PAT Testing


Cambridge Risk Management specialise in Portable Appliance Testing.

PAT Testing is to help you meet your Health and Safety Requirements

What is a Portable Appliance?

Portable equipment which is not part of a fixed installation but when used is connected to a fixed installation (or a generator), by means of a flexible cable, plug and socket constitutes a portable appliance. It includes equipment that is hand held or hand operated while connected to the power supply. It also includes extension leads, power leads, plugs and sockets, and cord sets that supply portable equipment and are not part of the fixed installation, since they operate in the same environment and are subject to similar use as the equipment they serve.

Why is a Portable Appliance Test needed?

  • To make sure it’s safe to use
  • To make sure your company meets the requirements of the Provision and Use of Work Equipment Regulations
  • To make sure your Insurance is valid
  • To meet Health & Safety requirements
  • To meet the requirements stated in The Electricity at Work Regulations

What does the PAT Testing engineer do when testing?

The engineer does a formal visual inspection and an electrical test.

The formal visual inspection  part checks for the following

  • Is the appliance in general good condition and suitable for the use.
  • The appliance Is it working? (Function test)
  • The lead Is it in good condition and safe?
  • Is it free from damage and nicks or cuts which could cause injury?
  • Is the cable fitted properly to the plug?
  • Does it switch on and off properly to allow you to isolate the power if needed?
  • Is there any damage to the external parts?
  • is the correct fuse fitted? We check the rating
  • Are there any signs of internal damage or signs of tampering ?

A Safety Test is then carried out.

  • Earth Continuity Testing  (Class 1 equipment)
  • ​Insulation Resistance Testing (Class 1 and 2)
  • ​Protective Conductor/Touch Current Testing
  • ​A Functional Check – we power up the appliance to ensure that it is working normally

The appliance is then labelled accordingly as a PASS or FAIL and indicating the date due for next inspection or just the test date (4th Edition).

Test Frequency

We follow the 3rd and 4th Edition IEE Code of Practice for In-Service Inspection and Testing of Electrical Equipment.
