Portable Appliance Testing is part of your Health and Safety at Work procedure. The UK Health and Safety at work act requires employers to take reasonable practical steps to ensure that no danger will result from using portable electrical appliances in the following locations:

A breakdown of our PAT Testing process: 

Visual Inspection.

Our fully qualified Engineer will conduct a visual inspection of your appliances, flex and plug top in order to ensure that there are no visual signs of overheating or damage.

They will then proceed to open each top plug and inspect the fuse and wire connections. If required, they will tighten the connections.

Electrical Testing.

We will then proceed to put each appliance through a series of electrical tests that will ensure each appliance is correctly earthed and insulated. This testing process incorporates the following tests:

  • Earth Continuity Test
  • Insulation Resistance
  • Polarity Test
  • Earth Leakage Test

In the instance of an appliance failing the test, we will carry out FREE minor repairs which include free fuse and plug top changes.


Once the electrical testing is completed, a compliance label is affixed to each appliance. This label includes the following information:

  • Whether the appliance has passed or failed the test
  • PAT testing/retesting date
  • Appliance ID number

Asset Recording.

Our engineer will provide you with a detailed asset record that includes each appliance tested and an inventory summary. We will provide you both a hard copy and electronic copy of this report.
