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

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.
