What Is PAT Testing?
Portable Appliance Testing (PAT testing) is the process of inspecting electrical appliances to ensure they are safe to use. Businesses carry out PAT testing to identify electrical faults, damaged cables, insulation issues, and other hazards that could lead to electric shocks or fires. In workplaces where electrical equipment is used regularly, routine testing helps maintain a safe environment for employees and customers.
PAT testing usually involves two main stages. First, the tester performs a visual inspection of the appliance, plug, and cable to check for obvious damage. Then, specialised PAT testing equipment is used to measure electrical safety parameters such as earth continuity and insulation resistance. These checks confirm whether the appliance is safe to operate.
Although the term “PAT testing” is widely used, it is actually part of broader electrical safety maintenance. UK safety regulations require employers to ensure that electrical equipment does not pose a risk to users. Therefore, PAT testing has become one of the most practical and widely used methods to help organisations meet these safety responsibilities.
