There comes a time every homeowner will ask themselves, ‘Why are my lights flickering?‘.
And whilst occasional flickering is usually harmless, frequent or unpredictable flickering can signal a more serious electrical issue. What’s more, it could pose a safety risk if left unresolved. So, if your lights flicker regularly or across multiple rooms, it’s best to contact a qualified domestic electrician to investigate sooner rather than later.
5 Reasons Your Lights Are Flickering
In this blog, we share common reasons your lights may be flickering, and when to call an electrician. Keep reading to find out more.
1. Loose Or Faulty Bulbs
Sometimes, the simplest explanation is the right one. Accordingly, if a light is flickering, start by checking the bulb:
- Screw-in bulbs: Make sure they’re fitted snugly into the socket.
- LEDs: If they flicker when dimmed, the issue could be an incompatible dimmer switch.
2. Faulty Light Switches Or Fittings
If flickering continues after changing the bulb, the next culprit could be a loose or worn switch. This is because older fittings can deteriorate over time, which may cause inconsistent connections that lead to flickering lights.
Warning: Don’t try to dismantle or repair the fitting yourself as this can be dangerous. Instead, contact a qualified electrician, like the team at KS Electrical. We can test and replace faulty switches safely and efficiently.
3. Voltage Fluctuations
Do your lights flicker when you use large appliances, like a washing machine or microwave? If they do, it might mean your home is experiencing voltage drops, and you should contact an electrician.This can happen if:
- Your electrical system is overloaded.
- There’s a problem with the main supply line.
Inconsistent voltage isn’t just annoying, but it can actually damage your appliances over time, so it’s important to act fast!
4. Loose Wiring Connections
Over time, wiring connections can loosen due to heat expansion or vibration. Loose wiring is one of the most serious causes of flickering lights, and it’s also a fire hazard.
Some signs you may have loose wiring include:
- Flickering occurs throughout the house, not just one room.
- Lights dim or brighten unexpectedly.
If you notice this, turn off the power to the affected circuit and call an electrician immediately!
5. Issues With The Power Supply
Sometimes, the problem isn’t inside your home at all. In fact, fluctuations or faults in the local power grid can cause brief flickering, especially during storms or high-demand periods. It’s sensible to speak to your neighbours to find out if anyone else is experiencing flickering lights. If they are, contact your electricity supplier to report it.
