At JJB Electrical, we frequently receive questions from homeowners across Hertfordshire and Essex about flickering or dimming lights. While it might seem like a minor inconvenience, these issues can sometimes point to larger, more serious electrical problems. In this blog, we’ll explore the most common causes of flickering lights and what steps you should take to address them.
Common Causes of Flickering or Dimming Lights
Overloaded Circuit
An overloaded circuit is one of the most frequent reasons for dimming lights. This occurs when too many appliances are connected to a single circuit, pushing it beyond its capacity. Have you ever noticed that your lights dim when you switch on a high-powered appliance like a microwave, washing machine, or vacuum cleaner? If so, this is likely due to the circuit being overwhelmed by the electrical demand.
What You Can Do: If this happens regularly, it’s essential to consult an electrician to see if the circuit needs upgrading or redistributing the power load across multiple circuits. This can help prevent future issues and ensure your home runs more efficiently.
Loose Wiring or Faulty Connections
Faulty or loose wiring is another common cause of flickering lights. Not only does this cause inconsistent power delivery, but it also poses a serious fire risk. Loose wiring can cause intermittent electrical flow, which manifests as flickering. Over time, this can worsen, leading to more significant damage or even sparking a fire.
What You Can Do: This is not something you should ignore. If you suspect faulty wiring, it's best to turn off the affected circuit and contact a licensed electrician to perform an inspection. Regular maintenance and timely repairs are critical for keeping your home safe.
Faulty Light Switches or Fixtures
Sometimes, the issue isn’t in your wiring but in the light fixture or switch itself. If your light flickers when you toggle the switch, or if the switch feels warm to the touch, it could indicate a worn-out or defective component. This can cause lights to flicker because the connection is no longer secure.
What You Can Do: In most cases, replacing the light switch or fixture solves the problem. However, this should be handled by a qualified electrician to ensure that the wiring is safe and up to current standards.
Voltage Fluctuations
Your home is typically supplied with 230 volts in the UK, and voltage fluctuations beyond this range can cause lights to flicker or dim. Appliances like refrigerators and air conditioners can cause slight fluctuations in voltage, but if these changes are too extreme or frequent, it could signal a larger issue with your home’s electrical system.
What You Can Do: If you’re consistently experiencing voltage spikes or drops, it’s time to call in a professional. This could point to a serious electrical problem that needs immediate attention. A licensed electrician can measure the voltage levels in your home and recommend solutions to stabilize the supply.
