When to Call an Electrician: 7 Red Flags in Your Home

We don’t think much about our electrics—until something goes wrong. One day everything’s working fine, the next you’ve got lights flickering for no clear reason, or the kettle trips the power mid-boil.

It’s easy to brush off little electrical quirks as harmless, but some of them are your home’s way of warning you: something’s not right.

And when it comes to electrics, leaving things too long isn’t just inconvenient—it can be dangerous.

Here are seven signs that it might be time to stop guessing and call in a qualified electrician.

1. The Lights Start Acting Up

Ever notice your lights dim for a second when you switch on the microwave or vacuum cleaner? It might not seem like much, but it’s often a sign that something’s not quite right behind the scenes—maybe an overloaded circuit, or wiring that’s seen better days.

Sure, it could just be a loose bulb. But if it happens regularly, or across different rooms, it’s worth having someone come round to check it out.

In the U.S., over 47,000 home fires each year are linked to electrical failures or faults. So if you’re seeing flickers or dips in brightness, don’t ignore them. It’s not just about the lights—it’s about keeping your home safe.

2. Your Breakers Keep Tripping

A tripped circuit now and then is perfectly normal—that’s what your fuse box is there for. But if you’re constantly flipping the same switch back on, especially when using the same appliance, there’s a problem.

It could be that the circuit’s overloaded, or the wiring’s worn out. In older houses, the whole fuse board might be outdated and struggling to cope with today’s energy use.

Rather than resetting things ten times a week, it’s smarter—and safer—to call someone in to sort it properly.

3. Something Smells… Off

A faint burning smell coming from a plug or switch is never a good sign. Neither is a socket that feels unusually warm, even if nothing is plugged into it at the time.

Don’t try and ‘wait it out’. These are classic signs of overheating, loose connections, or even internal arcing—things that can quickly lead to a fire.

If something smells burnt, turn off the power to that area and ring an electrician right away. It’s not worth the risk.

4. You’re Using Extension Leads Everywhere

We’ve all done it—plugged one extension into another because the TV, Wi-Fi router, phone charger, and lamp all need juice from the same corner.

But if your whole house is running on daisy-chained extension leads, it’s not sustainable—or safe.

Older homes weren’t designed with dozens of modern devices in mind. Over-reliance on multi-plugs often means the wiring behind the walls is under pressure. That’s where things start to go wrong.

An electrician can add new sockets in the right places and make sure your system’s not running beyond its limit.

5. You Live in an Older House With Old Wiring

If your home hasn’t been rewired in the last 30 or 40 years, it’s time to check what’s behind the walls. Some houses still have aluminium wiring or rubber-coated cables—both of which are outdated and can become brittle over time.

Old wiring might still “work”, but that doesn’t mean it’s safe. You might notice it through little things—like frequent bulb blowouts or sockets that don’t quite sit right. Left unchecked, the risks increase.

It’s not always about a full rewire, either. A simple inspection could tell you whether a few upgrades would keep you safe for years to come.

6. Sockets or Switches Aren’t Working Like They Used To

When a plug falls out of a socket too easily, or a light switch makes a strange noise, you might shrug it off. But loose sockets, buzzing switches, or dead power points usually mean there’s wear or damage beneath the surface.

You might be tempted to wiggle things or patch it yourself. Don’t. Those small warning signs are often early clues that something serious is going on, especially if you hear cracking, buzzing, or smell something odd.

Let a professional check it—it’s a 20-minute job that could prevent a disaster.

7. You’re Planning a Renovation or Adding Big Appliances

Thinking about installing an EV charger? Reworking the kitchen? Adding a summer house at the end of the garden? These all come with extra electrical load—whether or not you realise it.

Rather than getting halfway through and realising your wiring can’t handle the new setup, it’s best to get an electrician involved at the start.

They’ll tell you what needs upgrading (if anything), how to distribute the load safely, and make sure you’re not going to blow fuses every time you use the oven and kettle at once.

The Bottom Line

Electrical problems don’t fix themselves. And while it’s tempting to ignore flickers, smells, or sockets that only work when you hold them just right, these are signs something needs attention.

Calling an electrician doesn’t mean you’re overreacting—it means you’re avoiding bigger trouble later.

Whether it’s a minor tweak or a full system upgrade, having the peace of mind that everything’s working safely is worth it.

If in doubt, trust your instincts. You don’t need to wait for sparks to fly to know when something’s off.
