Are your extension leads safe? (PAT Testing)



Many portable electrical items such as lamps and radios are supplied with short cables. So sometimes the use of extension leads can be unavoidable, but it is important to consider the following:

  • Only use extension leads fitted with suitably insulated connectors and plugs. Never join two lengths of flexible cable by twisting the bare ends of wires together.

  • Damaged cable, due to leads being walked over, continually bent at the same point or stored badly.

  • You can trip or fall over taut, over-stretched cable.

  • Always check that leads, plugs and sockets are undamaged.

  • Always check the extension lead plug contains the correctly rated fuse for the equipment being used.

  • If using a cable drum extension lead, it should be completely unwound to avoid overheating.

  • For general use, 2-core extension leads should not be used.

Some appliances use more power than others, so be mindful of not overloading your extension leads. Power-hungry appliances such as kettles, toasters and microwaves shouldn't be on the same extension.

It's also important to fully unwind drum extensions leads. If you leave them coiled, they can overheat and cause a fire. An extension lead should only be used when it is not possible to reach a wall socket with the equipment cable.


PAT testing, including a visual test, is a highly effective way to ensure extension leads are operating properly and are safe for use.
