs to be aware of, as part of their induction. Users should feel confident in visually checking the equipment regularly for obvious signs of damage, as well as potential risks, such as cables trapped under desks or water hazards.

Prior to the manual PAT test, a formal visual inspection of the equipment should be carried out. According to the HSE, this process usually flags up around 90% of problems and it can be carried out by a competent member of staff with the relevant training, or a professional.
It is essential that the equipment is turned off and unplugged before beginning the visual inspection. The checklist should include:
