PAT testing, or Portable Appliance Testing, is required in the UK to ensure that all electrical appliances in a workplace or public space meet the necessary safety standards. The Electricity at Work Regulations of 1989 require that all electrical equipment in the workplace is safe to use and regularly inspected and maintained. PAT testing is an effective way to ensure that all appliances are fit for purpose, and that any potential electrical hazards are identified and dealt with before they can cause harm to people or property. By carrying out regular PAT testing, employers and landlords can demonstrate their commitment to ensuring the safety of their staff and customers, and comply with UK health and safety regulations.
