If you have had a recent inspection visit from your Health & Safety, Fire Officer or a call from your insurance supplier to renew your policy you may just remember that one of the first questions that they will ask is whether you have been PAT Tested. If your answer is no then you could possibly be looking at paying more for your insurance or asked to get your workplace tested before your inspection is passed. Portable Appliance Testing more commonly known as PAT Testing, involves the checking of any equipment which has an electric plug. This testing involves visual checks, and combined inspection and testing using a PAT testing meter. There are 4 main sets of legislation that are applicable to the inspection and testing of in service electrical equipment.
