PAT testing

Pat testing or portable appliance testing is a procedure done to guarantee a good health & safety policy in your work area.

It’s a common knowledge that 25% of all electrical accidents involve the portable appliances. That´s why regulations and reasonably practicable steps were established, intending to ensure that no danger result from the use of such faulty equipment. This in effect requires the implementation of a systematic and regular program of maintenance, inspection and testing.

The Health & Safety at Work Act (1974) places such an obligation in the following circumstances:


There are numerous risks which are to be found in electrics and appliances that is why we give a very thorough inspection and test on every appliance; the main cause of injury or death within the workplace is due to faulty equipment which could easily be avoided through regular checks and tests on each appliance in your premises

Common faults found

  • No earth
  • Reversed polarity in plug heads
  • Damaged flex
  • Wrong fuse ratings
  • Appliance casing damaged or missing
  • Terminals loose in plugs
  • Incorrect cable core on extension cables

Why PAT Test your business?

  • Where appliances are used by employees.
  • Where the public may use appliances in establishments such as hospitals, schools, hotels, shops etc.
  • Where appliances are supplied or hired.
  • Where appliances are repaired or serviced.

The level of inspection and testing required depends upon the risk of the appliance becoming faulty, the nature of its use and the environment in which it is used.

The Institution of Engineering and Technology (The IET) published the "Code of Practice for In-service Inspection and Testing of Electrical Equipment". This guide forms the basis for portable appliance testing in the United Kingdom. We practice our services according to this Code of Practice.

What needs to be tested?

  • Portable appliances: An appliance of less than 18kg, that can easily be moved whilst in operation or not.
  • Movable equipment (transportable): Equipment with wheels, 18 kg or less and not fixed.
  • Hand Held equipment: Intended to be held in the hand while operating.
  • Stationary equipment: Equipment over 18 kg and not intended for being portable
  • Fixed Equipment: All appliances fixed to a support and secured in a specified location.
  • Information technology equipment: All electrical business equipment such computers, photocopiers, projectors, printers, etc.

How frequent do I need to test?

The Health & Safety Executive offers no absolute rules on the frequency of the testing and inspection of portable appliances. The Memorandum of Guidance on the Electricity at Work Regulations only suggests that 'regular' inspection should be carried out. But it absolutely depends on the kind of appliance, the environment and the users of the appliances.

The frequency should be adapted to meet the requirements for preventing danger and ensuring safety for the users.

Electrical faulty appliances can be the cause of injury or death within workplace or habitable areas, being a risk that can be easily avoided. Through regular checks, thorough inspection and electrical testing the appliances you reduce this risk to the minimum.
