Extension Cords: The Silent Danger in Your Home

They’re tucked behind furniture, powering everything from TVs to toasters — but extension cords are often overlooked when it comes to home safety. While they seem harmless, these everyday items can pose serious fire and electrical hazards if not used correctly.

In this short blog, we're diving into the hidden risks of extension cords, and why you might want to consider more permanent (and safer) solutions in your Bristol home.

Why Extension Cords Can Be Dangerous

Extension cords are designed to provide temporary power solutions — not long-term fixes. Yet in many homes, they’re used continuously for weeks, months, or even years. Over time, this can lead to:

  • Overheating: Extension cords can overheat if too much current is drawn through them, especially when powering high-wattage appliances like kettles, heaters, or microwaves.

  • Electrical fires: According to Electrical Safety First, misuse of extension leads is one of the most common causes of electrical fires in UK homes.

  • Electric shock: Damaged or poorly maintained cords can expose wires, increasing the risk of electric shock.

  • Trip hazards: Loose cords across floors are a leading cause of trips and falls — particularly dangerous for children and the elderly.

Common Extension Cord Mistakes

Here are some of the most frequent (and risky) ways people use extension cords at home:

Daisy-Chaining

Plugging one extension lead into another — known as “daisy-chaining” — may seem like a quick fix, but it dramatically increases the chance of overloading the circuit.

Using the Wrong Cord

Indoor cords aren’t designed to handle outdoor weather, and using the wrong type can lead to electrical faults. Make sure outdoor appliances are powered by weather-rated extension leads.

Overloading

Don’t be fooled by the number of sockets — the total load must still be within the cord’s rated limit. Plugging in a tumble dryer, heater, and phone charger into the same extension is asking for trouble.

Hiding Cords

Running extension cords under rugs or carpets may make them less visible, but it also traps heat and makes them vulnerable to damage — both major fire risks.

How to Stay Safe

The safest solution is always to have more permanent power outlets installed by a qualified electrician. But if you must use extension cords, follow these essential safety tips:

✅ Only use extension cords as a temporary solution.
✅ Always check the power rating — don’t overload it.
✅ Replace damaged or fraying cords immediately.
✅ Avoid daisy-chaining multiple extensions.
✅ Keep cords uncovered and out in the open.
✅ Use extension cords with built-in surge protection.
