Electrical Safety at Home: How To Avoid Common Mistakes

Electricity is something we often take for granted—until something goes wrong. Flickering lights, overloaded sockets, and faulty wiring can pose serious risks, including electric shocks, house fires, and expensive repairs. But the good news? Many of these dangers are completely avoidable if you know what to look out for.

At Essjay Electricians, we’ve seen it all—from dangerous DIY fixes to homes overloaded with power-hungry appliances. In this guide, we’ll walk you through the most common electrical safety mistakes and how to protect your home and loved ones.

Let’s dive in! ⚡🏡

🔥 1. Overloading Sockets: A Fire Waiting to Happen
Ever plugged multiple appliances into a single socket using an extension lead? You’re not alone! But overloading a socket can overheat the wiring, leading to electrical fires.

🚨 Signs Your Sockets Are Overloaded:
The socket or plug feels hot to the touch
Lights dimming or flickering when using multiple devices
A burning smell coming from the outlet
The circuit breaker keeps tripping
✅ How to Avoid It:
✔ Only use one high-power appliance per socket (e.g., washing machines, kettles, and heaters should all have their own dedicated outlets).
✔ Check the maximum load rating of your extension lead (most are 13A max).
✔ Invest in surge-protected extension leads to prevent power spikes.
✔ If you frequently need extra sockets, consider installing additional wall outlets (a job for a professional electrician!).

🔌 2. Misusing Extension Leads: The Silent Hazard
Extension leads are meant to be a temporary solution, not a permanent fix for a lack of sockets. Using them incorrectly can lead to fires, electric shocks, and overloaded circuits.

❌ Common Extension Lead Mistakes:
Daisy-chaining multiple extension leads together
Running cables under carpets or rugs (causes heat buildup!)
Using an outdoor extension lead indoors (or vice versa)
Plugging in too many high-wattage appliances
✅ What to Do Instead:
✔ Use wall outlets wherever possible.
✔ If you need more plug points, get an electrician to install additional sockets.
✔ Avoid coiling long extension leads, as this can cause overheating.
✔ Check for damage or exposed wires on extension leads regularly.

⚡ 3. Ignoring Flickering Lights & Faulty Wiring
A flickering light isn’t just annoying—it could be a warning sign of serious electrical issues. Faulty wiring is one of the leading causes of house fires, yet many homeowners ignore the warning signs.

🚨 When to Take Action:
Lights flicker or dim when using appliances
Sparking or buzzing sounds from switches or outlets
A burning or fishy smell near sockets
Scorch marks or discolouration around plug sockets
✅ What to Do:
✔ Don’t ignore the signs—flickering lights can indicate loose connections, overloaded circuits, or failing wiring.
✔ Call a qualified electrician to inspect your home’s wiring.
✔ If your home is over 25 years old, consider an EICR (Electrical Installation Condition Report) to check if your wiring needs an upgrade.

💡 Fact: Rewiring an older home not only improves safety but can also increase energy efficiency and home value.

🛑 4. The Importance of RCDs (Residual Current Devices)
An RCD (Residual Current Device) is a life-saving device that automatically cuts off power if it detects an electrical fault, preventing electric shocks and fires.

🚨 Why Every Home Needs RCD Protection:
✅ Stops electric shocks instantly if there’s a fault
✅ Prevents fires caused by faulty appliances
✅ Protects against wiring faults and surges

✅ How to Check If You Have RCD Protection:
✔ Look at your consumer unit (fuse box)—modern units should have built-in RCDs.
✔ If your home doesn’t have an RCD, it’s time to upgrade your fuse board.
✔ Test your RCD every six months—just press the “Test” button to make sure it’s working.

💡 Don’t have an RCD? Call a qualified electrician to install one ASAP!

🛠 5. DIY Electrical Repairs: Why It’s NEVER Worth the Risk
We get it—DIY can save money. But when it comes to electricity, one wrong move could be fatal. Faulty wiring, incorrect installations, and amateur fixes put your home and family at risk.

❌ Why DIY Electrical Work is Dangerous:
Incorrect wiring can cause short circuits and fires 🔥
Improper installations can lead to electric shocks ⚡
Unqualified work may be ILLEGAL under UK electrical regulations
✅ When to Call a Professional:
✔ Installing new sockets or light fittings
✔ Upgrading your fuse board (consumer unit)
✔ Rewiring or adding circuits to your home
✔ Fixing sparking outlets or tripping breakers

Remember: Saving money on DIY electrical work today could cost you thousands in damages—or worse—later.

🔎 Final Thoughts: Stay Safe, Stay Smart!
Electrical safety isn’t something to take lightly. A few small mistakes can lead to major dangers—but with the right knowledge, you can keep your home and family protected.

🔹 Avoid overloading sockets
🔹 Use extension leads properly
🔹 Don’t ignore flickering lights or faulty wiring
🔹 Install RCDs for added protection
