PAT Testing



‘PAT’ stands for ‘Portable Appliance Testing’.

There is no definition of what a ‘Portable Appliance’ is in the current legislation, however the standard interpretation is “any appliance that has a plug attached to it and plugs into a wall outlet”.

Because of this, the word ‘portable’ is slightly misleading. There are actually 7 categories of appliance which should be considered for PAT testing or at least, visual inspections:

–   Fixed appliances
–   Stationary appliances
–   IT appliances
–   Moveable appliances
–   Portable appliances
–   Cables and chargers
–   Hand Held appliances


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.

Because PAT testing is one of the most effective ways to do this, particularly for high risk or large, complex environments, it has become  a standard way of meeting this legal obligation.
