Portable appliance testing (PAT) is an important part of ensuring electrical safety in the workplace. While not every item must be tested, many appliances pose risks if they are not properly maintained. Understanding which appliances need testing helps you stay compliant and protect your people, property, and business.

What is PAT testing?

PAT testing involves the inspection and testing of electrical appliances to check they are safe for use. It typically combines:

• A visual check for signs of damage

• Electrical tests to confirm the appliance is operating safely

• A pass or fail label for easy identification

• A record of the inspection for compliance purposes

Appliances that usually require PAT testing

The types of appliances that should be considered for PAT testing include:

• Computers and IT equipment such as monitors, printers, and chargers

• Kitchen appliances including kettles, microwaves, and toasters

• Office equipment such as photocopiers, shredders, and extension leads

• Cleaning equipment including vacuum cleaners and floor polishers

• Portable power tools used in workshops or maintenance environments

In general, any appliance that plugs into the mains and is used regularly in a work environment should be tested.

Factors to consider

The frequency of PAT testing depends on factors such as:

• The type of equipment

• How often it is used

• The environment it is used in (for example, construction sites typically require more frequent testing)

A qualified engineer will advise on an appropriate testing schedule to keep you compliant.
