Frequently Asked



What Is PAT Testing?

Portable Appliance Testing (PAT Testing) is the term used to describe the examination and testing of electrical appliances and equipment, by a series of visual and electrical tests to ensure they are safe for use.


What Does PAT Testing Involve?

Each appliance to be tested, will receive a number of visual and electrical tests depending on the type and construction of the appliance. The visual checks are carried out first and include the following:

  • Checking the flex for damage
  • Checking the plug for damage, correct wiring and fuse, signs of overheating, harnessed flex
  • Checking the casing of the appliance for damage, missing switches etc
  • Checking the equipment is suitable for it’s environment

The electrical test/s are then carried out (depending on the class of appliance) and may include the following:

  • Earth continuity
  • Insulation resistance
  • Polarity
  • Earth leakage

What Will Be Received Once The PAT Testing Is Completed?

Upon testing completion, we will provide you with the following:

  • Failure report, completed by the engineer on the day
  • Fully itemised test report (within one working day of testing completion)
  • Pass certificate (within one working day of testing completion)

Is PAT Testing A Legal Requirement?

The law requires employers, companies, landlords etc must ensure their electrical equipment used by staff, members of the public, tenants etc is properly maintained in order to prevent danger. The law does not state how this should be done or how often. With a regular PAT Testing schedule in place, carried out by thorough, competent engineers, you will know your equipment meets these requirements and is safe to use.


How Often Should Appliances Be PAT Tested?

The frequency of inspection and testing depends upon the type of appliance and the environment it is used in. For example, a power tool used on a construction site is more prone to damage and should be tested more frequently than a lamp in a hotel bedroom. Appliances in an office that has sockets in the floor with trap door style covers are more prone to cable damage than appliances plugged into sockets that are placed at a waist high level and therefore should also be tested more frequently. 


What Could Happen If Appliances Aren't PAT Tested?

In the event of an incident, regarding an electrical appliance of yours. You would need to prove that you had a regular preventative maintenance schedule in place to avoid becoming liable. PAT Testing along with regular user visual checks would be one such program. Without being able to prove that such a program was in place, the responsible person would become liable and could face prosecution. Many insurance companies assume that when providing insurance cover to a business, the owners of that business are complying with all regulations necessary. An insurance company may reduce, delay or even refuse to pay out on a claim if an appliance that has not been tested has caused the damaged.
