What should be Pat Tested?
The simple answer to that question is anything connected to the mains supply via a plug and capable of being moved whilst still connected to the supply. This is not the whole story because even items that are not able to be moved, like a built-in dishwasher or heated towel rail also need to be Pat Tested
Portable appliance - an appliance of less than 18kg in mass that is intended to be moved whilst in operation or an appliance which can easily be moved from one place to another, e.g. vacuum cleaner, toaster, food mixer, etc
Cordless power tools do not need testing but their battery chargers do.
Information technology equipment - includes electrical business equipment such as computers and mains powered telecommunications equipment, and other equipment for general business use, such as mail processing machines, VDU's photo-copiers
Power cords to IT equipment also need to be tested, however they need to be tested separately from their equipment, as these need to be tested to a different standard.
Electrical cable extensions particularly need PAT testing as these are one of the most common sources of hazard.
Fixed equipment/appliances - equipment or appliance which is fastened to a support or otherwise secured in a specific location, e.g. bathroom heater
