Pat testing or portable appliance testing is an important part of any health & safety policy.



PAT Testing is only one of the services we offer. Please contact us for details.


Health & Safety Executive

The Health & Safety Executive states that 25% of all reportable electrical accidents involve portable appliances. The Electricity at Work Regulations place a legal responsibility on employers, employees and self-employed persons to comply with the provisions of the regulations and take reasonably practicable steps to ensure that no danger results from the use of such 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:

1. Where appliances are used by employees.

2. Where the public may use appliances in establishments such as hospitals, schools, hotels, shops etc.

3. Where appliances are supplied or hired.

4. Where appliances are repaired or serviced.




All portable appliances with a mains plug need testing.


This includes:

  • Computers, monitors and peripherals requiring mains power
  • Audio and telephone equipment requiring mains power
  • Kettles, microwave ovens and other kitchen appliances
  • Vacuum cleaners
  • Extension leads

All portable electrical equipment is subject to getting damaged during use, and this damage could render the equipment dangerous to the user. Without a regular programme of testing and inspection, you have not taken reasonable steps to ensure the safety of users.

In the Health & Safety At Work Act 1974, all employers have a legal duty to provide safe plant and equipment and every employer must ensure that equipment must be maintained in an efficient state, in efficient working order and good repair.




The HSE recommend a three-stage process for this.

User checks.

Advising the user of potential danger signs can result in problems being picked up before they can result in any danger. For example, if the power cable is frayed or the plug is cracked, users need to be advised NOT TO USE the appliance and report the fault to a supervisor. This information can be put across, say by the use of a poster or in a memo.

Formal visual inspections.

This is a process of simply inspecting the appliance, the cable and the plug for any obvious signs of damage.

Combined inspections and PAT testing.

At periodic intervals, it is essential to test the portable appliances to measure that the degree of protection to ensure that it is adequate. At these intervals, a formal visual inspection is carried out and then followed by PAT testing.
