PAT testing is a SAFETY SERVICE not an Electrical Service.
Your PAT Service provider should deliver to a standard that ensures COMPLIANCE under the Safety Health and Welfare at Work legislation:
Are the testers TRAINED in the CODE OF PRACTICE for PAT testing (typically City and Guilds 2377) thus ensuring they know the correct tests to perform and how to complete them.
Will your appliances be automatically BAR CODE ASSET TAGGED from the test equipment or will the cheaper hand written labels be used with the added risk of human error.
Will the test data be stored and uploaded into a database for the automatic production of REPORTS thus ensuring FULL TRACEABILITY from Asset Tag to Report.
Are the testers familiar with and COMPETENT in IT equipment and be experienced to the extent that you are confident of them handling your critical IT appliances.
