Even if you think your devices are turned off, they could still be costing you money when on standby.

That’s because this sneaky drain on your electricity bill is called phantom load or vampire power, and it can add up to a surprising amount over time.

While they might seem off, some devices continue to draw small amounts of electricity and consume power, quietly adding to your electricity bills over time.

Standby power refers to the electricity used by electronic devices when they are switched off but still plugged in.

While a single device may use only a few watts, the combined impact across all household electronics can be significant.

Leaving devices on standby is a common habit, but it’s one that comes with a price. Solar Panel experts at GSL have identified three key offenders Brits should switch off to save money this winter.

Grant Store’s Renewable Energy Consultant explained: “Many appliances are designed to consume less power in standby mode, but they don’t stop using electricity altogether.

“Over time, this covert energy usage can result in higher bills, which is an unnecessary burden, especially during the colder months.”

For those looking to trim their energy costs, fully powering down certain appliances could lead to significant savings. Here are the top three devices you should never leave on standby.

Sky or Freeview Boxes

Sky or Freeview Boxes are often left in standby mode for convenience, but they’re one of the biggest energy offenders.

“Boxes may seem harmless when left on standby, but they draw a surprising amount of power even when the TV is off. Fully turning them off at the mains when not in use can result in noticeable reductions to your electricity bill,” says the expert.

PCs

PCs are another appliance to watch out for. Though standby mode speeds up start times, it comes with an energy cost.

“A PC left on standby can add around £10 to £15 to your annual energy bill. It might not seem like much, but when combined with other devices, it all adds up. Shutting down your computer completely when it’s not in use is a simple step to reduce unnecessary energy consumption,” advises the consultant.

Games consoles

Modern game consoles often come with low-power standby settings, but these too consume energy.

“Gaming consoles are a staple in many homes, and while their standby modes are more efficient than before, they still draw power unnecessarily. Turning them off entirely after use is a straightforward way to save energy,” they add.

With the cost of living crisis still affecting many families, every small action to reduce energy usage counts. The Renewable Energy Consultant at GSL concludes: “Switching off appliances at the mains might feel like a small change, but it can make a big difference to your overall energy bills.

“By targeting devices that consume power on standby, households can save money and take a meaningful step toward energy efficiency this winter.”
