What is Portable Appliance Testing (PAT)?

Portable appliance testing (PAT) refers to the inspection and testing of electrical appliances and equipment to assure their safety. Most electrical safety problems can be seen visually, however other types of defects can only be detected by testing. I t is critical to recognise visual examination is an important component of the process because some types of electrical safety defects cannot be found just by testing. The best way to ensure your appliances are electrically safe is to have a PAT test carried out 

What does PAT Testing include?

PAT testing is divided into two processes. The Visual Inspection and the Testing. Prior to actually carrying out a PAT test an inspector will carry out a thorough visual inspection to ensure no obvious damage is present. Once satisfied the inspector will use a calibrated PAT tester to carry out a series of tests and the readings will determine if the appliance is safe to use.

Is PAT Testing a legal requirement?

PAT testing is a legal requirement in the UK. The Health and Safety at Work Act 1974 and the Electricity at Work Regulations 1989 impose a legal duty on employers, landlords, and self-employed individuals to ensure the safety of electrical appliances and equipment. PAT testing is a crucial part of fulfilling this duty by examining and testing portable electrical appliances to ensure they are safe to use.

The frequency of PAT testing depends on the type of appliance and the environment in which it is used. The Health and Safety Executive (HSE) provides guidance on the recommended intervals for testing different types of equipment. Generally, portable electrical appliances in a low-risk environment should be tested at least every two to four years. However, higher-risk environments such as construction sites or industrial settings may require more frequent testing.

It’s important to note that the specific legal requirements for PAT testing may vary based on the industry and the nature of the work being carried out. Different sectors, such as healthcare or education, may have additional regulations or guidelines that mandate more frequent testing.

To comply with the legal requirement for PAT testing, it is advisable to engage a competent person or a qualified electrician to carry out the testing. They will conduct visual inspections, perform electrical tests, and provide necessary documentation and labels for each appliance tested.

It’s always recommended to consult the latest regulations and guidance from authoritative sources such as the HSE or seek professional advice to ensure compliance with the legal requirements for PAT testing in the UK.
