The Electricity at Work Regulations 1989 require that any electrical equipment that has the potential to cause injury is maintained in a safe condition.


The meaning of PAT Portable appliance testing (PAT) is the term used to describe the examination of electrical appliances and equipment to ensure they are safe to use.

The Electricity at Work Regulations

The Electricity at Work Regulations place a legal responsibility on employers, employees and self-employed persons to comply with the provisions of the regulations and take reasonably practicable steps to ensure that no danger results from the use of such equipment. This in effect requires the implementation of a systematic and regular programme of maintenance, inspection and testing.

The level of inspection and testing required is dependant upon the risk of the appliance becoming faulty, which is in turn dependant upon the type of appliance, the nature of its use and the environment in which it is used.

The Institution of Electrical Engineers published the “Code of Practice for In-service Inspection and Testing of Electrical Equipment”. This guide forms the basis for portable appliance testing in the U.K.
