What is PAT Testing?

PAT (Portable Appliance Testing) is the routine inspection of plug-in electrical equipment to verify it is safe to use. The Health and Safety Executive requires employers, landlords and event organisers to maintain electrical equipment in safe condition; PAT testing is the most common evidenced approach. Test intervals vary by appliance class and environment, from three months for site tools to four years for office IT. Testers should be competent — typically City & Guilds 2377 qualified.
