Portable Appliance Testing

Why and when do I need my appliances PAT testing?

Common law and the Health and Safety legislation imposes duties of care upon those responsible for buildings, particularly employers in regard to the supply of portable electrical equipment, its use, and maintenance and testing.

If you have a business or are a landlord that permits, or allows employees, tenants or members of the public to use portable electrical equipment that can be plugged in to the electrical mains systems then you must have this tested and inspected to ensure it is safe to use. This might be anything from white goods, kitchen appliances, decorative and task lighting, office and cleaning equipment or hand tools. All employers should carry out risk assessments to assess how and when the portable appliances will be used and formally tested.

Employers should train staff and personnel to check the portable appliances before use each time to see if they consider them safe to use and that there no bare or exposed wires etc. They must also decide upon a strategy for the periods between formal PAT testing of appliances taking place, which can vary from 1-4 years.

What does the PAT Testing involve?

Any item that is readily accessible and can be unplugged by the engineer will be visibly inspected for and tested and defects, the operation of the appliance will be checked and then the item will undergo various PAT tests to ensure its integrity and that it is safe to use.

The Flex-check is carried out to check flexible cable for any damage and also make sure that it is free from any abrasions cuts and stress or breaks. The plug is checked to ensure that the flexible cable is secure and is correctly wired, the fuse is of the correct rating for the appliance and it is free from any sign of overheating and in good condition.

Using calibrated test equipment Earthloop engineers will visit your premises to carry out the PAT testing, which includes:

  • Polarity Test (only carried out on extension cables and supply leads)
  • Earth Continuity Test (not carried out on Class II appliances that have no earth)
  • Insulation Resistance test
  • Operational Test
  • Earth leakage Test
  • Computer Soft Test


Reports & Certification

During testing all appliances are issued with a unique asset number. After portable appliance inspection & testing has been carried out, a pass or fail label will be applied to the asset, which will then be dated & signed. Any failed items will be taken out of operation at the time of PAT testing and the client is advised if they require repair or replacement.

What happens after PAT Testing?

A full report and certificate which confirms compliance of the PAT tested equipment is issued. You should remove any faulty equipment from use and instigate repairs or replacement. You will be breaking the law and regulations under the HSAWA (The Health & Safety at Work Act 1994) if you fail to do this and someone is injured or killed using a faulty appliance that you have been notified of.

We will be pleased to advise on the cost of repairs to leads and plugs if so required.
