What is Electrical Equipment Testing (EET)?

Electrical Equipment Testing (EET) is a broader term used to refer to Portable Appliance Testing (PAT) and Fixed Appliance Testing (FAT). Both involve the inspection and testing of electrical equipment to ensure it is well maintained and safe to use. Whether you manage a single site or a multi-location estate, Complii provides reliable, efficient, and fully documented testing to help you meet your legal obligations, under the Electricity at Work Regulations 1989, and to ensure your people and property are protected.
