As technology advances, we are moving towards a more wireless world. Cordless equipment and battery-operated tools are becoming increasingly popular in various industries. But, do these types of equipment and tools need portable appliance testing (PAT testing)? PAT testing is a routine procedure that ensures the safety of electrical equipment and prevents electrical hazards in the workplace.
However, there seems to be some confusion regarding whether cordless equipment and battery-operated tools need to undergo PAT testing or not. In this article, we explain whether cordless equipment and battery-operated tools require PAT testing. We also explore the reasons why PAT testing is important and how it helps in ensuring the safety of workers.
What is portable appliance testing?
Portable appliance testing (PAT) is a process of testing and inspecting electrical appliances to ensure that they are safe to use. It is typically carried out by qualified electricians or PAT testing specialists and involves a series of checks to verify that the appliance is functioning correctly and does not pose a risk of electrical shock or fire.
The portable appliance inspection process involves several steps, including:
- Visual inspection: The tester will visually inspect the appliance to identify any damage, defects, or other visible signs of wear and tear. The visual examination includes checking for any exposed wires, loose connections, and damaged plugs or cords.
- Electrical testing: The appliance is tested to verify that it is correctly earthed and that there are no faults in the wiring or circuitry. This is typically done using a portable appliance tester, which can check for insulation resistance, earth continuity, and other electrical parameters.
- Functional testing: The tester will check the appliance’s functionality to ensure that it is working correctly and performing its intended functions safely. This may include testing the temperature control on a toaster or oven or checking the safety cut-off feature on a power tool.
After the testing is complete, the appliance will be marked as having passed or failed the inspection, and a detailed report will be provided to the owner of the appliance. If any faults or defects are identified during the testing process, the tester will recommend appropriate action to repair or replace the appliance to ensure it meets safety requirements.
PAT testing is typically carried out in workplaces and other public areas where electrical appliances are used frequently, such as offices, schools, and hospitals. However, it is also recommended that homeowners have their electrical appliances tested periodically to ensure their continued safety.

Additionally, certain types of battery-operated equipment, such as power tools or medical devices, may have additional safety requirements that need to be met to ensure their safe operation.
Do cordless power tools need to be PAT tested?
Cordless power tools should be considered for PAT testing to ensure their safety, as they are still electrical appliances that can pose a risk of electrical shock or fire if not properly maintained or if faults develop over time.
While cordless power tools are not directly connected to the mains’ electricity supply, they typically include rechargeable batteries that may need to be charged using a mains-powered charger or adapter. These charging units may also need to be tested as separate electrical appliances to ensure their safety.
PAT testing for cordless power tools typically involves a visual check to identify any visible signs of damage or wear and tear, as well as electrical testing to verify that the tool is correctly earthed and that there are no faults in the wiring or circuitry. The tester may also check the tool’s functionality, including the safety cut-off feature, to ensure that it is working correctly and performing its intended functions safely.
The frequency of PAT testing for cordless power tools will depend on a number of factors, including the type of tool, its intended use, and the environment in which it is being used. Employers have a legal obligation to ensure that electrical equipment is safe for use and should conduct a risk assessment to determine the appropriate frequency of PAT testing based on their specific circumstances.
What are signs that you need to PAT test equipment?
There are several signs that you may need to PAT test your electrical equipment to ensure its safety. These include:
