5 Simple Electrical Checks You Can Do Before Seeing a Professional

When something goes wrong with your electrical system, your first instinct might be to call an electrician straight away. And while it’s always best to leave complex or hazardous issues to the experts, there are a few quick and simple checks you can safely do yourself before making that call. These basic inspections can often save you time and money — and sometimes, they might even solve the problem entirely. Here are five simple electrical checks you can do at home or in the workplace before seeking professional help.

• Check the Power Source: It sounds obvious, but this step is often overlooked. If an appliance or light isn’t working, make sure it’s actually plugged in and switched on. Try plugging it into another socket to confirm whether the issue lies with the appliance or the outlet itself. For battery-powered devices, check that the batteries aren’t flat or corroded.

• Inspect the Circuit Breaker: A tripped circuit breaker is one of the most common causes of power loss in specific areas of a home. Head to your switchboard and look for any switches that are in the ‘off’ position or sitting in between. Flip them back to ‘on’ and see if that resolves the issue. If a breaker keeps tripping, it’s a sign of a deeper problem that should be handled by a licensed electrician.

• Test Power Points and Switches: If you’re unsure whether a power point or light switch is functioning properly, you can use a power point tester or simply plug in a device that you know works. Listen and feel for any buzzing, excessive heat, or flickering — these are red flags that may indicate loose wiring or internal damage. If a switchplate is cracked or discoloured, that’s also a sign it may need attention.

• Look for Signs of Wear and Tear: Over time, cords and outlets can deteriorate, especially in older homes. Check your visible cables and extension leads for fraying, exposed wires, or scorch marks. These can be dangerous and are best replaced immediately. If you’re confident and have the right tools, you can learn how to crimp and solder wires to make minor repairs — but only if you’re certain it’s safe to do so.

• Reset Your Appliances: Many modern appliances have built-in safety mechanisms that shut them down when there’s an electrical issue. Before assuming the problem is with your wiring, try resetting the appliance. Unplug it for a few minutes, then plug it back in and power it up again. For items like washing machines, fridges, or microwaves, this simple trick can sometimes do the trick.

When in Doubt, Call a Professional

While these checks can help you identify minor issues or eliminate obvious causes, they’re no substitute for professional expertise. If you suspect a fault within your walls, your switchboard, or your home’s overall wiring, don’t take any risks — call a licensed electrician. Safety should always come first. By taking a few proactive steps, you can save time and ensure you’re only calling for help when it’s truly needed. Just remember: if you’re ever unsure, it’s better to be safe and get a qualified technician on site.
