Portable Appliance Testing
Portable appliance testing or PAT Testing is the process of checking electrical appliances for safety through a series of visual inspections and electronic tests.
Why do I need to have my appliances tested?
The best way of ensuring that your appliances are safe is to have a PAT test carried out on them. This is a good way for landlords to ensure that they are meeting their legal obligations to maintain high standards of electrical safety in their rented property.
What does Portable Appliance Testing involve?
To establish the safety and suitability of your electrical appliances, the competent person will carry out a visual inspection of the appliance, its plug and lead. For Class I equipment they will also inject test signals into the cable and appliance to ensure their integrity.
Who should do the work?
Electrical work must only be carried out by people who have the necessary knowledge, skill and experience needed to avoid danger to themselves and others.
Many registered electricians will carry out portable appliance testing. You can find a registered electrician here.
What will I receive?
Upon completion of the portable appliance inspection and testing you should receive a report that details the following as a minimum:
- An inventory containing each appliance type, name, location and description
- A full set of test results for each appliance tested
- A full list of any failed items with an explanation of their failure
- A visible pass or fail label on each appliance detailing the inspection date, next test due and the inspector’s signature.
If you are not technically aware, then the contractor / competent person who carried out the inspection and testing should be happy to talk through your report with you and advise you of any further action required.
 Class I equipment relies on the presence of an effective protective (earth) conductor for reasons of safety.
