PAT Testing

Portable Appliance Testing

What is Portable Appliance Testing (PAT)?

Portable appliance testing is a procedure to maintain electrical equipment to prevent danger as far as is reasonably practical. All electrical equipment whether permanently connected or connected by plug and socket-outlet should be inspected and tested in accordance with the recommendations contained within the IEE Code of Practice.

Each test lasts only a few minutes depending on ease of access to the equipment

A full visual inspection is carried out checking for damaged flexes, plugs and equipment, incorrectly wired plugs and incorrectly rated fuses

Once the item passes the visual inspection the item is plugged into the portable appliance tester and a series of electrical tests are carried out

A label is then attached to the item showing the asset number, date when next test is due, and whether it passed or failed

The results are then sent back to our head office for processing where an Asset Register and Test Report is prepared and sent to you with the Certificate of Conformity

Why have PAT Testing carried out?

Important reasons for carrying out Portable Appliance Testing include:

  • Adherence to the Health & Safety at Work Act 1974
  • Compliance with the Electricity At Work Regulations 1989
  • Minimise Fire Risks due to faulty/damaged electrical equipment
  • Minimise Electric Shock Hazards due to faulty/damaged electrical equipment
  • Insurance companies cannot dispute claims for damage through fire because of insufficient electrical maintenance
  • Maintain the safety of employees, visitors and customers


Types of Electrical Equipment?

Potable Appliances

A portable appliance of not more than 18kg in mass that is intended to be moved whilst in operation or an appliance that can be easily moved from one place to another, e.g. toaster, food mixer, kettle.

Movable Equipment (sometimes called transportable)

An item of movable equipment that is either 18kg or less in mass and not fixed, e.g. an electrical compressor, or equipment with wheels, castors or other means to facilitate movement by the operator as required to perform its intended use, e.g. air conditioning unit.

Hand-held Appliances

A hand-held appliance or portable equipment intended to be held in the hand during normal use, e.g. angle grinder, power drill, hedge cutter, soldering iron, iron, hair dryer.

Stationary Equipment

Stationary equipment that has a mass exceeding 18kg and is not provided with a carrying handle, e.g. refrigerator, washing machine or dishwasher.

Fixed Equipment

Fixed equipment is fastened to a support or otherwise secured in a specified location, e.g. central heating boiler, hand dryer, fixed air-conditioning unit, bathroom heater, electric towel rail or immersion heater.

Appliances or Equipment for Building-in

An appliance or equipment for building-in is equipment intended to be installed in a prepared recess such as a cupboard or similar. In general, equipment for building-in does not have an enclosure on all sides, e.g. a built-in electrical cooker.

Information Technology Equipment

Information technology (IT) equipment includes electrical business items such as computers and mains powered telecommunications equipment for general business use, such as mail processing machines, electric plotters, trimmers, VDUs, data terminal equipment, typewriters, telephones, printers, photocopiers, power packs etc.

Extension Leads and RCD Extension Leads

An extension lead is necessary where an item of equipment needs to be supplied but a convenient socket-outlet is not available. An RCD extension lead is an extension lead that includes an RCD.

Multiway Adaptors and RCD Adaptors

Multiway adaptors or multi-plugs are used where there are insufficient socket-outlets available. RCD adaptors are used to provide protection for persons using portable equipment, particularly for persons using portable equipment outdoors.
