Why do my lights flicker - And How to fix it

Have you ever sat at home and noticed your lights flickering? It’s one of the most common electrical issues homeowners face, and while sometimes it’s a simple fix, other times it can signal a bigger problem that requires a licensed electrician.

If you’ve been asking yourself, “Why do my lights flicker?” here are the most common causes and what you can do to stop it.

Common Causes of Flickering Lights

1. Loose or Faulty Bulbs - A loose light bulb connection is the easiest fix - just turn off the power and make sure the bulb is tightened securely. If the problem continues, the bulb itself may be defective.

2. Faulty Switches or Fixtures - Old or worn-out switches and fixtures can cause lights to flicker or dim unexpectedly. Replacing them usually solves the issue.

3. Overloaded Circuits- If your lights flicker when you turn on large appliances (like your , washing machine, or microwave), it may mean your electrical circuit is overloaded. This often requires a Consumer unit upgrade to handle the extra power demand.

4. Voltage Fluctuations - Inconsistent voltage in your home’s wiring can make lights flicker or dim. This is more serious and should be checked by a Registered Electrician near you. https://electricalcompetentperson.co.uk/Search

How to Fix Flickering Lights

• Step 1: Check and tighten your bulbs
