The Electricity at Work Regulations apply legal responsibility on employers and employees in order to act accordingly with regulations and take reasonable steps to ensure that accidents do not result from the use of a portable appliance, which is why it is important to complete a portable appliance test (PAT). It is highly recommended that a portable appliance test (PAT) is completed in order to maintain health and safety at work. A portable appliance test (PAT) depends on the risk of the appliance becoming faulty.

The National Association of Professional Inspectors and Testers (NAPIT) defines a portable appliance as “any electrical item which is intended to be moved whilst connected to an electrical supply”. The IEE Code of Practice highlights regulations on which type of portable appliance test (PAT) a certain appliance requires because the type of portable appliance test (PAT) carried out varies depending on the size and usage of an appliance.
