By Casey Midgley, Arlite Energy Last reviewed 30 October 2026 4 minute read **No DIY.** Electrical work must be done by a licensed electrician.

Frequently asked questions Power points do not have a fixed expiry date, but they do wear out with age, heat and use. Loose-fitting plugs, cracks, scorch marks, discolouration and buzzing are signs one needs attention. Replacing a power point is electrical work that must be done by a licensed electrician in Queensland, so look, make notes and call rather than touching it. ## How long does a power point last? There is no single lifespan. A power point in a spare bedroom that rarely gets used can last for decades. One that runs a heater or a kettle every day, or sits in a hot or damp spot, is likely to wear faster. Inside the outlet are metal contacts that grip the plug pins and connections that hold the wiring in place. Over years of plugging and unplugging, and repeated heating and cooling, those contacts can loosen. A loose connection resists the flow of electricity, and that resistance turns into heat. ## What signs mean a power point is wearing out? You can spot most of the warning signs by looking and listening, without touching anything. Watch for: - A plug that falls out easily or sits loosely in the outlet. - A cracked, chipped or loose faceplate. - Brown or black marks, scorching or discolouration around the outlet or on a plug. - A buzzing, crackling or sizzling sound. - A faint burning or hot-plastic smell. - Plugs that have melted or deformed. Any one of these is a reason to stop using that outlet and have it checked. If it is hot, scorched or smells of burning Stop using the power point, do not touch it, and keep children and pets away. Heat, scorch marks or a burning smell can mean a loose connection that is a fire risk. If you see smoke, sparks or flames, leave the building and call **000**. Otherwise, contact a licensed electrician as soon as you can. See also our guide to *burning smells and hot power points*. ## Why does a licensed electrician need to replace it? A power point looks simple, but it is connected to the permanent wiring of the home. Replacing one involves working on that wiring, and a fault in the work can lead to shocks or fires that may not appear for months. In Queensland, electrical work must be done by a licensed electrician, and the Electrical Safety Office Queensland is the regulator. An electrician will also look at what is behind the outlet, because a worn power point is sometimes a symptom of heat damage or overloading on the circuit, not just old age. ## Will a worn power point affect my other outlets? It can. Outlets on the same circuit share the same wiring, so a loose connection at one point can sometimes show up as heat, flickering or tripping elsewhere. That is one reason a proper inspection is better than swapping out a single outlet. ## Are older homes more likely to have worn power points? Often, yes, simply because they have had more years of use and heat cycles. Older homes may also have older wiring behind the outlets. The age of the home is a reason to ask a licensed electrician for an inspection if you see any warning signs, not a reason to assume everything is fine or failing. ## How can I make it easier to get the right help? Describing the problem clearly saves time and helps the electrician bring the right parts. Use the steps below. ## What to note before you call an electrician 1. Mark which outlet — Note the room and the position of the power point, and whether other outlets nearby have similar signs. 2. Photograph what you can see — Take clear photos of marks, cracks or discolouration from a safe distance, without touching or moving anything. 3. Note what it runs — Write down what is normally plugged in there and for how long each day. 4. Record the timing — Note when you first noticed the sign, and whether it is getting worse. ## Frequently asked questions - Look for scorch marks, cracks, discolouration, melted plastic, a loose-fitting plug, buzzing or a burning smell.
