FAQ: How long does a PAT testing certificate last?

Realistically speaking a PAT certificate expires as soon as the test is over and someone starts using the appliance again, because the results obtained can’t predict the future, but in reality most people consider a PAT testing certificate to last around one year.

However, how long the time period should be until the appliances are tested again very much depends on a risk assessment.

If you have electrical appliances in use at work you should carry out regular risk assessments to determine what is required to ensure they maintain safe standards; this could be annual PAT tests. 

Usually a PAT test is carried out and the engineer would recommend an interval until next tests are due.
