About Pat Testing

A PAT test is a routine inspection of some types of electrical appliance to check they are safe to use. Its purpose is to prevent electrical accidents in the workplace.

A full PAT test should include both a visual inspection and a more in-depth check using specialist PAT testing equipment.  This test includes earth continuity, lead polarity, and insulation resistance checks.

Some appliances only need a reduced test, called a PAT insulation test.

At the end of a PAT test, every appliance should be marked ‘passed’ or ‘failed’. Ideally there should be a record of the results.

Not all electrical items need to be PAT tested.

PAT testing is not, in itself, a legal obligation.

However, current UK legislation states that businesses must maintain electrical equipment in a safe condition.

They also have a legal responsibility to ensure the safety of employees and the public.
