Flickering lights can be an occasional annoyance, but when they happen regularly, they may indicate an underlying electrical problem. RB Electrical explains some of the common reasons why household lights flicker and when it is worth calling a qualified electrician.
One simple cause can be a loose or faulty bulb. Checking that the bulb is properly fitted and replacing an old or damaged bulb may resolve the issue. LED bulbs can also sometimes flicker if they are incompatible with an existing dimmer switch.
If multiple lights throughout a property are flickering, the problem could be more significant. Loose connections, faulty wiring or issues within the electrical installation can affect the consistency of the power supply and should be professionally investigated.
Another possible cause is a high electrical load. Large appliances switching on and off can sometimes cause lights to dim or flicker, particularly in older electrical installations.
Flickering lights should not always be ignored, especially when accompanied by buzzing sounds, burning smells, warm switches or frequently tripping circuits. These can indicate a potentially serious electrical fault.
RB Electrical provides electrical fault finding, repairs, testing and inspections to help identify and resolve electrical issues safely. Homeowners experiencing persistent flickering or other unusual electrical behaviour can arrange for the system to be professionally assessed rather than attempting potentially dangerous electrical repairs themselves.
