Electricity is something we all rely on—but it’s also one of the most misunderstood aspects of modern life. From DIY misconceptions to outdated advice, there are plenty of myths that could put your safety at risk.
As a leading electrical company in Bristol, here at Brunel Electrical, we believe in empowering our customers with clear, honest information. So let’s bust some of the most common electrical myths!
BUSTED: Even when switched off, many appliances still draw power if they’re plugged in. This is known as “vampire power” or “phantom load”—and it could be silently increasing your electricity bill.
TVs and game consoles left on standby
Laptop chargers plugged in with no laptop
Phone chargers left in sockets
Microwave displays and clocks
Smart speakers and Wi-Fi routers (always on unless switched off at the plug)
Set-top boxes or streaming devices in "sleep mode"
Brunel Electrical Tip: Unplug devices or use smart plugs to cut unnecessary energy usage. It's one of the simplest ways to save power at home.
BUSTED: This is one of the most dangerous myths out there. While it might seem like a simple job—changing a socket, installing a new light fitting, or adding an outdoor plug—the risks of getting it wrong can be severe. Even a small mistake can cause an electric shock, serious injury, house fires, or damage to your appliances.
Worse still, unqualified DIY electrical work can:
Invalidate your home insurance
Fail to comply with UK Building Regulations
Cause problems when you sell your property
Leave you legally liable if someone gets hurt
In the UK, Part P of the Building Regulations makes it a legal requirement for certain types of domestic electrical work to be carried out or certified by a registered electrician. That includes things like installing new circuits, work in bathrooms, and most changes near consumer units.
At Brunel Electrical, we’re fully qualified, experienced, and Part P registered, which means all our work is safe, certified, and compliant. You’ll receive the right paperwork, and you’ll have complete peace of mind knowing it’s done properly.
Bottom line? If you’re not a qualified electrician, don’t risk it. Call a professional.
BUSTED: It’s a common misconception that low-voltage systems—like 12V garden lights or data cables—are completely safe to work on. While the voltage may be lower, the current (amps) can still be high enough to cause harm if mishandled.
Low voltage doesn’t mean zero danger. Depending on the system, you could still face:
Electric shock
Short circuits
Sparks or overheating
Burns and equipment damage
Plus, improper installation can lead to malfunctioning systems, electrical interference, or even voided warranties.
Whether it's for outdoor lighting, smart home devices, or low-voltage heating controls, it's essential that the wiring and equipment are installed correctly and to regulation.
At Brunel Electrical, our fully qualified electricians in Bristol ensure every installation—low voltage or not—is done safely, efficiently, and in full compliance with current UK wiring regulations.
BUSTED: This is a classic myth—and it’s completely false. Lightning regularly strikes the same location multiple times, especially tall structures, trees, and metal installations. Iconic buildings like the Shard in London and the Eiffel Tower are hit dozens of times per year.
Lightning follows the path of least resistance, and anything tall or conductive—like aerials, scaffolding, or power lines—is a prime target.
In the UK, storms may not be as extreme as in other countries, but they still bring a real risk of power surges, which can fry sensitive electronics like TVs, routers, gaming consoles, and computers.
Brunel Electrical Tip:
During a storm, unplug expensive electronics where possible, and consider using surge protectors or a whole-house surge protection device for added security. We can advise on surge protection options as part of our Bristol electrical services.
BUSTED: A flickering light might seem harmless, but it can be a red flag for underlying electrical issues that could pose a fire or safety risk.
Common causes include:
Loose or damaged wiring
Overloaded circuits
A faulty switch or fitting
Voltage fluctuations
Worn or ageing connections at the consumer unit
In some cases, flickering lights are an early sign of a serious fault that could lead to overheating or arcing, both of which increase the risk of electrical fires. This is especially true in older properties or DIY installations.
Don’t ignore it. If your lights flicker frequently or unpredictably—especially when using other appliances—it’s time to get them checked.
As experienced electricians in Bristol, the Brunel Electrical team can quickly identify the cause and carry out any necessary repairs, ensuring your home stays safe and fully functional.
