What you should know about PAT Testing

Updated: Jul 5

There are many common myths about PAT (portable appliance testing) out there, and you may be wondering if you need it done, or simply how you maintain your electrical appliances. Here we will tell you all you need to know about PAT and bust many misconceptions about the process.

What is PAT Testing?

PAT testing is the maintenance and safety checking of all electrical appliances with a plug. All electrical testing should be carried out by an electrician, each of your devices will be checked to meet the highest standards of safety. As well as this, you will have a full inventory of all electrical products in your building which includes the type, description and location. And all tested items have a pass/fail sticker on them, so you can maintain your items.

Why do I need PAT Testing?

Maintenance. With the Electricity at work regulations 1989, it has become a legal obligation to keep your electrical equipment functional and safe. PAT testing is a cost-effective and efficient way to make sure each of the appliances in your home, or office are safe and ready to be used.

How often do I need to PAT test my items?

You won’t need to PAT test your items often. Once done, your items are ensured as safe, and you can then perform infrequent checks on them to ensure they aren’t broken or damaged.

PAT testing is not only affordable but a great way to take a hands-off approach to the checking of your items. The process doesn’t take a lot of time, regardless of the number of items you have to test, and once done, your items will be deemed safe and tested by a competent person.


How does PAT testing work?

The process is simple. Your PAT tester, who needs to be a competent person or professional electrician, will first carry out a visual inspection of the appliance components such as the plug, the cable and the socket.

Your PAT tester will also survey the environment that your appliances are in and see if that is fit for their purpose.


After that, your tester will use a device that will test the earth continuity, lead polarity and insulation resistance. A sticker is placed on the item, and the process is completed.

Should an item fail, then it needs to be removed and not used again.

Following the PAT test

After the PAT test, you can keep up the maintenance of your electrical items when you choose. Your tester may give you advice on how often you need to check your items, but ultimately it is up to you.
